Frequently Asked Questions - MURELLE REVOLUTION 30 SIME

How do I reset the boiler after a fault?

Press and hold the reset button (usually marked R) for 3 seconds until the fault code disappears. If the fault persists, refer to the manual or call a technician.

What does error code E01 mean?

Error E01 indicates flame detection failure. Check gas supply, ignition electrode, and flame sensor. Ensure the gas valve is open.

How often should I service the boiler?

It is recommended to have an annual service by a Gas Safe registered engineer to maintain efficiency and safety.

Can I use the boiler without central heating?

Yes, you can select summer mode (only DHW). Switch the mode selector to the sun symbol or DHW-only setting.

What is the ideal water pressure?

The system pressure should be between 1.0 and 1.5 bar when cold. If below 1 bar, repressurize using the filling loop.

How do I adjust the hot water temperature?

Use the DHW temperature dial on the control panel. Turn clockwise to increase, counterclockwise to decrease (range 30-60°C).

What type of gas does the boiler use?

The boiler is factory-set for natural gas (G20) but can be converted to propane (G31) with a conversion kit by a qualified installer.

Why is the boiler making a banging noise?

A banging noise may be due to kettling (limescale build-up) or trapped air. Bleed radiators and consider a system flush or descaling.

How do I turn off the boiler for extended periods?

Set the mode to off or standby using the main power switch. For winter, leave frost protection active if needed.

1 USING THE BOILER MURELLE REVOLUTION

1.1 Main control panel (remote control)

The main control panel (PCP) allows all of the necessary adjustments to be made to Murelle Revolution and to the connected systems. It also serves as a main room thermostat and can therefore be used by all operators, users, authorised maintenance technicians and the technical service for the operations for which each of these figures is authorised, as described in detail in the relevant sections. It communicates with the boiler control panel with an unpolarised bus line and OpenTherm protocol, and with the heat pump control panel with a RS485 polarised ModBus two-wire line. It is equipped with a volt free input for remote control, where relevant (GSM-Dialler/WiFi).

• turn the encoder to modify the "Data/value" on the basis of the required time
• press the click encoder to confirm the modification and move to the next "Data/value"

- continue in this way until all the necessary modifications have been made for each day of the week or group of days.

NOTE: The user must work in a CIRCULAR manner, meaning ALWAYS MOVING FORWARDS, even if a mistake is made.

CAUTION

If NO time band is required, set the start and stop times of that band to the same value (e.g. [3] 14:00-14:00).

• Once the modification has been made, press the Confirm button to go back to "Single days" or "Group of days"
• press the Esc button to go back to the "Main screen".

1.3.2 Holidayfunction

This function allows the user to deactivate both heating and hot water production during a "set and activated" holiday period, during which the antifreeze function can be active (if set).

To set the holiday function from the "Main screen":

• press the Mode button
• press the click encoder to confirm one of the Summer or Winter function mode
• turn the encoder to select "Holiday function"

- press the encoder click to confirm the "Holiday function" (Holiday function) and go into the modifiable area

- turn the encoder to modify the "Data/value" which is highlighted - press the click encoder to confirm the modification and move to the next "Data/value"

• turn the encoder to modify the "Data/value" on the basis of the holiday start date
• press the click encoder to confirm the modification and move to the next "Data/value"
• continue in this way until all the necessary modifications have been made..

NOTE: The user must work in a CIRCULAR manner, meaning ALWAYS MOVING FORWARDS, even if a mistake is made.

- When all modifications have been made, press the Confirm button to go back to "Holiday function" - press the Esc button to go back to the "Main screen".

1.3.3 Fault warnings

If a fault occurs, the screen "Anomaly in progress" (Fault in progress) will appear in place of the "main screen". For the main fault codes, a brief description and suggestions for the user are displayed, based on the seriousness and the frequency with which the fault reappears.

The fault may be transient (volatile) or it may cause an appliance block.

To restore normal operating conditions:

• if the fault is transient, eliminate the cause of the fault
• if the fault causes a block, remove the cause of the fault and then press the Reset button.

