Combustion and Ventilation Air Requirements
WARNING
To avoid property damage, personal injury or death, sufficient fresh air for proper combustion and ventilation of flue gas must be supplied. Most homes require outside air be supplied into the furnace area.
Improved construction and additional insulation in buildings have reduced heat loss by reducing air infiltration and escape around doors and windows. These changes have helped in reducing heating/cooling costs but have created a problem supplying combustion and ventilation air for gas fired and other fuel burning appliances. Appliances that pull air out of the house (clothes dryers, exhaust fans, fireplaces, etc.) increase the problem by starving appliances for air.
House depressurization can cause back drafting or improper combustion of gas- fired appliances, thereby exposing building occupants to gas combustion products that could include carbon monoxide.
If this furnace is to be installed in the same space with other gas appliances, such as a water heater, ensure there is an adequate supply of combustion and ventilation air for all appliances. Refer to the latest edition of the National Fuel Gas Code NFPA 54/ANSI Z223.1 or CAN/CSA B149 Installation Codes or applicable provisions of the local building codes for determining the combustion air requirements for the appliances.
This furnace must use indoor air for combustion. It cannot be installed as a direct vent (i.e., sealed combustion) furnace.

8

Most homes will require outside air be supplied to the furnace area by means of ventilation grilles or ducts connecting directly to the outdoors or spaces open to the outdoors such as attics or crawl spaces.
Category I Venting (Vertical Venting)
WARNING
To prevent possible personal injury or death due to asphyxiation, this furnace must be Category I vented. Do not vent using Category III venting.
Category I Venting is venting at a non-positive pressure. A furnace vented as Category I is considered a fan-assisted appliance and the vent system does not have to be “gas tight”. NOTE: Gas furnaces with induced draft blowers draw products of combustion through a heat exchanger allowing, in some instances, common venting with natural draft appliances (i.e. water heaters). All installations must be vented in accordance with National Fuel Gas Code NFPA 54/ANSI Z223.1 – latest edition.
NOTE: The vertical height of the Category I venting system must be at least as great as the horizontal length of the venting system.

WARNING
To prevent possible personal injury or death due to asphyxiation, common venting with other manufacturer’s induced draft appliances is not allowed.

The minimum vent diameter for the Category I venting sys-

tem is as shown:

Masonry Chimneys
WARNING
Possibility of property damage, personal injury or death damaging condensation can occur inside masonry chimneys when a single fan-assisted Category I appliance (80% AFUE furnace) is vented without adequate dilution air. Do not connect an 80% furnace to a masonry chimney unless the furnace is common vented with a draft hood equipped appliance or the chimney is lined with a metal liner or Type B metal vent. All installations using masonry chimneys must be sized in accordance with appropriate venting tables. If an 80% furnaces common vented with a draft hood equipped appliance, the potential for condensation damage may still exist with extremely cold conditions, long vent connectors, exterior chimneys, or any combination of these conditions. The risk of condensation damages is best avoided by using masonry chimney as a pathway for properly sized metal liner or Type B metal vent.
Masonry Chimney Terminations A masonry chimney used as a vent for gas fired equipment must extend at least three feet above the highest point where it passes through the roof. It must extend at least two feet higher than any portion of a building within a horizontal distance of 10 feet. In addition, the chimney must terminate at least three feet above any forced air inlet located within 10 feet. The chimney must extend at least five above the highest connected equipment draft hood outlet or flue collar.

IMPORTANT NOTE: To avoid possible equipment malfunction, route the low voltage wires to avoid interference with filter removal or other maintenance.
WARNING
HIGH VOLTAGE!
To avoid risk of injury, electrical shock or death, the furnace must be electrically grounded in accordance with local codes or in their absence, with the latest edition of the National Electric Code.
To ensure proper unit grounding, the ground wire should run from the furnace ground screw located inside the furnace junction box all the way back to the electrical panel. NOTE: Do not use gas piping as an electrical ground. To confirm proper unit grounding, turn off the electrical power and perform the following check.
1. Measure resistance between the neutral (white) connection and one of the burners.
2. Resistance should measure 10 ohms or less.

