Vermont Castings Defiant

WARNING: FIREPLACE STOVES EQUIPPED WITH
DOORS SHOULD BE OPERATED ONLY WITH
DOORS FULLY OPEN OR DOORS FULLY CLOSED.
IF DOORS ARE LEFT PARTLY OPEN, GAS AND
FLAME MAY BE DRAWN OUT OF THE FIREPLACE
STOVE OPENING, CREATING RISKS FROM BOTH
FIRE AND SMOKE.

The Defiant may be used as a fireplace with the
front doors open or removed, BUT

only when it is

equipped with 8" (200mm) stove pipe and only
when the optional spark screen is placed correctly
in the opening to protect against the possibility of
sparks and embers leaving your stove.

Use only the Defiant spark screen, Item #1907, with
your Defiant.

Defiant spark screens are available from your
Vermont Castings Majestic Products Company
Dealer.

Infra-Red Reflective Glass Panels

for Clear Fire Viewing

The outer surfaces of the ceramic glass panels have
an infrared-reflective coating which keeps the inner
surfaces warm. This design, along with a pre-heated
'airwash,' makes clear fire viewing possible at most
firing levels.

Andirons Help Protect the Glass

Your stove has andirons to keep logs away from the
glass panels. The andirons are essential to maintain
clear fireviewing, and should be left permanently in
place. Since the andirons may slightly hinder refueling
through the front doors, most stove owners will prefer
the convenience of top loading through the griddle. Do
not place fuel between the andirons and the doors.

Burn Only High-Quality Wood

The Defiant 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. The wood should
be 20-22" (500-550 mm) in length. Avoid burning
“green” wood that has not been properly seasoned.
Do not burn construction materials; they often
contain chemicals and metals that can damage the
catalytic combustor or pollute the air. Do not burn
ocean driftwood; when it burns, the salt it absorbs will
attack the cast iron.

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.

If hardwood is not available, you can burn soft-

woods like include tamarack, yellow pine, white pine,
Eastern red cedar, fir, and redwood. These should
also be properly dried.

Store wood under cover to keep it dry. The longer

it is stored, the better heating and fire-viewing perfor-
mance you will enjoy. 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.

A Surface Thermometer is a Valuable

Guide to Operation

An optional surface thermometer tells you when to

adjust the air control, and when to refuel. (Fig. 26)

For example, when the thermometer registers at

least 450

°

F. (230 C) after start-up you know that the

stove is hot enough to begin catalytic combustion and
that it

may be time to close the damper. Note that the

stove will warm up much sooner than the chimney,
though; a warm

chimney is the key to easy, effective

stove operation. Please review the draft management
information on pages 24 to see how the size, type, and
location of your chimney will affect your stove opera-
tion. When thermometer readings drop below 350

°

F.

(175˚C) it’s time to adjust the air control for a higher
burn rate or to reload the stove. A temperature reading
over 750

°

F. (385˚C) is a sign to cut back on the air

supply to slow the burn rate.

Use the following temperature ranges as a guide:

• Readings in the 350-500

°

F. (175-260˚C) range

indicate low to medium heat output.

• 500-600

°

F. (260-315˚C) readings indicate medium

heat output.

• Readings of 600-750

°

F. (315-385˚C) indicate high

heat output. Operating your Defiant continuously at
griddle temperatures of 750

°

F. (385˚C) or higher may

damage the cast iron or enamel finish.
