the right hand side of the plinth is depressed.
Ensure the electricity supply is turned ON and set any
external controls to the ON position.
Turn the boiler thermostat knob to MAX., and the boiler
will ignite.
Turn the cooker thermostat to H, and the cooker burner
will go to full rate.
Check for gas soundness of all leaks with leak detection
fluid.

Turn the thermostat knob to the required setting.
The boiler and pump should be run until the system is
hot. Check for water leaks, then flush the system with all
manual/automatic valves open. Upon refilling check the
system for leaks. When all the air has been removed from
the water circuit, the pump and radiators should be
balanced to achieve the correct temperature to drop
across the system.

customer's requirements.
SPILLAGE TEST
With cooker and boiler burners full on.
A spillage test must be carried out after 5 minutes, as
follows:
Light a smoke match and position into the draught
diverter as shown in Fig. 10A. If smoke does not spill
back into the room then the installation is satisfactory. If
smoke is drawn back into the room leave burners on for
further 10 minutes and check again.
WARNING: IF THE SMOKE SPILLS BACK INTO THE
ROOM, DISCONNECT THE APPLIANCE AND SEEK
EXPERT ADVICE.
