Making the Electrical Connections
Hinge down the electrical box to gain access to the electrical connections. Push in the tabs P (Fig 12) on either side of the
boiler and pivot the box forward.
Connect the main cable M to live, neutral and earth.
If using a room thermostat or other external control :
Undo the two retaining screws V , remove cover and remove cable clamp. J (right side) (Fig. 13)
Remove connector C from the PCB in the cover
Connect the external control cable in place of the link S on the multipin plug C
Reconnect multipin plug into the socket on the printed circuit board. Secure the cable using the cable clamp and
replace the cover.
Note: The connections should be made so that should the lead be pulled from its anchorage, the current carrying wires
become taut before the earth wire

Pre-commissioning
Ensure that the system has been adequately flushed.
Purge gas supply of air and test for soundness.
Carry out final electrical tests to ensure the correct polarity and
earthing continuity.
DHW
Open the main cold feed valve 40.
Open all hot taps to purge DHW system.
Check for water soundness.
Check flow rate at the bath tap is set correctly (see technical data).
Central Heating
Open flow and return valves on the boiler 37 and 41 (Fig. 14)
Open the automatic air vent 18 (Fig. 2)
Fill system and vent radiators.
Set system pressure and remove filling loop.
Check for leaks.
Manually check pump is free to turn.
Switch on electrical supply.
Press the Central Heating switch 29 (Fig. 3) to switch on heating
mode.
Press the +
key
32 (Fig. 3) to set heating temperature to maximum.
Allow pump to run for several minutes.
Isolate the electrical supply.
Drain boiler and check water filter for installation debris.
Replace filter and recharge system.
Lighting the Boiler
Inspect the entire gas supply for soudness, including the gas meter,
the gas installation should be in accordance wiith the relevant
standards, in GB this is BS 6891 and in IE this is the current edition
of I.S.813.
Connect gas pressure gauge to test point 39 (Fig. 14).
Turn on the gas supply and boiler gas tap 39 (Fig. 14).
Ensure electrical supply is on.
Ensure all external controls are calling for heat.
Press on Central Heating switch 29 (Fig. 3) to switch on heating
mode.
Press the +
key
32 (Fig. 3) to set heating temperature to maximum.
The boiler will light. Allow the boiler to heat system.
Check the inlet gas pressure (working pressure) while boiler is
operating in hot water mode.(Refer to technicaldata).
Check the operation of the boiler controls and safety devices.(see
separate servicing leaflet for details).Set the by pass (refer to the
paragraph bellow).
Re-flush the system to remove any dissolved oils and fluxes.
Recharge system pressure and introduce any water treatment as
required.
