The Fan
Heated air from the fireplace is forced into the room by
an internal fan. The control for the fan is in the right
corner of the unit.
“Off” is to the far left.
“High” is just to the right of “Off.”
“Low” is to the far right.
Variable adjustment of the fans is possible with any set-
ting between “high” and “low.”
For best results, coordinate fan speed with the setting
of the primary air control. For example, when the air
control lever is set at “low,” also set the fan at “low.”
With the air control set for maximum heat, set the fan at
“high.”
Glass Doors
The EWF36A is intended for use with the doors fully
closed or fully open only when optional spark screen
is installed. (Fig. 29) NOTE: When operated with the
doors open and spark screen in place, the damper
MUST be in the open position.
Burn Only High-Quality Wood
The EWF36A is designed to burn natural wood only; do
not burn fuels other than that for which it was designed.
You will enjoy the best results when burning wood that
has been adequately air-dried. Avoid burning “green”
wood that has not been properly seasoned.
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 year.
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 EWF36A will accept
wood up to 24” (610 mm). Longer wood pieces work
better than short ones.
Wood should be stored under cover to maintain dry
-
ness, and should be dried at least six months for
optimum heating and fire-viewing performance. 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 refueling and ash removal.
Use the Air Control Settings
that Work Best for You
No single air control setting will fit every situation. 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
installation’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.
Too much draft may cause excessive temperatures
in the fireplace. On the other hand, too little draft can
cause backpuffing into the room and/or the “plugging” of
the chimney or combustor.
How do you know if your draft is excessively high or
low? Symptoms of too much draft include an uncontrol-
lable burn or a glowing-red part of the EWF36A front. 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.
Another option for getting more combustion air to the
stove is to duct air directly from the outside to the stove.
In fact, in some areas provisions for outside combustion
air are required in all new construction.
Your EWF36A is designed so that it is possible to
incorporate outside air for combustion. Directions for
installing the optional AK-MST outside air ducts are
included with the kits and beginning on Page 11 of this
instruction.
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.
