HOUR BEFORE BEDTIME Burn the heater at the normal rate for this hour then turn it back to a slower burn just before going to bed This procedure will help drive excess moisture and gases out of wood and minimize creosote buildup during the night This procedure also minimizes the likelihood of backpuffing 7 DO NOT OVERFIRE THE HEATER If any part of the heater or chimney connector becomes red hot turn the thermostat to low and keep the ash and feed doors closed until the heater cools WOOD FACTS The small amounts of wood used in daily fire tending should be kept in a noncombustible container at least 36 inches from the heater Two wood characteristics largely determine the amount of heat energy per cord The first is moisture content Wood must be dry before it will burn properly When first cut its moisture content is high so wood burns poorly and encour ages the formation of creosote It should be cut and stored in a dry place several months preferably a year before it is used Splitting the wood before it is stored reduces its drying time and exposing both ends to the air aids in drying After wood has been stored from six to twelve months it will be dried to a moisture content of 15 to 25 percent This drying results in more even burning and will minimize the buildup of creosote in your chimney 95 11 The second factor in determining heat output is its density or weight per cord With equal seasoning and dryness heavier denser w
