Frequently Asked Questions - CBP Matic 18 Baxi

How do I reset the Baxi CBP Matic 18 boiler?

Press the reset button on the control panel for 3 seconds. If the boiler does not restart, check for a gas supply issue or contact a qualified engineer.

What should I do if the boiler loses pressure?

Locate the filling loop (usually a flexible hose) and open the valve slowly until the pressure gauge reads between 1 and 1.5 bar. Close the valve and check for leaks. If pressure drops frequently, there may be a system leak.

How often should I service my Baxi CBP Matic 18?

An annual service by a Gas Safe registered engineer is recommended to ensure efficient and safe operation. This includes checking flue, burner, heat exchanger, and controls.

Why is my boiler not producing hot water?

Possible causes: low water pressure, faulty diverter valve, or air in the system. Check the pressure gauge; if low, repressurize. If problem persists, call a professional.

What type of flue does the CBP Matic 18 use?

It uses a room-sealed concentric flue (60/100 mm) that draws air from outside and expels exhaust gases. Ensure the flue terminal is not blocked.

Can I install the boiler myself?

No. Installation must be carried out by a Gas Safe registered engineer to comply with regulations and maintain warranty validity.

How do I bleed my radiators?

Turn off the heating, use a radiator key to open the bleed valve slightly, release air until water comes out, then close. Check boiler pressure after. Repeat for all radiators.

What does the 'lockout' light mean?

The lockout indicator signals that the boiler has detected a fault and shut down. Refer to the manual for error codes. Common causes: ignition failure, gas supply interruption, or overheating. Reset after checking.

How do I adjust the heating temperature?

Use the temperature control knob on the boiler panel to set the desired flow temperature (typically 60-80°C). Use a room thermostat for more precise control.

What should I do if I smell gas?

Immediately turn off the gas supply at the meter, open windows and doors, do not operate electrical switches, and call the National Gas Emergency Service (0800 111 999 in UK). Leave the building.

For your safety, we recommend that:

- You fully read and understand the information detailed in this manual before handling the pellet-run boiler, which is a biomass heating unit.

- You make sure the hydraulic circuit was correctly assembled and connected to the water supply before turning on the pellet-run boiler.

- The boiler is not intended for use by children or persons with limited physical, sensory or mental capabilities, nor by those lacking experience and knowledge, unless under direct supervision or instruction.

- Do not touch the boiler when barefoot, nor when any part of your body is wet or humid.

- Do not tamper with safety or adjustment features without the manufacturer's authorization;

- Do not cover or reduce the size of the vents at the installation area;

- The pellet-run boiler requires good air supply to guarantee correct combustion; as such, if the unit is kept in an air tight environment or is exposed to other existing sources of air extraction, its correct functioning may be impeded.

- The existence of vents is a requisite for proper combustion;

- Do not leave the packing materials near children;

- When the unit is operating normally, the boiler door cannot be opened.

- Avoid direct contact with parts of the unit that tend to become hot during operation;

- Check the existence of any obstructions on the fume duct before turning on the unit after a long period of inactivity;

- This pellet-run boiler is intended for residential use, within a protected environment. Safety systems may intervene to shut down the boiler. If this occurs,

contact technical assistance. In any circumstances should you attempt to interfere with the safety systems;

• The pellet-run boiler is a biomass heating unit equipped with an electric fume extractor. The occurrence of any power failure during its use may prevent fume extraction and the room will be filled with smoke. For this reason, you should have a natural fume extraction system, like a chimney, available;
• Solzaima offers an optional safety system that allows you to connect your boiler to a UPS unit, thus avoiding problems related to a power failure and ensuring that the fume extractor will continue to operate under such conditions until the complete extraction of all fumes;
• If you intend to use your boiler when leaving it unattended or while you are away from home, it is advised that you utilise the safety system specified above to guarantee its safe functioning in the eventuality of a power failure;

• While in operation, NEVER disconnect the electric plug of your pellet-run boiler. Seeing as the boiler's fume extractor is power-operated, disconnecting the plug would prevent the extraction of combustion fumes;

• Your unit must be disconnected from the mains for servicing. Before doing this, the unit must be totally cooled down (if operating before);

• Never touch the interior of the boiler without first disconnecting it from the power mains;
• The maximum water temperature (set-point temperature) that the user can set for the boiler is 80°C. In the event of the boiler reaching a temperature of 95°C, it will automatically switch off and activate a corresponding alarm.

