OCA TION REQUIREMENTS

& C

ONSIDERA TIONS

Follow the instructions listed below and the guidelines provided in the Combustion and Ventilation Air Requirements section when selecting a furnace location.

WARNING

PREVENT POSSIBLE EQUIPM EN T DAMAGE, PROPERTY DAMAGE PERSONAL INJURY OR DEATH, THE FOLLOWING BULLET POINTS MUST BE OBSERVED WHEN INSTALLING THIS UNIT

WARNING

• Centrally locate the furnace with respect to the proposed or existing air distribution system.

• Ensure the temperature of the return air entering the furnace is between 55°F and 100°F when the furnace is heating.

• Provide provisions for venting combustion products outdoors through a proper venting system. Special consideration should be given to vent/flue pipe routing and combustion air intake pipe when applicable. Refer to V ent/Flue Pipe and Combustion Air Pipe -T ermination Locations for appropriate termination locations and to determine if the piping system from furnace to termination can be accomplished within the guidelines given. NOTE: The length of flue and/or combustion air piping can be a limiting factor in the location of the furnace.

• Locate the furnace so condensate flows downwards to the drain. Do not locate the furnace or its condensate drainage system in any area subject to below freezing temperatures without proper freeze protection. Refer to Condensate Drain Lines and T rap for further details.

• Ensure adequate combustion air is available for the furnace. Improper or insufficient combustion air can expose building occupants to gas combustion products that could include carbon monoxide. Refer to

Combustion and V entilation Air Requirements.

• Set the furnace on a level floor to enable proper condensate drainage. If the floor becomes wet or damp at times, place the furnace above the floor on a concrete base sized approximately 1-1/2" larger than the base of the furnace. Refer to the Horizontal Applications and Considerations for leveling of horizontal furnaces.

• Ensure upflow or horizontal furnaces are not installed directly on carpeting, or any other combustible material. The only combustible material allowed is wood.

• Exposure to contaminated combustion air will result in safety and performance-related problems. Do not install the furnace where the combustion air is exposed to the following substances:

permanent wave solutions carbon tetrachloride deicing salts or chemicals cleaning solutions (such as perchloroethylene) paint removers cements and glues chlorinated waxes or cleaners water softening chemicals halogen type refrigerants chlorine-based swimming pool chemicals printing inks varnishes

hydrochloric acid antistatic fabric softeners for clothes dryers

• Seal off a non-direct vent furnace if it is installed near an area frequently contaminated by any of the above substances. This protects the non-direct vent furnace from airborne contaminants. To ensure that the

enclosed non-direct vent furnace has an adequate supply of combustion air , vent from a nearby uncontaminated room or from outdoors. Refer to the Combustion and Ventilation Air Requirements for details.

• If the furnace is used in connection with a cooling coil unit, install the furnace upstream or in parallel with the cooling coil unit. Premature heat exchanger failure will result if the cooling unit is placed ahead of the furnace.

For vertical (upflow or downflow) applications, the minimum cooling coil width shall not be less than furnace width minus 1”. Additionally, a coil installed above an upflow furnace or under a counterflow furnace may be the same width as the furnace or may be one size larger than the furnace. Example:

a “C” width coil may be installed with a “B” width furnace.

For upflow applications, the front of the coil and furnace must face the same direction.

• If the furnace is installed in a residential garage, position the furnace so that the burners and ignition source are located not less than 18 inches (457 mm) above the floor. Protect the furnace from physical damage by vehicles.

• If the furnace is installed horizontally , ensure the access doors are not on the “up/top” or “down/bottom” side of the furnace.

• Do not connect this furnace to a chimney flue that serves a separate appliance designed to burn solid fuel.

• On Counterflow Installations, the air conditioning coil must be downstream on the supply (positive) side of the furnace heat exchanger .

• Counterflow Installation over a noncombustible floor. Before setting the furnace over the plenum opening, ensure the surface around the opening is smooth and level. A tight seal should be made between the furnace base and floor by using a silicone rubber caulking compound or cement grout.

