Liquid gas from an over filled tank can be forced
•
through the pressure regulator resulting in high pressure
gas escaping, causing fire/explosions.

Improper installation, adjustment, alteration, service or
•

injury or loss of life. Refer to the installation instructions
and/or owners manual provided with this appliance.
Installations, repairs and preventive maintenance

Listed below are several safety related items that you the (owner)
should follow each heating season to assure continued safe operation
of the furnace. A periodic inspection of the furnace by a qualified
service agent is also recommended.
Inspect furnace venting. Venting must be free of obstructions,
•
void of soot and properly terminated to the atmosphere. Make
sure that the vent assembly is positioned tight against out door
screens on 8500 and 8900 series.
Periodically inspect the vent for obstructions or presence of soot.
•
Soot is formed whenever combustion is incomplete. This is your
visual warning that the furnace is operating in an unsafe manner.
If soot is present, immediately shut furnace down and contact
your dealer or a qualified service person.
Keep furnace clean. More frequent cleaning may be required due
•
to excessive lint from carpeting, bedding material, pet hair etc. It
is imperative that control compartments, burners and circulating
air passageways of the appliance be kept clean and
unobstructed.
The motor is permanently lubricated and requires no oiling.
•
Keep the furnace area clear of any combustible materials,
•
gasoline, or other flammable vapor and liquids.
Before operating furnace, check the location of the furnace vent to
•
make sure it will not be blocked by the opening of any door on the
trailer. If it can be blocked, do not operate the furnace with the
door open.
Do not restrict the flow of combustion air or the warm air
•
circulation to the furnace. To do so could cause personal injury
and/or death.
Never operate the furnace if you smell gas. Do not assume that
•
the smell of gas in your RV is normal. Any time you detect the
odor of gas, it is to be considered life threatening and corrected
immediately. Extinguish any open flames including cigarettes and
evacuate all persons from the vehicle. Shut off gas supply at LP
gas bottle. (See safety notice in this manual).
Immediately shut furnace down and call a service agency if
•
furnace cycles erratically or delays on ignition.
Never attempt to repair the furnace yourself. Seek the help of a
•
qualified service person.
Never restrict the ducting installed by your trailer manufacturer.
•
To do so could cause improper furnace operation.
Do not install air boosters in the duct system. Such devices will
•
cause the furnace to cycle on limit and to have erratic sail switch
operation.
Clothing or other flammable material should not be placed on or
•
near the appliance.
WARNING
WARNING
Always follow the Operating Instructions. Do not deviate from the
•
step-by-step procedures.
When considering add-on rooms, porch or patio, attention must
•
be given to the venting of our furnace. For your safety, do not
terminate furnace vent inside add-on rooms, screen porch or onto
patios. Doing so will result in products of combustion being vented
into the room or occupied areas.
In any installation in which the vent of the appliance can be
•
covered due to the construction of the RV or some special feature
of the RV such as slide out, pop-up etc. Always insure that the
appliance cannot be operated by setting the thermostat to the
positive "OFF" position and shutting off all electrical and gas
supply to the appliance. Never operate furnace with vent covered.