If there is "no water in the system" or "low water pressure in the system" there is a request to fill the system and then to press the Confirm button rather than the Reset button.

CAUTION

4 DESCRIPTION OF THE APPLIANCE

4.1 Characteristics

Murelle Revolution is an innovative Ccass A++ wall-mounted boiler designed by Sime Ltd SOLELY for space heating and producing domestic hot water.

The appliance is made up of a latest-generation sealed condensing gas boiler and a heat pump.

Murelle Revolution can ONLY operate if it is connected to the outdoor probe supplied with the appliance; if the outdoor probe is NOT connected, Murelle Revolution will NOT work.

The wall the appliance is mounted to must be able to support its weight, and preferably be an outside wall, to simplify installing the air inlet and outlet pipes.

Murelle Revolution can produce water for a heating system to a temperature of up to 75^ C. To obtain maximum performance from Murelle Revolution, the delivery temperature MUST NOT exceed 65^ C and the return temperature must not be above of 45^ C.

The main design choices made by Sime Ltd for Murelle Revolution boilers are:

• use of a sealed boiler with a total pre-mix microflame burner combined with a steel heat exchanger body and a rapid heat exchanger for DHW
• use of a modulating circulation pump
• use of a heat pump (HP), which is supported by the boiler to produce heat, and can operate separately or together with the boiler, according to the temperature detected by the outdoor probe
• a Main control panel (remote control) which serves both as an room thermostat and as a command and control device, a microprocessor, with bus protocol to manage the Murelle Revolution and related system
• use of a main evaporator with a patented smoke evaporator in series and a plate heat exchanger to transmit the heat to the water in the system. This allows the heat pump to operate with an average COP of 4.
• the option of being connected to room thermostats or chrono-thermostats for the zone.

The command board also has an internal connection where an expansion which can control the external relays can be inserted.

Murelle Revolution also has the following functions:

• the anti-freeze function which is activated automatically if the temperature of the water inside the boiler falls below the value set under "PAR 10" and if the outdoor temperature falls below the value set under "PAR 11"
• anti jamming function of the pump and diverter valve, this activates automatically every 24 hours if no request for heat has been made
• the chimney sweep function lasts 15 minutes and makes the job of the qualified technician easier when measuring the parameters and combustion efficiency
  – domestic hot water comfort function which allows the time necessary for the hot water to become available to be reduced and ensures that the temperature is stable
• screen display of the operating and self-diagnostic parameters with error code display when the fault occurs. This makes repair interventions easier and allows appliance operation to be restored correctly.

4.2 Operation summary

4.2.1 Heating

When there is a heating request from the main control panel (PCP) or from an room thermostat for the zone (TAZ), where there are no alarms and where the outdoor temperature is at least -7°C, the heat pump is activated (HP).

After a set period of time, calculated using an algorithm according to the current outdoor temperature, the gas boiler also starts up to help heat the water in the system and respond to the current request for heat.

When the system water temperature reaches the required value, also calculated using a specific algorithm for the gas boiler, the boiler stops and ONLY the heat pump continues to operate, until the heating request has been satisfied; after which, the heat pump also stops.

CAUTION

If, when there is a heating request, the outdoor temperature is below -7°C (e.g. -10°C), only the gas boiler is activated and the heat pump remains inactive.

4.2.2 Domestic Hot Water (DHW)

When there is a request for DHW, providing there is no heating request from the room thermostats, the diverter valve prepares to direct the flow of water towards the plate heat exchanger and the boiler starts up to respond to the request.

Should there be a request for heat at the same time, the heat pump stops and the boiler operates as described above. Once the DHW request has been satisfied, standard heating operation resumes.

4.3 Check and safety devices

The Murelle Revolution boilers are equipped with the following check and safety devices:

• thermal safety thermostat 100°C
• 3 bar relief valve
• heating water pressure transducer
• delivery sensor
• DHW sensor

WARNING

When moving the appliance and removing the packaging, the user must:

• respect the maximum weight restrictions for lifting per person
• use suitable tools and safety devices.