• Counterflow Installation over a combustible floor. If installation over a combustible floor becomes necessary , use an accessory subbase (see Specification Sheet applicable for your model for details.) A special accessory subbase must be used for upright counterflow unit installations over any combustible material including wood. Refer to subbase instructions for installation details. Follow the instructions with the subbase for proper installation. Do not install the furnace directly on carpeting, tile, or other combustible material other than wood flooring. (NOTE: The subbase will not be required if an air conditioning coil is installed between the supply air opening on the furnace and the floor .)

CLEARANCES AND ACCESSIBILITY

NOTES:

• For servicing or cleaning, a 24” front clearance is required.

• Unit connections (electrical, flue and drain) may necessitate greater clearances than the minimum clearances listed above.

• In all cases, accessibility clearance must take precedence over clearances from the enclosure where accessibility clearances are greater .

NOTES:

• For servicing or cleaning, a 24” front clearance is required.

A furnace installed in a confined space (i.e., a closet or utility room) must have two ventilation openings with a total minimum free area of 0.25 square inches per 1,000 BTU/hr of furnace input rating. Refer to Specification Sheet applicable to your model for minimum clearances to combustible surfaces. One of the ventilation openings must be within 12 inches of the top; the other opening must be within 12 inches of the bottom of the confined space. In a typical construction, the clearance between the door and door frame is usually adequate to satisfy this ventilation requirement.

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

If resizing is required on any portion of the venting system, use the appropriate table in Appendix G in the latest edition of the National Fuel Gas Code ANSI Z223.1 and/or CSA B149.1-15 Installation Codes.

EXISTING FURNACE REMOVAL

NOTE: When an existing furnace is removed from a venting sys-

tem serving other appliances, the venting system may be too large to properly vent the remaining attached appliances.

The following vent testing procedure is reproduced from the

American National Standard/National Standard of Canada for Gas-Fired Central F urnaces ANSI Z21.47, CSA-2.3 latest edition Section 1.23.1.

The following steps shall be followed with each appliance connected to the venting system placed in operation, while any 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 by the National Fuel Gas Code, ANSI Z223.1 or the Natural Gas and Propane Installation Code, CSA B149.1-15 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.

THERMOSTAT LOCATION

The thermostat should be placed approximately five feet from the floor on a vibration-free, inside wall in an area having good air circulation. Do not install the thermostat where it may be influenced by any of the following:

• Drafts, or dead spots behind doors, in corners, or under cabinets.

• Hot or cold air from registers.

• Radiant heat from the sun.

• Light fixtures or other appliances.

• Radiant heat from a fireplace.

• Concealed hot or cold water pipes, or chimneys.

8. 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 Z223.1/ NFP A 54 and/or National Gas and P ropane Installation Code CSA B149.1-15.

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 the other appliances. Refer to the latest edition of the National Fuel Gas Code NFP A 54/ANSI Z223.1 or CAN/CSA B149.1-15 Installation Codes or applicable provisions of the local building codes for determining the combustion air requirements for the appliances.

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.

FRONT COVER PRESSURE SWITCH TUBE LOCATION

When a furnace is installed horizontally with left side down, the front cover pressure switch tube must be re-locaed to he lower port of the collector box cover .

1. Remove tubefrom front cover pressure switch and collector box cover .

2. Remove rubber plug from bottom collector box port and install on top of collector box port.

3. Locate 24’’ x 1/4’’ tube in bag assembly.

4. Install one end on front cover pressure switch.

5. Route tube to lower port on collector box cover and cut off excess tubing.

DRAIN TRAP AND LINES

In horizontal applications the condensate drain trap is secured to the furnace side panel, suspending it below the furnace. A minimum clearance of 5.5” below the furnace must be provided for the drain trap. Additionally, the appropriate downward piping slope must be maintained from the drain trap to the drain location. Refer to Condensate Drain Trap and Lines for further de- tails. If the drain trap and drain line will be exposed to temperatures near or below freezing, adequate measures must be taken to prevent condensate from freezing.

HORIZONTAL FURNACE LEVELING

Leveling ensures proper condensate drainage from the heat exchanger. For proper flue pipe drainage, the furnace must be level lengthwise from end to end. The furnace should have a slight tilt from back to front with the access doors downhill from the back panel approximately 1/2 to 3/4 inches. The slight tilt allows the heat exchanger condensate, generated in the recuperator coil, to flow forward to the recuperator coil front cover.

