Draft Adjuster - Adjustment Procedure
The Winslow™ PS40 stove has a draft adjuster located at the left side
of the stove directly in front of the combustion blower. Should the stove
installation require long runs of vent pipe, a situation may be created
where excessive combustion air is flowing through the firebox and
causing the fuel to burn faster than it can be delivered to the Burn-Pot.
Should this happen, the draft can be slowed down by the adjuster. The
stove is shipped with the adjuster in the fully open position. To slow the
draft down, loosen the 5/32” allen head screw (A in Figure 54) and move
the adjuster handle toward the center of the stove. Retighten the screw
when the desired adjustment is reached.
Draft Adjuster
The draft adjuster controls the amount of combustion air that is delivered
to the firebox (see Figure 54).
It will be necessary to monitor the appearance of the flame during the first
4-8 bags of pellets. If the flame is smoky red or orange with evidence of
soot at the top of the flame, the draft adjuster will need to be adjusted
to deliver more combustion air. If the flame is "short" at the higher burn
rates, and appears to burn the pellets out of the pot faster than they can
be resupplied, or there are significant variations of flame height within a
single burn setting, the draft adjuster may need to be adjusted to deliver
less combustion air.

After the draft adjuster is adjusted, re-evaluate the appearance of the
flame. It may be necessary to continue adjusting it in increments until
proper combustion is achieved (the flame should become a brighter
yellow and begin to “dance”).
Once the draft adjuster has been properly set, and if the routine main-
tenance is performed as needed, the draft adjuster should not require
readjustment unless you are changing from a premium grade pellet
to a standard or high ash pellet, in which case the draft adjuster may
need to be moved outward from center of the stove to help prevent the
accumulation of ash or clinkers in the Burn-Pot.
