TROUBLE SHOOTING GUIDE

STOVE FEEDS PELLETS, BUT WILL NOT IGNITE

Possible Causes

Possible Remedies: (Unplug stove 

fi

 rst when possible)

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 

fl

 ame, 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 

fi

 rewall.  The 

air intake hole is a small hole located on 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 

fi

 rebox.

Make sure that the air intake collar on the burnpot is touching 
the rear wall of the 

fi

 rebox.

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.

5.  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 current, check 
the wiring.  If the wiring checks out good, the board is bad.

SMOKE SMELL COMING BACK INTO THE HOME

Possible Causes

Possib

le Remedies: (Unplug stove

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 on 
500 degree 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.

Because it is a wood-burning device, your pellet heater may emit a faint wood-burning odor. If this increases beyond 
normal, or if you notice an unusual soot build-up on walls or furniture, check your exhaust system carefully for leaks. 
All joints should be properly sealed. Also clean your stove, following instructions in “MAINTENANCE”. If problem 
persists, contact your dealer.

CONVECTION BLOWER SHUTS OFF AND COMES BACK ON

Possible Causes

Possible Remedies: (Unplug stove 

fi

 rst when possible)

1.  The convection blower is overheating and tripping 

the internal temperature shutoff.

Clean any dust off of the windings and fan blades.  If cleaning 
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, then the 
control board is 

fi

 ne.  If there is NOT power being sent to the 

blower when it shuts off during operation, then you have a 
bad control board.
