Use the Air Control Settings that Work Best for You

No single air control setting will fit every situation. Set- tings will differ depending on the quality of the fuel, the amount of heat desired, and how long you wish the fire to burn.

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.

Too much draft may cause excessive temperatures in the Intrepid II, 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. A sign of inad- equate draft is 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 outdoors to the stove. In fact, in some areas provisions for outside combustion air are required in all new construction.

Your Intrepid II will accept a duct carrying outside air for combustion.

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 some time to determine the amount of heat and the length of burn you should expect from various settings. Please read the Draft Management section beginning on Page 18 for more information on how installation features affect draft.

Most installations do not require a large amount of com- bustion 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.

Before you start using the stove, please read the Draft Management section starting on Page 18 to see how the features of your installation will affect the stove’s performance. You and the stove are parts of a system, and other parts of the system have a strong effect on operation; you may need to vary your firing technique to get the performance you want.

How to Build a Wood Fire

and Keep it Going

An Intrepid II leaves the factory with the combustor installed.

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.

High-Efficiency Wood Burning

with Catalytic Combustion

The catalytic combustion system in your Intrepid II produces the best conditions for secondary combustion.

When the stove damper is closed, smoke goes through the catalytic element, burning at temperatures of

260-315° C (500-600° F), half the temperature normally needed for unaided secondary combustion.

The catalytic element is a ceramic “honeycomb” coated with a noble metal, usually platinum. The element is in the secondary combustion chamber, made of a spe- cial high-temperature insulating refractory material. The chamber provides the correct environment neces- sary for secondary combustion of the fuel (smoke).

Closing the damper may also reduce draft. Closing the damper too soon may put out the fire or deactivate the combustor. Close the damper only when the fire is well established. When starting a fire, wait until there is an ember bed of at least 76 - 102 mm (3-4”) before closing the damper.

Never kindle a fire with colored paper or paper that has colored ink or a glossy surface, and never burn treated wood, garbage, solvents, or trash. All of these may poison the catalyst and prevent it from operating properly. Never burn cardboard or loose paper except for kindling purposes. Never burn coal; doing so can produce soot or large flakes of char or fly ash that can
