Encore Woodburning Stove

Infrared Reﬂective Glass Panels

for Clear Fire Viewing

The inner surfaces of the infrared reﬂective glass

panels are kept at a higher temperature than the outer

surface. This design, along with a preheated ‘airwash,’

makes clear ﬁre viewing possible at most levels of

operation.

A Surface Thermometer is a

Valuable Guide to Operation

An optional surface thermometer lets you know when

to adjust the air control, when to refuel, and when your

catalyst is operating properly.

For example, when the thermometer registers at least

450°F (230°C) after start-up you know the stove is hot

enough to begin catalytic combustion 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

Pages 25-27 to see how the size, type, and location

of your chimney will affect your stove operation. 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.

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.

Burn Only High-Quality Wood

The Encore 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. Avoid burning “green”

wood that has not been properly seasoned, or cord-

wood dried more than two years. Do not burn con-

struction materials; they often contain chemicals and

metals that can damage the catalytic combustor. The

wood should be 18-20” (400-500mm) in length.

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

which include tamarack, yellow pine, white pine, East-

ern red cedar, ﬁr, and redwood. These too should be

properly dried.

Store wood under cover to keep it dry. The longer it is

stored, the better heating and ﬁreviewing performance

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.

Use the following temperature ranges as a guide to

operation:

• Readings in the 350-500°F (175-260°C) range

indicate low to medium heat output.

• 500-600°F (260-315°C) readings indicate me-

dium heat output.

• Readings of 600-750°F (315-400°C) indicate

high heat output. Operating your Encore continuously

at griddle temperatures of 750°F (385°C) or higher may

damage the cast iron or enamel ﬁnish.

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; outdoor air temperature and pressure

also affect draft.

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.

Refer to Pages 25-27 for details on how the installation

affects performance.
