1. Installation

Installation or repairs made by unqualified persons

can result in hazards to you and others. Installation

MUST conform with local codes or, in the absence of local codes, with codes of all governmental authorities having jurisdiction.

The information contained in this manual is

intended for use by a qualified service technician who is experienced in such work, who is familiar with all precautions and safety procedures

required in such work, and is equipped with the

proper tools and test instruments.

Failure to carefully read and follow all instructions

in this manual can result in furnace malfunction,

property damage, personal injury and/or death.

NOTE: Refer to the appropriate codes, along with this manual, for proper installation.

water heaters, furnaces, gas-fired fireplaces, wood fire- places, and several other items. Carbon monoxide can cause serious bodily injury and/or death. Therefore, to

help alert people of potentially dangerous carbon monox- ide levels, you should have carbon monoxide detectors listed by a nationally recognized agency (e.g. Underwrit- ers Laboratories or International Approval Services) installed and maintained in the building or dwelling (see

Note below).

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 mo- bile 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.

• It is the suggestion of this manufacturer to install fire and carbon monoxide detectors.

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. Immediately 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.

Freezing Temperatures and Your Structure

Freeze warning.

Turn off water system. If your unit remains shut off during cold weather

the water pipes could freeze and burst, resulting in serious water damage.

Safety Rules

Your unit is built to provide many years of safe and dependable service providing it is properly installed and maintained. Howev-

er, abuse and/or improper use can shorten the life of the unit and create hazards for you, the owner.

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

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

carbon monoxide in a building or dwelling. The sources could be gas-fired clothes dryers, gas cooking stoves,

Your unit is equipped with safety devices that may keep it from operating if sensors detect a bnormal conditions such as clogged exhaust flues.

If the structure will be unattended during cold weather you should take these precautions.

1. Turn off main supply water into the structure and drain the water lines if possible. Open faucets in appropriate areas.

2. Have someone check the structure frequently during cold weather to make sure it is warm enough to prevent pipes

from freezing. Suggest they call qualified service agency, if required.

Location and Clearances

Poison carbon monoxide gas hazard. If this furnace is replacing a previously

common-vented furnace, it may be necessary to

resize the existing vent line and chimney to prevent oversizing problems for the other remaining appliances(s). See applicable codes

and Venting and Combustion Air Check in Gas

Vent Installation section.

Failure to properly vent this furnace or other appliances can result in property damage, personal injury and/or death.

combustible material other than wood flooring.

Maintain clearance for fire safety and servicing. A front clearance of 30" (760mm) is minimum for access to the

burner, controls and filter.

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

7. Residential garage installations require:

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

[33

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

Horizontal Furnace Installation

IMPORTANT

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

gins with "NTC6 or GNE', 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,

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 2.

Thirty inches (30") (760mm) between the front of the 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.

The horizontal furnaces may be installed directly on combustible

wood flooring or supports, however it is recommended for further

fire protection that cement board or sheet metal is placed be- tween the furnace and the combustible wood floor and extend

12" (300mm) beyond the front of the furnace louver door. (This is a recommendation only, not a requirement).

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

Figure 2 Typical Horizontal Installation

The following minimum clearances to combustibles MUST be maintained between the furnace and adjacent construction. As

shown in Figure 1, ONLY the corner of the cabinet is allowed to contact the rafters Figure 2. All other clearances MUST be ob- served 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 the furnace is to be installed ground level in a crawl space, con- sult local codes. A concrete pad 1" to 2" (25 to 50ram) thick is rec-

ommended.

Pressure Switch Relocation

If the furnace is installed in a right to left airflow position (left side of furnace facing down), the pressure switch will remain in the

same position as installed by the factory (see Figure 3). If the furnace is installed in a left to right airflow position (right side of furnace facing down), the pressure switch MUST be relocated to the left side of the furnace using the holes provided in the top pan-

el. Position the pressure switch in the same orientation as the original location. To prevent possible kinking of the pressure

switch hose, trim the hose to remove excess.

Note: Care MUST be taken not to cut the tube too short.

2. Combustion & VentilationAir

Poison carbon monoxide gas hazard. Use methods described here to provide

combustion and ventilation air.

Failure to provide adequate combustion and

ventilation air can result in personal injury

and/or death.

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 this manual.

NOTE: A confined space is defined as an area with less than 50 cubic feet(1.4m 3) per 1,000 BTUH input rating for all gas ap- pliances installed in the area.

Air Openings and Connecting Ducts

1. Total input rating for all gas appliances MUST be considered when determining free area of openings.

2. Connect ducts or openings directly to outside.

3. When screens are used to cover openings, the openings MUST be no smaller than 114" (6mm) mesh.

4. The minimum dimension of rectangular air ducts MUST NOT be less than 3" (75mm).

5. When sizing grille or louver, use the free area of opening. If free area is NOT stamped or marked on grill or louver, as-

sume a 20% free area for wood and 60% for metal.

Requirements

1. Provide confined space with sufficient air for proper com- bustion and ventilation of flue gases using horizontal or ver- tical ducts or openings.
