IMPORTANT

When carrying out commissioning of the boiler, you are highly recommended to perform the following checks: –

Make sure that there are no liquids or inflammable materials in the immediate vicinity of the boiler.

– Make sure that the electrical connections have been made correctly and the earth wire is connected to a

weel done earthing system. – Open the gas tap and check the soundness of the connections, including the burner. – Make sure that the boiler is set for operation for the type of gas supplied. – Check that the flue pipe for the outlet of the products of the combustion is unobstructed and has been properly

installed. – Make sure that any shutoff valves are open and dirt seperators are installed on the return water connection. – Make sure that the system is charged with water and is thoroughly vented. – Check that the circulation pump is not locked. – Purge the system, bleeding off the air present in the gas pipe by operating the pressure relief valve on the gas

valve inlet. –

The installer must provide the user with instruction in operation of the boiler and safety devices and hand over the

instruction booklet to the user.

4.1.5 WATER QUALITY AND TREATMENT

If the water might contain aluminium particles, this should be maximum 8,5 ppm. If there is any doubt of the water staying free of any kind of debris/contamination in the period after installing, one should install a plate heat exchanger to separate the boiler circuit from the heating circuit. To avoid to the maximum any presence of oxygen in the system, we recommend to prevent as much as possible air intake and water leakage during installation. Power flush the pipes and radiators thoroughly to remove all fluxes and debris before connecting the boiler to the central heating sy s t e m i n ac c o r d a n c e w i t h loc a l reg u la t i o n s .

Instructions for the installer

The manufacturer declines any liability for damage caused to the boiler by failure to install or inadequate installation of this filter. Before switch on the boiler, water must be circulate at least 2 hours for elimination the impurities from the system trough the micro impurity seperator. In the end of the operation, safety drain valve must be opened for removing the impurities. It is also possible to use plate heat exchangers according the system characteristics. In any case, micro impurity seperators must be used in the system in the boiler. Before installation, carefully wash all the pipes of the system to remove any residuals or impurities that could affect proper operation of the unit. Filter must also be installed on the system return piping to prevent impurities or sludge from the system clogging and damaging the boiler.

CAUTION:

Boiler damage due to corrosion.

NOTE:

Damage to the installation due to insufficient or improper cleaning and maintenance.

Inspect and clean the heating system as required once a year.

Carry out maintenance as required. Immediately remedy faults. This will avoid further damage to the system!

DO NOT treat the water with antifreeze.

Suitable chemicals and their use should be discussed with a specialist water treatment company prior to carrying out any work (environmental aspects, health aspects). The specification of the system and manufacturers recommendations must be taken into account, along with the age and condition of the system. New systems should be flushed thoroughly to regulations to remove all traces of flux, debris, grease and metal swarf generated during installation. Care to be taken with old systems to ensure any black metallic iron oxide sludge and other corrosive residues are removed, again by power flushing, ensuring that the system is drained completely from all low points. It is important to check the inhibitor concentration after installation, system modifications, filling the system and every service in accordance with these instructions. For the correct dosage and the suitability of inhibitors for use with our boilers and for further information on water treatment or system cleaning we advise direct contact with Gassero service.

The gas and water connections are located on the bottom of

the boiler whilst the air intake and flue outlet is located on the top of the boiler. The boiler is supplied as standard with pipework tails to allow connections facing downwards. For installation, servicing and inspection min. 600 mm in front of the boiler is required. If this free space is obtained by opening a door or removing a panel, the boiler may be installed for instance in a closed cupboard. For ease of installation we recommend clearances of 0.5 cm at the side so that the unit is easy to open, with a free space of 25 cm under the appliance and 25 cm above the appliance, as the minimum requirement.

4.1.4 CLEARENCES

The pH value of the water must fall within the following limits: 7 < pH < 9 in non-treated water. This pH value is achievable after steady conditions when after filling the mains network water ( pH around 7 ) inside the installation and the air elimination operation has been done.Treated water hardness must within limits 7 < pH < 8,5

The plumbing system must be cleaned using with suitable registered produts before starting the installation of the boiler. Neutral, non-acidic and non-alkali cleaners( SENTINEL X300, X400, FERNOX ) must be used for preventing the metal, plastic and rubber parts in the installation system. Please obey the instructions of the manufacturer, when using these type of cleaners.