INLET GAS SUPPLY PRESSURE Natural Gas Minimum: 4.5″ w.c. Maximum: 10.0″ w.c.
Propane Gas Minimum: 11.0″ w.c. Maximum: 13.0″ w.c.
NOTE: Adjusting the minimum supply pressure below the limits in the above table could lead to unreliable ignition. Gas input to the burners must not exceed the rated input shown on the rating plate. Overfiring of the furnace can result in premature heat exchanger failure. Gas pressures in excess of 13 inches water column can also cause permanent damage to the gas valve.
At all altitudes, the manifold pressure must be within 0.3 inches w.c. of that listed in the Specification Sheet applicable to your model for the fuel used. At all altitudes and with either fuel, the air temperature rise must be within the range listed on the furnace nameplate. Should this appliance be converted to LP, refer to the instructions included in the factory authorized LP conversion kit.
High Altitude Derate
When this furnace is installed at high altitude, the appropriate High Altitude orifice kit must be applied. This is required due to the natural reduction in the density of both the gas fuel and combustion air as altitude increases. The kit will provide the proper design certified input rate within the specified altitude range. High altitude kits are purchased according to the installation altitude and usage of either natural or propane gas. Consult the furnace Specification Sheet for appropriate kits.

This furnace is equipped with a blower door interlock switch which interrupts unit voltage when the blower door is opened for servicing. Do not defeat this switch.
Gas Supply and Piping
The furnace rating plate includes the approved furnace gas input rating and gas types. The furnace must be equipped to operate on the type of gas applied. This includes any conversion kits required for alternate fuels and/or high altitude.
CAUTION
To prevent unreliable operation or equipment damage, the inlet gas supply pressure must be as specified on the unit rating plate with all other household gas fired appliances operating.
Inlet gas supply pressures must be maintained within the ranges specified in the following table. The supply pressure must be constant and available with all other household gas fired appliances operating. The minimum gas supply pressure must be maintained to prevent unreliable ignition. The maximum must not be exceeded to prevent unit overfiring.
NOTE: Do not remove the gas valve inlet plug before the gas line is installed. Replace if water or debris has been introduced.

Do not derate the furnace by adjusting the manifold pressure to a lower pressure than specified on the furnace rating plate. The combination of the lower air density and a lower manifold pressure will prohibit the burner orifice from drawing the proper amount of air into the burner. This may cause incomplete combustion, flashback, and possible yellow tipping.
In some areas the gas supplier may artificially derate the gas in an effort to compensate for the effects of altitude. If the gas is artificially derated, the appropriate orifice size must be determined based upon the BTU/ft3 content of the derated gas and the altitude. Refer to the National Fuel Gas Code, NFPA 54/ANSI Z223.1, and information provided by the gas supplier to determine the proper orifice size.
A different pressure switch may be required at high altitude regardless of the BTU/ft3 content of the fuel used. Consult the furnace Specification Sheet for pressure switch.
WARNING
Possible property damage, personal injury or death may occur if the correct conversion kits are not installed. The appropriate kits must be applied to ensure safe and proper furnace operation. All conversions must be performed by a qualified installer or service agency.

If converting to LP gas, it is recommended that an LPLP0* kit also be installed. The use of this kit will prevent the furnace from firing when the LP gas supply pressure is too low to support proper combustion.
Gas Valve This unit is equipped with a 24 volt gas valve controlled during furnace operation by the integrated control module. As shipped, the valve is configured for natural gas. The valve is field convertible for use with propane gas by replacing the regulator spring with a propane gas spring from an appropriate manufacturer’s propane gas conversion kit. Taps for measuring the gas supply pressure and manifold pressure are provided on the valve.
The gas valve has a manual ON/OFF control located on the valve itself. This control may be set only to the “ON” or “OFF” position. Refer to the lighting instructions label or Startup Procedure & Adjustment for use of this control during start up and shut down periods.
Gas Piping Connections When sizing gas lines, be sure to include all appliances which will operate simultaneously.
The gas piping supplying the furnace must be properly sized based on the gas flow required, specific gravity of the gas, and length of the run. The gas line installation must comply with local codes, or in their absence, with the latest edition of

