- Connect the hot wire to the black wire. Connect the neutral wire to
the white wire.
- Remove blockage. In extremely cold conditions, ice buildup may occur
on the terminal and should be removed as required.
- Check pressure readings
- Outlet pressure can be checked by removing cap (A) and replacing
it with a 1/8" NPT barb fi tting. Next, place pressure gauge tubing
over the fi tting. Gauge should read 3.5" W.C. for natural gas or
10.0" W.C. for propane. AFTER TAKING PRESSURE READINGS,
BE SURE TO REPLACE CAP TO RESEAL. DO NOT OVER-TORQUE.
- Leak test with a soap and water solution.
- Ensure air shutter opening is free of lint or other obstructions.
- Open air shutter to increase the primary air.
- Check the input rate: check the manifold pressure and orifi ce size as
specifi ed by the rating plate values.
- Check that the door gasketing is not broken or missing and that the
seal is tight.
- Check that both 3" and 5" vent liners are free of holes and well
sealed at all joints.
- Check that the minimum rise per foot has been adhered to for any
horizontal venting.
- Clean the glass with a gas fi replace glass cleaner. DO NOT CLEAN
GLASS WHEN HOT. If deposits are not cleaned off regularly, the
glass may become permanently marked.
- Check door seal.
- Check for chimney blockage.
- Ensure that the paint curing process is complete.
- Connect a jumper wire across the wall switch terminals; if main
burner lights, replace switch / thermostat.
- Remove stoppage in orifi ce.
- Replace.
- Replace.
- Check that the manual valve is turned on.
- Replace the valve.
- Fill the tank.
- Check the power source. (ie. fuse, circuit breaker)
- Check that the wire is connected to both the ignitor and the control
module.
- Check that the spark is not jumping to ignitor cover.
- Replace the wire if the wire insulation is broken or frayed.
- Replace the electrode if the ceramic insulator is cracked or broken.
- Spark gap should be 0.125" (1/8" approx.) from the electrode tip to the
sensor tip.
- Reverse.
- Replace.
- Check for ground (short); repair ground or replace wire.
- Replace.
