ELECTROSTATIC DISCHARGE (ESD)

PRECAUTIONS PROCEDURE

FURNACE RELIABILITY HAZARD

Failure to follow this caution may result in unit component damage.

Electrostatic discharge can affect electronic components. Take precautions during furnace installation and servicing to protect the furnace electronic control. Precautions will prevent electrostatic discharges from personnel and hand tools which are held during the procedure. These precautions will help to avoid exposing the control to electrostatic discharge by putting the furnace, the control, and the person at the same electrostatic 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 fur- nace chassis which is close to the control. Tools held in a

person's hand during grounding will be satisfactorily dis- charged.

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 uninstalled (ungroun- ded) furnaces.

6. Before removing a new control from its container, discharge your body's electrostatic charge to ground to protect the

PERSONAL INJURY AND/OR PROPERTY DAMAGE HAZARD

Improper use or installation of this furnace may result in premature furnace component failure. This gas furnace may be used for heating buildings under construction provided

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 provided, 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 1 for loose parts bag contents. This furnace must:

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

• not be installed directly on any combustible material 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

2 or on the furnace clearance to combustible construction label.

CARBON MONOXIDE POISONING / COMPONENT DAMAGE HAZARD

Failure to follow this warning could result in personal injury 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, cleaning solvents, salts, air

fresheners, and other household products. Do not install ftlrnace in a corrosive or contaminated atmosphere. Make sure all combustion and circulating 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

• 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.

FIRE, INJURY OR DEATH HAZARD Failure to follow this warning could result in personal

iniury, death and/or property damage. When the furnace is installed in a residential garage, the

burners and ignition sources must be located at least 18 in. (457 mm) above the floor. The furnace must be located or

protected to avoid damage by vehicles. When the furnace is installed in a public garage, airplane hangar, or other building having a hazardous atmosphere, the furnace must

be installed in accordance with the NFPA 54/ANSI Z223.1-2009 or CAN/CSA B149.2-2010. (See Fig. 5.)

Location Relative to Cooling Equipment

FIRE HAZARD Failure to follow this warning could result in personal

iniury, death and/or property damage. Do not install the furnace on its back or hang furnace with

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 airfor combustion. Follow the guidelines below to insure thatother gas appliances have sufficient air for combustion.

Non-Direct Vent (1-pipe) Applications

When the furnace is installed as a non-direct vent (l-pipe) furnace, it will 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 nmst 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

nmst 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 crawl space) 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.A. 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.

• Canada: Part 8 of the CAN/CSA-B149.1-2010, Venting Systems and Air Supply for Appliances.

FURNACE CORROSION HAZARD

Failure to follow this caution may result in furnace damage. Air for combustion nmst 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.

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in personal iniury 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 availaMe.

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 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 hori-

zontal or vertical duct(s) or opening(s) directly communicat- ing with the outdoors or spaces that freely communicate

with the outdoors.

2. Fig. 6 illustrates how to provide TWO OUTDOOR OPENINGS, one inlet and one outlet combustion and vent-

ilation air opening, to the outdoors.

a. One opening MUST commence within 12 in. (300 ram)

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

b. Size openings and ducts per Fig. 6 and TaMe 3.

c. TWO HORIZONTAL DUCTS require I sq. in. (645 sq.

ram) of free area per 2,000 Btuh (1,100 mm2/kW) of com- bined input for all gas appliances in the space per Fig. 6and

Table 3.

d. TWO OPENINGS OR VERTICAL DUCTS require 1

sq. in. (645 sq. ram) of free area per 4,000 Btuh (550 mm2/kW) for combined input of all gas appliances in the space per Fig. 6 and Table 3.

3. ONE OUTDOOR OPENING requires:

a. 1 sq. in. (645 sq. ram) of free area per 3,000 Btuh (734

mm2/kW) for combined input of all gas appliances in the space per Fig. 6 and Table 3.

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

the space.

The opening shall commence within 12 in. (300 ram) of the ceiling. Appliances in the space shall have clearances of at least 1

in. (25 ram) from the sides and back and 6 in. (150 ram) from the front. The opening shall directly communicate with the outdoors or

shall conmmnicate 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 air is pernfitted for combustion, ventilation, and dilution, if the Standard or Known-Air-Infiltration Method is used.

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in personal iniury 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.

