Vermont Castings Defiant FlexBurn Homeowner's Installation And Operating Manual page 23

To reduce the risk of breaking the glass, avoid striking the
glass or slamming the doors.
When you are not using the door handle, store it in the
holder behind the right front leg of the stove. Be careful to
not drop the handle, since it is breakable.
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, creat-
ing risks from both fire and smoke.
waRNiNg: For safety and greatest efficiency, operate
your stove only with all doors/griddles fully closed.
The test standard for your stove when it is operated
in this mode is Ul 1482.
The Defiant may be used as a fireplace with the front
doors open or removed, bUT only when it is equipped
with 8" (203 mm) stove pipe and only when the optional
spark screen is secured correctly in the opening to
protect against the possibility of sparks and embers
leaving the stove. The test standard for your stove
when it is operated in this mode is Ul 737. 1" floor
protection is also required. Refer to "Floor protection"
section on pages 10 - 11.
Use only the Defiant spark screen, item #1907, with
your Defiant.
Defiant spark screens are available from your vermont
castings Dealer.
andirons help protect the glass
Your stove has andirons to keep logs away from the glass
panels. The andirons are essential to maintain clear fire
viewing, 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.
iMpoRTaNT: Do not burn any type of artificial or syn-
thetic materials such as fire starter logs (containing
wax) in this appliance. Never burn liquid-based fuels
such as kerosene, gasoline or alcohol.
burning any materials not allowed in these instructions,
or over-firing the stove, may void the warranty.
You'll enjoy the best results when burning wood that has
been adequately air-dried. The wood should be 22-24"
(559-610 mm) in length. Avoid burning "green" wood that
has not been properly seasoned. Do not burn construc-
tion materials; they often contain chemicals and metals

that can damage the inside surfaces of the stove and pol-
lute the air. Do not burn ocean driftwood; when it burns,
the salt it contains 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 softwoods that in-
clude 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 performance
you will enjoy. Even for short-term storage, be sure to
keep wood a safe distance from the heater and keep it
out of the areas around the heater used for refueling and
ash removal.
An optional surface thermometer tells you when to adjust
the air control, and when to refuel. (Fig. 36)
Fig. 36 Take temperature readings with a thermometer located
in the middle of the griddle.
For example, when the thermometer registers at least
450°F. (230°C) after start-up you know the stove is hot
enough and 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 Page 27 to see how the size, type, and location of your
chimney will affect your stove operation. When thermom-
eter 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 indi-
cate 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.
