After the furnace has been lit and adjusted, you
need only to set the thermostat to the temperature
you want. The thermostat will turn the furnace on
and off as needed to keep that temperature.
The furnace works like this:
1. Thermostat turns on the main burners.
2. Heat builds up in the furnace and starts the fan.
The heated air comes out the front panel louvers at
floor level.
3. When the thermostat setting is reached, it shuts
off the main burners.
4. The fan runs until the heat is removed from
furnace, then turns off.
The fan has two speeds. It will start on low speed. It
may switch to high speed as the air temperature
increases. This is automatic. No manual switching is
needed.
LIMIT CONTROL
The furnace has a limit switch which will prevent
overheating, if anything should back the ftow of air
through the furnace, the switch will turn the main
burners off. This switch cannot be adjusted.
MANUAL SELECTOR SWITCH
The furnace has a manual fan switch on the control
panel. This switch must be set at "AUTOMATIC" for
heating. If not, the furnace will not work.
Set the fan switch at the "SUMMER" position if you
want only the fan to run.

you set the burners for high or medium heat output.