Note: Rust particles and impurities in the heating system can caused problems.( overheating, un-efficient and noisy work) Problems and damages due to wrong installations and wrong plumbing systems is out of warranty.

4.1.6 WATER SIDE CONNECTION INSTRUCTIONS

The heating capacity of the unit must be previously established

current regulations. The system must be provided with all the components for correct and regular operation. In particular, provide for all the protection and safety devices prescribed by current regulations for the complete system.

We strongly recommend to install two ball valves under the boiler, so the boiler can be isolated from the heating system when needed.

4.1.7 EXPANSION VESSEL

W therefore its connection must be carried out by the qualified installer. The capacity of the expansion vessel must be chosen and installed to match the capacity of the central heating system and the static pressure. We suggest you install the expansion vessel in the return line of the central heating system. It can be combined with the drain valve for servicing.

4.1.8 SAFETY VALVE

Safety valve outlet must be connected to collection pipe to prevent water spurting onto the floor in case of overpressure in the heating circuit. Otherwise, if the discharge valve cuts in and floods the room, the boiler manufacturer cannot be held liable.

4.1.9 CONDENSATE DISCHARGE

The condensate drain is in the left side at the bottom of the boiler and has a 25mm hose discharge. Connect this flexible

condensate drain. Metal lines are not allowed. Blockage of this drain may cause damage to the boiler. The drain connection is correct when the condensate can be seen flowing away, e.g. using a funnel. Any damage that may occur is not covered by the warranty of the boiler. There should be an open connection between the condensate hose from the boiler, to the sewage system. An under pressure in the sewage system should never be able to suck on the boiler condensate drain hose. The condensate drain must be connected in accordance with current regulations.

Do not use the water system pipes to earth electrical appliances.

4.1.10 FROST PROTECTION

Wallcon series boiler has built-in frost protection, automatically activating the central heating pump when the boiler return

will shut down as soon as the return temperature has reached demanded point. The above-mentioned temperatures relates

boiler. This Frost Protection provision is for the boiler only and not for the all system.

4.1.11 DIRT SEPERATION

the return of the boiler is such a way that the boiler water is free

check weekly after installation to determine the strainer cleaning interval.

Instructions for the installer

including an air bleed valve so the strainer can be isolated from the heating circuit for servicing. Clean water is important, blocked heat exchangers do not fall under warranty. The filter should be installed when replacing boilers in existing systems. The manufacturer declines any liability for damage caused to the boiler by failure to install or inadequate installation of this filter. Before switch on the boiler, water must be circulate at least 2 hours for elimination the impurities from the system trough the micro impurity seperator. In the end of the operation, safety drain valve must be opened for removing the impurities. It is also possible to use plate heat exchangers according the system characteristics. In any case, micro impurity seperators must be used in the system in the boiler. Before installation, carefully wash all the pipes of the system to remove any residuals or impurities that could affect proper operation of the unit. Filter must also be installed on the system return piping to prevent impurities or sludge from the system clogging and damaging the boiler.

We advise to mount valves before and after the strainer

There is an automatic air vent mounted in the boiler to remove air from the water circuit. This automatic air vent is only for eliminate the air in the heat exchanger of the boiler. One or more

always be installed in the heating system to eliminate air trapped in the heating circuit.

4.1.13 PUMP

The W circulation pump with 3-position electric speed control. The pump is the single-phase type (230 V - 50 Hz). To ensure optimal boiler operation, in the case of new systems (single pipe and module) it is recommended to use the pump at maximum speed. The pump runs when heat is required. When heat is no longer required, the pump will continue to run for another 3 minutes before it stops. The 24-hour cycle starts as soon as the power supply to the boiler is activated.

All the wiring is connected to connectors that is fitted in a socket. The connectors can be taken from the sockets on the PCB without loosening the wiring. The connections are placed in the back of the display, and can be reach by removing the front panel of the boiler and the connector protection cover. For operation the boiler needs a power supply of 230VAC 50Hz with earth.Power supply must be removed when you are working on the boiler. Electrical wiring should be done according to national, local or other special standards. Electrical works must be done by a qualified service engineer that is skilled in electrical installation according to the standards.