The following stipulations apply when connecting gas piping. · Gas piping must be supported external to the furnace cabinet so that the weight of the gas line does not distort the burner rack, manifold or gas valve. · Use black iron or steel pipe and fittings for the building piping. · Use pipe joint compound on male threads only. Pipe joint compound must be resistant to the action of the fuel used. · Use ground joint unions. · Install a drip leg to trap dirt and moisture before it can enter the gas valve. The drip leg must be a minimum of three inches long. · Use two pipe wrenches when making connection to the gas valve to keep it from turning. The orientation of the gas valve on the manifold must be maintained as shipped from the factory. · Install a manual shutoff valve between the gas meter and unit within six feet of the unit. If a union is installed, the union must be downstream of the manual shutoff valve, between the shutoff valve and the furnace. · Tighten all joints securely. · Connect the furnace to the building piping by one of the following methods: ­ Rigid metallic pipe and fittings. ­ Semi-rigid metallic tubing and metallic fittings. Aluminum alloy tubing must not be used in exterior locations. ­ Use listed gas appliance connectors in accordance with their instructions. Connectors must be fully in the same room as the furnace. ­ Protect connectors and semi-rigid tubing against physical and thermal damage when installed. Ensure aluminum-alloy tubing and connectors are coated to protect against external corrosion when in contact with masonry, plaster, or insulation, or subjected to re-

To prevent property damage or personal injury due to fire, the following instructions must be performed regarding gas connections, pressure testing, location of shutoff valve and installation of gas piping.
NOTE: Never exceed specified pressures for testing. Higher pressure may cause gas valve failure.
Disconnect this unit and shutoff valve from the gas supply piping system before pressure testing the supply piping system with pressures in excess of ½ psig (3.48 kPa).
This unit must be isolated from the gas supply system by closing its manual shutoff valve before pressure testing of gas supply piping system with test pressures equal to or less than ½ psig (3.48 kPa). Propane Gas Tanks and Piping
A gas detecting warning system is the only reliable way to detect a propane gas leak. Rust can reduce the level of odorant in propane gas. Do not rely on your sense of smell. Contact a local propane gas supplier about installing a gas detecting warning system. If the presence of gas is suspected, follow the instructions on Page 3 of this manual.
All propane gas equipment must conform to the safety standards of the National Board of Fire Underwriters, NBFU Manual 58.
For satisfactory operation, propane gas pressure must be 10 inch WC at the furnace manifold with all gas appliances in operation. Maintaining proper gas pressure depends on three main factors:
1. Vaporization rate, depending on temperature of the liquid, and “wetted surface” area of the container or containers.
2. Proper pressure regulation (Two-stage regulation is recommended for both cost and efficiency).
3. Pressure drop in lines between regulators, and between second stage regulator and the appliance. Pipe size will depend on length of pipe run and total load of all appliances.

A closed return duct system must be used, with the return duct connected to the furnace. NOTE: Ductwork must never be attached to the back of the furnace. For installations requiring more than 1800 CFM, use a bottom return or two sided return. Supply and return connections to the furnace may be made with flexible joints to reduce noise transmission. To prevent the blower from interfering with combustion air or draft when a central return is used, a connecting duct must be installed between the unit and the utility room wall. A room, closet, or alcove must not be used as a return air chamber. When the furnace is used in connection with a cooling unit, the furnace should be installed in parallel with or on the upstream side of the cooling unit to avoid condensation in the heating element. With a parallel flow arrangement, the dampers or other means used to control the flow of air must 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 the full heat or cool position.
When the furnace is installed without a cooling coil, it is recommended that a removable access panel be provided in the outlet air duct. This opening shall be accessible when the furnace is installed and shall be of such a size that the heat exchanger can be viewed for visual light inspection or such that a sampling probe can be inserted into the air stream. The access panel must be made to prevent air leaks when the furnace is in operation.
When furnace duct(s) supply air outside the space containing the furnace, a return air duct must terminate in the same space as the supply duct and be sealed to the furnace casing.
When the furnace is heating, the temperature of the return air entering the furnace must be between 55°F and 100°F.

Checking Duct Static
Refer to your furnace rating plate for the maximum ESP (external duct static) rating.

