Montpelier Medium Insert

Burn Only High-Quality Wood
The Montpelier Medium Insert is designed to burn
natural wood only; do not burn fuels other than that for
which it was designed.
You’ll enjoy the best results when burning wood that
has been adequately air-dried. Avoid burning “green”
wood that has not been properly seasoned or cordwood
that is more than two years old.
The best hardwood fuels include oak, maple, beech,
ash, and hickory that has been split, stacked, and air-
dried outside under cover for at least one to two years.
For areas that do not have a supply of hardwood, com-
monly burned softwoods include tamarack, yellow pine,
white pine, Eastern red cedar, fir, and redwood. These
too should be properly dried.
Your Montpelier Medium Insert will accept wood up to
18” (460mm). Longer wood pieces work better than
short ones.
Wood should be stored under cover to maintain dry-
ness. Even for short-term storage, however, keep wood
a safe distance from the heater and keep it out of the
areas around the heater used for re-fueling and ash
removal.
Use the Air Control Settings
that Work Best for You
No single air control setting will fit every situation. Set-
tings for each installation will differ depending on the
quality of the fuel, the amount of heat desired, and how
long you wish the fire to burn.
The control setting also depends on your particular
“draft,” or the force that moves air from the stove up
through the chimney. Draft is affected by such things as

the length, type, and location of the chimney, weather,
local geography, nearby obstructions, and other factors.
Too much draft may cause excessive temperatures in
the Montpelier Medium Insert, and could even damage
internal components. On the other hand, too little draft
can cause backpuffing into the room or a very sluggish
fire.
How do you know if your draft is excessively high or
low? Symptoms of too much draft include an uncontrol-
lable burn or glowing-red cast iron. A sign of inadequate
draft is smoke leaking into the room through the stove
or chimney connector joints, low heat, and dirty glass.
In some newer homes that are well-insulated and
weather-tight, poor draft may result from insufficient air
in the house. In such instances, an open window near
the stove on the windward side of the house will provide
the fresh air needed.
When first using the stove, keep track of the settings
of the air controls. 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 primary air control lever and fan
speed control lever settings as a starting point to help
determine the best settings for your installation.
