Defiant 1610CE Non-Catalytic Woodburning Stove

agement information on Page 26 to see how the size, type, and location of your chimney will affect your stove operation. When thermometer readings drop below 175° C (350° F) it is time to adjust the air control for a higher burn rate or to reload the stove. A temperature reading over 385° C (750° F) 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 175°-260° C (350°-500° F) range indicate low to medium heat output.

•260°-315° C (500°-600° F) readings indicate me- dium heat output.

•Readings of 315-385° C (600°-750° F) indicate high heat output. Operating your Defiant continuously at griddle temperatures of 385° C (750° F) 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 27 for details on how the installation affects performance.

Too much draft may cause excessive temperatures in the Defiant, and could even damage the stove. On the other hand, too little draft can cause backpuffing into the room and/or the “plugging” of the chimney.

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 or low heat output.

In some newer homes that are well-insulated and weather-tight, poor draft may result from an insufficient air supply in the house. In such instances, an open window near the stove on the windward side of the house can provide the combustion air supply needed.

Refer to Section 2 of Document J which requires an outside air vent for appliances with power outputs above 5 kW. Always refer to national and local codes to determine your specific requirements.

The Defiant NC is equipped to deliver outside air for combustion and outside air kit #3265 is available.

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.

Defiant Control Settings

(Refer to Figure 27, Page 19)

Burn Rate	Primary Air Control
Low	From far right to 1/3 the distance
	to left
Medium	From 1/3 to 2/3 the distance
	to left
High	From 2/3 the distance
	to left, to far left

DO NOT OPERATE THE STOVE WITH THE ASH DOOR OPEN. OPERATION WITH THE ASH DOOR OPEN CAN CAUSE AN OVERFIRING CONDITION TO OCCUR. OVERFIRING THE STOVE IS DANGER- OUS AND CAN RESULT IN PROPERTY DAMAGE, INJURY OR LOSS OF LIFE.

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 temperature. When you first begin using your Defiant, minimize thermal stress by letting the plates adjust gradually during three or four initial break-in fires follow- ing Steps 1-3 below.

Starting and Maintaining a Wood Fire

Burn only solid wood in the Defiant, and burn it directly on the grate. Do not elevate the fuel. Do not burn coal or other fuels.

The bypass damper must be open when starting a fire or when refueling.

Do not use chemicals or fluids to start the fire. Do not burn garbage. Never use flammable fluids such as gasoline, gasoline type lantern fuel, kerosene, charcoal lighter fluid, naptha, engine oil or similar liquids to start or “freshen up” a fire in this heater. Keep all such liquids well away from the heater while it is in use.
