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 installation of the furnace for addition of insulation. Some insulations 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 agency.

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.

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 agency 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, the equipment is well supported and there are no signs of deterioration. The manufacturer recommends that main burner, ignition de-vice and controls are inspected by a qualified furnace technician before each heating season.

This gas/electric, heating/cooling unit is designed for outdoor use and can be installed anywhere from grade level to the roof. Electric air conditioning in the summer and gas heating in the winter - all from a single unit.

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 tem-

perature 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.

SPARK TO PILOT IGNITION DEVICE

This unit is equipped with a spark to pilot ignition device. The control is designed to automatically light the burner each time the thermostat “calls” for heat.

Do not attempt to manually light the burners. Personal injury could result.

HEATING

When the thermostat calls for HEAT, the thermostat terminal “W”, “W1” or “W2” is energized, the control board checks for a open pressure switch “PS” and closed limit switches, then energizes the combustion air blower.

After combustion airflow is established, the air proving pressure switch “PS” closes, the ignitor is energized and the pilot valve opens igniting the pilot flame.

The flame rod senses a flame and de-energizes the ignitor opening the main gas valve and the main burners light.

30 seconds after the main burners light the circulating fan is energized at the heating speed.

When the thermostat is satisfied, terminal W is de-energized, deenergizing the ignition system closing the gas valve.

After a 30 second postpurge timing period, the combustion air blower is de-energized and the heat fan off timing begins.

When this field selected heat fan off timing is completed the circulating fan is de-energized.

If the limit switch “LS”, auxiliary limit switch “ALS” or the rollout switch “RS” open, the ignition system is de-energized and the gas valve closes. The combustion blower and the circulating fan are energized.

The combustion blower remains energized for the 30 second postpurge timing period if the limit switch “LS”, auxiliary limit switch “ALS” or the rollout switch “RS” contacts reset (the rollout “RS” and auxiliary limit switch “ALS” must be manually reset). The circulating fan remains energized for the selected heat delay off timing.

Normal operation of the system resumes.

WARNING

Should overheating occur, shut off the manual gas valve external to the appliance before shutting off the electrical supply.

WARNING

Flue hood surface and immediate area is designed to operate at high temperatures during the heating cycle. Special attention must be given to keep all human contact and debris away from this area.

FLUEVENTOUTLET

AIRHOOD

If a call for “COOL” occurs, the circulating fan continues to run at the cool speed.

If a call for “HEAT” occurs, the circulating fan switches to heat speed after a 30 second delay.

When the thermostat ends the call for “FAN”, the thermostat is deenergized, de-energizing the circulating fan.

INPUT

The correct heat capacity of the furnace is regulated by the burner orifices and the gas pressure. The proper orifices are furnished but the gas pressure regulator must be adjusted by the installing serviceman or gas company. This is a “one-time” adjustment.

FOR YOUR SAFETY, READ BEFORE OPERATING

WARNING

Incorrect installation of the flue vent hood could cause personal injury or property damage.

COOLING

When the thermostat calls for “COOL”, the thermostat signals the compressor and outdoor fan to run.

The circulating fan is immediately energized at cooling speed.

When the thermostat is satisfied, the compressor and outdoor fan is de-energized.

After a cool fan off delay timing of 30 seconds the circulating fan is de-energized.

CIRCULATING FAN

When the thermostat calls for “FAN”, the thermostat terminal signals the circulating fan to run at the cool speed.

WARNING

If you do not follow these instructions exactly, a fire or explosion may result, causing property damage, personal injury or loss of life.

A.BEFORE OPERATING, smell all around the appliance area for gas. Be sure to smell around the base of the unit because some gas is heavier than air and will settle in the area.

WHAT TO DO IF YOU SMELL GAS

Do not try to light any appliance.

Do not touch any electrical switch.

Do not use any phone in your building.
