HORIZONTAL INSTALLATION

The coil and furnace must be fully supported when used in the horizontal position.

Three brackets (with screws) are included with downflow furnaces for installation to stabilize and secure the furnace and TXC cased coil in the horizontal

position. See Figure 4.

IMPORTANT:

The 2/4TXC cased coil must be placed downstream of the furnace. In horizontal installations, the apex of the coil may point either toward or away from the furnace. See the 2/4TXC coil Installer's Guide for more details.

The cased coil is secured to the furnace and both the furnace and the cased coil must be properly supported.

The brackets mount using the rear screws on the coil case and use the screws provided to secure the bracket to the furnace. The remaining bracket is placed as close to center as possible (horizontally) between the coil case front and the furnace bottom channel (for downflow/horizontal furnace). Use four of the screws provided to secure the bracket. The upflow furnace,

converted to horizontal, aligns and attaches the TXC coil as in Figure 1. However, the coil requires additional support. This furnace may be installed in an attic or crawl space in the horizontal position by placing the furnace on the left or right side (as viewed from the front in the upright position). The horizontal furnace installation in an attic should be on a service platform large enough to allow for proper clearances on all sides and service access to the front of the furnace (See Clearance

Table on Outline Drawings and Figure 5).

7

8

Installer’s Guide

If the furnace is suspended using perforated steel strap

(plumber’s strap), it must be supported at all four corners and in the middle at the front of the furnace. The forward most screw on the side of the furnace may be used to connect the strapping (See Figure 6). Line contact is only permissible between lines formed by the intersection of the top and two sides of the furnace casing and the building joists, studs, or framing.

5

TYPICAL UPFLOW/HORIZONTAL ATTIC INSTALLATION

A cutout is provided on both sides of the downflow furnace cabinet to allow a 90° elbow to be attached inside the cabinet and the vent piping to connect there. In horizontal, the downflow furnace may be vented through the top of the cabinet if needed. In vertical configuration, the downflow furnace may be vented using the side cabinet cutouts. This venting configuration could be used if an electronic air cleaner is installed.

When the downflow furnace is vented through the left side of the furnace cabinet in horizontal or vertical configuration, Type B vent pipe must be used within the cabinet.

6

AIR FOR COMBUSTION AND VENTILATION

Adequate flow of combustion and ventilating air must not be obstructed from reaching the furnace. Air openings provided in the furnace casing must be kept free of obstructions which restrict the flow of air. Airflow restrictions affect the efficiency and safe operation of the furnace. Keep this in mind should you choose to remodel or change the area which contains your furnace.

Furnaces must have a free flow of air for proper performance.

Provisions for combustion and ventilation air shall be made in accordance with “latest edition” of Section 5.3,

Air for Combustion and Ventilation, of the National

Fuel Gas Code, ANSI Z223.1, or Sections 7.2, 7.3 or 7.4

of CAN/ CGA B149 Installation Codes, and applicable provisions of the local building codes. Special conditions created by mechanical exhausting of air and fireplaces must be considered to avoid unsatisfactory furnace operation.

Furnace locations may be in “confined space” or “unconfined space”. Unconfined space is defined in Table 2 and

Figure 7. These spaces may have adequate air by infiltration to provide air for combustion, ventilation, and dilution of flue gases. Buildings with tight construction

(for example, weather stripping, heavily insulated, caulked, vapor barrier, etc.), may need additional air provided as described for confined space.

Confined spaces are installations with less than 50 cu.

ft. of space per 1000 BTU/hr input from all equipment installed. Air for combustion and ventilation requirements can be supplied from inside the building as in

Figure 9 or from the outdoors, as in Figure 10.

Installer’s Guide

DUCT CONNECTIONS

Air duct systems should be installed in accordance with standards for air conditioning systems, National Fire

Protection Association Pamphlet No. 90. They should be sized in accordance with ACCA Manual D or whichever is applicable.