ALTERNATE ELECTRICAL AND GAS LINE CONNECTIONS

This furnace has provisions allowing for electrical and gas line connections through either side panel. In horizontal applications the connections can be made either through the “top” or “bottom” of the furnace.

DRAIN PAN

A drain pan must be provided if the furnace is installed above a conditioned area. The drain pan must cover the entire area under the furnace (and air conditioning coil if applicable).

For installations above 7000 feet, please refer to the furnace Specification Sheets for required kit(s).

Contact the distributor for a tabular listing of appropriate manufacturer’ s kits for propane gas and/or high altitude installations. The indicated kits must be used to insure safe and proper furnace operation. All conversions must be performed by a qualified installer , or service agency .

This furnace is shipped from the factory configured for natural gas at standard altitude. Propane gas installations require an orifice and spring change to compensate for the energy content difference between natural and propane gas.

High altitude installations may require both a pressure switch and an orifice/spring change. These changes are necessary to compensate for the natural reduction in the density of both the gas fuel and the combustion air at higher altitude. For furnaces being converted to LP gas, it is strongly recommended that a LPLP03 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.

. THE

This manual will refer to the pipe that discharges products of combustion to the outdoors as the “vent” pipe or “flue” pipe. The pipe that supplies air for combustion to the furnace will be referred to as the “intake” pipe or “combustion air” pipe.

A condensing gas furnace achieves its high level of efficiency by extracting almost all of the heat from the products of combustion and cooling them to the point where condensation takes place. Because of the relatively low flue gas temperature and water condensation requirements, PVC or ABS are typically used as venting and intake pipe materials. In Canada, ABS is not an approved vent pipe material but it is permissible to use as combustion air pipe material.

In addition to PVC and ABS pipe and fittings, Innoflue® by Centrotherm Eco Systems and PolyP ro® by M&G Duravent are also approved vent and combustion air materials for installations in the U.S.A. and Canada. Manufacturers Installation instructions for these products must be followed. These products have specific instructions for installing, joining and terminating. Do not mix materials or components of one manufacturer with materials or components of another manufacturer.

All furnaces are manufactured with 2" vent / intake pipe and connectors. For furnaces requiring installation of 3" pipe,

the transition from 2" to 3" should be done as close to the furnace as practically possible.

This furnace must not be connected to T ype B, BW, or L vent or vent connector, and must not be vented into any portion of a factory built or masonry chimney except when used as a pathway for PVC as described later in this section. Never common vent this appliance with another appliance or use a vent which is used by a solid fuel appliance. Do not use commercially available “no hub connectors” other than those shipped with this product.

It is the responsibility of the installer to follow the manufacturers’ recommendations and to verify that all vent/flue piping and connectors are compatible with furnace flue products. Additionally , it is the responsibility of the installer to ensure that all piping and connections possess adequate structural integrity and support to prevent flue pipe separation, shifting, or sagging during furnace operation.

DUAL CERTIFICATION: NON-DIRECT/DIRECT VENT

This furnace is dual certified and may be installed as a non-direct vent (single pipe) or direct vent (dual pipe) appliance. A non-

direct vent installation requires only a vent/flue pipe, while a direct vent installation requires both a vent/flue pipe and a com-

bustion air intake pipe. Refer to the appropriate section for details concerning piping size, length, number of elbows, furnace connections, and terminations.

pipe must meet ASTM D1527 and, if used in Canada, must be CSA listed. Solvent cement for ABS to ABS joints must meet ASTM D2235 and, if used in Canada, must be CSA listed. The solvent cement for the PVC to ABS transition joint must meet ASTM D3138. Fittings must be DWV type fittings meeting ASTM D2661 and ASTM D3311 and, if used in Canada, must be CSA listed. Carefully follow the manufacturers’ instructions for cutting, cleaning, and solvent cementing PVC and/or ABS.

All 90° elbows must be medium radius (1/4 bend DWV) or long radius (Long sweep 1/4 bend DWV) types conforming to ASTM D3311. A medium radius (1/4 bend DWV) elbow measures 3 1/ 16” minimum from the plane of one opening to the center line of the other opening for 2” diameter pipe, and 4 9/16” minimum for 3” pipe.

