SYMPTOM ACTION
The main burner does not turn
on with the pilot lit. (cont’d) 3. Check to make sure the thermostat is set high enough to turn on the
appliance.
4. Check that the remote switch or the thermostat is turned on.
5. Check for weak pilot flame. If flame is weak, check gas supply,
check pilot flame adjustment and check for blockage of pilot orifice.
6. Check all connections to the valve for tight electrical contact.
7. Check for 400-500 mV from the thermopile with the burner off and
200-250 mV with the burner on. If the voltages are lower, the
thermopile is defective.
8. Check for defective gas valve.
The main burner shuts off
when the appliance is warm. 1. This may be the normal operation of a wall thermostat installed to
appliances.
2. Check for good pilot flames on the thermopile (see page 30).
3. Check for good voltage from the thermopile.
4. Check for proper functioning of venting system.
5. Check wire connections. Expansion from heat affects a loose con-
nection
Sooty deposits on the glass
door. 1. If the flame is yellow and lazy, check for lint etc. around primary air
shutter. Increase primary air by opening the primary air shutter if
necessary.
2. Check for proper placement of the logs and branches. Ensure logs
and burner are clean. See that section in the instruction manual.
3. Check for obstruction of the burner ports by the embers. See that
section in the instruction manual.
4. Check for proper venting and blockage of the vent termination.
5. Check manifold pressure and clock input rating for over-firing.
Sharp blue flames with flames
lifting off the burner at the
ends. 1. Too much primary air. Reduce primary air by closing the primary air
shutter. During cold temperatures, some flame lifting may occur
during start-up.
Convection blower does not
turn on.
1. The convection fan is thermostatically controlled. It will only turn on
when the appliance is warmed-up. This may take up to 15 minutes
with the appliance on high.
2. Check for 120VAC electrical supply to the appliance. (Is the cord
plugged in?)
3. Check for proper mounting of the thermal snap disc.
4. Check electrical connections.
5. Check for defective thermal snap disc.
6. Check for defective convection blower speed controller.
7. Check for defective convection blower.
