Room Thermostat Requirements
When selecting thermostat location, consider-
ation must be given to the following:
1.
Locate the thermostat approximately five
feet above the floor in a location accessible
for wiring and setting, preferably in a living
or adjoining room.
2.
Locate on an inside wall.
3.
Do not locate where influenced by abnor-
mal heat, such as from sunlight, radio,
T.V., or lamps.
4.
Do not locate where influenced by abnor-
mal cold, such as on an outside wall, on a
wall separating an unheated room,
near drafts from stairwells or doors, or
close to windows.
5.
Do not locate where air circulation is poor,
such as behind open doors, in corners or
alcoves, or close to furniture.
The heat anticipator of the thermostat should be
adjusted to .4 amps for power oil models, and
.9 for power gas direct ignition models.
Room Thermostat Connections
1.
Run R and W from the thermostat to the
burner compartment.
2.
Connect R to one of the low voltage
terminals on the burner.
3.
Connect W to the other low voltage terminal
on the burner.

Fan and Limit Settings
!
CAUTION:
When adjusting the fan setting levers,
hold the scaleplate dial to keep it from
turning and straining the sensing ele-

The FAN ON lever controls the temperature at
which the blower energizes. This lever can be
adjusted through a range of 15
o

OFF setting to 30
o
F below the LIMIT OFF
setting. The recommended factory setting is
110
o
F.
The FAN OFF lever controls the temperature
at which the blower is to stop to prevent the
circulation of cool air. The recommended factory
setting is 90
o
F.
The LIMIT OFF lever is a safety stop. This lever
should not be adjusted or tampered with for any
reason. The factory setting is 160
o