1 - Respect the connection L (Line) - N (Neutral) and earth (ground) connections.

2 - Use wires with a cross-section greater than or equal to 1.5 mm , complete with pointed end terminals; 3 - Refer to the wiring diagrams in this manual for any operations on the electrical system; 4 - Connect the appliance to an effective earth system. 5 - Power supply and room thermostat cables must not run near hot surfaces (outlet pipes).

The manufacturer is not liable for any damage due to the failure to earth the appliance and to observe the information provided on the wiring diagrams.

4.6.3 OUTDOOR TEMPERATURE CONTROL ( OTC )

The heating curve generates the flow temperature setpoint, which is used to maintain a certain flow temperature level depending on the prevailing weather conditions. The heating curve can be adjusted in different ways, thus matching the heat output and the room temperature to individual needs. When the heating curve slope is raised, the flow temperature increases as the outside temperature drops. Or, in other words, if the room temperature is not correct at low outside temperatures but correct at higher outside temperatures, the heating curve slope must be readjusted.

Increasing the slope: Raises the flow temperature, especially when the outside temperature is low.

Decreasing the slope: Lowers the flow temperature, especially when the outside temperature is low.

IMPORTANT INFORMATION

The set heating curve is based on a room temperature setpoint of 20 °C. If this setpoint is changed, the heating curve adapts automatically to the new value.

Heating curve – heating curve slope

Outdoor temperature

Flow temperature

Parallel displacement of the heating curve is used to change the flow temperature evenly across the entire outside temperature range or, in other words, if the room temperature is always too high or too low, a readjustment must be made with parallel displacement. Adaption of the heating curve is used by the controller to automatically adapt the heating curve to the prevailing weather conditions. In that case, a readjustment of heating curve slope and parallel displacement is not required. It can only be switched on or off.

IMPORTANT INFORMATION

To provide this function, following must be observed:

• A room sensor must be connected

• The Room influence setting must be selected between 1 and 99

• No thermostatic radiator valves should be used in the reference room, where the room sensor is located (if installed, such valves must be fully opened and locked in that position)

The function is activated with parameter, provided a room sensor is used and the compensation variant is weather compensation with room influence. If the required flow temperature is exceeded or is not reached for more than 2 hours, no adaption is made for that day. With pump heating circuits, the boiler temperature is used in place of the flow temperature. Heating curve adaption readjusts the heating curve’s slope and the parallel displacement (heat gains). In Comfort mode (nominal operating level), the function integrates the room temperature control deviation and readjusts at midnight the parameters for calculating the heating curve, depending on the attenuated outside temperature and the learning sensitivity. During boost heating, the deviation of room temperature control is not taken into consideration. When readjusting the heating curve or the heat gains, the sensitivity is automatically set to the maximum. A certain minimum sensitivity is always maintained. If the attenuated outside temperature is below 4 °C, the heating curve slope is readjusted through the learning process. If the attenuated outside temperature lies between 4 °C and 12 °C, heating curve slope and parallel displacement are readjusted through learning. If the attenuated outside temperature exceeds 12 °C, the learning process is stopped. These basic values apply to a Comfort setpoint of 20 °C, heat gains of 0 K and a heating curve displacement of 0 K.

Maintenance

Generally, the normal service period is one year. Each year the boiler should be cleaned and checked according to the maintenance procedure and ınstructions. If there is any doubt whether the boiler will operate with the correct water or combustion air quality, it is advisable that a first check is done after half a year to determine future service period.

6 MAINTENANCE

6.1 GENERAL

WARNING: Damage to the installation due to insufficient or improper cleaning and maintenance.

Inspect and clean the heating system once a year.

Carry out maintenance as required. Immediately remedy

faults. This will avoid further damage to the system!

6.2 MAINTENANCE PROCEDURE

Inspection, maintenance and the replacement of parts should be done by Gassero technical service. Besides doing maintenance we advise to create a log chart belonging to each boiler on which at least the following should be written:

- Serial number of the boiler

- Maintenance date

- Responsible personnel of maintenance.

- Parts and/or settings changed during maintenance.

