Frequently Asked Questions - Estelle HE B4 INOX ErP SIME

How to start the SIME Estelle HE B4 INOX ErP boiler?

Make sure the system is filled with water and purged. Open the shut-off valves. Switch on the boiler using the main switch (1). The green indicator lights up. Set the tank aquastat (7) to the desired temperature. The burner starts automatically. For heating, set the summer/winter switch (2) to WINTER position and adjust the boiler aquastat (8) to at least 60°C to avoid condensation.

What to do if the boiler does not produce domestic hot water?

Check that the summer/winter switch is in the correct position. Ensure the tank charging pump is working. Purge air from the coil by temporarily opening the non-return valve (horizontal notch) then return it to normal position. Check the tank aquastat setting (temperature between 30 and 60°C). If the problem persists, contact a technician.

How to purge air from the circulation pump?

On the tank pump, press and hold (3 seconds) the button (4) to activate the automatic purge function. The pump will perform the purge. Check that the hydraulic system is correctly supplied.

What does the orange indicator light on the control panel mean?

The orange indicator indicates insufficient water pressure in the system (pressure switch activation). Restore pressure between 1 and 1.2 bar using the filling valve. Monitor the hydrometer mounted on the heating pipe.

How to reset the safety aquastat?

If the temperature exceeds 95°C, the safety aquastat (4) trips and cuts off the burner. To reset, unscrew the black cap and press the small button underneath. If tripping is frequent, have the appliance checked by a technician.

How often should the boiler be serviced?

An annual service by an approved technician is mandatory. It includes cleaning the flue gas side (turbulators, exhaust pipe), checking the magnesium anode of the tank, inspecting the burner and safety devices. In case of frost, completely drain the system if the room is not heated.

How to clean the flue gas side of the boiler?

Cut off the power supply. Remove the door screws, take out the turbulators. Use a special brush to carefully clean the interior surface and the flue exhaust pipe. Reassemble the turbulators in their initial position.

What type of burner is compatible with this boiler?

The burner must be with continuous feed, with a semi-empty nozzle. The recommended model is the SIME FUEL35 EV (nozzle 0.65, angle 60°H, pump pressure 12 bar). Only use burners compliant with EN 267 suitable for the boiler output.

How to drain the boiler in case of frost risk?

Close the fuel and water valves. Open the drain valves of the boiler (S) and the tank (9). For a complete drain, also empty the contents of the tank and the tank heating coil. Ensure the system is protected with antifreeze if necessary.

What to do in case of burner or pump lockout?

For the burner, press the reset button if the lockout indicator is on. If the pump is locked (fixed red LED), activate manual restart by holding the button (4) pressed for 5 seconds. If the problem persists, replace the pump or contact a technician.

2 INSTALLATION

2.1 BOILER ROOM

The boiler room should feature all the characteristics required by standards governing liquid fuel heating systems.

2.2 BOILER ROOM DIMENSIONS

Position the boiler body on the foundation bed, which should be at least 10 cm high. The body should rest on a surface allowing shifting, possibly by means of sheet metal. Leave a clearance between the boiler and the wall of at least 0.60 m, and between the top of the casing and the ceiling of 1 m (0.50 m in the case of boilers with incorporated D.H.W. tank). The ceiling height of the boiler room should be less than 2.5 m.

2.3 CONNECTING UP SYSTEM

When connecting up the water supply to the boiler, make sure that the specifications given in fig. 1 are observed. All connecting unions should be easy to disconnect by means of tightening rings. A closed expansion tank system must be used.

ATTENTION: The installation of a by-pass or a flow switch (not supplied) is mandatory in the case of installations in systems with thermostatic valves or motorized two-way valves.

The minimum flow rate of the system, which must be guaranteed, must not be lower than that shown below.

Minimum system flow rate 850 (l/h) with T = 35^

2.3.1 Accessories (fig. 2)

To ensure boiler efficiency, and a pressure relief valve set to 3 bar/294 kPa (14) and a hydrometer to check the system pressure (16).

Install a pressure relief valve calibrated to 6 bar/588 kPa (7) on the boiler water outlet pipe to prevent the risk of bursting due to excess pressure build up. If the boiler safety valve cuts in frequently, install a 5-litre expansion vessel (15) with maximum operating pressure of 8 bar/784 kPa on the hot water circuit. The tank should be fitted with a natural rubber food-grade diaphragm. The central heating circuit pump (4) can be installed at the rear of the boiler in place of the connection union 1" pos. 3 fig. 4/a.

