Installation
General
1 INSTALLATION — Install this unit in accordance with
The American National Standard Z223.1-latest edition manual entitled “National Fuel Gas Code,” and the requirements or codes of the local utility or other authority having jurisdiction.
Additional helpful publications available from the “National Fire Protection Association” are: NFPA-90A ­Installation of Air Conditioning and Ventilating Systems 1985 or latest edition. NFPA-90B - Warm Air Heating and Air Conditioning Systems 1984.
These publications are available from:
National Fire Protection Association, Inc. Batterymarch Park Quincy, MA 02269
2 PRE-INSTALLATION CHECK-POINTS — Before
attempting any installation, carefully consider the following points:
Structural strength of supporting members (Rooftop
Installation) Clearances and provision for servicing Power supply and wiring Gas supply and piping Air duct connections and sizing Drain facilities and connections Location for minimum noise and vibration - away from
bedroom windows
Location Considerations
The metal parts of this unit may be subject to rust or deterioration in adverse environmental conditions. This oxidation could shorten the equipment’s useful life. Salt spray, fog or mist in seacoast areas, sulphur or chlorine from lawn watering systems, and various chemical contaminants from industries such as paper mills and petroleum refineries are especially corrosive.
If the unit is to be installed in an area where contaminants are likely to be a problem, give special attention to the equipment location and exposure.
1 Avoid having lawn sprinkler heads spray directly on the
unit cabinet.
2 In coastal areas locate the unit on the side of the building
away from the waterfront.
3 Shielding by a fence or shrubs may give some protection.
1 Frequent washing of the cabinet, fan blade and coil with
fresh water will remove most of the salt or other contaminants that build up on the unit.
2 Regular cleaning and waxing of the cabinet with an
automobile polish will provide some protection.
3 A liquid cleaner may be used several times a year to
remove matter that will not wash off with water.
Several different types of protective coatings are offered in some areas. These coatings may provide some benefit, but the effectiveness of such coating materials cannot be verified by the equipment manufacturer.
The best protection is frequent cleaning, maintenance and minimal exposure to contaminants.
Outside Installation
(Typical outdoor slab installation is shown in Figure 7.)
1 Select a location where external water drainage cannot
collect around unit.
2 Provide a level slab sufficiently high enough above grade
to prevent surface water from entering the unit
3 Locate the unit to provide proper access for inspection
and servicing as shown in Figure 9.
4 Locate unit where operating sounds will not disturb
owner or neighbors.

5 Locate unit so roof runoff water does not pour directly on
the unit. Provide gutter or other shielding at roof level. Do not locate unit in an area where excessive snow drifting may occur or accumulate.
6 Where snowfall is anticipated, the height of the unit
above the ground level must be considered. Mount unit high enough to be above anticipated maximum area snowfall and to allow combustion air to enter the combustion air inlet.
7 Select an area which will keep the areas of the vent, air
intake, and A/C condenser fins free and clear of obstructions such as weeds, shrubs, vines, snow, etc. Inform the user accordingly.
Attaching Exhaust and Combustion Air Inlet Hoods
IMPORTANT: Do not operate this unit without the
exhaust/combustion air inlet hood properly installed. This hood is shipped in a carton in the blower compartment inside the unit and must be attached when the unit is installed. See Figure 5.
To attach exhaust/combustion air inlet hood:

Rooftop Installation
1 Before locating the unit on the roof, make sure that the
roof structure is adequate to support the weight involved. (See Electrical & Physical Tables in this manual.) THIS
IS VERY IMPORTANT AND THE INSTALLER’S RESPONSIBILITY.
2 For rigging and roofcurb details, see Figures 11, 12, 13
and 14.
3 The location of the unit on the roof should be such as to
provide proper access for inspection and servicing.
IMPORTANT: If unit will not be put into service immediately, block off supply and return air openings to prevent excessive condensation.
Ducting
The installing contractor should fabricate ductwork in accordance with local codes. Use industry manuals as a guide when sizing and designing the duct system. Contact Air Conditioning Contractors of America, 1513 16th St. N.W., Washington, D.C. 20036.
