Intrepid 1640 Woodburning Stove
30000830
A more effective option for delivering ample combustion
air to the stove is to duct air directly from outdoors to
the stove. In fact, in some areas, provisions for outside
combustion air are required in all new construction. The
optional Intrepid Outside Air Adaptor is available from
your dealer.
When you first begin using the stove, pay attention
to the effects of different air control settings. You will
quickly find that a specific setting will give you a fixed
amount of heat. It may take some time to determine
the amount of heat and the length of burn you should
expect from various settings.
Do not for any reason attempt to increase the firing
of your heater by altering the air control adjustment
range outlined in these directions.
Before you start using the stove, please read the Ap-
pendix on Draft Management starting on Page 24 to
learn how the characteristics of your installation will
affect the stove’s performance. You and the stove are
parts of a system, and other parts of the system have a
strong effect on operation; you may need to vary your
firing technique to get the performance you want.
Starting and Maintaining a Fire
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 tempera-
ture. When you first begin using your Intrepid, minimize
thermal stress by allowing the plates to adjust gradually
during three or four initial break-in fires following
Steps

.
Burn solid wood fuel only, and burn it directly on
the grate. Do not elevate the fuel. Do not burn coal
or other fuels.
WARNING: operate this stove only with the door
fully closed.
The Primary Air Inlet must be open when starting a
fire or when refueling.
1. Open the primary air control fully by placing the Con-
trol Lever all the way to the LEFT (HIGH).
2. Place several sheets of crumpled newspaper in the
stove. Avoid using glossy or colored paper, as these
burn poorly. At the front of the firebox, place on the
paper six or eight pieces of dry kindling split to a
finger-width size, and on the kindling lay two or three
larger sticks of split dry wood approximately 1-2” (25-
50 mm) in diameter. (Fig. 28)
3. Light the newspaper and close the door. Gradually
build up the fire by adding a few 3-5” (80-120 mm)
diameter splits. (Fig. 29) If this is one of the first few
“break-in” fires, let the fire burn brightly, and then let
it die out.
