Importance of proper Draft
Do not neglect to
adjust the Combustion Air Damper during the break in period of your new
Stove
(See Figure 18).
Your Stove is equipped with an air inlet damper. The purpose of this
damper is to adjust combustion airflow to match the characteristic of each specific air inlet and
chimney configuration. See figure 19 for initial damper settings for pellets. The damper will
most likely only need a small adjustment during the break-in period. Break-in requires the
burning 15 bags of pellets or a continuous burn for two weeks.
If you notice a difference in the operation of the Stove,
first check to see if there has been a
change in the fuel you are burning.
If the fuel properties have significantly changed,
such as
the
fuel is very dirty, then making a change to the damper is correct.
However if the Stove needs cleaning,
changing the Damper may mask the fact that the stove is
getting plugged.
It is always a good idea to thoroughly clean your stove before making a
significant damper change.
If you experience problems adjusting the Stove during the Break-In Period, contact your
dealer.
Some chimney systems will fall outside the norm, for example, a chimney with excessive
draft or one with a long horizontal run.
Figure 18 shows the location of the damper control
lever. The tabs and notches shown each represent
1/16”. See figure 19 and note the location where the
damper handle stops towards the closed position and
then note the location where the damper stops
towards the open position.

Units connected to a
Horizontal Vent
system by using the “Zero Clearance Cabinet as shown in
figure 6 or vented as shown in figure 13 will require the damper to be open further, start by
opening the damper an additional 1/16” to compensate for any restriction due to venting
horizontally.