Standard Method

1. The space has no less volume than 50 cubic feet per 1,000 Btuh of the maximum input ratings for all gas appliances

installed in the space and

2. The air infiltration rate is not known to be less than 0.40 air changes per hour (ACH).

The Known Air Infiltration Rate Method shall be used, if the infiltration rate is known to be:

1. Less than 0.40 ACH and

2. Equal to or greater than 0.10 ACH

Infiltration rates greater than 0.60 ACH shall not be used. The minimum required volume of the space varies with the number of

ACH and shall be deternfined per Table 4 or Equations 1 and 2. Deternfine the minimum required volume for each appliance in the

space and add the volumes together to get the total minimum required volume I\_r the space.

Table 4 - Minimum Space Volumes were deternfined by using the following equations from the current edition of the National Fuel

Gas Code ANSI Z223.1/NFPA 54, 9.3.2.2:

1. For other than fan-assisted appliances, such as a draft hood-equipped water heater:

2. For fan-assisted appliances such as this furnace:

of the floor. The minimum dimension of air openings shall be at least 3 in. (80 ram). (See Fig. 7.)

c. Combining space on different floor levels. The volumes of

spaces on different floor levels shall be considered as com- municating spaces if connected by one or more permanent

openings in doors or floors having free area of at least 2 in.2/1,000 Btuh (4,400 mm2/kW) of total input rating of

all gas appliances.

2. An attic or crawlspace may be considered a space that freely communicates with the outdoors provided there are ad-

equate permanent ventilation openings directly to outdoors having free area of at least 1-in.2/4,000 Btuh of total input

rating for all gas appliances in the space.

3. In spaces that use the Indoor Combustion Air Method, in- filtration should be adequate to provide air for combustion,

permanent ventilation and dilution of flue gases. However, in buildings with unusually tight construction, additional air

MUST be provided using the methods described in the Outdoor Combustion Air Method section.

4. Unusually tight construction is defined as Construction

with:

a. Walls and ceilings exposed to the outdoors have a continu-

ous, sealed vapor barrier. Openings are gasketed or sealed

and

b. Doors and openable windows are weatherstripped and

c. Other openings are caulked or sealed. These include joints

around window and door frames, between sole plates and

floors, between wall-ceiling joints, between wall panels,

at penetrations for plumbing, electrical and gas lines, etc.

Combination of Indoor and Outdoor Air

1. Indoor openings shall comply with the Indoor Combus-

tion Air Method below and,

2. Outdoor openings shall be located as required in the Out- door Combustion Air Method mentioned previously and,

3. Outdoor openings shall be sized as follows:

a. Calculate the Ratio of all Indoor Space volume divided by

required volume for Indoor Combustion Air Method be- low.

b. Outdoor opening size reduction Factor is I nfinus the Ra-

tio in a. above.

c. Minimum size of Outdoor openings shall be the size re-

quired in Outdoor Combustion Air Method above multi- plied by reduction Factor in b. above. The minimum di- mension of air openings shall be not less than 3 in. (80 ram).

The following requirements apply to the Standard Method and to the Known Air Infiltration Rate Method.

1. Adjoining rooms can be considered part of a space if: a. There are no closeable doors between rooms.

b. Combining spaces on same floor level. Each opening shall

have free area of at least I in.2/1,000 Btuh (2,000 mm2/kW) of the total input rating of all gas appliances in the space,

but not less than 100 in. 2 (0.06 m2). One opening shall commence within 12 in. (300 ram) of the ceiling and the

CONDENSATE DRAIN CONNECTION

Upflow/Downflow Orientation In the Upflow or Downflow orientation, the condensate trap is

inside the furnace casing. The condensate drain must be routed from the trap through the furnace casing. The condensate drain can

be routed through the left or right side of the casing. (The left or right side is as you are viewing the furnace.) The furnace

condensate drain can be connected to the Air Conditioning condensate drain as shown in Fig. 13.

NOTE: On narrower casings, it may be easier to remove the condensate trap, connect the drain line components and re-install the condensate trap. Read the steps thoroughly to familiarize yourself with the required steps.

For Right Side Condensate Drain:

1. Remove the 7/8-in. knock-out from the right side of the casing. (See Fig. 12 .)

2. Remove the pre-formed drain tube and two spring clamps from the loose parts bag.

3. Slide a spring clamp 1 in. (25 mm) down the plain end of the drain tube.

4. From inside the casing, insert the formed grommet end of the tube through the 7/8-in. knockout in the casing.

5. Pull the tube through the casing from the outside until it is seated in the knockout

6. Attach the plain end of the drain tube to the outlet stub on the drain trap. Secure the drain tube to the trap with the

spring clamp.

