in the grate. In extreme cases pellets can accumulate back up in the feed tube. Pellets can
smolder and produce smoke in the house. Once the damper is set for your particular fuel and installation, it will not
need to be readjusted unless a different type of pellet fuel is used. If the flame begins to look lazy, with a
red/orange colored flame, do not immediately adjust your damper. First check for ash build up either in the grate,
below the grate or in the vent system. These conditions can restrict the combustion air flow and upset the air-to-
fuel ratio. Remember to always shut your stove down and allow it to cool completely prior to cleaning. NOTE: If
the proper flame cannot be achieved with the damper control, adjustment of the trim controls may be necessary. (see
page 7)
INSERT STOVE DAMPER
The damper rod, on the Insert model stove projects out the
face of the shroud on the lower left side. All of the damper
information above also applies to the Insert stove. The 2"starting
point set dimension is measured between the surface of the
bottom plate and the inside surface of the set collar. These
adjustments are done with the black damper knob removed
and the side shroud panel swung open. When completing the
damper setting, the side shroud panel is closed allowing the
damper rod to pass through the slot in the panel, (as shown).
The plastic damper knob can now be threaded
back onto the damper rod.

The proper damper setting, to use as a starting point, is 2". It is set by pulling the
damper out all the way and measuring the distance between the side panel and the
inside surface of the set collar. If adjustment is required, loosen the set screw on the
set collar, with the allen wrench provided. The collar will now slide freely on the
damper rod. After adjustments have been made, tighten the collar set screw. The
damper rod must now be pushed in until the set collar contacts the side panel. This
completes the damper setting.
As stated the 2" setting is the recommended "starting point" for your stove. You may
need to change this setting depending on the venting configuration, site elevation or
This is the process that will provide the proper air-to-fuel ratio. If your flame is
red/orange with evidence of soot at the top of the flame, you need more air. Pull the
damper out until the flame becomes yellow and begins to "dance". If the air blows
pellets out of the grate or puts the fire out on low settings, you have too much air.
Push the damper farther in. When adjusting the damper, short 1/4"changes should
be used. Run the stove appx. 30 minutes before additional damper adjustments are
made. When your particular damper setting has been established, the set collar
should be loosened and positioned against the surface of the side panel. The collar
set screw must be tightened at this time. This is a safety feature to protect against acci-
dental damper closure. If the damper is accidentally pushed in too far, pellets can pile-up
STOVE BREAK-IN
Important Note: All stoves need to go through a break-in period. During this period,
(appx. 4-8 bags of pellets), the auger motor and the auger feed screw need to break
in to reach the specified fuel feed rate. Expect the fuel feeds and the flame appear-
ance to be low during this time. The damper will need to be readjusted after the
break-in period. It is recommended that the stove be monitored during this period.
Due to the fact that the pellet feed increases through the break-in period, the fuel-to-
air ratio could become imbalanced and pellets could pile up in the grate. Simply pull the
