C. Priming the Feed Tube
If the hopper is being filled for the first time or the unit had
previously run out of pellets, the feed tube may need to
be primed. To do this, turn the dial control from the OFF
position to the MAX position two times. This will run the
feed motor continuously for two minutes without turning
the igniter on. When the auger is running continuously,
the LED will be a continuous green color. The system
will run the auger for 2 minutes. When pellets start to
drop into the firepot, the feed tube is primed; turn the dial
control to the desired position and the stove will begin its
ignition sequence. (The green LED will flash rapidly) DO
NOT OVERFILL FIREPOT FOR IGNITION. If there are
excessive pellets in the firepot the starts will be extremely
smokey and cause an unstable ignition that includes but
not limited to rumbling and whistling.
D. Firepot Purge Cycle
A feature of these pellet stoves is the firepot purge cycle.
The frequency of the purge cycle is once every hour the
unit is burning. During this purge, the feed is reduced to
a minimum setting and the exhaust blower ramps up to
the maximum setting. The purpose of the purge is to help
remove debris from the firepot and help the unit burn as
efficient as possible. The purge cycle lasts 99 seconds.
Please be aware that the purge cycle does not replace
daily cleaning activities but makes them easier.
E. Shutdown
T
o shut the appliance down, turn the dial control counter
clockwise to the OFF position. During the shutdown pro-
cess, the LED will flash green rapidly just like the ignition
sequence. The firepot purge cycle will begin but without
the feed motor running. The feed will be terminated
during this shutdown process. The exhaust and convec-
tion blowers will remain on during the shutdown process
until the exhaust has cooled.
If maintenance or daily cleaning is going to be conducted
immediately following a shutdown, please use caution as
components especially those inside the firebox may still
be hot.
Please note that if the dial control is turned to the off
position and back on even if by mistake, the unit will
go through the shutdown sequence.

F. Starting Your First Fire
1) Turn the dial control to "OFF".
2) Make sure the firepot is clean, inplace, and free of
debris.
3) Plug the unit into the wall and fill the hopper with
wood pellets. Shut the hopper lid.
4) Turn the dial control to the desired burn setting.
The unit will go into the ignition sequence followed by
start up (The green LED will flash rapidly). The igni-
tion sequence involves the exhaust blower turning on,
the igniter turning on, and the feed motor running in two
stages. The first stage involves the feed motor running
continuously for about a minute to preload pellets into the
firepot. Following the preload and a delay, the feed motor
will begin cycling on and off. When the pellets are warm-
ing up and on the verge of igniting, it is not uncommon
for the firebox to fill with smoke. Once ignition actually
happens, the smoke should evacuate quickly. During this
stage as well as any part during the burn process, the
front door should not be opened. This cycle continues
until the unit senses ignition by a rise in the exhaust tem-
perature or the unit times out. Following the ignition cycle
the unit begins to feed additional pellets gradually for a
few minutes to build up the fire. This is important to have
a controlled start up to keep the unit in balance.
G. Fire Characteristics
The overall height of the flame will vary throughout the
burn for a couple of reasons. First is that the flame will
vary based on type of fuel or even batch of fuel. Sen-
condly, the unit adjusts the burn rate according to the how
far away the room temperature is from the set tempera-
ture. This should not cause alarm. The third character-
istic that affects the fire relates to general maintenance
and cleaning. Infrequent or poor general maintenance
will result is poorer performance. Indicators of the need
for additional maintenance activities include a lazy flame,
black sooted glass, pellets not igniting, or pellets falling to
the side of the firepot. See the maintenance section for
additional information.
