WARRANTY AND
RESPONSIBILITIES
It is the sole responsibility of the home
owner to make certain that the gas
furnace has been correctly set up and
converted to the proper fuel (Propane
or Natural gas) and adjusted to oper-
ate properly.
The manufacturer warrants the fur-
nace to be free from defects in materi-
al or workmanship for the stated time
in the warranty agreement (see war-
ranty certificate packed with the fur-
nace).
However, the manufacturer will not be
responsible for any repair costs to
correct problems due to improper
set--up, improper installation, furnace
adjustments, improper operating pro-
cedure by the user, etc.
Some specific examples of service
calls which cannot be included in war-
ranty payments are:
1. Converting the furnace to use
another type of gas.
2. Correcting faulty duct work in the
home.
3. Correcting wiring problems in the
electrical circuit to the furnace.
4. Resetting circuit breakers or oth-
er switches.
5. Adjusting the burner air shutter or
service calls made to correct
problems caused by improper air
adjustment.
6. Correcting problems caused by
improper gas supply pressure to
the furnace.
7. Instructional training on how to
light and operate furnace.
8. Furnace problems caused by in-
stallation of air conditioner, heat
pump, or other air quality device
which is not approved.
9. Problems caused by improper in-
stallation of the furnace flue as-
sembly (roof jack).
10. Adding a roof jack extension
because of unusual wind condi-
tions or snow conditions.
11. Adjusting or calibrating the ther-
mostat.
12. Construction debris which has
fallen into the flue or combustion
air openings.
You should establish a firm under-
standing of these responsibilities with
your manufactured housing dealer,
service company or gas supplier so
there will be no misunderstanding at a
later time.
GAS SUPPLY
The gas supply to your home will ei-
ther be Natural Gas or Propane gas
(bottle gas). Your furnace will be fac-
tory equipped to operate on only one
of these two different gases.
A small metal tag secured to the fur-
nace next to the gas valve will specify
the type of gas your furnace is
equipped to use.
If the gas is different from that speci-
fied on the metal tag, the furnace can
be converted by following the instruc-
tions on the furnace safety label
inside lower front panel. Parts for con-
version are contained in the small
cloth bag attached to the gas valve.
Be sure the proper size orifice is used,
as specified on the furnace name
plate.
The furnace must be con
Ć
verted by a qualified techni
Ć
cian. Improper conversion
can cause unsafe operation,
explosion, and/or fire or as
Ć
phyxiation.
Natural Gas Operation
The furnace is designed for 7” W.C.
inlet pressure. Pressure is reduced to
3 1/2” W.C. by the pressure regulator
in the gas valve.
Propane Gas Operation
Inlet pressure to the gas valve must
be 11”W.C. When properly converted
to Propane gas, the pressure is regu-
lated at 10” W.C.
SAFETY INFORMATION
For your safety read before lighting.
A. The first lighting of the furnace af-
ter any home setup must be per-
formed by a qualified service
technician.
B. If this appliance has a pilot that
must be lit by hand, follow these
instructions exactly.
C. BEFORE LIGHTING smell all
around the furnace for gas. Be
sure to smell next to the floor be-
cause some gas is heavier than
air and will settle on the floor.
WHAT TO DO IF YOU SMELL GAS:
D Do not try to light any appliance.
D Do not touch any electric switch
and do not use any phone in your
building.
D Immediately call your gas suppli-
er from a neighbor’s phone. Fol-
low the gas supplier’s instruc-
tions. If you cannot reach your
gas supplier, call the fire depart-
ment.
D. Use only your hand to push in the
gas control lever. Never use
tools. If the lever will not push in
by hand, don’t try to repair it. Call
a qualified service technician.
Force or attempted repair may re-
sult in a fire or explosion.
E. Do not use this furnace if any part
has been under water. Immedi-
ately call a qualified service tech-
nician to inspect the furnace and
to replace any part of the control
system and any gas control
which has been under water.