Place the unit as close to the conditioned space as possible allowing clearances as indicated. Run ducts as directly as possible to supply and return outlets. Use of non-flammable weatherproof flexible connectors on both supply and return connections at unit to reduce noise transmission is recommended.
On ductwork exposed to outside temperature and humidity, use a minimum of 2” of insulation and a vapor barrier. Distribution system in attic, furred space or crawl space should be insulated with at least 2” of insulation. Half-inch to 1” thick insulation is usually sufficient for ductwork inside the air conditioned space.
Provide balancing dampers for each branch duct in the supply system. Properly support ductwork from the structure.
IMPORTANT: In the event that the return air ducts must be run through an “unconfined” space containing other fuel burning equipment, it is imperative that the user be informed against future changes in construction which might change this to a “confined space.” Also, caution the user against any future installation of additional equipment (such as power ventilators), within the existing unconfined and/or confined space which might create a negative pressure within the vicinity of other solid, liquid, or gas fueled units.
Return Air
Figure 10A: Flat rooftop installation, attic or drop ceiling distributing system. Mounted on roofcurb. Curb must be level.
I-742-01
Figure 10B: Flat rooftop installation, attic or drop ceiling distributing system. Mounted on roofcurb. Curb must be level.
I-742-02
Do not, under any circumstances, connect return ductwork to any other heat producing device such as fireplace insert, stove, etc. Unauthorized use of such devices may result in fire, carbon monoxide poisoning, explosion, personal injury, property damage or death.
DANGER
!
Never allow products of combustion or the flue products to enter the return air ductwork, or the circulating air supply. All return ductwork must be adequately sealed and secured to the furnace with sheet metal screws, and joints taped. All other duct joints must be secured with approved connections and sealed airtight.
Failure to prevent products of combustion from being circulated into the living space can create potentially hazardous conditions, including carbon monoxide poisoning that could result in personal injury or death.

Gas Supply, Condensate Drain and Piping
Gas Connection
IMPORTANT: Connect this unit only to gas supplied by a
commercial utility.
1 Install gas piping in accordance with local codes and
regulations of the local utility company. In the absence of local codes, the installation must conform to the specifications of the National Fuel Gas Code, ANSI Z223.1 - latest edition.
NOTE: The use of flexible gas connectors is not permitted.
2 Connect the gas line to the gas valve supplied with unit.
Routing can be through the gas pipe opening shown in Figures 7 or 10 or through the base as shown in Figure
18.
3 Size the gas line to the furnace adequate enough to
prevent undue pressure drop and never less than 1/2”.
4 Install a drip leg or sediment trap in the gas supply line as
close to the unit as possible.
5 Install an outside ground joint union to connect the gas
supply to the control assembly at the burner tray.
6 Gas valves have been factory installed. Install a manual
gas valve where local codes specify a shut-off valve outside the unit casing. (See Figure 15.)
7 Make sure piping is tight. A pipe compound resistant to
the action of liquefied petroleum gases must be used at all threaded pipe connections.
8 IMPORTANT: Any additions, changes or conversions
required for the furnace to satisfactorily meet the application should be made by a qualified installer, service agency or the gas supplier, using factory-specified or approved parts. In the commonwealth of Massachusetts, installation must be performed by a licensed plumber or gas fitter for appropriate fuel.
IMPORTANT: Disconnect the furnace and its individual shutoff valve from the gas supply piping during any pressure testing of that system at test pressures in excess of 1/2 pound per square inch gauge or isolate the system from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of this gas supply system at pressures equal to or less than 1/2 PSIG.
IMPORTANT: Check the rating plate to make certain the unit is equipped to burn the type of gas supplied. Care should be taken after installation of this equipment that the gas control valve not be subjected to high gas supply line pressure.
In making gas connections, avoid strains as they may cause noise and damage the controls. A backup wrench is required to be used on the valve to avoid damage.