Figure 3 – Adjustable feet

• Remove the instruction manual from the package and hand it over to the client.
• Connect a 100 mm diameter pipe between the boiler's combustion gases output and the fume extraction pipe leading out of the building (e.g. through the chimney) – please check diagrams in point 4.
• If a tube is used for combustion air inlet from the outside, it shall be no longer than 60cm horizontally or present offsets (such as bends);
• Carry out the hydraulic installation (please consult point 4.5)
• Connectthe 230 VAC power cable to an grounded socket.
• The unit's remote control has a programmable thermostat. Optionally, a conventional external programmer may be used (not included) to automatically define the unit's operating periods.

3.1 Installation requirements

The minimum distance required between the pellet-run boiler and any highly flammable surfaces is found specified in 4.

The top of the boiler must be at a distance of at least 100 cms from the ceiling, especially in rooms with ceilings composed of flammable materials.

The base supporting the boiler cannot be of flammable material. As such, adequate protection should always be used.

Figure 4 – Minimum distances from all surfaces: a) upper view of the unit's installation; b) side view of the unit's installation

Warning!

Keep combustible and flammable materials at a safe distance.

4.2. Installation of pipes and fume exhaust systems:

• The exhaust pipe must have been designed for this purpose, in compliance to the location requirements and in accordance with any applicable regulations.
• Important! An inspection-"T", fitted with a hermetic lid, must be attached to the end of the boiler's exhaust pipe to allow for the regular inspection of the system, as well as the discharge of heavy dust and condensates.
• As indicated in Figure 4, the exhaust duct must be assembled so as to permit its cleaning and maintenance through the inspection points.
• Under normal operating conditions, the combustion gas flow should create a draught of 12 Pa one meter above the chimney neck.
• The boiler must not share the chimney with any other equipment.
• The pipes located outside the boiler's working area must have an internal diameter of 100 mm and be of double stainless steel insulation.
• The fume exhaust pipe may generate condensation, so we recommend that the appropriate systems for collecting condensates should be installed.

4.3. Installation without a shaft

Figure 5 and 6 illustrate the basic requirements when installing the boiler's chimney. A "T" should be included at the base of the piping system for the purpose of periodic inspections and annual maintenance, as exemplified. Double-walled stainless steel insulated pipes must be used and properly fastened to avoid condensation.

Figure 5 – Side view of the boiler installation without a shaft, highlighting the inspection point.

c)
Figure 6 – Examples of standard installations.

⚠️ Failure to comply with the requirements here detailed may prevent the correct operation of the unit. Follow all the instructions presented on the diagrams.

The boilers operate with the combustion chamber in depression, which is why it is absolutely necessary that they include a fume exhaust pipe to adequately extract combustion gases.

Fume duct material: The tubing must consist of 0.5 mm thick rigid stainless steel, with fastening joints attaching the different sections and accessories.

Insulation: The fume ducts must be double-walled and insulated to make sure that fumes do not cool down going outwards, which would cause an inadequate circulation and condensation that may damage the unit.

Output "T-tube": Always attach a regulator "T-tube" to the output of the boiler.

Windproof terminal: A windproof terminal must always be installed to avoid the backflow of fumes.

Chimney draught: The figures below show three standard diagrams, specifying adequate lengths and diameters. Any other type of installation must guarantee a draught of 12 Pa (0.12mbars) measured when hot and at the maximum power.

Ventilation: To ensure the boiler's optimum operation, the installation location should be fitted with an air vent, with a minimum cross-section of 100 cm preferably close to the unit's back panel. The boiler includes a circular pipe (∅ 50mm) that may be routed to the exterior of the house.

4.4. Installation with a shaft

As shown in Figure 7, the pellet-run boiler is installed with a ∅ 100 mm exhaust pipe directed up the chimney. If the chimney is too large, an 80 mm-wide pipe should be installed at the fume outlet.

A "T"-tube must be attached to the base of the piping to allow for periodic inspections and annual maintenance, as illustrated in Figure 7.

Figure 7 – Side view of the boiler installation with a shaft, highlighting the inspection point.

It is recommended that the boiler not be used during adverse weather conditions that may seriously disrupt the unit's fume extraction capacity (this is especially the case with very strong winds).

If you do not use the unit for a long time, check it to make sure that the flue pipes are clear before lighting the fire.

