For your safety always turn off both the gas and electrical power before performing service or maintenance on the furnace. 2. Combustion Air Supply A furnace needs an adequate supply of combustion and ventilation air for properand safe operation. Followthe installation instructions included with the furnace to properly vent air to the combustion air inlet and exhaust the products of combustion to the outside from the exhaust vent. If the furnace is operated with a restricted combustion air supply, the pressure switch will open, turning off the gas supply to the burners. (See Figure 1). DO NOT install a jumper wire across this switch to defeat its function. If this switch must be replaced, use only replacement parts authorized distributor. authorized from your • If the furnace is operated with inadequate combustion air supply, the flame roll-out control switch located Failure to prevent products of combustion from being circulated into the living space can create potentially hazardous conditions above the burners may open, turning off the gas supply to the burners. The flame roll-out control is a manually resettable device (See Figure 1 ). DO NOT install a jumper wire across this switch to defeat its function. DO NOT reset the control without identifying and correcting the fault condition which caused the control to trip. If this switch must be replaced, use only authorized replacement parts from your authorized distributor. Air openings in warm air registers, and return air grilles must not be restricted.

Such conditions compounds in the combustion gases. Some examples of these chemicals are chlorine, fluorine, and sulphur. Some common sources of these chemicals are detergents, bleaches, aerosol sprays, cleaning solvents, and a wide variety of commercial and household products. may allow toxic fumes escape into your home: 3. Return Air Supply For upflow models, the return air opening is located in the bottom of the furnace. For downflow models, the return air opening is located at the top of the furnace. The floor or platform on which the furnace is mounted must provide sound physical support of the furnace with no gaps, cracks, or sagging between the furnace and floor or platform. The circulating air ductwork must not be connected to any other heat producing device such as a fireplace insert, stove, etc. Doing so may result in fire, explosion, personal injury, carbon monoxide poisoning, or property damage. • • Obstructions to or restrictions in the vent pipe and/or chimney. • Holes or cracks in the vent pipe. • Visible corrosion pipe. • Horizontal in thevent vent pipes that do not slope upward. If any of the above conditions are found in the vent pipe, call a qualified service technician to install new vent pipe. 5. Maintenance Proper maintenance is most important to achieve the best performance from this furnace and should be performed by a qualified service technician. Follow the maintenance schedule (see Table 1) and the following instructions for years of safe, trouble free operation. Do not place combustible materials on or against the furnace cabinet. Do not store gasoline or any other flammable vapors and liquids in the vicinity of the furnace. Annually inspect the furnace, ductwork, and vent system for signs of physical deterioration. Change or replace the air filters monthly during any period when the circulating blower is operating regularly. Always replace the doors on the furnace after servicing or cleaning/changing the filters. Do not operate the furnace without all doors and covers in place, except to check burner operation. Avoid operating the furnace when windows and doors are open. Be sure that the thermostat is Never operate the furnace without a filter in place. Dust and lint in the return air can build up on the internal components, resulting in a loss of efficiency, equipment damage, and possible fire. properly installed and is not being affected by drafts or heat from lamps orotherappliances. Air Filter(s) --An air filter is supplied with the furnace as shipped from the factory. The filter must be removed and cleaned monthly during the heating season to ensure proper furnace operation. New or newly renovated homes may require more frequent changing until the construction dust has been removed. Always replace the filter with a filter of the same size and type as the filter being removed. Use an air filter in the return air duct to maintain a clean heat exchanger. m Always replace the door(s) on the furnace after servicing or cleaning/ changing the filters. Do not operate the furnace without the door(s) in place. Lubrication -- The bearings in the circulating air blower motors used in these furnaces are pre-lubricated and sealed at the factory. Nofurtheroiling of the bearings is required for the life of the motor. Blower Compartment-The blower compartment should be cleaned monthlyduring the heating and cooling seasons to remove any dirt and lint that may have accumulated in the compartment or on the blower and motor. Buildup of dirt and lint on the blower and motor can create excessive loads on the motor resulting in higher than normal operating temperaturesand possible shortened service life. Burner Maintenance -- Check the burner flames at the start of every heating season. Set the thermostat to a temperature setting above the room temperature. Remove the top door from the furnace and visually inspect the burner through the view hole to make sure that the fla me is drawn into the center of the heat exchanger tube (See Figure 2). In a properly adjusted burner assembly, the flame bends down and to the right at the end of the heat exchanger tube, and the end of the flame will be out of sight around the bend. The flame color should be blue, however some light yellow streaks may occur on the outer _ortions of the flame. Inspect the burners, mounting brackets, and all other parts in the vestibule for signs of deterioration. The burner vestibule should be vacuumed clean and inspected annually.
