Vermont Castings Encore Flexburn 2040 Homeowner's Installation And Operating Manual page 23

The control setting also depends on your particular installa-
tion's "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, local geography,
nearby obstructions, and other factors. See Page 26 for
details on how the installation affects performance.
Too much draft may cause excessive temperatures in the
Encore, and could even damage the stove. On the other
hand, too little draft can cause backpuffing into the room
and/or the "plugging" of the chimney.
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.
The Encore is equipped to deliver outside air for combus-
tion and outside air kit #3265 is available.
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 combus-
tion 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.

conditioning your Stove
Cast iron is extremely strong, but it can be broken with a
sharp blow from a hammer or from the thermal shock of
rapid and extreme temperature change.
The cast plates expand and contract with changes in
temperature. When you first begin using your Encore,
minimize thermal stress by letting the plates adjust gradu-
ally during three or four initial break-in fires following Steps
1-3 below.
Non-catalytic wood burning
Burn only solid wood in the Encore, and burn it directly
on the grate. Do not elevate the fuel. Do not burn coal or
other fuels.
The bypass damper must be open when starting a fire
or when refueling.
Do not use chemicals or fluids to start the fire. Do
not burn garbage. Never use flammable fluids such as
gasoline, gasoline type lantern fuel, kerosene, charcoal
lighter fluid, naptha, engine oil or similar liquids to
start or "freshen up" a fire in this heater. keep all such
liquids well away from the heater while it is in use.
1. Open the stove bypass damper, and open the primary
air control fully.
2. Place several sheets of crumpled newspaper in the
stove. Place six or eight pieces of dry kindling split to a
finger-width size on the paper. On the kindling, lay two
or three larger sticks of split dry wood approximately 1-2"
(25-51 mm) in diameter. (Fig. 36)
