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.