2.3.2 Filling the water system

Before connecting the boiler, thoroughly flush the system to eliminate scale which could damage the appliance.

Filling must be done slowly so as to allow any air bubbles to be bled off through the air valves.

In closed-circuit heating systems, the cold water filling pressure and the pre-charging pressure of the expansion vessel should be no less than or equal to the height of the water head of the installation (e.g. for water head of 5 meters, the vessel pre-charging pressure and installation filling pressure should be at least 0.5 bar).

During the preparation of hot water, the circulating pump installed on the boiler circuit remains in operation until the boiler thermostat probe detects the pre-selected value.

Once the boiler thermostat has reach the set point, and the selector has been set to winter operation with the room thermostat on demand, the central heating circuit pump (not supplied) can be actuated.

All residual air in the boiler coils must be bled at the first start-up to ensure proper operation.

To facilitate this operation, position the slot of the release screw on the check valve horizontally (6 fig. 2). Once the air has been bled, return the screw to its original position.

Hot water for sanitary use is prepared by the boiler in AISI 316L stainless steel, which is fitted with a special spiral-shaped stainless steel heat exchanger, a magnesium anode to protect the boiler and an inspection flange to simplify checking and cleaning.

2.3.4 Characteristics of feedwater

To prevent lime scale and damage to the tap water exchanger, the water supplied should have a hardness of no more than 20^ F.

In all cases the water used should be tested and adequate treatment devices should be installed.

To prevent lime scale or deposits on the primary exchanger, the water used to supply the heating circuit should must be treated in accordance with UNI-CTI 8065 standards. The water used for the central heating system should be treated in the following cases:

- For extensive systems (with high contents of water).

- Frequent addition of water into the system.

- Should it be necessary to empty the system either partially or totally.

2.4 CONNECTING UP FLUE

The flue is of fundamental importance for the proper operation of the boiler; if not installed in compliance with the standards, starting the boiler will be difficult and there will be a consequent formation of soot, condensation and encrustation.

A flue therefore must satisfy the following requirements:

- be constructed with waterproof materials and resistant to smoke

KEY 1 Drain hose 2 Condensate drain tap 1 2 Fig. 5

temperature and condensate;

• be of adequate mechanical resilience and of low heat conductivity;
• be perfectly sealed to prevent cooling of the flue itself;
• be as vertical as possible; the terminal section of the flue must be fitted with a static exhaust device that ensures constant and efficient extraction of products generated by combustion;
• have a diameter that is not inferior to that of the boiler union;
• to be properly sized to meet the flue gas draught/exhaust requirements necessary for regular operation of the product (EN13384-1);
• a specific condensate outlet system must be installed at the bottom of the flue;
• rigid pipes must be used for the connection to the flue, resistant to

high temperatures, condensation, mechanical stress, sealed and insulated. Use material suited to the purpose, such as stainless steel.

2.5 CONNECTION OF CONDENSATION

WATER TRAP (fig. 5)

The drip board and its water trap must be connected to a civil drain through a pipe ( 25) with a slope of at least 5 mm per metre to ensure drainage of condensation water.

The plastic pipes normally used for civil drains are the only type of pipe which is appropriate for conveying condensation to the building's sewer pipes.

2.6 ELECTRICAL CONNECTION (fig. 5/a)

The boiler is fitted with an electricity cable, and requires a single-phase power supply of 230V - 50Hz through the main switch protected by fuses. The room thermostat (required for enhanced room temperature control) should be installed as shown in fig. 5/a. Connect the burner and system circulation pump power cables supplied.

NOTE: Device must be connected to an efficient earthing system.

SI ME de cli nes all responsibility for injury caused to persons due to failure to earth the boiler.

Always turn off the power supply before doing any work on the electrical panel.

• The appliance can be used by children under 8 years and by persons with reduced physical, sensory or mental capabilities, or lack of experience or knowledge, provided they are under supervision or after they have been given instructions concerning the safe handling of the appliance and the understanding of the dangers inherent to it. Never let children play with the appliance. Children without supervision must not carry out cleaning and maintenance meant to be carried out by the user.

3.1 COMMISSIONING THE BOILER

When commissioning the boiler always make sure that:

• the system has been filled with water and adequately vented;
• the flow and return valves are fully open;
• the flue and chimney are free from obstructions;
• the electrical connections to the mains and the earthing are correct;
• no flammable liquids or materials are near the boiler;
• check that the circulating pump is not locked.