4.5. Hydraulic Installation

* Chapter 12 (installation diagrams) includes diagrams illustrating the range of possible connections that may be used in the installation of a central heating system, with or without the feature of heating water for domestic use;

* The pellet-run boiler comes equipped with a circulating pump, an expansion tank

(with a volume of 10 litres, in the case of the 18kW model, and of 16 litres, in the case of the 24kW and 30kW models) with a pre-charge pressure of 1.0 bar, as well as a 3 bar safety valve;

* Operating pressure is between 1 and 1.5 bars;

* To empty the unit, attach a "T-tube" with a tap to the outlet (connected to the household sewage); the safety valve (3 bar) outlet must also be connected to the household sewage;

* The heat transporting fluid must consist of water mixed with an anti-corrosion, non-toxic product added in the quantity recommended by the manufacturer. If there exists any risk of freezing in the space where the boiler is installed, or within its fluid pipes, the installation engineer must add the manufacturer's recommended quantity of anti-freeze agent to the circulating fluid, in order to avoid freezing at the absolute minimum expected temperature.

4.6. Operating mode for radiator/Buffer tank

IMPORTANT! The boiler is programmed to work directly for radiators, in case you want to install the boiler with a buffer or AQS tank, we recommend changing the temperature "OFF" of the circulation pump by placing the same temperature as the deposit or 1 °C higher than this temperature, should disable the "hYDRO Menu" modes "Modulating Pump" and "hydro independent" and switch the mode display "Auto" to "Manual" mode and select the power 5 (Fire 5).

You must change the smoke temperatures ("Toff" and "Ton") in the "Activation" menu. For these changes is necessary to access the "Installer Menu" on the display, please request a password manufactures.

5. Fuel

The boiler must be exclusively fuelled by pellets. No other fuel may be used. Use only pellets certified by standard EN 14961-2 grade A1, 6mm in diameter and a length between 10-30mm.

The pellets may have a maximum humidity of 8% their weight. To guarantee a good combustion, the pellets must maintain these characteristics so they should be stored in a dry place.

The use of pellets of varied quality reduces the boiler's efficiency and leads to an inadequate combustion process.

You should always use certified pellets and must not forget to test a sample before buying large bulks.

The physical/chemical properties of the pellets (calibre, friction, density and chemical composition) may vary within specific tolerances and according to each manufacturer. Please note that this may cause alterations to the feeding process and, consequently, the need for different doses (more or less pellets).

The boiler's pellet dosage can be adjusted during the start-up phase and at the power thresholds of ± 25% (see the manual - temporary and power settings)

Warning!

The unit must NOT be used as an incinerator.

6. Use of the pellet-run boiler

Recommendations

Before starting up the unit, please check the following:

- Guarantee that the boiler is properly connected to the power mains by means of the 230 VAC power cable.

Close-up of a metallic electrical plug with a cable inserted, showing no visible text or symbols

Figure 8 – Electric power plug.

• Check to see whether the pellet reservoir is supplied with pellets. Inside the pellet reservoir is a safety grid to prevent users from reaching theworm screw.
  • Always check whether the burner is unblocked before igniting the boiler.

The boiler's combustion chamber, as well as its doors, are made of iron plate painted with high temperature resistant paint. Fumes are released during the initial burning sessions due to the curing of this paint.

Avoid touching the unit during its first burn to prevent leaving permanent marks on the paint. The paint goes through a more plastic phase during the curing process. The curing of the paint occurs at approximately 300^irc C and for 30 minutes.

Ensure that the hydraulic circuit was correctly assembled and is connected to the water supply;

You should check that there is sufficient ventilation in the room where the unit is installed, otherwise it will not work properly. You should therefore check to see whether there are other heating air-consuming units in the room (e.g. gas units, oil boilers, etc.), which should not be used simultaneously with the unit.

The pellet-run boiler is equipped with a sensor probe for measuring room temperature. This probe is attached to the grid located on the back panel of the unit (Figure 9). For a good reading of the room temperature, avoid the contact between the end of the probe and the unit chassis. You may also attach the probe to the wall beside the unit.

9. Installation of the external silo

Solzaima's automatic wood pellet boiler has an internal tank with a capacity of 45kg of wood pellets. Solzaima's optional storage unit allows you to increase by about 200kg the amount of wood pellets available, significantly increasing the autonomy of the boiler.

The optional storage unit set includes:

- Storage unit;

- Casters for moving the storage unit;

- Worm drive channel to transport the pellets into the boiler's internal tank;

- Electric power engineer to rotate the worm drive screw;

- Circuit board with wiring included;

- pellet level sensor of the storage unit

Together with the storage unit a connection kit to the boiler is provided and it includes:

• Instruction manual;
• Storage unit instruction manual;
• Flexible hose with metal bracket to connect the storage unit to the boiler;
• Cable to connect the storage unit level sensor and Pellet level sensors for the

boiler's internal tank to the circuit board;

- Cable for electrical connection of the deposit;

- Ramp to put inside the boiler's tank;

- Parts for the rear and lateral fixation of the storage unit to the boiler;

- Screws for attaching the level sensors to the tank of the boiler.

