When your stove acts out of the ordinary, the rst reaction is to call for help. This guide may save time and money
by enabling you to solve simple problems yourself. Problems encountered are often the result of only ve factors:
1) poor fuel; 2) poor operation or maintenance; 3) poor installation; 4) component failure; 5) factory defect. You
can usually solve those problems related to 1 and 2. Your dealer can solve problems relating to 3, 4 and 5. Refer
to diagrams on page 25 to help locate indicated parts.
For the sake of troubleshooting and using this guide to assist you, you should look at your heat level setting to see
which light is ashing.
Disconnect the power cord before performing any maintenance! NOTE: Turning the ON/OFF Switch to ”OFF”
does not disconnect all power to the electrical components of the stove.
Never try to repair or replace any part of the stove unless instructions for doing so are given in this manual. All
other work should be done by a trained technician.
Trouble Shooting Guide
Display is Flashing “E1”
Possible Causes Possible Remedies: (Unplug stove rst when possible)
The convection blower is overheating and
tripping the internal temperature shutoff.
Clean any dust off of the windings and fan blade. If oiling the blower
does not help, the blower may be bad.
The stove is being left on the highest setting for
extended periods of time.
If operating the heater on the highest heat setting, the room temperature
could increase enough and lead to potential overheating situations. If
this happens try operating at a lower heat setting.
Fuel other than wood pellets is being burned in
the stove.
This pellet stove is designed and tested to use wood pellets. Check for
signs of fuel other than wood pellets. No other types of fuel have been
approved for this pellet stove. If there are signs of other types of fuel
being used, stop using them immediately.
Power surge or brown out situation.
A power surge, spike, or voltage drop could cause the high limit switch
to trip. Check to see if a surge protector is being used on the stove. If not,
recommend one to the customer.
High Limit Switch is malfunctioning. If the other items check out OK, replace the high limit switch.

Possible Causes Possible Remedies: (Unplug stove rst when possible)
Airow switch hose or stove attachment pipes for
hose are blocked.
Unhook air hose from the air switch and blow through it. If air ows freely,
the hose and tube are ne. If air will not ow throw the hose, use a wire
coat hanger to clear the blockage.
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.
The rebox is not properly sealed. Make sure the door is closed and that the gasket is in good shape.
Vent pipe is incorrectly installed.
Check to make sure vent pipe installation meets criteria in owner’s
manual.
The airow switch wire connections are bad. Check the connectors that attach the gray wires to the air switch.
Combustion blower failure.
With the stove on, check to see if the combustion blower is running. If it is
not, you will need to check for power going to the combustion blower. It
should be a full current. If there is power, the blower is bad. If there is not.
Control board not sending power to combustion
blower.
If there is no current going to the combustion blower, check all wire
connections. If all wires are properly connected, you have a bad control
board.
Control board not sending power to air switch.
There should be a 5-volt current (approximately) going to the air switch
after the stove has been on for 30 seconds.
Air switch has failed.
To test the air switch, you will need to disconnect the air hose from the
body of the stove. With the other end still attached to the air switch,
very gently suck on the loose end of the hose (you may want to remove
the hose entirely off the stove and the air switch rst and make sure it
is clear). If you hear a click, the air switch is working. BE CAREFUL TOO
MUCH VACUUM CAN DAMAGE THE AIR SWITCH.