5.4 Ventilation requirements

The room where the appliance is to be installed must comply with the technical regulations and legislation in force. No aeration vents are required because the approved installation is ONLY "TYPE C" (refer to the regulations). Moreover, it must be made in a way that prevents noise as far as possible during the appliance's operation.

The minimum temperature of the installation room must NOT be lower than -5 °C.

CAUTION

• Make sure that the appliance is protected against direct sunlight, the weather and damp and wet conditions.
• Before assembling the appliance, the installerMUST make sure that the wall supports the weight.
• Remember to consider the space needed in order to access the safety/adjustment devices and to carry out maintenance interventions.

APPROXIMATE MINIMUM DISTANCES

CAUTION

Observe the necessary height (A), to be defined during installation, for making the plumbing and gas connections.

CAUTION

In the case of flammable walls and penetrations, an insulating protection should be placed between the wall and the flue duct.

5.5 New installation or installation of a replacement appliance

The boiler must be installed in a fixed location and only by specialized and qualified person in compliance with all instructions contained in this manual.

The installation of this boiler must be in accordance with the relevant requirements of the current Gas Safety (installation and use), the local building regulations and I.E.E. wiring regulations. Detailed recommendations for air supply and fluing are given in BS5440.

The following notes are for general guidance: it is not necessary to have a purpose provided air vent in the room or compartment in which the appliance is installed.

CAUTION

It is a condition of the warranty that the boiler is installed in accordance with the instructions in this manual. The boiler must be registered with Gas Safe Register, the Benchmark record must be completed and the boiler is serviced annually and recorded in this manual.

CAUTION

If the domestic water supply is metered or should a water meter be added at a later time, a small expansion vessel should be included in the domestic water pipework.

5.6 Cleaning the system

Before installing the appliance on a newly constructed system or replacing a heat generator on an existing system, it is important that the system is thoroughly cleaned to remove sludge, slag, dirt, residue etc.

Before removing an old heat generator from an existing system, it is recommended that the user:

• puts a descaling additive into the water system
• allows the system to work with the generator active for a few days
• drains the dirty water from the system and flushes the system with clean water once or more than once.

If the old generator has already been removed or is not available, replace it with a pump to circulate water in the system and then proceed as described above.

Once cleaning operations have been carried out and before installing the new appliance, it is recommended that a fluid is added to the water system to protect it from corrosion and deposits.

CAUTION

• For further information on the type of additive and usage, please contact the appliance manufacturer.
• Please note that IT IS RECOMMENDED to install a Y-strainer on the return (R) of the heating system.
• It is advisable to install a defangator, not included with the appliance, upstream of the Y filter to collect and separate impurities in the system.

5.7 Characteristics of feedwater and system treatment

• All recirculatory systems will be subject to corrosion unless an appropriate water treatment is applied. This means that the efficiency of the system will deteriorate as corrosion sludge accumulates within the system, risking damage to pump and valves, boiler noise and circulation problems.
• Before connecting the boiler the associated central heating system must be flushed in accordance with the guidelines given in BS 7593 "Treatment of water in domestic hot water central heating systems".
• Sime Ltd recommends only the use of FERNOX products for the flushing and final treatment of the system water. This is particularly important in hard water areas. Failure to flush and add inhibitor to the system may invalidate the appliance warranty. Artificially softened water must not be used to fill the heating system. Naturally soft water areas can corrode aluminium heat exchangers. Adding Fernox F1 or Mb-1 will guard against corrosion.
• Sime Ltd promote the fitting of TF1 System filter with any new boiler installation.
• It is important to check the inhibitor concentration after installation, system modification and annually on a service visit in accordance with the manufacturer's instructions. (Note on benchmark service record this has been complete). Test kits are available from inhibitor stockists; the return of the Fernox test report should be kept with the Benchmark to validate warranty.
• Where Central heating systems are susceptible to freezing a mixture of inhibitor and anti-freeze should be added in accordance with the DWTA code of practice and the Manufactures instructions.
• The addition of sealing agents to system water is not recommended because deposits can be left in heat exchanger causing circulation issues.