3.2.1 Lighting the boiler (fig. 6)

To light the boiler proceed as follows:

- switch on the main switch (1); the green light turns on to indicate that the appliance is powered (3). The burner will start;

- set the stat knob (7) to the desired D.H.W. temperature.

The boiler pump will continue operating until the preset temperature has been reached.

While the water is being heated, the boiler will continue automatic operation to maintain the heat-

ing temperature shown on the thermometer (5) around 80°C by means of the limit stat (6);

- once the water has been heated with the selector (2) set to the summer function position, the burner and the circulating pump will cease operation; when the selector (2) is set to the winter position, the system pump controlled by the room stat will start up.

In this case, operation of the burn-er will be controlled by the boiler

stat (8) at the preset temperature;

- for best results, set the boiler stat knob (8) to a temperature no lower than 60^ to prevent the formation of condensate.

The set temperature value can be checked on the thermometer (5).

3.2.2 Safety stat (fig. 6)

The manually reset safety stat (4) trips to switch-off the burners immediately when the boiler tem-

perature exceeds 95°C.

To restart the boiler, unscrew the black cover and press the button underneath.

If the problem occurs frequently, call an authorised technical assistance centre for the necessary checks to be carried out.

3.2.3 System filling (fig. 6)

If the orange LED (9) switches on due to the enabling of the water pressure switch and stops the boiler, it is possible to restart it by resetting the plant pressure to 1-1.2 bar (98-117.6 kPa). The system pressure is checked through the hydrometer mounted on the heating delivery tube (16 fig. 2).

3.2.4 Turning OFF boiler (fig. 6)

To turn off the boiler, cut off the voltage by pressing the mains switch (1). Close both the gas-feed pipe tap and the water tap if the boiler remains inoperative for a long period.

3.3 REGULAR CLEANING

Maintenance of the boiler should be carried out annually by an authorised service engineer.

Disconnect the boiler from the electrical supply before servicing or maintenance is carried out.

3.3.1 Smoke side boiler (fig. 7)

To carry out cleaning of the smoke passages remove the screws that fix the door to the body of the boiler and with the special cleaning brush clean the internal surfaces and the smoke evacuation tube well, removing any deposits. Once the maintenance is compiled, the baffles have to be fitted onto the original positions.

3.3.2 Tank unit protection anode (fig. 8)

Check the magnesium anode periodically; replace when exhausted. Failure to renew exhausted anodes will render

Technical line drawing of a multi-tiered industrial machine with open lid and internal components (no text or symbols)

the guarantee null and void.

To access the anode, remove the inspection flange that enables the boiler to be checked and cleaned.

3.3.3 Dismantling the skirt (fig. 9)

The shell can be completely disassembled for an easy maintenance of the boiler by following the numeric steps shown in fig. 9.

3.3.4 Fault finding

Herefater we outline a number of potential problems that may occur on the appliance and the relevant list of actions required.

A working fault, in most cases, provocates the "lock out" signal onto the control panel of the control box. When this light turns on, the burner can operate again only after the reset button has been pressed; if this has been done and a regular ignition occurs, it means the failure can be defined momentary and not dangerous. On the contrary, if the "lock out" stays, the cause of the fault, as well as the relevant action must be made according to the following chart:

The burner does not ignite

• Check the electric connections.
• Check the regular fuel flow, the cleanness of the filters, of the nozzle and air vent from the tube.
• Check the regular spark ignition and the proper function of the burner.

The burner ignites regularly but the flame goes out immediately

- Check the flame detection, the air calibration and the function of the appliance.

Difficulty in regulating the burner and/or lack of yield

- Check: the regular flow of fuel, the

cleanness of the boiler, the non obstruction of the smoke duct, the real input supplied by the burner and its cleanness (dust).

The boiler gets dirty easily

- Check the burner regulator (smoke analysis), the fuel quantity, the flue obstruction and the cleanness of the air duct of the burner (dust).

The boiler does not heat up

- Control the cleanness of the shell, the matching, the adjustment, the burner performances, the pre-adjusted temperature, the correct function and position of the regulation stat.

- Make sure that the boiler is sufficiently powerful for the appliance.

Smell of unburnt products

- Control the cleanness of the boiler shell and the flue, the airtightness of the boiler and of the flue ducts (door, combustion chamber,

Technical diagram of an open refrigerator internal structure with numbered components and a magnified inset showing internal components.

