TURN OFF THE STOVE AND THOROUGLY CLEAN ALL STOVE AREAS AS PER MAINTENANCE DIRECTIONS.
WHEN OPERATING NORMALLY, THIS APPLIANCE COULD TRIGGER SMOKE DETECTORS INSTALLED TOO
CLOSE TO THE UNIT.
Loading Pellets
Lift the hopper door vertically until fully opened, open secondary hopper door; add pellets into hopper until full.
In order to maximize hopper capacity, push pellets into void spaces. With all voids full, maximum hopper
capacity is approximately 50 lbs of pellets. To reduce the introduction of fines, or spillage, we recommend the
use of a secondary container to add pellets. Clean up any pellets spilled on, or down inside the stove.
Store pellets in a dry location, and outside the required clearances to combustibles of the heater.
NOTES:
WARNING! TOP GRILL AND FRONT EDGE OF STOVE CAN BECOME VERY HOT, AVOID ALL CONTACT WITH
HEATED SURFACES
IF THE HOPPER DOOR IS LEFT OPEN, A CAP OPEN MESSAGE WILL SHOW ON THE DISPLAY. AN OPEN
HOPPER DOOR WILL AUTOMATICALLY STOP FUNCTION OF THE FEED AUGER, AS THE AUGER POSES A
HAZARD TO FINGERS DURING OPERATION. TO ACKNOWLEDGE THIS MESSAGE, SIMPLY CLOSE THE
HOPPER DOOR.
All operations of the stove are initiated from the User Interface pad. This pad is designed to provide simple,
user-friendly operation of the stove. There are only four buttons on the interface pad, Power (On/Off), MENU,
+, -. During normal operation, the interface screen will illuminate red. When the unit is in OFF mode, but power
is supplied, the pad will display its operational state without the red backlighting. If an error is detected, an error
message is displayed, and the readout will flash.
