Introduction

The 4-way multipoise Category IV condensing furnace is CSA design-certified as a direct (2-pipe) or non-direct vent (1-pipe)

furnace. (See Figure 3) The furnace is factory-shipped for use with natural gas. The furnace can be converted in the field for

use with propane gas when a factory-supplied conversion kit is used. Refer to the furnace rating plate for conversion kit

information. Single Stage furnace is approved for installation in a mobile

home when a factory-supplied accessory mobile home conversion kit is used. The conversion kit is required for use with both natural and propane gas. The furnace must also be

installed on a factory-supplied accessory combustible floor base or evaporator coil casing.

This furnace is designed for minimum continuous return-air temperature of 60°F (15°C) db or intermittent operation down to

55°F (15°C) db such as when used with a night setback thermostat. Return-air temperature must not exceed 80°F (27°C) db. Failure to follow these return-air temperature limits

may affect reliability of heat exchangers, motors, and controls (See Figure 1)

The furnace should be sized to provide 100 percent of the design heating load requirement plus any margin that occurs

because of furnace model size capacity increments. Heating load estimates can be made using approved methods available

from Air Conditioning Contractors of America (Manual J); American Society of Heating, Refrigerating, and Air-Conditioning Engineers; or other approved engineering

methods. Excessive oversizing of the furnace could cause the furnace and/or vent to fail prematurely.

For accessory installation details, refer to the applicable instruction literature.

NOTE: Remove all shipping materials, parts assemblies and literature before operating the furnace.

Electrostatic Discharge (ESD) Precautions Procedure

FURNACE RELIABILITY HAZARD

Failure to follow this caution may result in unit com- 3onent damage.

Electrostatic discharge can affect electronic compon- ents. Take precautions during furnace installation and servicing to protect the furnace electronic control. Pre- cautions will prevent electrostatic discharges from per-

sonnel and hand tools which are held during the pro- cedure. These precautions will help to avoid exposing the control to electrostatic discharge by putting the furnace, the control, and the person at the same elec- trostatic potential.

1. Disconnect all power to the furnace. Multiple disconnects may be required. DO NOT TOUCH THE

CONTROL OR ANY WIRE CONNECTED TO THE CONTROL PRIOR TO DISCHARGING YOUR BODY'S ELECTROSTATIC CHARGE TO GROUND.

2. Firmly touch the clean, unpainted, metal surface of the furnace chassis which is close to the control. Tools held

in a person's hand during grounding will be satisfactorily discharged.

3. After touching the chassis, you may proceed to service the control or connecting wires as long as you do nothing to recharge your body with static electricity (for example; DO NOT move or shuffle your feet, do not touch ungrounded objects, etc.).

4. If you touch ungrounded objects (and recharge your body with static electricity), firmly touch a clean, unpainted metal surface of the furnace again before touching control or wires.

5. Use this procedure for installed and uninstatled (ungrounded) furnaces.

6. Before removing a new control from its container, discharge your body's electrostatic charge to ground to protect the control from damage. If the control is to be installed in a furnace, follow items 1 through 4 before bringing the control or yourself in contact with the

furnace. Put all used and new controls into containers before touching ungrounded objects.

7. An ESD service kit (available from commercial sources) may also be used to prevent ESD damage.

PERSONAL INJURY AND/OR PROPERTY DAMAGE HAZARD

Improper use or installation of this furnace may result in 3remature furnace component failure. This gas furnace

may be used for heating buildings under construction

3rovided that:

-The furnace is permanently installed with all electrical wiring, piping, venting and ducting installed according to

these installation instructions. A return air duct is

3rovided, sealed to the furnace casing, and terminated outside the space containing the furnace. This prevents a negative pressure condition as created by the

circulating air blower, causing a flame rollout and/or drawing combustion products into the structure.

-The furnace is controlled by a thermostat. It may not be "hot wired" to provide heat continuously to the structure without thermostatic control.

-Clean outside air is provided for combustion. This is to minimize the corrosive effects of adhesives, sealers and

other construction materials. It also prevents the entrainment of drywall dust into combustion air, which can cause fouling and plugging of furnace components.

-The temperature of the return air to the furnace is maintained between 55°F (13°C) and 80°F (27°C), with no evening setback or shutdown. The use of the furnace

while the structure is under construction is deemed to be intermittent operation per our installation instructions.