Central furnaces, when used in connection with cooling units, shall be installed in parallel or on the upstream side of the cooling units to avoid condensation in the heating element, unless the furnace has been specifically approved for downstream installation. With a parallel flow arrangement, the dampers or other means used to control flow of air shall be adequate to prevent chilled air from entering the furnace, and if manually operated, must be equipped with means to prevent operation of either unit unless the damper is in full heat or cool position.

On any job, flexible connections of nonflammable material may be used for return air and discharge connections to prevent transmission of vibration. Though these units have been specifically designed for quiet, vibration free operation, air ducts can act as sounding boards and could, if poorly installed, amplify the slightest vibration to the annoyance level.

When the furnace is located in a utility room adjacent to the living area, the system should be carefully designed with returns which minimize noise transmission through the return air grille. Although these winter air conditioners are designed with large blowers operating at moderate speeds, any blower moving a high volume of air will produce audible noise which could be objectionable when the unit is located very close to a living area. It is often advisable to route the return air ducts under the floor or through the attic. Such design permits the installation of air return remote from the living area (i.e. central hall).

When the furnace is installed so that the supply ducts carry air circulated by the furnace to areas outside the space containing the furnace, the return air shall also be handled by a duct(s) sealed to the furnace and terminating outside the space containing the furnace.

Minimum return air/“air entering” temperature for the furnace is 55° F.

Where there is no complete return duct system, the return connection must be run full size from the furnace to a location outside the utility room, basement, attic, or crawl space.

Do Not install return air through the back of the

furnace cabinet.

RETURN AIR DUCT CONNECTION

All return air duct systems should provide for installation of return air filters.

NOTE:

On upflow 5 ton airflow models, if the airflow requirement exceeds 1800 CFM, these models will require return air openings and filters on both sides; OR 1 side and the bottom; OR just the bottom.

1. Set the furnace in place.

2. For side return installations on upflow models, remove the insulation around the opening in the blower compartment.

3. The side panels on upflow furnaces include locating notches which may be used as guides for cutting an opening for return air. Refer to Figure 11 and the outline drawing on page 4 for duct connection dimensions for various furnaces.

4. If a 3/4" flange is to be used for attaching the air inlet duct, add to cut where indicated by solid lines in

Figure 11. Cut corners diagonally and bend outward to form flange.

5. If flanges are not required, and a filter frame is installed, cut along knockout guidelines.

6. Upflow Furnaces: filter retainer brackets are factory supplied for bottom return. Use the filter retainer brackets on either side or on bottom if filter is to be used within the furnace cabinet.

If bottom return opening is not used, fabricate and install a sheet metal plate in the bottom of the furnace cabinet q

8. When replacing a furnace, old duct work should be cleaned out. Thin cloths should be placed over the registers and the furnace fan should be run for

10 minutes. Don’t forget to remove the cloths before you start the furnace.

RETURN AIR FILTER

Filters are field supplied for these furnaces. These furnaces require high velocity type air filters which may be located within the furnace blower compartment for UP-

FLOW furnaces in either a BOTTOM or SIDE (left side or right side) return air inlet. See Figures 13 and 14.

Some filters may need to be trimmed for side or bottom filter use.

NOTE:

On upflow 5 ton airflow models, if the airflow requirement exceeds 1800 CFM, these models will require return air openings and filters on both sides; OR 1 side and the bottom; OR just the bottom.

Downflow furnace filters must be located outside the furnace cabinet. Typical installations are shown on page

10 in Figure 15. Tables 5 and 6 on page 11, provide information for installation of the filter retaining brackets shipped with downflow furnaces.

GENERAL VENTING INSTRUCTIONS

VENT PIPING

These furnaces have been classified as Fan-Assisted

Combustion System, Category I furnaces under the “latest edition” provisions of ANSI Z21.47 and CAN/CGA 2.3

standards. Category I furnaces operate with a non-positive vent static pressure and with a flue loss of not less than 17 percent.

NOTE:

If desired, a side wall termination can be accomplished through the use of an “add-on” draft inducer. The inducer must be installed according to the inducer manufacturer’s instructions. Set the barometric pressure relief to achieve -0.02 inch water column.