5.8 Boiler installation

Before mounting the Murelle Revolution boiler on the wall, check that:

• the wall is solid enough to support the weight
• the required minimum clearance zones are respected
• it is an outside wall or one which allows the user to respect the maximum length of the air inlet and outlet pipes ( = 160/200 mm) (6 metres in total)
• the smoke outlet allows the user to respect the maximum length of the pipe (maximum permitted load loss)
• the water and gas supplies are easily accessible.

NOTE: Sime Ltd has created the "Wall-mounting bracket" KIT code 8081224 (not supplied with the product) to considerably reduce vibrations and noise in installations where these characteristics are important (e.g. internal rooms). If the kit is used, for the drilling operations refer to the instruction sheet accompanying the kit.

CAUTION

Attach the four circular spacers (1) supplied in front of and behind the fittings (2).

NOTE: if the "Wall-mounting bracket" kit code 8081224 is used, refer to the instruction sheet accompanying the kit.

Then:

• mark the two points where the holes are to be made to insert suitable expansion plugs that support the weight of the boiler
• mark the points where the holes (Ø 164 mm) are to be made to pass the air inlet and outlet and smoke outlet pipes through

* if the "Wall-mounting bracket" kit code 8081224 is used, the boiler will be mounted roughly 20 mm away from the wall.

- mount the boiler safely on the wall.

CAUTION

• The boiler should be located observing the required clearances, and provide safe, adequate service access.
• The manufacturer is not responsible for any damage to people, animals or objects following incorrect mounting of the appliance.

CAUTION

It is important that the device is perfectly vertical and horizontal. Use a spirit level or other suitable tool to check that it is perfectly vertical and horizontal. Where necessary, insert suitable spacers to install the unit in the correct working position.

5.9 Plumbing connections

The plumbing connections have the following characteristics and dimensions.

*if the "Wall-mounting bracket" kit code 8081224 is used, the boiler will be mounted roughly 20 mm away from the wall.

    C --> D["Step 4: Cut the cylindrical tube with ring handle"]

5.12 Gas supply

Murelle Revolution boilers leave the factory prearranged for gas G20 and can also work with G31 without the need for any type of mechanical conversion. Simply select parameter "03" (see "Parameter setting and display") and set the type of gas to be used.

Moreover, they are configured for working with G20 gas with a gas mixture containing up to 20% hydrogen H _2 .

If changing the type of gas to be used, carry out the entire appliance "COMMISSIONING" phase.

As a condition of the warranty and to ensure correct operation and efficiency, it is important that the boiler is serviced every 12 months, within 30 days of the anniversary of the installation date ensure the required information is recorded in the Gas Boiler System Service Interval Record (page 84) (Benchmark).

The gas connection must be made using seamless steel or copper tube.

Where the piping has to pass through walls, a suitable insulating sleeve must be provided.

When sizing gas piping, from the meter to the boiler, take into account both the volume flow rates (consumption) in m3/h and the relative density of the gas in question.

The sections of the piping making up the system must be such as to guarantee a supply of gas sufficient to cover the maximum output available from the boiler, limiting pressure loss between the gas meter and any apparatus being used to not greater than 1.0 mbar for family II gases (natural gas).

An adhesive data badge is sited inside the front panel; it contains all the technical data identifying the boiler and the type of gas for which the boiler is arranged.

WARNING

Once installation has been completed, check that the joints are air tight as indicated in the installation Standards.

CAUTION

It is recommended that the gas line has a suitable filter.

CAUTION

5.13.5 Holes for air inlet/outlet

Two holes are required for the appliance in the wall to channel the air inlet (1) and outlet (2) pipes outside.

• Carefully mark the centre of the holes to be made

Given the substantial size of the holes to be made in the wall, we recommended that suitable equipment (a core drill) be used, together with a suction system to limit the amount of dust and rubble.

CAUTION

The holes for channelling the inlet and outlet pipes outside must be slightly inclined downwards, to prevent any water coming in through the ducts.

WARNING

When making the holes for channelling the inlet and outlet pipes outside, the majority of the material may be expelled outside; it is therefore important to check that it does not hit people or objects below as it falls. To avoid damaging the external plastering as far as possible, take extra care in the final stages of making the hole.

