SYMPTOM ACTION
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 flame sensor (see fig.3 page 9).
3. Check for proper functioning of venting system (including termination
for blockage).
4. Check wire connections. Expansion from heat affects a loose con-
nection
5. Check for adequate grounding from the Module ( page 27)
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 nec-
essary (See page 39for adjusting primary air)).
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 (See page 34 for adjusting primary air).
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 if speed controller is not in OFF position
4. Check for proper mounting of the thermal snap disc (under firebox).
5. Check electrical connections.
6. Check for defective thermal snap disc.
7. Check for defective convection blower speed controller.
8. Check for defective convection blower.