14

Total external static refers to static pressure created by all components external to the furnace cabinet. Cooling coils, filters, ducts, grilles, registers must all be considered when reading your total external static pressure. The supply duct pressure must be read between the furnace and the cooling coil. This reading is usually taken by removing the “A” shaped block off plate from the end on the coil; drilling a test hole in it and reinstalling the block off plate. Take a duct static reading at the test hole. Tape up the test hole after your test is complete. The negative pressure must be read between the filter and the furnace blower.
Too much external static pressure will result in insufficient air that can cause excessive temperature rise. This can cause limit switch tripping and heat exchanger failure.
To determine total external duct static pressure, proceed as follows:
4. With clean filters in the furnace, use a manometer to measure the static pressure of the return duct at the inlet of the furnace. (Negative Pressure)
5. Measure the static pressure of the supply duct. (Positive Pressure)
6. The difference between the two numbers is .4″ w.c.
Example: static reading from return duct = -.1″ w.c.

Filters – Read This Section Before Installing The Return Air Ductwork
Filters must be used with this furnace. Discuss filter maintenance with the building owner. Filters do not ship with this furnace, but must be provided by the installer. Filters must comply with UL900 or CAN/ULCS111 standards. Damage or repairs due to the installation of the furnace without filters is not covered under the warranty.
Upright Installations
Depending on the installation and/or customer preference, differing filter arrangements can be applied. Filters can be installed in the central return register or a side panel external filter rack kit (upflows), or the ductwork above a downflow furnace. As an alternative, a media air filter or electronic air cleaner can be used as the primary filter. Horizontal Installations
Filters must be installed in either the central return register or in the return air duct work.
Circulation Air Filters

static reading from supply duct = .3″ w.c.

total external static pressure on this system = .4″ w.c.

NOTE: Both readings may be taken simultaneously and read directly on the manometer if so desired. If an air
conditioner coil or Electronic Air Cleaner is used in conjunction with the furnace, the readings must also include
these components, as shown in the following drawing.

7. Consult proper tables for the quantity of air.

If the total external static pressure exceeds the maximum listed on the furnace rating plate, check for closed dampers, registers, undersized or poorly laid out duct work.

Fossil Fuel Applications This furnace can be used in conjunction with a heat pump in a fossil fuel application. A fossil fuel application refers to a combined gas furnace and heat pump installation which uses an outdoor temperature sensor to determine the most cost efficient means of heating (heat pump or gas furnace).
A heat pump thermostat is required to properly use a single-stage furnace in conjunction with a heat pump. Refer to the fossil fuel kit installation instructions for additional thermostat requirements.
Strictly follow the wiring guidelines in the fossil fuel kit installation instructions. All furnace connections must be made to the furnace two-stage integrated control module and the “FURNACE” terminal strip on the fossil fuel control board.

Important Note: Wiring routing must not interfere with circulator blower operation, filter removal or routine maintenance. Low voltage connections can be made through either the
right or left side panel. Thermostat wiring entrance holes
are located in the blower compartment. The following figure shows connections for a “heat/cool system”.

Two furnaces of the same model may be twinned. The integrated control board has a 3/16″ terminal labeled “TWIN” located beside the low voltage thermostat connection strip. Twinning allows simultaneous operation of two furnaces and forces the indoor blower motors of each furnace to operate synchronously into a common duct system. Using the twinning function will require only field installed wiring with no

details of 115 Volt and 24 Volt wiring.

NOTE: Each furnace must be connected to it’s own 115 VAC

power supply. The L1 connection to each furnace must be in

phase (connected to circuit breakers on the same 115 VAC

service panel phase leg). To verify that the furnaces are in

phase, check from L1 to L1 on each furnace with a voltme-

ter. If the furnaces are in phase, the voltage between both

furnaces will be ZERO.

Low Voltage Humidifier The furnace integrated control module is equipped with a low voltage terminal for providing power to an optional field-supplied 24 volt humidifier. The 24V HUM terminal is energized any time the draft inducer is powered. See connection diagram below.
NOTE: This is a 24 volt circuit only, the common connection must be on C terminal of the low voltage terminal strip (where thermostat wires are connected). Wiring for this circuit must NOT be connected to the line N location where line voltage neutral wires are connected.

