TROUBLESHOOTING GUIDE

23

1.    Stove or vent pipe is dirty, which restricts airflow    

       through the burnpot.

Follow all cleaning procedure in the maintenance section of 

the owner’s manual.

2.    Vent pipe installed improperly.

Check to make sure the vent pipe has been installed ac-

cording to the criteria in the owner’s manual.

3.    Air damper is set too far in (closed) for a higher 

       setting.

Put the damper knob farther out away from the side of the 

stove and try not to burn the unit again. 

4.    Burnpot holes are blocked. 

Remove the burnpot and thoroughly clean it. 

5.    Air damper is broken.  

Visually inspect the damper assembly. Make sure the damp-

er plate is attached to the damper rod. When the damper 

rod is moved, the plate should move with it. 

6.    Blockage in air intake pipe.

Visually inspect the air intake pipe that leads into the burn-

pot for foreign material.

7.    Circuit board malfunction.

Time the fuel feed light at each setting (after the stove has 

completed the startup cycle). Make sure the times match 

the auger timing chart. If the auger motor runs constantly, 

the board is bad. 

8.    Combustion blower is not spinning fast enough.

Test the RPM on the blower after the blades have been 

cleaned. The RPM should be approximately 3000RPM.

9.    Bad Pellets

       (Applies to “GLASS ‘SOOTS’ UP AT A VERY 

       FAST RATE” only.

The brand of pellets or the batch of pellets that are being 

used may be of poor quality. If possible, try a different brand 

of pellets. You might also want to try a brand that is made 

from a different type of wood (softwood vs. hardwood). 

Different woods have different characteristics when being 

burned.

10.   The trim setting on the low feed rate is too low.

        (Applies to “GLASS ‘SOOTS’ UP AT A VERY 

         FAST RATE” only. 

Use the “Reset Trim” button to increase the low feed rate 

setting. If the “1” & “3” lights are on, the stove is currently 

on the lowest setting. If only the “1” light is on, the stove is 

in the default (medium) setting. If the “1” & “4” lights are on, 

the stove is in the high trim setting for the low feed rate. If 

the stove is being burned on one of the two lower settings, 

advance to the next trim setting and try burning the stove.
