SYMPTOM ACTION
The main burner does not turn
on with the pilot lit. Cont... 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 the 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 185-
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 appli-
ances.
2. Check for good pilot flames on the thermopile.
3. Check for good voltage from the thermopile.
4. If venting is suspected, refer to the venting section of this manual for
proper venting practices.
5. Check wire connections. Expansion from heat affects a loose connection.
Sooty deposits on the glass
door. 1. If the flame is yellow and lazy, check for lint etc. around primary air shut-
ter. 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 proper venting and blockage of the vent termination.
4. 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 120 VAC 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.
