Ashby-P Insert
37
Combustion Air Damper
Do not neglect to
adjust the Combustion Air
damper during the break in period of your
new Insert
(See Figure 20 to the left).
Your
Ashby-P Insert 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. The damper will
most likely only need a small adjustment
during the break in period. To know if the
damper needs to be adjusted you should
learn to recognize how Pellets burn in the
Ashby-P Insert with the Versa Grate system.
Figure 20
Procedure for adjusting the damper when burning the Ashby-P:
When burning the Ashby, the adjustment to the damper must primarily focus on how
Insert runs on the low setting.
(Read “PREVENTING CHIMNEY FIRES” on Page 26)
a.
If a
heavy
black shiny build (difficult to wipe off) up is noticed (on the glass and
inner surfaces) after the unit runs on the low (pilot) setting for extended periods of
time, the damper must be closed some. This may not show up until the Insert runs
in pilot mode (Heat Level 1) for an extended period of time. If this build up
occurs, slide the damper control 1/16
th
” at a time to close the damper until the
glass improves. Some build up is normal and may be removed during the
maintenance schedule.
b.
Once the adjustment has been made for the pilot setting (Heat Level 1), slowly
advance the Control Board to the #5 Heat Level and observe the flame. If black
soot (wipes off easily) builds up on the glass and black smoke is visible at the tips
of the flames, slide the damper control 1/16
th
” at a time to open the damper. Wait
5 – 10 minutes before attempting another adjustment. An occasional wisp of black
smoke is normal.