CAUTION

The manufacturer is not responsible for any damage to people, animals or objects following incorrect installation of the air inlet and outlet system.

5.13.6 Fitting the air ducts

• Cut the pipe (1) so that M1 = space between the wall and the elbow (A) + approximately 45 mm (insertion length of the pipe (1) in the elbow (3))
• cut the pipe (2) so that M2 = 160 + wall thickness (B) + space between the wall and the elbow (A) + approximately 60 mm (insertion length of the pipe (2) in the elbow (3))
• insert the rings (4) inside the pipe (1), then the pipe (1) in the elbow (3) and the assembled unit in the support (5)
• install the pipe (2), from the outside, until it is fully inserted in the elbow (3).

NB.: Ensure that the opening (6) is completely free so that any rain water can be drained.

5.14 Mounting the main control panel (remote control)

CAUTION

Before mounting the main control panel on the wall, the cables below must be prepared; these cables will then be connected to the terminals inside the control panel itself:

• Mod-Bus communication cable

6.7 Checks

6.7.1 Chimney sweep function

The chimney sweeper function is used by the qualified maintenance technician to check the mains gas pressure, detect the combustion parameters and to measure the combustion efficiency. A combustion analysis should not be conducted until a satisfactory inlet working pressure test has been completed.

This function lasts 15 minutes and is activated by proceeding as follows:

- if the front panel has not already been removed, open the two catches [1], unscrew the two screws [2], pull the front panel [3] forwards and release it from the top by lifting it.

• remove the screws (4) securing the control panel (5)
• move the panel (5) upwards (a) but keeping it in the side guides (6) to the end of travel
• bring it forwards and down (b) until it is horizontal

• isolate the gas cock
• loosen the screw of the "mains pressure" point (7) and connect a pressure gauge

Technical line drawing of a mechanical assembly with no visible text or symbols

• press the button > to make the boiler operate at maximum power "Hi" and check that the mains gas pressure value on the pressure gauge is correct.
• press the button < to make the boiler operate at minimum power "Lo". The message "Lo" will appear on the display together with the flashing symbols ] and n

• take the combustion data reading
• press the button ⏻R to exit the "Chimney sweeper Procedure". The boiler water delivery temperature will appear on the display

- disconnect the pressure gauge, carefully close the pressure point (6), test for gas tightness, put the control panel back to the original position and refit the front panel (2). Now conduct a flue gas analysis as detailed in APPENDIX 2.

Gas supply pressure

Type of gas G20 G31
Pressure (mbar) 19 36

CAUTION

During the annual check of the appliance, the maximum CO must be below 700 ppm (0% O2). If the CO value is higher, perform maintenance. Also check the CO limit in accordance with national legislation.

NOTE: There are negligible losses of working gas pressure attributable to the boiler as the gas cock is connected directly to the gas valve.

6.8 Domestic hot water comfort function (preheating)

Murelle Revolution models have a "domestic hot water comfort" function which ensures the best performance in terms of domestic hot water, reducing the time necessary for the hot water to become available and ensuring that the temperature is stable.

To activate the function:

• select parameter"PAR 22" (see "Parameter setting and display") and set it to value 1
• exit parameter settings and press button+ for approximately 5 seconds until the symbol _i appears on the display and begins to flash indicating that the function has been activated.

To deactivate the function:

- press button + again for approximately 5 seconds until the symbols ✕ and RESET appear on the display and begin to flash indicating that the function has been deactivated.

6.9 Gasconversion

The Murelle Revolution models can work at G20 or at G31 without any mechanical transformation. It is only necessary to select parameter "PAR 03" (refer to "Parameter setting and display") and set it on the basis of the type of gas to be used, and then fully perform the "Automatic self-calibrating procedure" phase described on page 56.

CAUTION

Conversion may ONLY be carried out by Professionally Qualified Personnel.

CAUTION

If the gas supply is changed from G20 to G31, mark the box on the TECHNICAL DATA PLATE.