- Special remarks

- Important points in the future.

During maintenance the following points should be checked and/or parts must be inspected and maintained.

Before doing any work on the boiler:

- Switch off the power to the boiler by service switch or pull out plug from wall socket

- Close the gas valve

Customer comments

Comments and notes from the customer should be taken seriously and an effort should be made to find the cause of any problems.

Service history

Faults and working history can be read from boiler interface or with a computer in combination with the software and interface cable of the PCB.

Water leakage

The pressure of the installation must be higher than 0,8 bar, and maximum 6 bar. Find possible leaks in the system and have these fixed.

Flue gas leakage

The flue gas discharge and air intake piping need to be checked for gas leakage. Also check if the piping is properly mounted and not damaged. Inspect the top of the boiler housing for traces of water leakage or traces of water from the air vent, or leaking condensate from the flue gas piping.

Gas lines/-connections

The gas lines need to be checked for gas leakage. Also check if the piping is properly mounted and not damaged.

Un-assembling the Burner

Un-assembling the burner unit: Remove the 6 x M6 nuts and the electrode cables, and move the burner unit forward. Remove the plug of the fan cable from the fan when the burner has been pulled half-way from the heat exchanger. Dismantle the air gas mixing box on the intake side of the fan and check the blade wheel of the fan.

Insulation

The insulation of the heat exchanger (located on the rear wall inside in the heat exchanger) must be inspected. If this insulation disk shows any sign of damage or impairment it should be replaced with a new one. Also check if there are any signs of a too high condensate level (caused by a blocked siphon) that might have wetted the insulation several times. When these signs can be seen, the rear wall insulation should be replaced. Only use the burner door insulation that is supplied by the manufacturer. The same procedure must be applied on the insulation and gaskets fitted on the burner door.

Burner- and burner door gaskets

When these show any signs of damage they must be replaced.

Siphon

Dis-assemble the bottom cover siphon and clean it. Check if the siphon connection on the heat exchanger is not blocked, and clean if necessary. Check afterwards if the siphon functions properly. This can be done by pouring clean tap water in the furnace (when burner door is removed) so it will exit the heat exchanger through the siphon. Make sure the insulation is not wetted.

Heat exchanger/combustion room

Check if there is any debris/deposit in the heat exchanger. The heat exchanger coils can be cleaned by using a non metallic brush. Afterwards the loose particles may be removed with a vacuum cleaner and/or flushing with water. Check flow of water out of siphon, and clean siphon if necessary. Any cleaning of the combustion chamber with acid or alkali products is prohibited!

Gas/air ratio

Always check the gas/air ratio by checking the combustion figure CO on maximum and minimum input. If necessary adjust these

figures.

Pump

If the pump is becoming noisy (certainly when the pump has been working for more than five years) it is recommended to replace the pump as a precaution.

Burner

The burner can be cleaned using a soft (non metallic) brush. The dust can be removed with a vacuum cleaner or pressurized air. Check if the burner surface shows any signs of damage. If the burner surface is damaged (example: cracks in the surface) the burner must be replaced.

Page 33

Maintenance

Fan

If deposits have been building up on the fan blades, carefully clean the blades one by one with a soft brush until the material of the blades is visible again. Work consistently in cleaning the blades, and do not use too much force or else the fan may get out of balance and run irregularly.

Ignition / ionisation electrode

Check if the distances between the electrodes and between electrodes and burner are OK. If not try to bend the electrodes in the right position. The electrodes are working under high temperature. Therefore the electrodes become hard and are difficult to bend. When bending used electrodes there is a risk of breaking or tearing the electrode. Check if there are any tears/ cracks in the electrodes after bending them. If so then replace the electrode with a new one. Also change the electrode if any cracks can be seen in the ceramic electrode insulation. If the electrode is changed the gasket should also be replaced.

7,00 ( 0,2) mm

Burner

When defects are found that cannot be fixed by the service engineer, he has to inform the end user about the defects, and should advise the end user to have them fixed.

This should also be mentioned on the service report of the boiler. During maintenance gas, air, flue gas and condensate connections are loosened and remounted. Make sure all the components are mounted gas-/water tight before recommissioning the boiler.
