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 may 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 mode. If the trim is fully counter clockwise (Lowest) the heater may run low on fuel, most 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 TEMP control stop the feed to cool the stove. Best starting trim setting is the mid 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 climbs 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 mode 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 some point the pellets may 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 mode 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 recomm 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 comm on problem and is related to a lack of combustion air rather than to much fuel. If the heater is clean and seems to feed m ore fuel adjust the trim down to slow the feed rate. If the heater has been operated for sometim 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 combustion 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 TEMP/FLUE RED WARNING LIGHT:

W hen the Hi-Tem p/Flue indicator light comes on (red lite beneath control knob) it means 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 motor 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 material to be rem oved.

Shutdown:

Shut down is the sim plest mode 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 main 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.
