How do you know if your draft is excessively high or low?
Symptoms of too much draft include an uncontrollable
burn or a glowing-red stove part. Signs of weak draft are
smoke leaking into the room through the stove or chimney
connector joints or low heat output.
In some newer homes that are well-insulated and weather-
tight, poor draft may result from an insufficient air supply
in the house. In such instances, an open window near the
stove on the windward side of the house can provide the
combustion air supply needed.
Another option for getting more combustion air to the stove
is to duct air directly from outside to the stove. In some
areas provisions for outside combustion air are required in
all new construction.
This appliance is equipped to deliver outside air for
combustion. An outside air adapter (available at your
authorized Vermont Castings dealer) is required for
installation and any 3" non combustible duct will need to
supplied by the installer.
When first using the stove, keep track of the air control
settings. You will quickly find that a specific setting will give
you a fixed amount of heat. It may take a week or two to
determine the amount of heat and the length of burn you
should expect from various settings.
Most installations do not require a large amount of
combustion air, especially if adequate draft is available.
Do not for any reason attempt to increase the firing of your
heater by altering the air control adjustment range outlined
in these directions.
Use the following air control settings as a starting point to
help determine the best settings for your installation. Each
is described as a fraction of the total distance the lever may
be moved from right to left.
F. Ash Disposal
IMPORTANT:
Check the level of ash in the ash pan before
reloading the stove. If the ash level is close to the top edge
of the pan, empty the pan according to this procedure:
• Open the damper.
• Open the griddle or front doors, and use a shovel or
poker to stir excess ash through the ash slots in the grate
down into the ash pan.
• Close the griddle or doors, and unlatch the ash door,
Figure 5.8. It will pivot, swinging the ash pan out of the
stove.
Figure 5.8
- Turn the ashdoor handle clockwise to open and
counterclockwise to close.

• Slide the cover onto the pan, making sure it is securely

WARNING
!
DO NOT OPERATE THE STOVE WITH THE ASH
DOOR OPEN. OPERATION WITH THE ASH DOOR
OPEN CAN CAUSE AN OVER-FIRING CONDITION TO
OCCUR. OVER-FIRING THE STOVE IS DANGEROUS
AND CAN RESULT IN PROPERTY DAMAGE, INJURY
OR LOSS OF LIFE.
Routine ash removal is important for ease of maintenance,
and is important for the stove’s durability. Remove ash
before it reaches the top of the ash pan. Check the level at
least once a day. Every few days, clear any ash from the
outer edges of the firebox. Most of the ash will fall through
the grate. Stir the ash with a shovel or poker so that it falls
through the grate slots.

- Be sure the cover is securely attached before removing
the ash pan.
• Remove the ash pan, making sure to keep it level.
• To keep the cover from sliding off and to keep ash from
falling on the floor, do not tilt the ash pan forward.
• If the stove is in operation, close the ash door while
disposing of the ash. You may need to lift the latch end
of the door slightly to align the latch with the mating part
on the stove bottom.
• Properly dispose of the ash in a metal container with a
tight-fitting lid. Store the container outdoors away from
all combustible material.
• Return the ash pan to its original position in the stove,
and close and latch the ash door.