The capacities of gas pipe of different diameters and lengths in cu. ft. per hr. with pressure drop of 0.3 in. and specific gravity of 0.60 (natural gas) are shown in Table 1.
After determining the pipe length, select the pipe size which will provide the minimum cubic feet per hour required for the gas input rating of the furnace. By formula:
Gas Input of Furnace (BTU/HR)
Cu. Ft. Per Hr. Required =
Heating Value of Gas
(BTU/FT3)
The gas input of the furnace is marked on the furnace rating plate. The heating value of the gas (BTU/FT3) may be determined by consulting the local natural gas utility or the L.P. gas supplier.
LP Conversion
Convert the unit to use liquefied petroleum (LP) gas by replacing with the gas valve supplied in the conversion kit. The LP gas valve maintains the proper manifold pressure for LP gas. The correct burner LP orifices are included in the kit.
IMPORTANT: To remove the natural gas valve, remove the four screws securing the manifold pipe to the burner tray. Remove the manifold pipe with gas valve attached.

ROOF OR GROUND LEVEL INSTALLATION
Never test for gas leaks with an open flame. It can cause an explosion or fire resulting in property damage, personal injury or death. Use a commercially available soap solution made specifically for the detection of leaks to check all connections as specified in the Gas Supply and Piping section of these instructions.
DANGER
!
This unit is equipped at the factory for use on natural gas only. Conversion to LP gas requires a special kit supplied by the distributor or manufacturer. Mailing addresses are listed on the furnace rating plate, parts list and warranty. Failure to use the proper conversion kit can cause fire, carbon monoxide poisoning, explosion, personal injury, property damage or death.

NOTE: Order the correct LP conversion kit from the furnace manufacturer. See Conversion Kit Index shipped with unit for proper LP kit number. Furnace conversion to LP gas must be performed by a qualified technician.
Adjusting or Checking Furnace Input
– Natural Gas Line Pressure 5” - 10.5” W.C. – LP Gas Line Pressure 11” - 13” W.C.
– Natural Gas Manifold Pressure 3.5” W.C – LP Gas Manifold Pressure - 10” W.C.
Supply and manifold pressure taps are located on the gas valve body 1/8” N.P.T. and on the manifold.
Use a properly calibrated manometer gauge for accurate gas pressure readings.
Only small variations in the gas flow should be made by means of the pressure regulator adjustment. Furnaces functioning on LP gas must be set by means of the tank or branch supply regulators. The furnace manifold pressure should be set at 10” W.C. at the gas control valve.
To adjust the pressure regulator, remove the regulator cap and turn the adjustment screw clockwise to increase pressure or counterclockwise to decrease pressure. Then replace the
regulator cap securely.
Any necessary major changes in the gas flow rate should be made by changing the size of the burner orifices. To change orifice spuds, shut off the manual main gas valve and remove the gas manifold.
For elevations up to 2,000 feet, rating plate input ratings apply. For high altitudes (elevations over 2,000 ft.), see conversion kit index 92-21519-XX for derating and orifice spud sizes.
Check of input is important to prevent over-firing of the furnace beyond its design-rated input. NEVER SET INPUT ABOVE THAT SHOWN ON THE RATING PLATE. Use the following table or formula to determine input rate.
Heating Value of Gas (BTU/Cu. Ft.) x 3600
Cu. Ft. Per Hr. Required =
Time in Seconds
(for 1 Cu. Ft.) of Gas
Start the furnace and measure the time required to burn one cubic foot of gas. Prior to checking the furnace input, make certain that all other gas units are shut off, with the exception of pilot burners. Time the meter with only the furnace in operation.
IMPORTANT NOTE FOR ALTITUDES ABOVE 2,000 FEET (610 METERS): The main burner orifices in your furnace and in these
kits are sized for the nameplate input and intended for installations at elevations up to 2,000 feet in the USA or Canada, or for elevations of 2,000 - 4,500 feet (610 -1,373 meters) in Canada if the unit has been derated at the factory. For elevations above 2,000 feet (610 meters) IN THE USA ONLY (see ANSI- Z223.1), the burner orifices must be sized to reduce the input 4% for each 1,000 feet (305 meters) above sea level.