NOTE:

When the downflow furnace is vented through the left side of the furnace cabinet using the provided cutout,

Type B vent piping must be used.

The furnace shall be connected to a factory built chimney or vent complying with a recognized standard, or a masonry or concrete chimney lined with a lining material acceptable to the authority having jurisdiction.

▲

WARNING

Furnace venting into an unlined masonry chimney or concrete chimney is prohibited.

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

WARNING

CARBON MONOXIDE POISONING HAZARD

Failure to follow the steps outlined below for each appliance connected to the venting system being placed into operation could result in carbon monoxide poisoning or death.

The following steps shall be followed for each appliance connected to the venting system being placed into operation, while all other appliances connected to the venting system are not in operation:

1. Seal any unused openings in the venting system.

2. Inspect the venting system for proper size and horizontal pitch, as required in the National Fuel

Gas Code, ANSI Z223.1/NFPA 54 or the CAN/CGA

B149 Installation Codes and these instructions.

Determine that there is no blockage or restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition.

3. As far as practical, close all building doors and windows and all doors between the space in which the appliance(s) connected to the venting system are located and other spaces of the building.

4. Close fireplace dampers.

5. Turn on clothes dryers and any appliance not connected to the venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they are operating at maximum speed.

Do not operate a summer exhaust fan.

6. Follow the lighting instructions. Place the appliance being inspected into operation. Adjust the thermostat so appliance is operating continuously.

7. If improper venting is observed during any of the above tests, the venting system must be corrected in accordance with the National Fuel Gas Code,

ANSI Z221.1/NFPA 54 and/or CAN/CGA B149

Installation Codes.

8. After it has been determined that each appliance connected to the venting system properly vents where tested as outlined above, return doors, windows, exhaust fans, fireplace dampers and any other gas-fired burning appliance to their previous conditions of use.

VENTING INTO A MASONRY CHIMNEY

If the chimney is oversized, the liner is inadequate, or flue-gas condensation is a problem in your area, consider using the chimney as a pathway or chase for type “B” vent or flexible vent liner. If flexible liner material is used, size the vent using the “B” vent tables, then reduce the maximum capacity by 20% (multiply 0.80 times the maximum capacity).

Internal Masonry Chimneys

Venting of fan assisted appliances into a lined, internal masonry chimney is allowed only if it is common vented with at least one natural draft appliance; OR, if the chimney is lined with type “B”, double wall vent or suitable flexible liner material (See Table 7).

▲

WARNING

The chimney liner must be thoroughly inspected to insure no cracks or other potential areas for flue gas leaks are present in the liner. Liner leaks will result in early deterioration of the chimney.

Failure to follow this warning could result in carbon monoxide poisoning or death.

18-CD19D4-26 13

FIELD WIRING DIAGRAMS

Installer’s Guide

Venting of fan assisted appliances into external chimneys (one or more walls exposed to outdoor temperatures), requires the chimney be lined with type “B”, double wall vent or suitable flexible chimney liner material. This applies in all combinations of common venting as well as for fan assisted appliances vented alone.

The following installation practices are recommended to minimize corrosion caused by condensation of flue products in the furnace and flue gas system.

▲

WARNING

CARBON MONOXIDE POISONING HAZARD

Failure to follow the installation instructions for the venting system being placed into operation could result in carbon monoxide poisoning or death.

1. Avoid an excessive number of bends.

2. Horizontal runs should pitch upward at least 1/4" per foot.

3. Horizontal runs should be as short as possible.

4. All vent pipe or connectors should be securely supported and must be inserted into, but not beyond the inside wall at the chimney vent.

5. When vent connections must pass through walls or partitions of combustible material, a thimble must be used and installed according to local codes.

6. Vent pipe through the roof should be extended to a height determined by National Fuel Gas Code or local codes. It should be capped properly to prevent rain water from entering the vent. Roof exit should be waterproofed.

7. Use type “B” double wall vent when vent pipe is routed through cool spaces (below 60° F.).

8. Where long periods of airflow are desired for comfort, use long fan cycles instead of continuous airflow.

9. Apply other good venting practices as stated in the venting section of the National Fuel Gas Code

ANSI Z223.1 “latest edition”.

