PROBLEM
SOLUTION
The appliance
keeps going out.
-
Due to different installation set ups, length and size of venting and fuel quality, the
low feed setting from the factory will not always be correct. It may be necessary to
experiment with feed rate vs air control.
-
If the appliance goes out and leaves fresh unburned pellets or cigarette-like ashes in
the burn pot, the
fi
re is going out before the appliance shuts off.
-
Check to see if the appliance needs a more complete cleaning as well as the burn
pot, venting, etc...
-
Was there a power failure?
-
Trim feed rate and exhaust blower speed.
-
If the appliance goes out and there are no pellets in the burn pot, the auger may be
slipping. See “THE AUGER MOTOR WILL NOT FUNCTION NORMALLY” and “THE
EXHAUST BLOWER WILL NOT FUNCTION NORMALLY” section.
Excessive carbon
build up in the
fi
rebox, low heat
output.
-
Check quality of pellets. Even pellets from the same manufacturer can vary in quality
since the materials they use to form pellets may also vary.
-
Moisture content of pellets too high. Pellets must be stored in a dry place. Areas such
as a garage are too damp causing pellets to absorb moisture.
-
Trim feed rate and exhaust blower speed.
Appliance is
burning dirty and
lazy.
-
Check that all exhaust and intake pathways are clear of any obstructions.
-
Burn pot is clean.
-
Pellets are dry.
-
Venting and terminal are clear of obstructions.
-
Exhaust blower is operating and is clean.
-
The trim setting could be too low. Press and hold the prime button and advance it to
the next trim setting.
-
It is normal for the glass on pellet burning appliance to accumulate a tan colour build-
up of
fl
y ash. Burning on the low settings will produce a darker colour. A heavy dark
build-up could indicate a problem. See “CARE OF GLASS” section.
The low limit
temperature sensor
has tripped.
Check that
your low burn is
consistent.
-
Temporarily bypass the low limit switch by disconnecting the two brown wires and
connecting them together with a short piece of wire. Then plug the appliance back in.
If the appliance comes back on and works, you need to replace the low limit switch.
This is for testing only. DO NOT LEAVE THE SWITCH BYPASSED. Your blowers will
never shut off and if the
fi
re went out the auger will continue to feed pellets until the
hopper is empty if you leave the low limit switch bypassed.
-
If the fuse on the control board has blown, remove the fuse. If the fuse appears to be defective,
replace it with a 5 Amp 250 Volt fuse. Plug the appliance back in and try to run the appliance.
The vacuum
switch has been
tripped.
-
Vacuum hose or
fi
ttings may be blocked. Unhook the hose from the vacuum switch and
blow through it. If air
fl
ows freely, the hose and tube are
fi
ne. If air will not
fl
ow through the
hose, use a wire coat hanger to clear the blockage.
-
If the air inlet, burnpot, interior combustion air chambers, combustion blower, or exhaust
pipe are blocked with ash or foreign material, then follow all cleaning procedures in the
maintenance of the manual.
-
The
fi
rebox might not be properly sealed. Make sure the door is closed and that the gasket
is in good shape.
-
Make sure the vent pipe is installed correctly.
-
The vacuum switch wire connections might be bad. Check the connectors that attach the
blue wires to the vacuum switch.
-
The gray wires are pulled loose at the connector on the wiring harness. Check to see if the
blue wires are loose at the connector.
-
Combustion blower failure. With the appliance 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 at 115 Volts. If there is power, the blower is defective. If there is not, see the next step.
-
Control board not sending power to the 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 defective control board.
-
Control board not sending power to vacuum switch. There should be a 5 Volt current
(approx.) going to the vacuum switch after the appliance has been on for 30 seconds.
-
Vacuum switch has failed (very rare). To test the vacuum switch, you will need to disconnect the
air hose from the body of the appliance. With the other end still attached to the vacuum switch,
very gently suck on the loose end of the hose (you may want to remove the hose entirely off the
appliance and the vacuum switch
fi
rst and make sure it is clear). If you hear a click, the vacuum
switch is working. BE CAREFUL, TOO MUCH VACUUM CAN DAMAGE THE VACUUM SWITCH.