-The air temperature rise is within the rated rise range on the furnace rating plate, and the gas input rate has been

set to the nameplate value.

-The filters used to clean the circulating air during the construction process must be either changed or

thoroughly cleaned prior to occupancy.

-The furnace, ductwork and filters are cleaned as necessary to remove drywall dust and construction

debris from all HVAC system components after construction is completed.

-Verify proper furnace operating conditions including ignition, gas input rate, air temperature rise, and venting according to these installation instructions.

General

These furnaces are shipped with the following materials to assist in proper furnace installation. These materials are

shipped in the main blower compartment. See Table 2 for loose parts bog contents.

This furnace must:

• be installed so the electrical components are protected from water.

• notbe installeddirectlyon any combustiblematerial other than wood flooring (refer to SAFETY CONSIDERATIONS).

be located close to the chimney or vent and attached to an air distribution system. Refer to Air Ducts section.

be provided ample space for servicing and cleaning.

Always comply with minimum fire protection clearances

shown in Table 1 or on the furnace clearance to combustible construction label.

CARBON MONOXIDE POISONING / COMPONENT DAMAGE HAZARD

Failure to follow this warning could result in personal in-

jury or death and unit component damage.

Corrosive or contaminated air may cause failure of parts containing flue gas, which could leak into the living

space. Air for combustion must not be contaminated by halogen compounds, which include fluoride, chloride,

bromide, and iodide. These elements can corrode heat exchangers and shorten furnace life. Air contaminants

are found in aerosol sprays, detergents, bleaches, clean- ing solvents, salts, air fresheners, and other household products. Do not install furnace in a corrosive or contam- inated atmosphere. Make sure all combustion and circu-

lating air requirements are met, in addition to all local codes and ordinances.

The following types of furnace installations may require OUTDOOR AIR for combustion due to chemical exposures:

• Commercial buildings

• Buildings with indoor pools

• Laundry rooms

• Hobby or craft rooms, and

• Chemical storage areas

If air is exposed to the following substances, it should not be used for combustion air, and outdoor air may be required for combustion:

• Permanent wave solutions

• Chlorinated waxes and cleaners

• Chlorine based swimming pool chemicals

• Water softening chemicals

• De-icing salts or chemicals

• Carbon tetrachloride

• Halogen type refrigerants

• Cleaning solvents (such as perchloroethylene)

• Printing inks, paint removers, varnishes, etc.

• Hydrochloric acid

• Cements and glues

• Antistatic fabric softeners for clothes dryers

• Masonry acid washing materials

All fuel-burning equipment must be supplied with air for fuel combustion. Sufficient air must be provided to avoid negative pressure in the equipment room or space. A positive seal must

be made between the furnace cabinet and the return-air duct to prevent pulling air from the burner area.

Location Relative to Cooling Equipment

The cooling coil must be installed parallel with, or on the downstream side of the unit to avoid condensation in the heat

exchangers. When installed parallel with the furnace, dampers or other flow control must prevent chilled air from entering the

furnace. If the dampers are manually operated, they must be equipped with means to prevent operation of either unit unless the damper is in the full-heat or full-cool position.

Air for Combustion and

Ventilation

Introduction

FURNACE CORROSION HAZARD

Failure to follow this caution may result in furnace damage.

Air for combustion must not be contaminated by halogen

compounds, which include fluoride, chloride, bromide, and iodide. These elements can corrode heat

exchangers and shorten furnace life. Air contaminants are found in aerosol sprays, detergents, bleaches, cleaning solvents, salts, air fresheners, and other household products.

Direct Vent (2-pipe) Applications

When the furnace is installed as a direct vent (2-pipe) furnace,

no special provisions for air for combustion are required.

However, other gas appliances installed in the space with the furnace may require outside air for combustion. Follow the guidelines below to insure that other gas appliances have sufficient air for combustion.

Non-Direct Vent (1-pipe) Applications

When the furnace is installed as a non-direct vent (1-pipe) furnace, it wilt be necessary to insure there is adequate air for

combustion. Other gas appliances installed with the furnace may also require air for combustion and ventilation in addition to the amount of combustion air and ventilation air required for

the furnace. Follow the guidelines below to insure that the furnace and other gas appliances have sufficient air for

combustion.