10. Vent connectors serving appliance vented by

natural draft or non-positive pressure shall not be connected into any portion of a mechanized draft system operating under positive pressure.

11. Horizontal pipe runs must be supported by hangers, straps or other suitable material in intervals at a minimum of every 3 feet of pipe.

12. A furnace shall not be connected to a chimney or flue serving a separate appliance designed to burn solid fuel.

SEQUENCE OF OPERATION Thermostat call for heat

R and W thermostat contacts close signaling the control module to run its self-check routine. After the control module has verified that the pressure switch contacts are open and the limit switch(es) contacts are closed, the draft blower will be energized.

As the induced draft blower comes up to speed, the pressure switch contacts will close and the ignitor warm up period will begin. The ignitor will heat for approx. 17 seconds, then the gas valve is energized to permit gas flow to the burners. The flame sensor confirms that ignition has been achieved within the 6 second ignition trial period.

After the flame sensor confirms that ignition has been achieved, the delay fan ON period (fixed at 45 seconds) begins timing. After the delay of 45 seconds, the indoor blower motor will be energized and will continue to run during the heating cycle.

When the thermostat is satisfied, R and W thermostat contacts open, the gas valve will close, the flames will extinguish, and the induced draft blower will be de-energized. The indoor blower motor will continue to run for the fan off period (fixed at 100 seconds), then will be de-energized by the control module.

If the installation is 2,000 ft. or above, the furnace input rate (BTUH) shall be reduced 4% for each 1,000 ft.

above sea level. The furnace input rate shall be checked by clocking the gas flow rate (CFH) and multiplying by the heating value obtained from the local utility supplier for the gas being delivered at the installed altitude.

Input rate changes can be made by adjusting the manifold pressure (min 3.0 - max 3.7 in. W.C. - Natural Gas) or changing orifices (orifice change may not always be required).

Installation of this furnace at altitudes above 2,000 ft.

(610m) shall be in accordance with local codes, or in the absence of local codes, the National Fuel Gas Code,

ANSI Z223.1/ NFPA 54 or National Standard of

Canada, Natural Gas and Propane Installation Code,

CSA B149.1. Installation of this furnace at altitudes above 2,000 ft. (610m) shall be made in accordance with the listed high Altitude Conversion Kit available with this furnace.

If the desired input rate cannot be achieved with a change in manifold pressure, then the orifices must be changed. LP installations will require an orifice change.

IMPORTANT:

Re-install the propane orifices to the same depth as the orifices supplied with the equipment.

See Table 13 for help in selecting orifices if orifice change is required. Furnace input rate and temperature rise should be checked again after changing orifices to confirm the proper rate for the altitude.

Installations above 4,000 feet may require a pressure switch change. If required, use the BAYHALT*** Kit

(High Altitude Accessory Kit) listed in PRODUCT DATA.

WARNING

DO NOT attempt to manually light the burner.

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

Lighting instructions appear on each unit. Each installation must be checked out at the time of initial start up to insure proper operation of all components. Check out should include putting the unit through one complete cycle as outlined below.

Turn on the main electrical supply and set the thermostat above the indicated temperature. The ignitor will automatically heat, then the gas valve is energized to permit the flow of gas to the burners. After ignition and flame is established, the flame control module monitors the flame and supplies power to the gas valve until the thermostat is satisfied.

TO SHUT OFF

For complete shutdown: Move the control switch on the main gas valve to the “OFF” position (See Figures 18 and 19). Disconnect the electrical supply to the unit.

▲

CAUTION

If this is done during the cold weather months, provisions must be taken to prevent freeze-up of all water pipes and water receptacles.

Failure to follow this warning could result in property damage.

Whenever your house is to be vacant, arrange to have someone inspect your house for proper temperature. This is very important in below freezing weather. If for any reason your furnace should fail to operate damage could result, such as frozen water pipes.

