GAS SHUTOFF
Should overheating
occur, or the gas supply
fail to shut off, shut off
the manual gas valve to
the furnace and allow
blower to run until fur-
nace cools down and
blower shuts off before
shutting off the electrical
supply
The furnace gas valve is equipped
with a manual gas shutoff. To turn
off gas to the furnace, move the
lever on the gas valve to the =OFF"
position.
The furnace installation shouldalso
have a manual shutoff valve in the
gas piping to the furnace, similar to
what is shown in Figure 3. To turn
off the gas to the furnace, use a
wrench and turn the knob or lever
so that it is pointing 90 degrees
from the gas pipe, as shown in Fig-
ure3.

Set the room thermostat at the
desired room temperature. Great-
est comfort will be achieved when
the setting is not changed fre-
quently.
For energy conservation and econ-
omy it is recommended that the
thermostat be set at 68 ° for heating
and 80 ° for cooling.
For Heating with Air Condition-
ing Applications - Set heat/cool
switch to =HEAT" position and set
fan switch to "AUTO" position.
OBSERVING BURNER
OPERATION
1. Observe bumer to make sure it
ignites. Observe color of flame.
On natural gas the flame will
burn blue with appreciably yel-
low tips. On Propane gas a yel-
low flame may be expected. If
flame is not the propercolor
cell a qualified serviceman for
service.
2. Let furnace heat until blower
cycles on.
3. Turn thermostat down.
4. Observe burnerto make sure it
shuts off.
5. Let the furnace cool and
blower cycle off.
If any abnormalities are observed
when checking for correct opera-
tion, such as burner failing to ignite
or to turn off, sooty flame, etc., cell
your nearest authorized service
technician as shown in the Service
Center List included in the home
owner envelope.
IF FURNACE FAILS TO
OPERATE PROPERLY
1. Check setting of thermostat-
and positionof heat/cool switch
if air conditioning is installed. If
a set-back type thermostatis
employed be sure that the ther-
mostat is in the correct operat-
ing mode.
2, Check to see that electrical
power is "ON".
3. Check to see that the lever or
switch on the gas control valve
is in the full "ON" position.
4. Make sure filters are clean,
return grilles are not
obstructed, and supply regis-
ters are open.
5. Be sure that furnace flue piping
is open and unobstructed.
If the cause for the failure to
operate is not obvious, do not
attempt to service the furnace
yourself. Call a qualified service
agency or your gas supplier.
PERIODIClNSPECTION
AND MAINTENANCE BY
HOMEOWNER
It is recommended that the home-
owner or user make an inspection
of the furnace at least every 90
days, or more often if desired. It is
also recommended that a qualified
service agency inspect the furnace
before each operating season the
furnace is used, both heating and
air conditioning, and at any time
that there is an indication of mal-
function. The owner/user should
not attempt to disassemble the fur-
nace unless experienced and qual-
ified to do so.
CAUTION
FOR SAFETY- Turn off
electrical power to fur-
nace before performing
service such as clean-
ing filters.
Filters
It is very important that filters in
your furnace or air conditioning
system be replaced frequently.
Clean filters not only provideadded
comfort and a more healthful envi-
ronment, but also allow the system
to operate more efficiently. Check
filtersevery two or three weeks.