Description of operation

When the level sensors of the boiler's internal tank ceases to detect pellets (the sensor lights go off) the electric power engine of the storage unit is triggered, by rotating the worm drive screw of the storage unit. Thus the pellets are transported from the storage unit to the boiler's internal tank. The electric power engine will run continuously until the sensors in the boiler's tank detect pellets again (sensor lights turn on). When this happens, the electric power engine stops.

Thus, the storage unit system will be triggered each time the pellets level in the boiler's tank is low, preventing the boiler's flame is extinguished due to the lack of pellets.

In the storage unit, there is also a sensor that detects the level of pellets. When the pellets level is low, the sensor will cease to detect the pellets (the sensor light

goes off) and will appear on the display a message of troubleshooting. After 40 seconds will appear on the boiler's display na alarm signal (code A15) and the boiler shuts down. The electric power engine keeps running, fueling the boiler's internal tank until the sensors detect pellets.

To restart the boiler, you will have to refill the storage unit with pellets (at least until the level sensor detects pellets) and reset the error (see automatic boiler instruction manual).

The wood pellet storage unit can be installed on either the left or right side of the boiler. By default, it is configured to be installed on the right side of the boiler.

For greater ease you should proceed to the assembly and adjustment of the storage unit before installing the boiler.

Adjusting the height of the boiler

With the boiler placed in its final position, and before starting the installation of the storage unit, you should level the boiler and put it at the same height of the storage unit. To do so, you should place the storage unit beside the boiler (left or right) and adjust the leveling feet of this until it is aligned with the storage unit by the upper zone, as shown in the following pictures.

Figure 21 – Adjusting the height of the boiler

Adjusting the sensor's response time and sensitivity

You can adjust the pellet level sensor's sensitivity. The higher the sensitivity, the better the sensors will detect the pellets in their proximity to send an electric signal to the control circuit board.

2 – Next, you should remove the storage unit's level sensor. By default, it comes installed on the left side of the storage unit (the storage unit is set up by default to be installed on the right side of the boiler). To do this, loosen the screws of the part that supports the sensor and remove the set.

Figure 28 – Adjustment of the sensors sensitivity

- If the light do not go out when moving the sensor away from the pellets or do not come on when approaching, re-adjust the sensitivity of the sensor and repeat the test.

- You shall perform the sensitivity adjustment for both the boiler's tank level sensors and for the storage unit's level sensor.

You can also adjust the sensor's response time, to set the time the sensor waits before sending the signal to the circuit board upon detecting the pellets. This setting can be made directly on the storage unit electronic circuit board, on the upper right corner, using the same procedure used for adjusting the sensitivity – rotate clockwise to increase the response time and counter clockwise to decrease the response time.

The response time should be set to the minimum value

Installing the storage unit on the right side of the boiler

The level sensor of the storage unit must always be installed on the side closest to the boiler.

1 – If you want to install the storage unit on the right side of the boiler you must install the level sensor on the left side of the storage unit, in the same place where he comes assembled by default. Before, you should disconnect the plug of the cable connected to the circuit board, to facilitate the assembly. To fasten it, you should use the screws previously removed, and put it in the position shown in Figura 29-b.

Enabling the pellet level sensor

At the end of the storage unit's installation it is necessary to activate the pellet level sensor in the boiler's display. For this, you should enter the technical menu. (Password only provided to authorized technical personnel)

Within this menu, you should enter the General Settings, and in the Pellet Level Sensor menu you should press Set, and then the keys "+" and "-" until it shows On on the display.

When the storage unit runs out of pellets, the level sensor sends a signal and an alarm appears in the boiler's display (A15 code). You should refill the storage unit with pellets, reset the alarm and restart the boiler.

Boiler startup

With the storage unit properly fixed to the boiler (right or left side) you should carry out the hydraulic connections and the connection of the boiler to the fumes outlet. After making the connections, you should introduce some pellets inside the storage unit and start the operation of the boiler. You must observe the pellets falling from the storage unit to the boiler's internal tank and check if the level sensors work properly.

If the sensors do not work properly, you should remove them and re--adjust the sensitivity.

You must observe the boiler working for a time period corresponding to 3 or 4 charges of pellets and check if the pellet level does not rise above the level of the sensors.

