PROBLEM
Refer to section "JAMMED AUGER"
Check the vacuum sensor by placing a jumper wire
between the grey wire and the red wire that are attached
to the sensor. If the auger works, test to see if the exhaust
blower is producing enough vacuum (may require
cleaning). If not, replace the vacuum sensor.
Check quality of pellets. Even pellets from the same manu-
facturer can vary in quality since the materials they use to
form pellets may also vary. Use high quality pellets.
Use dry pellets. Pellets must be stored in a dry place.
Different vent confi gurations may cause excessive air to
consume the fi re too quickly before the next drop of fuel
therefore, leaving the fuel completely unburned in the burn
pot. This will cause the fuel to burn cold and very slowly.
Fuel also may build up and smother the fi re.
NOTE: The appliance may require a change to the vent
system or installation of fresh air to correct air to fuel ratio
problems.
Temporarily by pass the low limit switch by disconnecting
the two wires and connecting them together with a short
piece of wire. Plug the appliance back in. If the appliance
comes back on and functions properly, replace the low
limit switch.
NOTE: This step is for testing only. DO NOT LEAVE THE
SWITCH BYPASSED. If you leave the switch bypassed,
the blowers will never shut off and if the fi re went out,
the auger will continue to feed pellets until the hopper is
empty.
Ensure combustion blower is turning and the blower
blades are clean.
Check vacuum levels in the exhaust channel by bypass-
ing the vacuum switch. Remove the vacuum hose from
the vacuum switch. When checking the vacuum exhaust,
place the open end of the vacuum hose on the gauge
(readings must be above 0.10" W.C (0.25mb) on low fi re).
Bypass the sensor located on the exhaust blower. If the
appliance operates properly, the appliance may require
cleaning or a new sensor. Contact your local dealer for
service.