If it is necessary for the installer to supply additional line voltage wiring to the inside of the furnace, the wiring must conform to all local codes, and have a minimum temperature rating of 105°C. All line voltage wire splices must be made inside the furnace junction box.
The integrated control module humidifier terminal (HUM H) is energized with 115 volts whenever the induced draft blower is energized. The integrated control module electronic air cleaner terminal (EAC H) is energized with 115 volts whenever the circulator blower is energized. This terminal can also be used to provide 115 volt power to a humidifier transformer. The remaining primary transformer wire would be connected to the Line N on the control board.

Maintenance
WARNING
To avoid electric shock, injury or death, disconnect electrical power before performing any maintanence. If you must handle the igniter, handle with care. Touching the igniter element with bare fingers, rough handling or vibration could damage the igniter resulting in premature failure. Only a qualified servicer should ever handle the igniter.
Annual Inspection The furnace should be inspected by a qualified installer, or service agency at least once per year. This check should be performed at the beginning of the heating season. This will ensure that all furnace components are in proper working order and that the heating system functions appropriately. Pay particular attention to the following items. Repair or service as necessary.
· Flue pipe system. Check for blockage and/or leakage. Check the outside termination and the connections at and internal to the furnace.
· Heat exchanger. Check for corrosion and/or buildup within the heat exchanger passageways.
· Burners. Check for proper ignition, burner flame, and flame signal.
· Wiring. Check electrical connections for tightness and/ or corrosion. Check wires for damage.
· Filters.
Filters
CAUTION
To ensure proper unit performance, adhere to the filter sizes given in the recommended Minimum Filter Size Table or Specification Sheet applicable to your model.

To remove filters from an external filter rack in an upright upflow installation, follow the directions provided with external filter rack kit.
Horizontal Unit Filter Removal Filters in horizontal installations are located in the central return register or the ductwork near the furnace.
To remove: 1. Turn OFF electrical power to furnace. 2. Remove filter(s) from the central return register or ductwork. 3. Replace filter(s) by reversing the procedure for removal. 4. Turn ON electrical power to furnace.
Media Air Filter or Electronic Air Cleaner Removal
Follow the manufacturer’s directions for service.
Burners Visually inspect the burner flames periodically during the heating season. Turn on the furnace at the thermostat and allow several minutes for flames to stabilize, since any dislodged dust will alter the flames normal appearance. Flames should be stable, quiet, soft, and blue (dust may cause orange tips but they must not be yellow). They should extend directly outward from the burners without curling, floating, or lifting off. Flames must not impinge on the sides of the heat exchanger firing tubes.
Induced Draft and Circulator Blowers The bearings in the induced draft blower and circulator blower motors are permanently lubricated by the manufacturer. No further lubrication is required. Check motor windings for accumulation of dust which may cause overheating. Clean as necessary.

Filter Maintenance
Improper filter maintenance is the most common cause of inadequate heating or cooling performance. Filters should be cleaned (permanent) or replaced (disposable) as required.
Filter Removal
Depending on the installation, differing filter arrangements can be applied. Filters can be installed in either the central return register or a side panel external filter rack (upflow only). A media air filter or electronic air cleaner can be used as an alternate filter. Follow the filter sizes given in the Recommended Minimum Filter size table to ensure proper unit performance.

Flame Sensor (Qualified Servicer Only)
Under some conditions, the fuel or air supply can create a nearly invisible coating on the flame sensor. This coating acts as an insulator causing a drop in the flame sense signal. If the flame sense signal drops too low the furnace will not sense flame and will lock out. The flame sensor should be carefully cleaned by a qualified servicer using steel wool. Following cleaning, the flame sense signal should be as indicated in the Specifications Sheet.
Flue Passages (Qualified Servicer Only)
The heat exchanger flue passageways should be inspected at the beginning of each heating season.

Before Leaving an Installation

· Cycle the furnace with the thermostat at least three times. Verify cooling and fan only operation.
· Review the Owner’s Manual with the homeowner and
discuss proper furnace operation and maintenance.
· Leave literature packet near furnace.
