Disconnect the power cord before performing any maintenance! NOTE: Switching the appliance to ”OFF”
does not disconnect all power to the electrical components of the heater.
•
Never try to repair or replace any part of the heater unless instructions for doing so are given in this
manual or supplied from the factory. All other work should be done by a trained technician.
PROBLEM
CAUSE: To rich air/fuel mixture
Orange, lazy flame, excessive
fuel build-up in the burn pot
Clean out the burn pot and behind the cleanout door.
Make sure that the combustion door is closed and sealed properly. If
not, adjust door catch and/or replace door gaskets.
Check that the exhaust is clear of any obstructions. Clean as needed
Check for proper seating of the burn pot.
PROBLEM
CAUSE: Burn pot burns out of fuel
Fire goes out or heater shuts
down.
Hopper is empty, refill the hopper.
Loss of draft pressure. Make sure that the combustion door is closed
and sealed properly. If not, adjust door catch and/or replace door
gaskets. Check that the exhaust is clear of any obstructions. Clean as
needed.
Make sure the viewing door and hopper lid is closed completely.
Auger system is jammed or there is a “bridging” of the fuel in the
hopper, preventing fuel from flowing into the auger feed system.
PROBLEM
CAUSE: Auto-Start Igniter fails to ignite the fuel in the burn pot.
Heater does not start a fire when
the “ON” button is pushed
Turn the heater “OFF”. Clear the unburnt fuel from the burn pot and
try again.
Check the pellet quality. Replace if moist, wet, or dirty.
Loss of draft pressure. Make sure that the combustion door is closed
and sealed properly. If not, adjust door catch and/or replace door
gaskets. Check that the exhaust is clear of any obstructions. Clean as
needed.
Check that the auto-start igniter is not blocked with ash or soot.
(The igniter is located behind the burn pot on the back wall of the
combustion chamber.)
The auto-start igniter gets “red hot” during start-up. If you can not
visibly see the igniter glowing during start-up, then the igniter may
need to be replaced or there is a problem with the electrical control
system.
Check for proper alignment between the burn pot and the igniter tube.
PROBLEM
CAUSE: Heater has reached the 2nd over temperature limit.
Heater enters shut-down mode
To much fuel in the burn pot. Restart heater after heater has cooled.
RTD sensor in the room discharge air may be faulty causing the room
fan not to come on. Contact your dealer.
The air inlet, burnpot, interior
combustion air chambers,
combustion blower, or exhaust
pipe are blocked with ash or
foreign material.
Follow all cleaning procedures in the maintenance section of the
owner’s manual.
Pressure switch hose or stove
attachment pipes for hose are
blocked.
Unhook air hose from the pressure switch and blow through it. If air
flows freely, the hose and tube are fine. If air will not flow through the
hose, use a wire coat hanger to clear the blockage.
