TROUBLESHOOTING GUIDE

21

1.    Air damper open too far for ignition.

Push the air damper in closer to the side of the stove for 

startup. In some situations, it may be necessary to have the 

damper completely closed for ignition to take place. After 

there is a flame, the damper can then be adjusted for the 

desired feed setting. 

2.    Blockage in igniter tube or inlet for igniter tube.

Find the igniter housing on the backside of the firewall. The 

air intake hole is a small hole located on the bottom side of 

the housing. Make sure it is clear. Also, look from the front 

of the stove to make sure there is not any debris around the 

igniter element inside of the  igniter housing. 

3.    The burnpot is not pushed completely to the rear of  

         the firebox.

Make sure that the air intake collar on the burnpot is touch-

ing the rear wall of the firebox. 

4.    Bad igniter element.

Put power directly to the igniter element. Watch the tip of the 

igniter from the front of the stove. After about 2 minutes, the 

tip should glow. If it does not, the element is bad.

The control board is not sending power to the igniter.

Check the voltage going to the igniter during startup. It 

should be a full current. If the voltage is lower than full cur-

rent, check the wiring. If the wiring checks out good, the 

board is bad. 

1.    There is a leak in the vent pipe system.

Inspect all vent pipe connections. Make sure they are 

sealed with RTV silicone that has a temperature rating of 

500

o

F or higher. Also, seal joints with UL-181-AP foil tape. 

Also, make sure the square to round adapter piece on the 

combustion blower has been properly sealed with the same 

RTV.

2.    The gasket on the combustion blower has gone 

       bad.

Inspect both gaskets on the combustion blower to make 

sure they are in good shape. 

1.    The convection blower is overheating and

         tripping the internal temperature shutoff. 

Clean any dust off the windings and fan blades. If clearing 

the blower does not help, the blower may be bad.

2.    Circuit board malfunction.

Test the current going to the convection blower. If there is 

power being sent to the blower when it is shut off, the 

control board is fine. If there is NOT power being sent to the 

blower when it shuts off during operation, then you have a 

bad control board.
