vertical runs might need the damper to be closed
a little. To adjust the damper, use the Damper
knob on the right side of the insert, just above the
control board (See Figure 3 and 4). To make an
adjustment, turn the knob clockwise to close the
damper and counter clockwise to open the
damper. The knob only turns 90 degrees.
Do not
move the indicator more than 1/16” at a time.
After making an adjustment wait at least 15
minutes to see how the burn pot reacts to the
change. Additional Draft Adjustments can be
made for Heat Level 1 by using the “Draft Trim”
button on the control board (See point 4 on page
4).
Adjusting the damper during the break in
period is very important (See “Preventing
Chimney Fires” on page 3)
. Break-in requires
the burning of 15 bags of pellets or continuous
burn for two weeks. If during the initial break-in
period you experience difficulty keeping the
stove burning or there appears to be an excessive
amount of burning pellets being evacuated from
the burn grate, it may be necessary to close the
damper some more. Once the damper is adjusted,
the stove will run fine without having to make a
change to the damper setting, unless the stove is
run on 5 for extended periods of time
(See
“Flame Pattern Characteristics” in the column
to the right).
It is normal for ash and some
sparks to be continually evacuated from the burn
grate. This is how the grate continuously cleans
itself.
Figure

The equivalent of a teacup of unburned pellets a day
in the ash pan is considered normal.
Flame Pattern Characteristics
Correct Flame Pattern -
Bright yellowish-white
flame with a brisk movement, having sharp pointed
end tips extending up towards the Heat Exchange
Tubes while forming a fan-like shape. Small
amounts of ash and some live sparks being blown
out from the Burn Pot area is considered normal
operation.
Incorrect Flame Pattern -
Dark orangish-brown
flame with a lazy movement, having black smoky
end tips curling up and over the Heat Exchange
Tubes while forming a fireball-like shape. Some Ash
or Live Sparks not being blown out from the Burn
Pot area is considered abnormal operation.
Extremely black soot forming on the ceramic glass
surface is a sign of very poor combustion (not
enough combustion air) and should not be
overlooked. At the other end of the spectrum; an
extremely brisk flame which blows large pieces of
live coal out from the Burn Pot area and causes
stubborn shiny black build-up on the glass (too
much combustion air) is also considered undesirable.
If you experience problems adjusting the stove
during the Break-In Period, contact your dealer.