Benchmark Commissioning & Warranty Validation Service Record

It is a requirement that the boiler is installed and commissioned to the manufacturers' instructions and the data fields on the commissioning checklist completed in full.

To instigate the boiler warranty the boiler needs to be registered with the manufacturer within one month of the installation. The warranty rests with the end-user (consumer), and they should be made aware it is ultimately their responsibility to register with the manufacturer, within the allotted time period.

It is essential that the boiler is serviced in line with the manufacturers' recommendations, at least annually. This must be carried out by a competent Gas Safe registered engineer. The service details should be recorded on the Benchmark Service and Interim Boiler Work Record and left with the householder. Failure to comply with the manufacturers' servicing instructions and requirements will invalidate the warranty.

www.hhic.co.uk

This Commissioning Checklist is to be completed in full by the competent person who commissioned the boiler as a means of demonstrating compliance with the appropriate Building Regulations and then handed to the customer to keep for future reference.

Failure to install and commission according to the manufacturers' instructions and complete this Benchmark Commissioning Checklist will invalidate the warranty. This does not affect the customer's statutory rights.

* All installations in England and Wales must be notified to Local Authority Building Control (LABC) either directly or through a Competent Persons Scheme. A Building Regulations Compliance Certificate will then be issued to the customer.

APPENDIX 1 (GUIDANCE HHIC)

Manufacturer's Instructions

The latest manufacturer's instructions shall be followed for the correct connection of the condensate discharge pipe from the boiler as this may vary due to the design of the boiler. For example, a trap is not required in the condensate discharge pipework if there is a trap with a minimum condensate seal of 75 mm incorporated into the boiler.

Internal Condensate Pipe Discharge Termination

Internal condensate discharge pipework shall be a minimum of 19mm ID (typically 22mm OD) plastic pipe or as per manufacturer's instructions and this should "fall" a minimum of 45mm per metre away from the boiler, taking the shortest practicable route to the termination point.

(45mm as per BS6798, 52mm per metre as per industry practice is specified in the following diagrams)

To minimise the risk of freezing during prolonged sub-zero conditions, an internal "gravity discharge point" such as an internal soil stack (preferred method), internal kitchen, utility room or bathroom waste pipe e.g. from a sink, basin, bath or shower shall be adopted, where possible.

Note - Use a suitable permanent connection to the foul waste pipe. Figures 1, 2(a), 2(b) show appropriate connection methods.

Internal Condensate Pipe Discharge Termination

When connecting to existing pipework it is critical to review the existing installation to ensure the existing pipework is appropriate for condensate discharge having been run correctly and fully insulated and sealed if this is an external or internal termination.

The possibility of waste pipes freezing downstream of the connection point shall be considered when determining a suitable connection point - e.g. a slightly longer pipe run to an internal soil stack may be preferable to a shorter run discharging directly through the wall to an external drain.

Note - Where "gravity discharge" to an internal termination is not physically possible (e.g. the discharge point is above the appliance location, or access is obstructed by a doorway), or where very long internal pipe runs would be required to reach a suitable discharge point, then a condensate pump shall be used.

External waste pipework shall be:

• Only used to take the condensate waste away and no other waste must be connected to keep the pipework free from restrictions or blockages
  • Insulated with waterproof UV resistant material.
• All joints sealed correctly stopping water getting between the insulation and waste pipe
• Terminated below the grid but above the water line and a drain/leaf guard fitted.
• Cut at 45 degrees where it terminates into the grid and insulated to the tip of the pipe.
• A minimum thickness of 13mm insulation is recommended for minimum 32mm OD solvent pipe work and fittings
• Where the insulation passes through the wall with a flexible seal for expansion and contraction is required, to stop any moisture getting between the insulation and waste
  pipe. This also stops any moisture penetrating through the wall, providing seal supporting energy efficiency

