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.

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. (Fig. 24)

ST523

Fig. 24 Take temperature readings with the thermometer located in the middle of the griddle.

For example, when the thermometer registers at least 230° C (450° F) 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 opera- tion. Please review the draft management information on Page 23 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’s 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 to operation:

•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 315-400° C (600-750° F) indicate high heat output. Operating your Encore 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. Refer to Page 23 for details on how the installation af- fects performance.

Too much draft may cause excessive temperatures in the Encore, 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.

In some areas provisions for outside combustion air are required. Refer to section 2 of Document J which requires an outside air vent for appliances with power outputs over 5 kW. Always refer to national and local codes to determine your specific requirements.

Your Encore will accept a duct to deliver 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 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.