Ventilated Combustion Air Applications

When the furnace is installed using the ventilated combustion air option, the attic or crawlspace must freely communicate with

the outdoor to provide sufficient air for combustion. The combustion air pipe cannot be terminated in attics or

crawlspaces that use ventilation fans designed to operate during the heating season. If ventilation fans are present in

these areas, the combustion air pipe must terminate outdoors as a Direct Vent/2-Pipe system.

All air for combustion is piped directly to the furnace from a space that is well ventilated with outdoor air (such as an attic or

crawlspace) and the space is well isolated from the living space or garage. In addition, other gas appliances installed in the

space with the furnace may require outside air for combustion.

Follow the guidelines below to insure that the roof or crawlspace walls have sufficient free area to provide sufficient

air for combustion and ventilation for the furnaces. The guidelines below can be used to insure that other gas

appliances have sufficient air for combustion.

Provisions for adequate combustion, ventilation, and dilution air must be provided in accordance with:

• U.S. Installations: Section 9.3 of the NFPA 54/ANSI Z223.1-2009 , Air for Combustion and Ventilation and

applicable provisions of the local building codes.

• Canadian Installations: Part 8 of CAN/CSA-B149.1-2010, Venting Systems and Air

Supply for Appliances and all authorities having jurisdiction.

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in personal injury or death.

The operation of exhaust fans, kitchen ventilation fans,

clothes dryers, attic exhaust fans or fireplaces could create a NEGATIVE PRESSURE CONDITION at the

furnace. Make-up air MUST be provided for the ventilation devices, in addition to that required by the furnace. Refer to the Carbon Monoxide Poisoning

Hazard warning in the venting section of these instructions to determine if an adequate amount of make-up air is available.

The requirements for combustion and ventilation air depend upon whether or not the furnace is located in a space having a

volume of at least 50 cubic feet per 1,000 Btuh (4.8 cubic meters per kW) input rating for all gas appliances installed in

the space.

• Spaces having less than 50 cubic feet per 1,000 Btuh (4.8 cubic meters per kW) require the OUTDOOR

COMBUSTION AIR METHOD.

• Spaces having at least 50 cubic feet per 1,000 Btuh (4.8 cubic meters per kW) may use the INDOOR COMBUSTION AIR, STANDARD or KNOWN AIR

INFILTRATION METHOD.

Outdoor Combustion Air Method

1. Provide the space with sufficient air for proper combustion, ventilation, and dilution of flue gases using permanent horizontal or vertical duct(s) or opening(s) directly communicating with the outdoors or spaces that freely communicate with the outdoors.

2. Figure 6 illustrates how to provide TWO OUTDOOR OPENINGS, one inlet and one outlet combustion and ventilation air openings to the outdoors.

a. One opening MUST commence within 12-in.

(300 mm) of the ceiling and the second opening MUST commence within 12-in. (300 mm) of the floor.

b. Size openings and ducts per Figure 6 and Table 3. c. TWO HORIZONTAL DUCTS require 1 square inch

(25.4 square mm) of free area per 2,000 Btuh (1,100 mm2/kW) of combined input for all gas appliances in

the space per Figure 6 and Table 3.

d. TWO OPENINGS OR VERTICAL DUCTS require 1

square inch (25.4 square mm)of free area per 4,000 Btuh (550 mm2/kW) for combined input of all gas

appliances in the space per Figure 6 and Table 3.

3. ONE OUTDOOR OPENING requires:

a. 1 sq. in. (25.4 square mm)of free area per 3,000 Btuh

(734 mm2/kW) for combined input of all gas appliances in the space per Table 3 and

b. Not less than the sum of the areas of all vent

connectors in the space.

The opening shall commence within 12-in. (300 mm) of the ceiling. Appliances in the space shall have clearances of at

least 1-in. (25 mm) from the sides and back and 6-in. (150 mm) from the front. The opening shall directly communicate with the

outdoors or shall communicate through a vertical or horizontal duct to the outdoors or spaces (crawl or attic) that freely

communicate with the outdoors.

Indoor Combustion Air ° NFPA & AGA Standard and Known-Air-Infiltration Rate

Methods

Indoor combustion air is permitted for combustion, ventilation,

and dilution, if the Standard or Known-Air-Infiltration Rate Method is used.

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in personal injury or death.

Many homes require air to be supplied from outdoors

for furnace combustion, ventilation, and dilution of flue

gases.

The furnace combustion air supply must be provided in

accordance with this instruction manual.