Condensate Pump

Use of a Condensate Pump to an Internal Termination

Condensate can be removed using a proprietary condensate pump, of a specification recommended by the boiler or pump manufacturer. In order to minimise the risk of freezing during prolonged sub-zero spells, the preferred method is internal to the property for terminating the boiler condensate pump to a foul water discharge point should be adopted such as an internal soil stack (preferred method) All waste pipework must be as vertical as possible to take condensate water as fast and as hot as possible to the internal soil stack Any waste pipework being fitted in an unheated area must be enlarged to 32mm OD, insulated and sealed correctly (solvent weld pipe and fitting). UV is not required as fitted internally

November 2023 Issue 3.0

HEATING & HOTWATER INDUSTRY COUNCIL

External Connectionst

External Connections

Only fit a correctly insulated external boiler condensate drain connection if an internal gravity or pumped connection is impractical to install.

The pipe work from the boiler shall be of a minimum 19mm ID or if in an unheated area increased to 30mm ID (typically 32mm OD) solvent weld of as per manufacturer's instructions and the condensate discharge pipe shall be run in a standard drainpipe material, e.g. poly (vinyl chloride) (PVC), un-plasticized poly (vinyl chloride) (PVC-U), acrylonitrile butadiene-styrene (ABS), polypropylene (PP) or chlorinated poly (vinyl chloride) (PVC-C).

Note - Fixing centres for brackets should be a maximum of 300mm for flexible pipe and 500mm for solid pipe and manufacturer's recommendations should be followed.

The condensate pipe should be run internally as far as possible before going externally and the pipe diameter shall be increased to a minimum of 30mm ID (typically 32mm OD) if not already, if in an unheated, area before it passes through the wall. The angle of the pipe shall slope downwards by at least 3 degrees as it passes through the wall to assist in maintaining a good velocity as the condensate exits the building.

The external pipe run shall be kept as short as possible to a maximum of 3 metres, taking the most direct and "most vertical" route to the discharge point, with no horizontal sections in which condensate might collect. The external condensate and pipework inside the cavity wall must be insulated to manufacturers instructions

External Connections

Connecting to a rain water downpipe/External Soil Stack

When a rain water downpipe is used as the termination (NB only permissible if this downpipe passes to a combined foul and rainwater drainage system) an external air break shall be installed between the condensate discharge pipe and the downpipe to avoid reverse flow of rainwater into the boiler should the downpipe itself become blocked, flooded or frozen.

Figure 4 shows a suitable connection method. Pipe insulation should be fitted.

External Termination of the Condensate Pipe

Where the condensate discharge pipe is terminated over an open foul drain or gully, the pipe should terminate below the grating level, but above water level, in order to minimise "wind chill" at the open end. Pipe drainage and resistance to freezing will be improved if the termination end of the condensate pipe is cut at 45 degrees as opposed to a

The use of a drain cover (such as those used to prevent blockage by leaves) shall be fitted to offer further protection from wind chill. Figure 4 (following page) shows a suitable connection method. Where the condensate drain pipe terminates in a purpose-designed soakaway any above-ground section of condensate discharge pipe should be run and insulated as described above.

Other considerations

Unheated Areas in Buildings

Internal condensate drainage pipes run in unheated areas such as lofts, basements and garages shall be treated as external connections and insulated accordingly. Weather proof materials may not be necessary but where separate sections of insulation join together, including elbow joints then these should be connected, insulated and sealed correctly to prevent them coming apart with a suitable material to help prevent freezing.

Insulation Materials

Insulation used for external condensate pipes, shall have an outer coating that is weather proof, and UV resistant. Use a minimum of 13mm thick insulation for 32mm external pipes. Ensure all pipework is insulated and sealed correctly

Use of Air Breaks In Condensate Discharge Pipes

Heating engineers should follow manufacturer's instructions on the use of air breaks in condensate discharge pipes. An air break is normally required for both rainwater and soak away connections. Refer to manufacturer's instructions for further details on for air break requirements.

Soakaway

If a soakaway is the only alternative to discharge the condensate an external insulated and sealed air break is required. This will allow water to be discharged from the condensate pipe should the soakaway become saturated, and will allow the boiler to continue to operate. Note: If water is discharged from this 'overflow', then increasing the volume of the soakaway pit should be considered.