Fig. 9

smoke ducts, flue, washers).

- Control the quality of the fuel.

Frequent intervention of the boiler shutoff valve

- Control the presence of air in the system, the function of the circulation pumps.

- Check the load pressure of the appliance, the efficiency of the expansion tanks and the valve calibration.

3.4 ANTIFREEZE PROTECTION

In freezing weather, make sure that the heating system continues to function and that the rooms are kept warm enough, including the room in which the boiler is installed; if this cannot be done, both the boiler and the heating system must be completely emptied.

Completely emptying the system also means emptying the hot water tank and the hot water heating coil.

3.5 USER WARNINGS

It is mandatory that the dedicated power cable is replaced only with a spare cable ordered and connected by professionally qualified personnel.

ATTENTION: Before performing any work on the boiler, make sure that the same and its components have cooled in order to prevent the risk of burns due to high temperatures.

3.6 DISPOSAL OF THE EQUIPMENT (2012/19/UE)

Once it reaches the end of its operating life, the equipment MUST BE RECYCLED in line with current legislation. IT MUST NOT be disposed

of together with urban waste.

It can be handed over to recycling centres, if there are any, or to retailers that offer this service.

Recycling prevents potential damage to the environment and health. It allows to recover a number of recyclable materials, with considerable savings in terms of money and energy.

3.7 D.H.W. PUMP (fig. 10)

Press the button (4) briefly (about 1 second) to select the pump operating mode. The relative LEDs will indicate each time the adjustment mode (2) and the characteristic curves set (3).

Point 3.7.4 reports the possible combinations and their meaning.

When the LED (1) signals a fault, the pump stops and attempts to run re-start cycles. If the fault is solved, the pump restarts automatically.

3.7.1 Venting the pump

The pump venting function is activated by pressing the button (4) for a long time (3 seconds) and vents automatically.

3.7.2 Factory settings

The factory setting is activated by pressing and holding the button (4) and disabling the pump. When the pump is restarted, it will work with factory settings (delivery state).

3.7.3 Manual restart

When a lockout is detected, the pump tries to start automatically. If the pump does not restart, restart manually by pressing the button (4) for a long time (5 seconds), then release it. The restart function is activated for a maximum of 10 minutes. After the restart, the LED indication shows the previously set values.

If the fault persists, replace the pump.

Variable differential pressure p - v (I, II, III)

Recommended for two-pipe heating systems with radiators to reduce the flow noise at thermostatic valves.

The pump reduces the delivery head to half in the case of decreasing volume flow in the pipe network. Electrical energy saving by adjusting the delivery head to the volume flow requirement and lower flow rates. There are three pre-defined pump curves (I, II, III) to choose from.

Constant differential pressure p - c (I, II, III)

Recommended for underfloorheating for large-sized pipes or all applications without a variable pipe network curve (e.g. storage charge pumps), as well as single-pipe heating systems with radiators.

The control keeps the set delivery head constant irrespective of the pumped volume flow. There are three pre-defined pump curves (I, II, III) to choose from.

Recommended for systems with fixed system resistance requiring a constant volume flow.

The pump runs in three prescribed fixed speed stages (I, II, III).

Factory setting: Constant speed, pump curve III

3.7.5 Possible pump faults, causes and possible solutions

Colour of LED	Possible fault Cause Possible solution
Flashing red-green	Turbine operation	The hydraulic system of the pump is powered, but the pump has no mains voltage	- Check the mains voltage
	Idle operation Air in the pump		- Check that there are no leaks in the system
	Overload	The motor runs with difficulty. The number of revolutions is lower compared to normal operation	- Check the mains voltage- Check the system flow rate/pressure- Check the characteristics of the water in the system; remove debris from the system
Flashing red	Under/overvoltage	Supply voltage too low/high	- Check the mains voltage
	Excessive temperature	Excessive temperature inside the pump	- Check the water temperature level in relation to that of the ambient temperature- Check the mains voltage- Check the environmental operating conditions
	Short circuit	Motor current too high	- Check the mains voltage
Steady red	“Permanent lockout” stop	Rotor blocked	- Restart manually
			- REPLACE THE PUMP
		Circuit board and/or motor failure	- REPLACE THE PUMP
LED Off	Stopped	Electrical power failure	- Check the connection to the power supply
		Faulty LED	- Check to see if the pump can work
		Faulty circuit board	- REPLACE THE PUMP
