Blocked Vent

Flyash that has been expelled by the exhaust blower will accumulate in the vent sections. Check the locations shown
below for flyash buildup, and, if necessary, clean the entire vent system.

Make sure the stove has fully cooled (approximately 25 minutes) before conducting service.

Check the vent sections for creosote
accumulation (indicating a poorly burning
stove). Accumulation over 1/4Ó must be
removed.

On vertically vented systems, the dirtiest
portion is often the point where the vent turns
upwards (i.e. the "Tee"). Fortunately, the "Tee"
has a built-in clean out cover. Remove the
cover and vacuum out. While open, use a
flashlight to look up the pellet vent to check for
build-up.

Make sure the cap is free of debris
(especially if it has a screen that could
become blocked).

Flyash will deposit along
sections that are horizontal.

Restrictor Adjustment

In some cases the vent will produce too much draft for the stove. This leads to an inefficient burn, and in some cases,
the flame going out. Excessive draft typically happens in tall vertical installations or very short horizontal installations.
The factory restrictor setting is wide open.

When to Adjust the Restrictor

¥

If un-burned pellets are expelled from the firepot often (make sure they are un-burned, not just cylindrical
embers), the restrictor needs adjustment.

¥

If on LOW the pellets burn too quickly and the flame goes out, the restrictor needs adjustment.

How to Adjust the Restrictor

Loosen this nut several turns.

a

b

c

d

Turn this bolt counter-clockwise to

push the restrictor in, increasing
restriction.

Use these index marks to gauge

restrictor movement. Move the restrictor
one position, then inspect the stoveÕs

performance over a long period of time.

TIghten the nut down (turn
it counter-clockwise).

7/16" Wrench

NOTE: You will not notice much change in the flame after

adjusting the restrictor. Check stove performance over a
long period of time.

WARNING: The stove must be

completely cool and unplugged
prior to beginning this procedure.
