INTRODUCTION

AWARNING

To avoid the possibility of

electrical shock do not
open electrical box pan-

els.

TO OPERATE FURNACE

1. Be sure electrical power to fur-
nace is turned on at the house-

hold service box.

2. Set wall thermostat to the
desired temperature.

3. If furnace is equipped with Air
Conditioning, the System

Switch, located at the wall ther-
mostat, must be turned to

HEAT in order for the furnace
to operate in the heating mode.

The interlock system usually con-
tains a heat-cool switch which

must be turned to either HEAT or
COOL to activate either heating or

cooling operation.
If an interlock system has not been

provided, the electrical supply to
the furnace must be turned OFF at

the household service box, when
the air conditioner is being used.
When operating the furnace, the
electrical supply to the air condi-

tioner must be turned OFE

TO SHUT FURNACE OFF

1. Turn thermostat to its lowest
setting.

NOTE: Furnace will still operate if
room temperature falls below ther-
mostat setting.

2. For complete shut-down turn
off electrical power at the

household service box.

LIMIT CONTROLS

Each element has an automatic
limit switch which is wired into the

circuit and shuts off power to that
element if the heat at that point

exceeds the allowable maximum
heat.

BLOWER REMOVAL

NOTE: Only authorized service

technicians should remove the
blower.

To remove blower from furnace,
turn off power at household service

box, turn furnace circuit breakers
OFF. Disconnect wiring to blower,
and remove five (5) screws holding

blower in furnace and slide blower
out from front of the furnace. See
Figure 1.

Re-install blower in reverse order

when assembling back into fur-

Race.

WARNING

If you have an air condi-
tioner which does not

use the furnace blower
for air distribution and

operates completely
independent of the fur-
nace, the thermostat

system must have an
interlock to prevent the
furnace and air condi-

tioner from operating at
the same time. Such

operation could cause
equipment damage,

energy waste and over-
heating of the home.

SEQUENCE OF

OPERATION

When room thermostat calls for
heat, 24-volt power is supplied to

the heating element switches. As
soon as the first heating element
switch closes, the blower starts
and power is supplied to the first
heating element. Each additional
element is staged on in succes-

sive intervals.
When the room thermostat is satis-

fied and no more heat is required,

the elements sequence off in the
reverse order and the blower will

then turn off.
