ture level in your home more evenly balanced. It also continuously ﬁlters the indoor air.

NOTE: Constant low-speed blower operation can also be achieved by turning on the constant blower rocker switch located on top of unit. Regardless of room ther- mostat setting, blower will run continuously in low speed to provide constant air circulation. If constant blower rocker switch is turned off, room thermostat will control blower operation.

SHUTTING DOWN YOUR FURNACE

Should you need to shut down your furnace for service or maintenance, you will need to turn the furnace off. The following procedures must be followed:

1.Set the thermostat to the lowest setting. (See Fig. 8.)

PERFORMING ROUTINE

MAINTENANCE

With proper maintenance and care, your furnace will operate economically and dependably. Instructions for basic maintenance follow. However, before beginning maintenance, follow these safety precautions:

!WARNING

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury due to electrical shock.

Turn off all electrical power to furnace before performing any maintenance or service on unit.

2.Turn off all electrical power to the appliance. (See Fig. 9.)

3.Close the oil supply valve. (See Fig. 10.)

4.If applicable, turn off water supply to humidiﬁer.

5.If furnace blower will be necessary for cooling sys- tem, remember to turn electric power back on when needed for air conditioning.

6.If the furnace is being shut down because of a mal- function, call your dealer as soon as possible.

ALWAYS KEEP MAIN OIL VALVE TURNED OFF IF BURNER IS SHUT DOWN FOR AN EXTENDED PERIOD OF TIME.

!CAUTION

CUTS AND ABRASION HAZARD

Failure to follow this caution may result in mi- nor personal injury.

Although special care has been taken to mini- mize sharp edges, be extremely careful when handling parts or reaching into the furnace.

FILTERING OUT TROUBLE

Dirty air ﬁlters will cause a loss of airﬂow in your duct system. When excessive loss of airﬂow occurs, the fur- nace may cycle on its safety controls. If this condition is left unattended, the furnace will eventually lock out. It is recommended that the furnace air ﬁlters be checked every 3 or 4 weeks and cleaned or replaced as necessary.

!CAUTION

UNIT OVERHEAT HAZARD

Failure to follow this caution may result in damage to the furnace blower motor, over heat the heat exchanger and reduce the effi- ciency.

Never operate your furnace without the air fil- ters in place.

The air ﬁlters are located in the blower compartment installed in an internal ﬁlter rack which is provided as standard equipment with furnace. (See Fig. 2.) To
