TROUBLESHOOTING GUIDE
Fan fails to start
Check wall switch is turned ON
Check the light on the control box illuminates when ON switch is pressed. If no light,
check fuse.
Turn OFF the wall switch, check all plugs and connectors from fire to fan and fully and
correctly fitted. If all connections are correct, suspect faulty wiring loom or control
box.
Fan runs but cycles from high to low.
Check fan outlet for obstruction
Check all connections are fully and correctly fitted.
Ensure silicone sensing pipes and properly fitted to sensing tubes.
The terminal must only be fitted with the outlet facing downward.
This appliance is only for use with 230V~50Hz, being the standard UK domestic
supply.
Fan cycles high to low on windy days
This is quite normal on windy days
If this occurs on still days then the pressure switch may be over sensitive. Consult the
manufacturer before attempting any adjustment.
In exposed areas a small deflector plate may be fitted to the terminal guard cage to
reduce the effects of prevailing winds.
Fan runs in correct sequence but will
Check test conforms to manufacturers instructions
not pass spillage tests.
Check for blockages or leaks in flue or fan outlet.
Check gas type and pressure are correct for appliance.
Check for adequate ventilation or the effect of extractor fans.
Fan runs but pilot flame will not hold
Loose thermocouple connection in rear of gas valve
when control knob is released
Check pilot flame is engulfing tip of thermocouple.
Pilot will not light
Check gas is turned ON and all pipes are purged of air.
Check for spark between pilot body and electrode. Check spark gap is correct to
specification. Check the HT lead is connected to pilot body.
Check gas line and filters for blockages.
Check to see if pilot can be lit with match or taper whilst depressing control knob.
Safety solenoid may not be opening. Listen for click after starting fan.
Pilot shrinks when fire is turned to high
Sign of insufficient gas pressure causing pilot starvation. Check appliance pressure at
test point.
Ensure restrictor elbow is fully open.
Suspect undersized or partially blocked supply pipes.
Check none of the fittings are causing restriction. Excess solder and flux can obstruct
pipes.
Fan or fire cuts off when getting hot
Check for blockages in flue outlet which could cause thermal trip to operate.
Check for pilot shrinkage due to low gas pressure.
Fan constantly runs at high speed.
Check connection from wiring loom to pressure switch are fitted correctly.
Under normal conditions the fan should only run for a few moments at high speed
before the pressure switch detects airflow, dropping the fan down to normal speed.
Consult the manufacturers before attempting any adjustment of the pressure switch