Alternative Solutions

Cold weather protection

Cold weather protection methods approved or endorsed by boiler manufacturers and/or service organisations may be adopted if these are considered suitable by the parties involved. It is the responsibility of the manufacturer of these products to ensure they have completed the necessary testing or calculations to ensure the product offers suitable protection to prevent the condensate pipe from freezing. The product manufacturer should provide information as to what level of external temperature and for what time period the product can protect against sub-zero temperatures, i.e. -15°C for 48 hours.

Electric Trace Heating

Trace heating with an external thermostat can be fitted to the external condensate pipe to raise the temperature of the condensate pipe in freezing conditions. Trace heating takes the form of an electrical heating element run in physical contact along the length of the condensate pipe. The pipe still needs to be insulated and sealed correctly to retain heat losses from the pipe. Heat generated by the element then maintains the temperature of the pipe. If such a system is used then the installation instructions of the trace heating manufacturer and any specific recommendations regarding pipe diameter, insulation, etc. should be followed. All other relevant guidance on condensate discharge pipe installation should also be followed.

Auxiliary Syphon – Fitted Internally

Auxiliary siphons fitted inside the premises assist with the siting of the boiler where an external condensate pipe must be fitted. The storage capacity of the auxiliary siphon increases the volume of condensate discharge reducing the risk of freezing. A further reduction in the potential for the pipe to freeze is achieved when combined with the external insulation requirements and sealing correctly. The aim is to keep the condensate discharge running as fast and as hot as possible, this heats the waste pipe and prevents freezing.

Note – Annex A details remedial actions for householders which can be taken if a condensate discharge pipe freezes. This may result in requests for alteration to condensate discharge pipework, in which case the guidance above should be followed.

Frozen Condensate Information Leaflet – Our customer information guide on frozen boiler condensate discharge is also available for download. It includes a condensate assessment form, for engineers to complete and advice to customers during extreme cold weather conditions. www.hhic.org.uk/resources.

Dear Householder,

Your heating engineer has noted that your boiler condensate discharge pipe may be at risk of freezing in prolonged, and extreme cold weather conditions. In recent years we have seen temperatures as low as -20*c in some parts of the UK.

The concern is that your pipe runs externally or in an unheated space for at least some of its length and is liable to freeze in these extreme temperatures as it is not installed in line with the latest guidance, to help guard against freezing. If your pipe freezes, it will cause your boiler to go into “shut off” at a time when you need your heating and hot water the most.

Your heating engineer will advise you on the solutions available to reduce the risk of your pipe freezing, including running the discharge pipe to an internal drainage point (the preferred method if you have an internal soil stack), or installing one of the available products designed to give you added protection against freezing conditions. They will also clearly identify the external condensate discharge pipe for your future reference and may apply an identification label or tape.

Annex A

Thawing Frozen Condensate Pipes

Below is an explanation of what you would need to do to resolve the problem in the event that the pipe was to freeze. We would highly recommend getting a professional to assess the situation and resolve the problem by upgrading the condensate. If you do try to unfreeze your condensate, please take care as there are risks due to the related weather conditions.

1. Locate the blockage

The Condensate discharge pipe usually freezes at the most exposed points outside, such as the open end of the pipe, at a bend or elbow, or where there is a dip in the pipe where condensate can collect. (If the condensate has no insulation there may be an extensive frozen area)

2. Thaw the Frozen Pipe

The Condensate can be thawed in a number of ways. By applying a hot water bottle, a microwaveable heat packs around the blockage or by pouring warm water onto the pipe. Do not use boiling water. Do not use water if your condensate discharge pipe is not easily reached from ground level, Do not put yourself at any undue risk. Seek assistance and engage a professional heating engineer. Be aware that if you are pouring water onto the pipe this can also quickly freeze on the ground, causing a slip hazard.

3. Reset/ Restart the boiler

Once the frozen blockage has been cleared, the boiler will usually need to be reset, and advice on how to do this can be found in the user instructions manual for your boiler. Normally this will involve simply pressing a reset button on the front of the boiler, or in some cases by isolating the electrical supply to the boiler and switching it back on
