•  A tall, lazy flame with dark orange tips requires more air – Open slider 

(pull out) slightly.

•  A short, brisk flame, like a blowtorch, has too much air – Close slider 

(push in) slightly.

•  If the flame is in the middle of these two characteristics with a bright 

yellow/orange,  active  flame  with  no  black  tips  then  the  air  is  set  for 

proper operation, refer to Figure 7.

The combustion exhaust blower is a variable speed blower controlled by 

the  heat  output  button.  This  blower  will  decrease  the  vacuum  pressure 

inside the stove, adjusting the air to fuel ratio. 

SPECIAL NOTES:

 

Fuel quality is a major factor in how the stove will operate. If the fuel has a 

high moisture content or ash content the fire will be less efficient and has 

a higher possibility of the fire building up and creating clinkers (hard ash 

build-up).

• 

MANUAL and HI / LOW mode: To turn the unit OFF, simply press the ON / OFF button. This will stop 

the feed of pellets. The blowers will continue to operate and cool the stove down. When cool enough, 

the stove will turn off.

• 

AUTO / OFF mode: To turn the unit OFF, turn the Thermostat down or Timer off. 

• 

Upon shut-down the burn pot agitator will run continually for two (2) minutes when on Pellet Fuel Type  

and fifteen (15) minutes when on Multi-fuel Fuel Type.

DO NOT turn unit off during start-up or unplug unit while operating; this may lead 

to smoke escaping from the stove.

Operating Instructions

Figure 6: Slider/Damper Plate in Unit.

If the fire should happen to go out and the heat 

output  indicator  has  been  set  on  the  lowest 

setting,  the  Slider  Damper  should  be  pushed  in 

slightly, decreasing the air in the firebox.

If, after long periods of burning, the fire builds up 

and overflows the burn pot or there is a build up of 

clinkers, this would be a sign that the fuel quality 

is poor, this requires more primary air, the slider 

damper must be pulled out to compensate. Pulling 

the slider damper out gives the fire more air.

The easiest way to make sure that an efficient flame 

is achieved is to understand the characteristics of 

the fire.