10. Maintenance

Additional cleaning

Additional cleaning should be carried out for every 2000 Kg of pellets consumed. The boiler's air pipes and respective turbulators must be cleaned. To do this, start by opening the lid located on the top of the unit (Figura 57-a) and removing the six butterfly nuts securing the lower lid (Figura 57-b e c). Next, pull up the turbulators (Figure 57-d), also removing the spring support (Figure 57-f). A vacuum cleaner should be used to clean this area and the interior of the pipes may be cleaned using a steel brush (Figure 57-g) The turbulators and springs previously removed should also be cleaned with a steel brush.

To reinstall the turbulators, execute in reverse the above procedure shown in the figures.

Note:

- The chrono-thermostat Earth leakage must have a hysterisis of 15 to 25 °C. ①

- Hydro independiente "Off" (water temperature controlled regulation), put the boiler in "manual" mode and power nivle to "5"

- Modulating pump "On"

- Water sensing inhibition "On"

- Alternative hydro shutdown "On"

- Pump "On" = 50 °C

- Pump "Off" = same or thermostat temperature 1 °C below the temperature differential thermostat

When using the generator with differential thermostat the machine must be connected in the CONNECTION "Remote".

Calculation deposits of inertia: the boilers for pellets is recommended that the buffer tank has 20l/kW.

19. Life cycle of a pellet-run boiler

About 90% of the materials used in the manufacture of these units are recyclable, thus contributing towards a reduced environmental impact and the sustainable development of our planet. As such, units that have reached their end of useful life should be delivered to authorised waste operators. It is advised to contact your local authorities for the appropriate collection instructions.

20. Glossary

Ampere (A): SI unit of measurement of electric current

bar: unit of pressure equal to exactly 100,000 Pa. This pressure is very close to standard atmospheric pressure.

cal(Calorie): equal to the amount of heat required to increase the temperature of one gram of water by one degree centigrade.

cm (centimetres): unit of measurement.

CO (carbon monoxide): Lightly flammable, colourless, odourless and very dangerous gas, due to its toxicity.

CO₂ (carbon dioxide): Gas needed by plants for photosynthesis on the one hand, and emitted into the atmosphere on the other, contributing to the greenhouse effect.

Combustion: a process for obtaining energy. Combustion is basically a chemical reaction that requires three items in order to take place: fuel, oxidant and ignition temperature.

Oxidiser: chemical substance used for combustion (essentially oxygen) which is required for it to take place.

Combustible: anything that can undergo combustion, in this case referring to wood.

Creosote: chemical compound created by combustion. This compound is sometimes deposited on the glass and shaft of the heating recovery unit.

Circuit breaker: Electromechanical device that protects a given electrical appliance.

Energy Efficiency: capacity to generate large quantities of heat with the least amount of energy possible, causing the least environmental impact and reducing the energy budget.

CO Emissions: emission of carbon monoxide gas into the atmosphere.

CO emissions (13% of O₂ ): carbon monoxide content corrected to 13% of O₂ .

Differential Switch: protects people and property against grounding failures, preventing electric shocks and fires.

kcal (Kilocalorie): multiple unit of measurement of calories. Equivalent to 1000 calories.

kW (Kilowatt): Unit of measurement equal to 1000 watts.

mm (millimetres): unit of measurement.

mA (milliampere): unit of measurement of electric current.

Pa (Pascal): standard IS unit of pressure and tension. This unit is named after Blaise Pascal, an eminent French mathematician, physicist and philosopher.

Net Heating Value: also known as specific combustion heat. It represents the amount of heat released when a certain amount of fuel is completely burned. Net heating value is expressed in calories (or kilocalories) per unit of weight of fuel.

Rated power: Electrical power consumed from the energy source. Measured in watts.

Rated net heating value: heating capacity, i.e. the heat energy the unit transfers from energy present in the firewood – measured for a standard load of firewood over a given period of time.

Power output: a manufacturer's recommendation from tests on the equipment with firewood loads within a reasonable operating range. This power output range will present different firewood consumptions per hour.

Plumb: vertically above the installation.

Performance: expressed as a percentage of “useful energy” that can be extracted from a given system, taking into account the “total energy” of the fuel used.

Ignition temperature: temperature above which the fuel can enter into combustion.

Thermoresistant: resistant to high temperatures and thermal shock.

Glass ceramics: highly resistant ceramic material produced through controlled crystallisation of vitreous materials. Used widely in industry.

W(Watt): IS unit of power.
