SAFETY INFORMATION

FOR YOUR SAFETY

• Make sure that the furnace area is clear and free of combustible materials, gasoline and other flammable vapors and liquids.

• Be sure the furnace is free and clear of insulating material. Examine the furnace area after installation of the furnace or the installation of additional insulation. Some types of insulation are combustible.

• For proper operation of this furnace, air for combustion and ventilation is required. Make sure that these openings are not obstructed.

• For lighting or shutting down this furnace, refer to the lighting instructions provided adjacent to the burners and also located in this manual.

• A blocked vent roll-out switch is provided in the burner compartment. This switch is a manual reset. If the furnace fails to operate, contact a qualified service technician.

• Should the gas supply fail to shut off or if overheating occurs, shut off the gas valve to the furnace before shutting off the electrical supply. Then call a qualified service technician.

SYSTEM OPERATION

THERMOSTATS

Set your thermostat for either heating or cooling then set it for the desired temperature. DO NOT MOVE THE THERMOSTAT RAPIDLY ON AND OFF, OR BACK AND FORTH FROM HEAT TO COOL. THIS COULD DAMAGE YOUR EQUIPMENT.

Always allow at least 5 minutes between changes. Find the temperature that is most comfortable to you, and then LEAVE YOUR THERMOSTAT ALONE. (Exception is for night or vacation “set back” to conserve energy).

Manually moving the thermostat up or down will not speed up temperature changes in your rooms. This only causes the thermostat switch to function at your command rather than responding to room temperature.

Heat generated by devices other than the furnace may interfere with thermostat performance. Therefore, lamps, radios, television sets, etc. should not be placed near the thermostat.

• Do not use this furnace if any part has been under water. A flood-damaged furnace is extremely dangerous. Attempts to use the furnace can result in fire or explosion. A qualified service technician should be contacted to inspect the furnace and to replace all gas controls, control system parts, electrical parts that have been wet or the furnace if deemed necessary.

• Determine the integrity of the installation regarding the flue gas vent, the return and supply air duct. Confirm the equipment is well supported and there are no signs of deterioration. The manufacturer recommends that main burner, ignition device and controls are inspected by a qualified service technician before each heating season.

FIGURE 1 - TYPICAL THERMOSTAT

INTERMITTENT IGNITION DEVICE

Your unit is equipped with a cycling pilot burner. It has a Pilot Relight control designed to automatically light the pilot burner each time the thermostat “calls” for heat.

This furnace is equipped with an intermittent pilot and automatic re-ignition system. Do Not attempt to manually relight the pilot. Personal injury could result.

When the thermostat calls for heat, pilot gas is supplied and at the same time, sparking occurs to light the pilot gas. With the pilot lit, the flame sensor rod closes a circuit to the ignitor control which then opens the gas valve to admit main burner gas.