NOTICE: Derating of the heating input for high altitude in the field is unlawful in Canada (refer to CAN/CGA 2.17). Units installed in altitudes greater than 2,000 feet (610 meters) must be shipped from the factory or from a factory authorized conversion station with the heating input derated by 10% so as to operate properly in altitudes from 2,000 - 4,500 feet (610 ­1,373 meters).
Condensate Drain

Furnace Section Controls and Ignition System
Normal Furnace Operating Sequence
This unit is equipped with a two stage integrated direct spark ignition control.
Normal Heat Mode
Call For First Stage (low fire) Only:
1 Zone thermostat contacts close, a call for first stage (low
fire) heat is initiated.
2 Control runs self check.
3 Control checks the high-limit switch for normally closed
contacts, each pressure switch for normally open contacts, and all flame rollout switches for continuity.
4 Control energizes each low-fire inducer.
5 Control checks each low-fire pressure switch for closure.
6 If each low-fire pressure switch is closed, the control
starts a 30 second prepurge. If either low-fire pressure switch is still open after 180 seconds, the high-fire inducers will be energized until closure.
7 After prepurge timeout, control initiates spark for 2
seconds minimum, 7 second maximum ignition trial, initiates 120 second, second stage (high fire) warm up timing.
8 Control detects flame, de-energizes spark and initiates 45
second delay on blower timing.
9 After a fixed 45 seconds indoor blower delay on, the
control energizes the indoor blower.
10 After a fixed 120 seconds second stage warmup period
control checks thermostat input. If only W1 is called for, W2 is de-energized and the control starts a 30 second off delay on the W2 inducer.
11 After fixed 30 seconds the W2 inducer is de-energized.
12 Control enters normal operating loop where all inputs are
continuously checked.
13 Zone thermostat is satisfied.
14 Control de-energizes gas valve.
15 Control senses loss of flame.
16 Control initiates 5 second inducer postpurge and 90
second indoor blower delay off.
17 Control de-energizes inducer blower.
18 Control de-energizes indoor blower.
19 Control in the stand by mode with solid red LED.
Call For Second Stage, After First Stage Established; Starting from A.11:
1 If a call for second stage (high fire) is initiated after a call
for first stage heat is established, the control energizes the W2 inducer and energizes the second stage of the gas valve.
2 Control enters normal operating loop where all inputs are
continuously checked.
Second Stage Satisfied; First Stage Still Called For; Starting From B.3:
1 Once the call for second stage is satisfied, the control
starts a 30 second off delay on W2 inducer and reduces the gas valve to first stage.
2 Control enters normal operating loop where all inputs are
continuously checked.
First Stage Satisfied:
1 Zone thermostat is satisfied.
2 Control de-energizes gas valve.
3 Control senses loss of flame.
4 Control initiates 5 second inducer postpurge and 90
second indoor blower delay off.
5 Control de-energizes inducer blower.
6 Control de-energizes indoor blower.
7 Control in the stand by mode with solid red LED.
First Stage and Second Stage Called Simultaneously:
1 Zone thermostat contacts close, a call for first stage (low
fire) and second stage (high fire) heat is initiated.
2 Control runs self check.
3 Control checks the high-limit switch for normally closed
contacts, each pressure switch for normally open contacts, and all flame rollout switches for continuity.
4 Control energizes each low-fire inducer.
5 Control checks each pressure switch for closure.
6 If each low-fire pressure switch is closed, the control
starts a 30 second prepurge. If either switch is still open after 180 seconds, the high-fire inducers will be energized until closure.
7 After prepurge timeout, control initiates spark for 2
seconds minimum, 7 second maximum ignition trial, and initiates 120 second stage warm up timing.
8 Control detects flame, de-energizes spark and starts a 45
second indoor blower delay on timing.
9 After a fixed 45 seconds indoor blower delay on, the
control energizes the indoor blower.