CONTROL AND SAFETY SWITCH ADJUSTMENT

LIMIT SWITCH CHECK OUT

The limit switch is a safety device designed to close the gas valve should the furnace become overheated. Since proper operation of this switch is important to the safety of the unit, it must be checked out on initial

start up by the installer.

To check for proper operation of the limit switches, set the thermostat to a temperature higher than the indicated temperature to bring on the gas valve. Restrict the airflow by blocking the return air or by disconnecting the blower. When the furnace reaches the maximum outlet temperature as shown on the rating plate, the burners must shut off. If they do not shut off after a reasonable time and overheating is evident, a faulty limit switch is probable and the limit switch must be replaced. After checking the operation of the limit control, be sure to remove the paper or cardboard from the return air inlet, or reconnect the blower.

AIRFLOW ADJUSTMENT

Check inlet and outlet air temperatures to make sure they are within the ranges specified on the furnace rating nameplate. If the airflow needs to be increased or decreased, see the wiring diagram for information on changing the speed of the blower motor.

▲

WARNING

Disconnect power to the unit before removing the blower door.

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

This unit is equipped with a blower door switch which cuts power to the blower and gas valve causing shutdown when the door is removed. Operation with the door removed or ajar can permit the escape of dangerous fumes. All panels must be securely closed at all times for safe operation of the furnace.

NOTE:

Direct drive motors have bearings which are permanently lubricated and under normal use, lubrication is not recommended.

INDOOR BLOWER TIMING

The control module controls the indoor blower. The blower starts approximately 45 seconds after ignition.

The FAN-OFF period is approximately 100 seconds from the interruption of gas flow.

ROOM AIR THERMOSTAT HEAT ANTICIPATOR

ADJUSTMENT

Set the thermostat heat anticipator according to the current flow measured, or the settings found in the notes on the furnace wiring diagram (found inside the furnace casing).

INSTRUCTIONS TO THE OWNERS

In the event that electrical, fuel, or mechanical failures occur, the owner should immediately turn the gas supply off at the manual gas valve, located in the burner compartment (See Figure

17). Also turn off electrical power to the furnace and contact the service agency designated by your dealer.

▲

WARNING

Should overheating occur, or the gas supply fail to shut off, shut off the gas valve to the unit before shutting off the electrical supply. Failure to follow this warning could result in property damage, personal injury, or death.

OPERATING INFORMATION

FLAME ROLL-OUT DEVICE

All models are equipped with a thermal control device on the burner cover. In case of flame roll-out, the device will cause the circuit to open which shuts off all flow of gas.

ABNORMAL CONDITIONS

1. EXCESSIVE COMBUSTION VENT PRESSURE OR

FLUE BLOCKAGE

If pressure against the induced draft blower outlet becomes excessive, the pressure switch will shut off the gas valve until acceptable combustion pressure is again available.

2. LOSS OF FLAME OR GAS SUPPLY FAILURE

If loss of flame occurs during a heating cycle (when flame is not present at the sensor), the control module will retry the ignition sequence up to two times after the sensor cools. If ignition is not achieved, it will lockout the furnace.

3. POWER FAILURE

If there is a power failure during a heating cycle, the system will restart the ignition sequence automatically when power is restored, if the thermostat still calls for heat.

IFC ERROR FLASH CODES

4. INDUCED DRAFT BLOWER FAILURE

If pressure is not sensed by the pressure switch, it will not allow the gas valve to open, therefore the unit will not start. If failure occurs during a running cycle, the pressure switch will cause the gas valve to close and shut the unit down.

▲

WARNING

Failure to follow safety warnings exactly, could result in a fire or explosion causing property damage, personal injury or loss of life.

— Do not store or use gasoline or other flammable vapors and liquids in the vicinity of this or any other appliance.

— WHAT TO DO IF YOU SMELL GAS

• Do not try to light any appliance.

• Do not touch any electrical switch; do not use any phone in your building.

• Immediately call your gas supplier from a neighbor’s phone. Follow the gas supplier’s instructions.

• If you cannot reach your gas supplier, call the fire department.

