Applies to: Napoleon gas fireplaces (spill switch applies to natural-vent units)
Common causes of test: spill switch and wall switch/thermostat wiring

How to fix test: spill switch and wall switch/thermostat wiring: step by step
- Spill switch: disconnect all wires, meter on ohms across the two spade terminals; the manual says replace the switch if it reads 1 ohm or higher.
- Wall switch/thermostat: with switch leads on valve terminals 1 & 3 (top and bottom), disconnect the leads at the switch end and join them together.
- Turn the valve on - if the burner lights, the wiring is good and the switch is faulty.
- WARNING: a spill switch / vent safety switch may be bypassed only temporarily for testing - it is illegal to leave it bypassed. Restore before leaving.