10 After a fixed 120 seconds second stage warmup period
control checks the thermostat input. If W1 and W2 is present control enters normal operating loop where all inputs are continuously checked.
First Stage and Second Stage Removed Simultaneously:
1 Upon a loss of W1 and W2 the gas valve is de-energized.
2 Upon a loss of flame, each inducer will complete a 5
second postpurge and the indoor blower will complete a 90 second delay off.
3 Control in the stand by mode with solid red LED.
The integrated control is a four-ignition system.
After a total of four cycles without sensing main burner flame, the system goes into a 100% lockout mode. After one hour, the ignition control repeats the prepurge and ignition cycles for 4 tries and then go into 100% lockout mode again. It continues this sequence of cycles and lockout each hour until
Page 30
30 IM 862
ignition is successful or power is interrupted. During the lockout mode, neither the ignitor or gas valve will be energized until the system is reset by turning the thermostat to the “OFF” position or interrupting the electrical power to the unit for 3 seconds or longer. The induced draft blower and main burner will shut off when the thermostat is satisfied.
The circulating air blower will start and run on the heating speed if the thermostat fan switch is in the “ON” position.
The integrated furnace control is equipped with diagnostic LED. The LED is lit continuously when there is power to the control, with or without a call for heat. If the LED is not lit, there is either no power to the control or there is an internal component failure within the control, and the control should be replaced.
If the control detects the following failures, the LED will flash on for approximately 1/4 second, then off for 3/4 second for designated failure detections.
1 Flash: Failed to detect flame within the four tries for
ignition.
2 Flash: Pressure switch or induced draft blower problem
detected.
3 Flash: High limit or auxiliary limit open.
4 Flash: Flame sensed and gas valve not energized or flame
sensed with no “W” signal.
5 Flash: Overtemperature switch open.

Limit Control
The supply air high temperature limit cut-off is set at the factory and cannot be adjusted. It is calibrated to prevent the air temperature leaving the furnace from exceeding the maximum outlet air temperature.
IMPORTANT: Replace this control only with the identical replacement part.
System Operating Information
Advise The Customer
1 Change the air filters regularly. The heating system
operates better, more efficiently and more economically.
2 Except for the mounting platform, keep all combustible
articles three feet from the unit and exhaust system.
3 IMPORTANT: Replace all blower doors and compartment
cover after servicing the unit. Do not operate the unit without all panels and doors securely in place.
4 Do not allow snow or other debris to accumulate in the
vicinity of the unit.
Furnace Section Maintenance
The unit’s furnace should operate for many years without excessive scale build-up in flue passageways; however, it is recommended that a qualified installer, service agency, or the gas supplier annually inspect the flue passageways, the exhaust system and the burners for continued safe operation, paying particular attention to deterioration from corrosion or other sources.
If during inspection the flue passageways and exhaust system are determined to require cleaning, the following procedures should be followed (by a qualified installer, service agency,
or gas supplier):
1 Turn off the electrical power to the unit and set the
thermostat to the lowest temperature.
2 Shut off the gas supply to the unit either at the meter
or at manual valve in the supply piping.
3 Remove the furnace controls access panel and the control
box cover.
4 Disconnect the gas supply piping from the gas valve.
5 Disconnect the wiring to the induced draft blower motor,
gas valve, flame sensor, and flame roll-out control, and ignitor cable. Mark all wires disconnected for proper
reconnection.
6 Remove the screws (4) connecting the burner tray to the
heat exchanger mounting panel.
7 Remove the burner tray and the manifold assembly from
the unit.
8 Remove the screws (10) connecting the two induced draft
blowers to the collector box and screws (12) connecting the inducer mounting plate to the heat exchanger center panel. Remove the induced draft blower and the collector box from the unit.
9 Remove the turbulators from inside the heat exchangers by
inserting the blade of a screwdriver under the locking tabs. Pop the tabs out of the expanded grooves of the heat exchanger. Slide the turbulators out of the heat exchangers.
10 Direct a water hose into the outlet of the heat exchanger
top. Flush the inside of each heat exchanger tube with water. Blow out each tube with air to remove excessive moisture.