1. GENERAL INSPECTION — Examine the furnace installation annually for the following items: a. All flue product carrying areas external to the furnace

(i.e. chimney, vent connector) are clear and free of obstruction. A vent screen in the end of the vent (flue) pipe must be inspected for blockage annually.

b. The vent connector is in place, slopes upward and is physically sound without holes or excessive corrosion.

c. The return air duct connection(s) is physically sound, is sealed to the furnace and terminates outside the space containing the furnace.

d. The physical support of the furnace should be sound without sagging, cracks, gaps, etc., around the base so as to provide a seal between the support and the base.

e. There are no obvious signs of deterioration of the furnace.

2. FILTERS — Filters should be cleaned or replaced (with high velocity filters only), monthly and more frequently during high use times of the year such as midsummer or midwinter.

3. BLOWERS — The blower size and speed determine the air volume delivered by the furnace. The blower motor bearings are factory lubricated and under normal operating conditions do not require servicing. If motor lubrication is required it should only be done by a qualified servicer. Annual cleaning of the blower wheel and housing is recommended for maximum air output, and this must be performed only by a qualified servicer or service agency.

4. IGNITER — This unit has a special hot surface direct ignition device that automatically lights the burners.

Please note that it is very fragile and should be handled with care.

▲

WARNING

Do not touch igniter. It is extremely hot. Failure to follow this warning could result in severe burns.

5. BURNER — Gas burners do not normally require scheduled servicing, however, accumulation of foreign material may cause a yellowing flame or delayed ignition. Either condition indicates that a service call is required. For best operation, burners must be cleaned annually using brushes and vacuum cleaner.

Turn off gas and electric power supply. To clean burners, remove the top burner bracket. Lift burners from orifices.

NOTE:

Be careful not to break igniter when removing burners.

Clean burners with brush and/or vacuum cleaner.

Reassemble parts by reversal of the above procedure.

6. HEAT EXCHANGER/FLUE PIPE — These items must be inspected for signs of corrosion, and/or deterioration at the beginning of each heating season by a qualified service technician and cleaned annually for best operation. To clean flue gas passages, follow recommendations below: a. Turn off gas and electric power supply.

b. Inspect flue pipe exterior for cracks, leaks, holes or leaky joints.

c. Remove burner compartment door from furnace.

d. Inspect around insulation covering flue collector box.

Inspect induced draft blower connections to the flue pipe connection.

e. Remove burners. (See 4.) f. Use a mirror and flashlight to inspect interior of heat exchanger, be careful not to damage the igniter, flame sensor or other components.

g. If any corrosion is present, contact a service agency.

Heat exchanger should be cleaned by a qualified service technician.

h. After inspection is complete replace burners and furnace door.

i. Restore gas supply. Check for leaks using a soap solution. Restore electrical supply. Check unit for normal operation.

7. COOLING COIL CONDENSATE DRAIN — If a cooling coil is installed with the furnace, condensate drains should be checked and cleaned periodically to assure that condensate can drain freely from coil to drain. If condensate cannot drain freely water damage could occur. (See

AIRFLOW ADJUSTMENT

Check inlet and outlet air temperatures to make sure they are within the ranges specified on the furnace rating nameplate. If the airflow needs to be increased or decreased, see the wiring diagram for information on changing the speed of the blower motor.

WARNING

Disconnect power to the unit before removing the blower door. Failure to follow this warning could result in personal injury from moving parts.

This unit is equipped with a blower door switch which cuts power to the blower and gas valve causing shutdown when the door is removed. Operation with the door removed or ajar can permit the escape of dangerous fumes. All panels must be securely closed at all times for safe operation of the furnace.

INDOOR BLOWER TIMING

Heating: The control module controls the indoor blower. The blower start is fixed at 45 seconds after ignition. The FAN-

OFF period is field selectable by dip switches at 60, 100, 140, or 180 seconds. The factory setting is 100 seconds (See wiring diagram).

Cooling: The fan delay off period is factory set at 0 seconds.

The option for 80 second delay off is field selectable (See wiring diagram).
