13 Fault Finding

Before detailed checking of electrical components ensure that remote controls are calling for

heat. Check that the gas supply is free of obstructions and purged of air. Check the overheat

thermostat and fluehood thermostat have not operated. Isolate the electrical supply and

physically check ALL cables, connections and the printed circuit board (PCB) fuse. Check

 

the air tubes to air pressure switch.
