SYSTEM OPERATION INFORMATION
IMPORTANT: THIS FURNACE WAS
DESIGNED TO OPERATE ON 110-125
VOLTS SUPPLIED BY A
COMMERCIAL POWER UTILITY.
IMPORTANT: CONNECT THIS
FURNACE ONLY TO GAS SUPPLIED
BY A COMMERCIAL UTILITY.
1. Keep the air filters clean. Your
heating system will operate more
efficiently and provide better
heating, more economically.
2. Arrange your furniture and drapes
so that the supply air registers and
the return air grilles are
unobstructed.
3. Close doors and windows. This will
reduce the heating load on your
system.
4. Avoid excessive use of exhaust
fans.
5. Do not permit the heat generated
by appliances such as televisions,
lamps, or radios to influence the
thermostat operation.
6. If you desire to operate your
system with constant air circulation,
consult your thermostat manual or
obtain advice from your HVAC
professional, service agency or the
gas supplier. When continuous fan
is used, the indoor fan will shut-off
on a call for heat. This allows the
heat exchanger to warm up.
7. Do not close off any supply or
return registers.

of the air moving around the thermostat.
Your thermostat may have switches to
select some or all of the following
functions:
