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.

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. See Page 26 for details on how the installation affects performance.

Too much draft may cause excessive temperatures in the Defiant, and could even damage the combustor. 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 stove part. Signs of weak draft are 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 some areas provisions for outside combustion air are required in all new construction.

With an optional outside air adapter, No. 1904, your Defiant will accept a duct to deliver outside air for com- bustion.

When first using the stove, keep track of the air control settings. 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.

Use the following air control settings as a starting point to help determine the best settings for your installation. Each is described as a fraction of the total distance the lever may be moved from right to left.

High-Efficiency Wood Burning

with Catalytic Combustion

A Defiant leaves the factory with the combustor in- stalled.

In the United States, it is against the law to operate this wood heater in a manner inconsistent with operating instructions in this manual, or if the catalytic combustor is deactivated or removed. The components of the cata- lytic combustion system in your Defiant work together to produce optimum conditions for secondary combustion.

When the damper is closed, smoke travels through the catalytic element, which causes ignition of smoke at temperatures of 500°-600° F (260°-315°C), half the temperature normally required for unaided secondary combustion.

The catalytic element is a ceramic “honeycomb” coated with the catalytic material. The element is located in the secondary combustion chamber, molded from a special high-temperature insulating refractory material. The chamber provides the correct environment necessary for secondary combustion of the fuel (smoke).

Closing the damper exposes the smoke to the combus- tor. If the combustor is at least 600°F (315°C), it will begin to burn the smoke.

Closing the stove damper may also reduce the draft, so to avoid putting out the fire or deactivating the combus- tor, close the damper only when a fire is well-estab- lished and the chimney is thoroughly warmed. When starting a fire, wait until the fire is well established and there is an ember bed of at least 3-4 inches before clos- ing the damper.
