e.
Advance the heat setting to #5 and let the Furnace burn at this setting for ½ an
hour. Check the burn pot to see if it is balanced. A small damper adjustment
might need to be made at this time to make sure the “
Lag time”
isn’t too long.
Remember:
Only turn the setscrew one 1/2 turn
clockwise
to open the damper.
Wait 15 minutes to see if the burn pot becomes balanced. Repeat this step as
many times as needed until the burn pot becomes balanced.
If the Furnace has been connected to an existing Chimney system that has good natural
draft, the procedure mentioned in the last 2 points above may actually require that the
damper gets closed slightly instead of opened to compensate for the additional draft in the
chimney system.
The process of adjusting the damper when burning Corn, wheat or rye will take about 3
hours, but it only needs to be done once at the initial burn. This will adjust the Furnace to
the unique circumstances of your home.
Procedure for adjusting the damper when burning Pellets:
When burning pellets in the Furnace, the adjustment to the damper will most likely need to
be made when the Furnace is running in the pilot mode.
a.
If a
heavy
black shiny build (difficult to wipe off) up is noticed, on the glass and inner
surfaces, after the furnace runs on the low (pilot) setting for extended periods of time,
the damper must be closed some. This may require the Furnace to run in pilot mode
for a while to become noticeable. If this build up is noticed, close the damper 50% to
start out with, and place the setscrew against the damper blade. Use this as the
starting point to make additional adjustments with the setscrew. Some build up is
normal and may be removed during the maintenance schedule.
b.
Once the adjustment has been made for the pilot setting slowly advance the Furnace
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 turn the setscrew one
½ turn counterclockwise and bring the damper blade up against the screw. Wait 5 –
10 minutes before attempting another adjustment. An occasional wisp of black smoke
is normal every now and then.
