when the power is reapplied a run button is pushed. If 12VDC is found then the relay has failed.

Heater starts then burns out - The start up is controlled by the control system and best results are from a cold start. If
a warm heater is im m ediately restarted it m ay not be able to confirm the required tem perature increase as the heater
tem perature is already warm and the tem perature is actually falling during the initial start up. Allow the heater to cool
and shut down before restarting.

Trim settings - W ill not change the first portion of the start up however will effect the initial run m ode. If the trim is fully
counter clockwise (Lowest) the heater m ay run low on fuel, m ost likely if the operating conditions are warm . High or
Max trim settings m ay cause the opposite problem as the heater feeds to m uch fuel and allows the HIGH TEM P
control stop the feed to cool the stove. Best starting trim setting is the m id point or 9:00 o-clock.

High tem p starts will also occur if the burn pot has additional fuel prior to start up. This additional fuel which is then
added too as the start cycle begins pushes the tem peratures up as the heater starts. This is considered an
tem perature overshoot as the tem perature clim bs quickly.

Heater will not start when run button is pushed - Check external therm ostat jum per or rem ote therm ostat as the unit
will not attem pt a start unless this circuit is closed.

Run mode Troubleshooting:

Once the heater reaches the run m ode it will continue operation by using the coals in the burn pot to light the pellets
continuing to fall. If the coal bed burns down at som e point the pellets m ay not light and then the heater will shut down.
This is norm ally confirm ed by finding the burn pot with unburned fuel and shut off. This can also happen if the hopper
runs low on fuel or the fuel bridges (hangs on the hopper sides).

Run m ode problem generally are either operational or lim its exceeded - Blocked Flue (loss of flue draft) or High
Tem perature is exceeded. Blocked flue indication is a solid RED LED on the control panel and requires a recycle of
the heater to clear. This is for the operators protection as a blocked flue could cause a dangerous condition. Block flue
m ost likely is not fully blocked and will occur if the flue pipe is subject to high wind conditions or is blocked by ash. If
this happens during initial installation a corrective action to the flue system will be required. Check the installation
m anual for flue recom m endations.

Operational problem s are generally related to ash build up in the burn pot or the heat exchange system and can be
correct by cleaning.

Over Feeding - Over feeding is a com m on problem and is related to a lack of com bustion air rather than to m uch fuel.
If the heater is clean and seem s to feed m ore fuel adjust the trim down to slow the feed rate. If the heater has been
operated for som etim e since the last cleaning then shutting it down and cleaning will solve the over feed. Check the
door for proper adjustm ent as a partially closed door will cause reduced com bustion air. Operating the heater for an
extended tim e with an open door will cause a shut down with RED LED and require a restart.

HI TEM P/FLUE RED W ARNING LIGHT:

W hen the Hi-Tem p/Flue indicator light com es on (red lite beneath control knob) it m eans a fault has been detected

in either the flue system , over tem perature, or fan/feed m otor.

Slow Flash Red Light - Indicates a blocked flue. Check flue and clean out for built up ash deposits.
Solid Red Light - Indicates an over tem perature. Check the air intake at rear of unit. Turn the feed trim down 25% to
reduce fuel rate.
Fast Flash Red Light - Requires unit to be unplugged to reset. Indicates a feed m otor jam or fan m otor fault. Fan
m otor test would require running unit on “fan and clean” only to determ ine if red light indication is repeated. If not, feed
system is jam m ed and requires the hopper access cover to be rem oved and jam m ed m aterial to be rem oved.

Shutdown:

Shut down is the sim plest m ode as the feed is stopped and the fan continues to operate until the heater is cool. If the
fan continues to run after it is fully cold then the T-2 sensor and the m ain control did not register the required
tem perature reduction. Unplug the heater to reset and run again. If problem persists then the T-2 sensor or the control
system will require com ponent replacem ent.
