12.0Commissioning the Boiler
12.1Commissioning the Boiler
WARNING: The PCB Control and Fan Assembly are 325 Vdc. Isolate at supply before access.
1.Reference should be made to BS:EN 12828 & 14336 when commissioning the boiler.
2.At the time of commissioning, complete all relevant sections of the Benchmark Checklist at the rear of this publications.
3.Flush the whole system using a suitable flushing agent (see Section 6.2) and vent the radiators. Check for water leaks.
4.Refill the system with inhibitor following the inhibitor manufacturer’s instructions and BS 7593 Code of Practice for Treatment of Water in Domestic Hot Water Central Heating Systems (see Section 6.2).
5.Complete the label supplied with the inhibitor and attach to the inside of the boiler case. Detail of system treatment should be added for future reference.
6.Turn the gas supply on and purge according to in GB BS 6891 and in IE I.S. 813 “Domestic Gas Installations”.
7.Turn the gas service cock anticlockwise to the ON position and check for gas tightness up to the gas valve (Fig. 34). Turn the power to the boiler ON.
IMPORTANT: The combustion for this appliance has been checked, adjusted and preset at the factory for operation on the gas type specified on the appliance data plate. No measurement of the combustion is necessary. Do not adjust the air/gas ratio valve.
8. Having checked:
•That the boiler has been installed in accordance with these instructions.
•The integrity of the flue system and the flue seals.

Turn the Central Heating Control Knob clockwise to increase or anticlockwise to decrease the boiler flow temperature.
The Reset Button should extinguish the Flame Failure Light and restore normal operation.
This indicates that there is electricity to the Boiler.
This indicates that the Burner has fired up and is heating your system.
If Flame Failure Light is ON. Press the Reset Button. If Flame Failure occurs persistently consult your Installer or Service Engineer.
•The integrity of the boiler combustion circuit and the relevant seals.
Proceed to put the boiler into operation as follows:

| Priming the Condensate Pump |
1. Using a funnel and tube, carefully pour approximately 1litre of | |||
tap water into the flue products exhaust at the terminal or flue | |||
elbow sampling point to fill the trap and allow the condensate | |||
pump reservoir to fill. | |||
2. Continue filling with water until the condensate pump | |||
operates. |
|
Condensate Pump This indicates that the Condensate Pump is running.
The pump ONLY runs when the condensate reservoir is full.

3. | Check that the condensate drain pipework is not leaking and |
that it is discharging correctly to drain. | |
4. | See Fig. 36a for operation of LEDs on boiler facia. |