11 Reassemble (steps 1 through 9 in reverse order). Be
careful not to strip out the screw holes used to mount the collector box and inducer blower. Replace inducer blower gasket and collector box gasket with factory replacements if damaged.
The manufacturer recommends that a qualified installer, service agency or the gas supplier visually inspect the burner flames for the desired flame appearance at the beginning of the heating season and approximately midway in heating season.
DO NOT JUMPER THIS DEVICE! DO NOT reset the over­temperature control without taking corrective action to assure that an adequate supply of combustion air is maintained under all conditions of operation. Failure to do so can result in carbon monoxide poisoning or death. Replace this control only with the identical replacement part.

The manufacturer also recommends that a qualified installer, service agency or the gas supplier clean the flame sensor with steel wool at the beginning of the heating season.
Lubrication
IMPORTANT: DO NOT attempt to lubricate the bearings on the
blower motor or the induced draft blower motor. Addition of lubricants can reduce the motor life and void the warranty.
The blower motor and induced draft blower motor are prelubricated by the manufacturer and do not require further attention.
A qualified installer, service agency or the gas supplier must periodically clean the motors to prevent the possibility of overheating due to an accumulation of dust and dirt on the windings or on the motor exterior. And, as suggested elsewhere in these instructions, the air filters should be kept clean because dirty filters can restrict air flow and the motor depends upon sufficient air flowing across and through it to prevent overheating.
Cooling Section Maintenance
It is recommended that at the beginning of each cooling season a qualified installer or service agency inspect and clean the cooling section of this unit. The following areas should be addressed: evaporator coil. condenser coil, condenser fan motor and venturi area.
To inspect the evaporator coil:
1 Open the control/filter access panel and remove filters.
Also, remove blower access panel. In downflow applications remove the horizontal return to gain access.
2 Shine a flashlight on the evaporator coil (both sides) and
inspect for accumulation of lint, insulation, etc.
3 If coil requires cleaning, follow the steps shown below.
Cleaning Evaporator Coil
1 The coil should be cleaned when it is dry. If the coil is
coated with dirt or lint, vacuum it with a soft brush attachment. Be careful not to bend the coil fins.
2 If the coil is coated with oil or grease, clean it with a mild
detergent-and-water solution. Rinse the coil thoroughly with water. IMPORTANT: Do not use excessive water
pressure. Excessive water pressure can bend the fins and tubing of the coil and lead to inadequate unit performance. Be careful not to splash water excessively into unit.
3 Inspect the drain pan and condensate drain at the same
time the evaporator coil is checked. Clean the drain pan by flushing with water and removing any matters of obstructions which may be present.
4 Go to next section for cleaning the condenser coil.
Cleaning Condenser Coil, Condenser Fan, Circulation Air Blower and Venturi
1 Remove the compressor access panel. Disconnect the
wires to the condenser fan motor in the control box (see wiring diagram).
2 The coil should be cleaned when it is dry. If the coil is
coated with dirt or lint, vacuum it with a soft brush attachment. Be careful not to bend the coil fins.
3 If the coil is coated with oil or grease, clean it with a mild
detergent-and-water solution. Rinse the coil thoroughly with water. IMPORTANT: Do not use excessive water
pressure. Excessive water pressure can bend the fins and tubing of the coil and lead to inadequate unit performance. Be careful not to splash water excessively into unit.
4 The venturi should also be inspected for items of
obstruction such as collections of grass, dirt or spider webs. Remove any that are present.
5 Inspect the circulating air blower wheel and motor for
accumulation of lint, dirt or other obstruction and clean it necessary. Inspect the blower motor mounts and the blower housing for loose mounts or other damage. Repair or replace if necessary.
Re-assembly
1 Reconnect fan motor wires per the wiring diagram
attached to the back of the cover.
2 Close the filter control and replace the blower/evaporator
coil access panels.
3 Replace the control box cover.
4 Restore electrical power to the unit and check for proper
operation, especially the condenser fan motor.
