When your stove acts out of the ordinary, the first 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 five 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 17
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 flashing.

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
STOVE ShuTS OFF AND ThE #2 LighT FLAShES
Possible Causes: Possible remedies: (unplug stove first when possible)
1. Airflow switch hose or stove attachment pipes for hose are blocked. Unhook air hose from the air switch and blow through it. If air flows
freely, the hose and tube are fine. If air will not flow throw the hose,
use a wire coat hanger to clear the blockage.
2. 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.
3. The firebox is not properly sealed. Make sure the door is closed and that the gasket is in good shape. If the
ash door has a latch, make sure the ash door is properly latched and the
gasket is sealing good. If the stove has just a small hole for the ashes
to fall through under the burnpot, make sure the slider plate is in place
to seal off the firebox floor.
4. Vent pipe is incorrectly installed. Check to make sure vent pipe installation meets criteria in owner’s manual.
5. The airflow switch wire connections are bad. Check the connectors that attach the gray wires to the air switch.
6. The gray wires are pulled loose at the Molex connector on the wiring
harness.
Check to see if the gray wires are loose at the Molex connector.
7. 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, see #8.
8. 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.
9. 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.
10. Air switch has failed (very rare).
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
first 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.
