KEEP THESE INSTRUCTIONS
All furnaces require a supply of oxygen for combustion. To
assure thisfurnace receives the necessary oxygen, two free
air openings of at least one square inch for each 1,000 BTU
per hour input rating of the furnace must be provided in the
foundation of the house (see figure 1). Be sure these openings
are located where the air can flow to the furnace and is not
likely to be blocked.
This furnace is equipped with a temperature limit control
that limits the register temperature under normal conditions
of operations. This control may be overidden under unusu-
al cimumstances, such as extremely cold weather, to allow
more heater output from this heater. A complete explana-
tion of the operation of this control is contained in the
"Operating The Furnace" section of these instructions.
An inspection of the furnace and attached systems should
be performed at least once each year by a qualified service
technician. More frequent inspections are advisable if the
furnace is installed or operated in a manner that might cause
the accumulation of dust or dirt in the furnace or the failure of
component parts more rapidly than would normally be
expected. Keep all combustible materials, gasoline and other
flammable liquids or vapors away from this furnace, and be
sure that combustion and ventilation air openings supplying
this furnace are kept clear at all times.
FOR FUTURE REFERENCE
Continued safe and satisfactory performance of this furnace
requires, but isnot limitedto, periodicexamination of the vent
system, pilot flame, combustion chamber, liners and gas
supply lines and periodic cleaning of the burner air intake,
pilot and control areas. The venting system, including the
factory provided drafthood and all other parts of the vent,
must be inspected periodicallyfor indicationsof failure, such
as loose joints, rusting components or broken parts. Any
defective or damaged part, which does not provide a
continuous conduit to carry the combustion products to the
outside, must be replaced before the furnace is operated. A
complete descriptionof the venting requirementsiscontained
inthe "Venting And Chimney Requirements" sectionof these
instructions.
This furnace is designed to burn only the type gas that is
indicated on the rating plate, visible on the bracket directly
beneath the floor grille. Do not attempt to use this furnace
with any other type gas. If you are not sure what type gas is
available in your locality, obtain this information from your
local gas supply company.
The pilotand control system of this furnace will automatically
stop the gas flow to the pilot burner and main burner if the
pilot flame is extinguished. This system also generates the
electricity required to operate the thermostat system. Since
no electrical power is required from any other source, this
furnace will continue to operate during a power outage•
