STOVE FEEDS PELLETS, BUT WILL NOT IGNITE
Possible Causes
Possible Remedies: (Unplug stove first when possible)
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.
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 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.
The burnpot is not pushed completely to the
rear of the firebox.
Make sure that the air intake collar on the burnpot is touching the rear
wall of the firebox.
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 current, check the wiring. If the
wiring checks out good, the board is bad.
SMOKE SMELL COMING BACK INTO THE HOME
Possible Causes
Possible Remedies: (Unplug stove first when possible)
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.
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.
HIGH LIMIT SWITCH KEEPS TRIPPING
Possible Causes
Possible Remedies: (Unplug stove first when possible)
The convection blower is overheating and
tripping the internal temperature shutoff.
Clean any dust off of the windings and fan blades. 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 consumer.
High limit switch is malfunctioning.
If the other items check out OK, replace the high limit switch.
