14100748FRESH AIR FORCOMBUSTIONANDVENTILATIONWARNINGThis heater must have fresh air for proper operation. Ifnot, poor fuel combustion and improper venting of fluegases will result. Carbon monoxide poisoning frombacked-up flue gases could occur. Read the followinginstructions to insure proper fresh air for this and otherfuel-burning appliances in your home.Today’s homes are built more energy efficient than ever. New materials, increasedinsulation, and new construction methods help reduce heat loss in homes. Homeowners weather strip and caulk around windows and doors to keep the cold air outand the warm air in. During heating months, home owners want their homes asairtight as possible.While it is good to make your home energy efficient, it is not good to make it tooairtight. Your home needs to breath. If your home is too airtight, fresh air has littlechance of entering in. This could be dangerous if you have fuel-burning appliances.These appliances need fresh, outside air for proper combustion and ventilation.Exhaust fans, fireplaces, clothes dryers, and fuel-burning appliances draw air fromthe house to operate. This heater is a fuel-burning appliance. It uses air from insidethe house for combustion. It also uses this air as a draft for venting. This draft airhelps move combustion gases through the vent pipe to the outdoors. If your houseis too airtight, there is not enough fresh air for these items to use. Fresh air maydraw back into the house through venting flues and chimneys. This will keep fuel-burning appliances from venting properly. This may cause them to release poison-ous carbon monoxide gas into your home. It is very important to provide enoughfresh air to run all fuel-burning appliances.DANGERCarbon monoxide poisoning may lead to death!Carbon monoxide is a colorless, odorless gas. Early signs of carbon monoxidepoisoning resemble the flu, with headaches, dizziness, and/or nausea. If you havethese signs, the heater may not be operating or venting properly. Get fresh air atonce! Have heater or heater venting system serviced. Some people are moreaffected by carbon monoxide than others. These include pregnant women, personswith heart and lung disease and anemia, those under the influence of alcohol, andthose at high altitudes.
