BUILDING CODES AND SAFETY STANDARDS

THE DESIGN OF THIS FURNACE IS NOT CERTIFIED FOR USE IN MOBILE HOMES, TRAVEL
TRAILERS OR CAMPERS. THIS FURNACE MUST BE PROPERLY VENTED TO THE OUTSIDE
FOR SAFE OPERATION. DO NOT OPERATE THIS FURNACE WITHOUTAN ADEQUATE VENTING
SYSTEM.

THE DESIGN OF THIS APPLIANCE COMPLIES WITH ANSI Z21.48.
THE SECTIONS OF THIS MANUAL PERTAINING TO VENTING AND GAS PIPING PROVIDE ONLY

NATIONAL FUEL GAS CODE ANSI Z223.1.

IMPORTANT GENERAL INFORMATION

Read these instructions completely before beginning the installation and use these instructions as aguide during the installation.

Your furnace has been carefully designed and constructed. The design of this furnace has been tested according to the
standards set by the American National Standards Institute, and the design has been certified by the American Gas Association

as conforming to these standards. Care has been taken to assure that your furnace will operate safely, efficiently, and
reliably, but your furnace must be properly installed. Only a licensed or otherwise qualified gas equipment installer should

install this furnace, the vent serving this furnace, and the gas piping. Installation procedures should comply with these
instructions and the latest edition of the American National Standard National Fuel Gas Code Z223.1. You should also refer

to any local codes or ordinances which may apply. Improper installation of the furnace, vents or gas piping, can subject you

Safety Rules

WARNING 4. LOCATE the furnace out of traffic patterns as much as

READ THESE RULES AND THE INSTRUCTIONS

CAREFULLY. FAILURE TO FOLLOW THESE

RULES AND INSTRUCTIONS COULD CAUSE A
MALFUNCTION OF THE FURNACE. THIS COULD
RESULT IN DEATH, SERIOUS BODILY INJURY,

AND/OR PROPERTY DAMAGE.

possible with a minimum of 6" clearance from all
combustible walls and 15" on two adjoining sides of the
grille for passage.

5. BE SURE to provide for adequate combustion and
ventilation air. The flow of this air to the furnace must not
be blocked.

INSTALLATION MUST CONFORM TO LOCAL CODES. IN

THE ABSENCE OF LOCAL CODES, INSTALLATION MUST

CONFORM WITH THE NATIONAL FUEL GAS CODE, ANSI
Z223.1.

INSTALLATION AND REPAIR SHOULD BE DONE BY A
QUALIFIED SERVICE TECHNICIAN. THE CLEANED
FURNACE SHOULD BE INSPECTED BEFORE USE AND

AT LEAST ANNUALLY BY A PROFESSIONAL SERVICE

TECHNICIAN. MORE FREQUENT CLEANING MAY BE
REQUIRED DUE TO EXCESSIVE LINT FROM SOME

CARPETING, BEDDING MATERIAL, ETC. IT IS
IMPERATIVE THAT CONTROL COMPARTMENTS,

BURNERS AND CIRCULATING AIR PASSAGEWAYS OF
THE FURNACE BE KEPT CLEAN.

YOUNG CHILDREN SHOULD BE CAREFULLY
SUPERVISED WHEN THEY ARE IN THE SAME ROOM

WITH THE FURNACE.

ANY SAFETY SCREEN, GUARD OR PARTS REMOVED
FOR SERVICING AN APPLIANCE MUST BE REPLACED

KEEP THESE INSTRUCTIONS

FOR FUTURE REFERENCE

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 ofthehouse (see figure 1). Besuretheseopenings

are located where the air can flow to the furnace and is not
likelyto 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.

Continued safe and satisfactory performance ofthis furnace

requires, but is not limitedto,periodicexaminationof 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 productsto the
outside, must be replaced before the furnace isoperated. A
completedescriptionof theventing requirementsiscontained
inthe "Venting And Chimney Requirements" sectionofthese

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. Ifyou 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•

Locating Floor Furnace

Consider the following points before attempting to install the
furnace:

1. To achieve the best results from this furnace, it must be
located in an area that will provide good circulation of air

to adjacent areas that need to be heated.

2. Warm air will rise from the furnace and travel to other areas
only through open doorways, and that air must return to

the furnace to be reheated.

LIVING ROOM

BEDROOM

AIR -

3. Insmall homes, one unit centrally located may be sufficient
to meet the heating requirements, but it is impractical to

attempt to use this furnace where heat must travel through

more than one doorway before reaching an area where
heat is desired. A typical installation of a single unit in a
small home is shown by Figure 2.

4. In larger homes, it may be necessary to use two or more
units to provide sufficient heat distribution. It is often better
to use two small furnaces rather than one large one.

5. If there is a difference in the floor level between two rooms
to be heated, the furnace should be located in a room with

the lower floor.

6. The flow of heat to various areas within the home can be
effectively regulated by the opening and closing of doors.

CLEARANCES

1. Minimum clearance between the floor furnace and
adjacent walls - 6".

2. Minimum clearance between furnace and doors,

draperies or other combustible materials within the

home - 12".

3. Minimum space required along two sidesof the furnace
to allow persons to walk around the furnace - 15".

The thermostat should be located on an interior wall far
enough away from the furnace to prevent itfrom being heated

directly by the furnace. Select a location in the area most
frequently used or best situated to control the temperature of
the entire house. Avoid locations where the thermostat might

be subjected to drafts from windows, doors, stairways, etc.,
or from other devices such as cooking ranges, fireplaces,
television, etc. Place the thermostat about five (5) feet above
the floor. Do not select a location that will require more than

25 feet of wire between the furnace and the thermostat. Do
not install the thermostat in an area which can be isolated
from the furnace by a door.

LOCATION NOTE

Replacement floor furnaces of the same or lesser
Btu/h input rating may be installed in the same location
as the replaced furnace when such replacement does

not create an unsafe condition.

After you have selected a location that will provide the
necessary clearances and air circulation, check beneath the

house to be sure the clearances between the furnace and
the ground, as specified by Figure 1, can be obtained. It is

permissable to dig a shallowpit, as shown in Figure1, but a
pipe or trench should be provided to drain away any water

that may seep intothe pit. Ifthe depth of the pitmust exceed

12", or ifwater seepage is likely,a watertight pit ofgalvanized
steel, copper, concrete or other suitable material shouldbe

constructed and anchored intoplaceto preventitfrom floating.
The sides of this pan should extend four inches above the

ground. The clearances between the upper rim of the pan
and the furnace should be no less than those specified in

Figure 1.

The width, length and depthof each furnace model is shown

in Figure 6.
