SAFETY REQUIREMENTS

Recognize safety information. This is the safety-alert symbol _. When you see this symbol on the furnace and in instructions
manuals be alert to the potential for personal injury.

Understand the signal words DANGER, WARNING, or CAUTION. These words are used with the safety-alert symbol. DANGER
identifies the most serious hazards, those that will result in severe personal injury or death. WARNING signifies a hazard that could

result in personal injury or death. CAUTION is used to identify unsafe practices that could result in minor personal injuryor prod uctand
property damage.

Installing and servicing heating equipment can be hazardous due to gas and electrical components. Only trained and qualified person-
nel should install, repair, or service heating equipment.

Untrained service personnel can perform basic maintenance functions such as cleaning and replacing air filters. All other operations
must be performed by trained service personnel. When working on heating equipment, observe precautions in the literature, on tags,

and on labels attached to or shipped with the unit and other safety precautions that may apply.

Follow all safety codes. Inthe United States, follow all safety codes including the current edition National Fuel Gas Code (NFGC) NFPA
No. 54/ANSIZ223.1. In Canada, refer to the current edition of the National Standard Canada CAN/CGA-B149.1 - and .2-M91 Natural

Gas and Propane Installation Codes (NSCNGPI C). Wear safety glasses and work gloves. Have fire extinguisher available during start-

up and adjustment procedures and service calls.

These instructions cover minimum requirements and conform to existing national standards and safety codes. In some instances,
these instructions exceed certain local codes and ordinances, especially those that may not have kept up with changing residential

construction practices. We require these instructions as a minimum for a safe installation.

property damage.

NOTE: This furnace is design certified by the American Gas

Association and the Canadian Gas Association for installation in
the United States and Canada. Refer to the appropriate codes,

along with this manual, for proper installation.

A. The U.S. Consumer Product Safety Commission recom-

mends that users of gas-burning appliances install carbon
monoxide detectors. There can be various sources of car-

bon monoxide in a building or dwelling. The sources could
be gas-fired clothes dryers, gas cooking stoves, water
heaters, furnaces, gas-fired fireplaces, wood fireplaces,

and several other items. Carbon monoxide can cause seri-
ous bodily injury and/or death. Therefore, to help alert

people of potentially dangerous carbon monoxide levels,
you should have carbon monoxide detectors listed by a na-
tionally recognized agency (e.g. Underwriters Laborato-

ries or International Approval Services) installed and

maintained in the building or dwelling (see Note below).

B. There can be numerous sources of fire or smoke in a build-

ing or dwelling. Fire or smoke can cause serious bodily in-
jury, death, and/or property damage. Therefore, in order to

alert people of potentially dangerous fire or smoke, you
should have fire extinguisher and smoke detectors listed

by Underwriters Laboratories installed and maintained in
the building or dwelling (see Note below).

Note: The manufacturer of your furnace does not test any detec-

tors and makes no representations regarding any brand or
type of detector.

• This furnace is NOT approved for installation in mobile

homes, trailers or recreation vehicles.

• Do NOT use this furnace as a construction heater or to heat
a building that is under construction.

Use only the Type of gas approved for this furnace (see
Rating Plate on unit). Overfiring will result in failure of heat
exchanger and cause dangerous operation. (Furnace can

be converted to L.R gas with approved kit.)

• Do NOT use open flame to test for gas leak.

• Ensure adequate combustion and ventilation air is pro-
vided to the furnace.

• Seal supply and return air ducts.

• The vent system MUST be checked to determine that it is
the correct type and size.

• Install correct filter type and size.

• Unit MUST be installed so electrical components are pro-
tected from direct contact with water.

C. To ensure safe and efficient operation of your unit, you

should do the the following:

1. Thoroughly read this manual and labels on the unit.
This will help you understand how your unit operates and

the hazards involved with gas and electricity.

2. Do not use this unit if any part has been under water.
h-nrnediately call a qualified service technician to inspect

the unit and to replace any part of the control system and
any gas control which has been under water.

3. Never obstruct the vent grilles, or any ducts that pro-

vide air to the unit. Air must be provided for proper com-

bustion and ventilation of flue gases.
Carbon monoxide or "CO" is a colorless and odorless gas

produced when fuel is not burned completely or when the

flame does not receive sufficient oxygen.

Installation Requirements

1. Install furnace level.

Install furnace as centralized as practical with respect to the

heat distribution system.

Install the vent pipes as short as practical. (See Gas Vent

Installation section).

Do NOT install furnace directly on carpeting, tile or other

combustible material other than wood flooring.

5. Maintain clearance for fire safety and servicing. A front clear-
ance of 30" (760mm) is minimum for access to the burner,

controls and filter.

Fire Hazard.
Place furnace on noncombustible cement board

or sheet metal on downflow applications.
Failure to install unit on noncombustible cement

board or sheet metal can result in death, personal
injury and/or property damage.

44t 012006 03

6. Use a raised base if the floor is damp or wet at times.

Residential garage installations require:

• Burners and ignition sources installed at least 18" (457mm)
above the floor.

• Furnace must be located or physically protected from pos-
sible damage by a vehicle.

Horizontal FurnaceInstallation

IMPORTANT

NOTE: Inspect unit rating plate to be certain model number be-

gins with "NTP6 or TNE". This identifies unit as horizontally

mountable. If unit does NOT bear this designation, you may NOT
mount this unit horizontally. Horizontal furnace may not be

mounted on its back or front.

The minimum clearances to combustibles MUST be maintained
between the furnace and adjacent construction. As shown in
Figure 3, ONLY the corner of the cabinet is allowed to contact

the rafters. All other clearances MUST be observed as shown in
Figure 1.

If the furnace is to be suspended from the floor joists in a crawl

space or the rafters in an attic, it is necessary to use steel pipe
straps or an angle iron frame to attach the furnace. These straps

should be attached to the furnace with sheet metal screws and to
the rafters or joists with bolts. The preferred method is to use an

angle iron frame bolted to the rafters or joists.

If you purchased a horizontally mountable furnace, it can be

installed horizontally in an attic, basement, crawl space, alcove,
or suspended from a ceiling in a basement or utility room in either
a right or left airflow position. See Figure 3.

Typical Horizontal Installation

2. Combustion&VentilationAir

Thirty inches (30")(760mm) between the front ofthe furnace and
adjacent construction or other appliances MUST be maintained

for service clearance.

Keep all insulating materials clear from Iouvered door. Insulating

materials may be combustible.

It is recommended for further fire protection that cement board or

sheet metal is placed between the furnace and the combustible
wood floor and extend 12" (300mm) beyond the front of the fur-

nace louver door. (This is a recommendation only, not a require-
ment).

This furnace MUST NOT be installed directly on carpeting or tile
or other combustible material other than wood flooring or sup-

ports.

Contaminated CombustionAir

the exposure to chemicals or halogens that may harm the fur-
nace. These instances must use only outside air for combustion.

tion and ventilation air.

Failure to provide adequate combustion and
ventilation air can result in death and/or personal

injury.

Furnaces require ventilation openings to provide sufficient air for

proper combustion and ventilation of flue gases. All duct or open-

ings for supplying combustion and ventilation air must comply
with the gas codes, or in the absence of local codes, the applica-

ble national codes.

When the installation is complete, check that all appliances have
adequate combustion air and are venting properly. See Venting

And Combustion Air Check in "Gas Vent Installation" Section in

this manual.