7. Slide a spring clamp over the open end of the drain tube outside the casing.

8. Open the spring clamp and connect a field-supplied 1/2-in. CPVC street elbow to the open end of the drain tube. (See

Fig. 14.)

9. Connect additional 1/2-in. CPVC piping to a condensate pump approved for use with acidic furnace condensate or to

a code-approved drain.

For Left Side Condensate Drain Connection:

1. For left side condensate drainage, the drain line is routed from the condensate trap, behind the inducer and out

through the left side of the casing. A pre-formed "Z" pipe is provided in the loose parts bag shipped with the furnace.

The "Z" pipe is long enough to extend out of the casing on the 14 3/16-in. (360 mm) wide furnace. Larger casings will

require a field supplied CPVC pipe and to extend the drain line out of the furnace.

2. The "Z" pipe is connected to the condensate trap by modifying the formed rubber drain tube. Connect the drain line as shown below:

3. Remove the knock-out from the left side of the casing. (See Fig. 12.)

4. Install the grommet for the l/2-in. CPVC drain line in the 7/8-in. knockout in the casing.

5. Remove the pre-formed drain tube, the offset l/2-in. CPVC pipe and two spring clamps from the loose parts bag.

6. Remove the formed grommet on the tube by cutting the tube along the vertical line located about 1 in. (25 mm)

away from the formed grommet.(See Fig. 15.)

7. Slide a spring clamp 1 in. (25 mm) down the plain end of the drain tube.

8. With the bend in the tube oriented horizontally and plain end of the tube pointing away from you, insert the l/2-in.

CPVC pipe into the other end of the drain tube. Rotate the tube so the offset in the tube points away from you. Slide a

spring clamp over the open end of the l/2-in. CPVC tube

and secure the cut end of drain tube to the pipe. (See Fig.

16)

9. Prime the bare end of the pipe with CPVC primer.

10. Route the offset pipe behind the inducer assembly and

through the grommet in the casing, if the "Z" pipe is long enough. If the "Z" pipe is not long enough, continue with

installation.

11. Attach the plain end of the drain tube to the outlet stub on the drain trap. Secure the drain tube to the trap with the

spring clamp.

12. If the "Z" pipe does not extend through the casing, slide a

piece of field supplied CPVC through the grommet in the casing, otherwise, go to Step 17.

13. Cement a 1/2-in. CPVC coupling to the end of the CPVC pipe.

14. Apply cement to the end of the "Z" pipe connected to the condensate trap.

15. Connect the field-supplied CPVC pipe to the CPVC pipe connected to the condensate trap.

16. Cut off excess CPVC pipe outside the casing.

17. Connect additional 1/2-in. CPVC piping to a condensate pump approved for use with acidic furnace condensate or to

a code-approved drain.

18. When a condensate pump is not used, slope the pipe away from the furnace to allow for proper drainage.

Horizontal Orientation

1. In the Horizontal orientation, a field supplied accessory drain trap grommet is required to seal the gap between the

casing and the condensate trap. The condensate trap outlet extends 2 in. (51 mm) below the furnace casing. To allow

for servicing the trap, the condensate drain tube in the loose parts bag can be modified to make a coupler to allow for

future service of the condensate trap and drain line.

2. Remove the knock-out for the condensate trap in the side of the casing.

3. Install the drain trap grommet in the casing. If necessary, remove the trap, install the grommet and re-install the trap.

4. Remove the pre-formed drain tube, the offset l/2-in. CPVC pipe and two spring clamps from the loose parts bag.

5. Remove the formed grommet on the tube to create an elbow or straight connector. (See Fig. 15.)

6. Connect the cut tube to the outlet of the condensate trap with 1 spring clamp.

7. Slide the other spring clamp down the plain end of the drain tube.

8. Connect additional l/2-in. CPVC piping to the open end of the tube.

9. Slide the spring clamp down over the l/2-in. CPVC pipe

10. Connect additional l/2-in. CPVC piping to a condensate pump approved for use with acidic furnace condensate or to a code-approved drain.

11. When a condensate pump is not used, slope the pipe away from the furnace to allow for proper drainage.
