WARNING:
The furnace was shipped from the factory
equipped to operate on natural gas. Conversion
to LP/propane gas must be performed by a
licensed HVAC technician using a factory
supplied conversion kit. Failure to use the
proper conversion kit can cause fi re, explosion,
property damage, carbon monoxide poisoning,
personal injury, or death.
INSPECTION
Your furnace and its venting system should be inspected
annually by a licensed HVAC technician. The fi lter should
be inspected at least once a month. See page 7 for Items
that should be inspected by the homeowner.
VENTING SYSTEM
WARNING:
It is imperative to maintain proper operation
of the venting system, including the masonry
chimney if applicable. Insuffi cient venting could
create the production of excessive amounts of
Carbon Monoxide - a colorless, odorless gas that
is a deadly poison that could result in serious
personal injury or death.
SHUTTING DOWN THE FURNACE
Should you ever need to shut down your furnace for service
or maintenance, shut off the gas valve to the furnace
before shutting off the electrical service. Your furnace
may be equipped with one of three types of gas valves.
Remove the door panel from the front of the furnace and
determine which valve type matches your installation in
Figure 1. Either move the switch or turn the knob to the
OFF Position. Additional instructions for shutting down the
furnace can be found on page 7. If your installation has
a manual gas shutoff valve on the gas supply pipe, shut
this off, then shut off the electric to the furnace.
• New or newly renovated homes may require more
frequent changing until the construction dust has
minimized. Filters designed to remove smaller particles
such as pollen, may require additional maintenance.
GAS SUPPLY AND PIPING
This furnace does not have a pilot. It is equipped with an
ignition device which automatically lights the burner.
DO
NOT
light the burner by hand.
IMPORTANT NOTE:
Should the gas supply fail to shut
off or if overheating occurs, shut off the gas valve to the
furnace before shutting off the electrical supply!
WARNING:
All gas piping and shutoff valves must be
installed in compliance with local codes and
utility regulations by licensed installers. DO
NOT attempt to modify, or tap into existing
gas lines yourself. Fire or explosion may result
causing property damage, personal injury or
loss of life. Failure to follow the safety warnings
exactly could result in serious injury, death or
property damage.