PROPER VENT/FLUE AND COMBUSTION AIR PIPING PRACTICES

Adhere to these instructions to ensure safe and proper furnace performance. The length, diameter , and number of elbows of the vent/flue pipe and combustion air pipe (when applicable) affects the performance of the furnace and must be carefully sized. All piping must be installed in accordance with local codes and these instructions.

Some models require the use of 3” pipe. Do not transition from a 2” to 3” pipe in a horizontal section of pipe as this may create a water trap.

Piping must be adequately secured and supported to prohibit sagging, joint separation, and/or detachment from the furnace. Horizontal runs of vent/flue piping must be supported every three to five feet and must maintain a 1/4 inch per foot downward slope, back towards the furnace, to properly return condensate to the furnace’s drain system. Allowances should be made for minor expansion and contraction due to temperature variations. For this reason, particular care must be taken to secure piping when a long run is followed by a short offset of less than 40 inches.

Precautions should be taken to prevent condensate from freezing inside the vent/flue pipe and/or at the vent/flue pipe termination. All vent/flue piping exposed to freezing temperatures below 35°F for extended periods of time must be insulated with 1/2” thick closed cell foam. Also all vent/flue piping exposed outdoors in excess of the terminations shown in this manual (or in unheated areas) must be insulated with 1/2” thick closed cell foam. Inspect piping for leaks prior to installing insulation.

NOTE: In Canada, the current edition of CAN/CSA B149.1-15 takes precedence over the preceding termination description.

CANADIAN VENT PIPE & COMBUSTION AIR PIPE REQUIRE-

MENTS

All installations in Canada must conform to the requirements of CAN/CSA B149.1-15 code. All vent components,including primer and cement, must be listed to ULC S636. The certified pipe and fittings should be clearly marked with the ULC standard “S636”. The primer and cement used must be of the same manufacturer as the vent system. For Royal Pipe System 636; use GVS-65 Primer (Purple) and GVS-65 PVC Solvent Cement. For IPEX System 636, use PVC/CPVC Primer, Purple or clear . Use PVC Solvent Cement (Gray). For Canadian installations, ABS may be used as a combustion air pipe only . ABS is not an approved vent material in Canada. If ABS is used as a combustion air pipe, it must be CSA certified. Always follow the manufacturer ’ s instructions in the use of primer and cement. Do not use primer and cement around potential sources of ignition. Do not use primer or cement beyond its expiration date. The safe operation, as defined by ULC S636, of the vent system is based on following these installation instructions, the vent system manufacturer’ s installation instructions, and proper use of primer and cement. It is recommended under this standard, that the vent system be checked once a year by qualified

service personnel. All fire stops and roof flashings used with this system must be UL listed. Acceptability under CAN/CSA B149.1-15 is dependent upon full compliance with all installation instructions. Consult the authority having jurisdiction (gas inspection authority, municipal building department, fire department, etc.) before installation to determine the need to obtain a permit. *IPEX System 636™ is a trademark of IPEX Inc. Carefully follow the pipe manufacturers’ instructions for cutting, cleaning, and solvent cementing PVC and/or ABS. The vent can be run through an existing unused chimney provided the space between the vent pipe and the chimney is insulated and closed with a weather-tight, corrosion-resistant flashing.

STANDARD FURNACE CONNECTIONS

It is the responsibility of the installer to ensure that the piping connections to the furnace are secure, airtight, and adequately supported.

VENT/FLUE PIPE

The vent pipe outlet is sized to accept 2” pipe. Secure vent/ flue pipe directly into the furnace fitting with the appropriate glue. Alternately, a small section of 2" pipe may be glued in the furnace socket and a rubber coupling installed to allow removal for future service. Combustion Air and Vent piping should be routed in a manner to avoid contact with refrigerant lines, metering devices, condensate drain lines, etc. If necessary , clearances may be increased by creating an offset using two 45 degree elbows. This joint can be rotated on the fitting to establish maximum clearance between refrigerant lines, metering devices, and condensate drain lines, etc. This joint is the equivalent of one 90 deg. elbow when considering elbow count. (Figure 8A)

GLOVES AS A

On upflow units secure the combustion air intake pipe to the air intake coupling by using a take apart rubber coupling supplied with the furnace or a plastic coupling. Also, the intake coupling may be inverted to allow the intake pipe to be glued directly to it. After inverting the coupling, secure it to the furnace top with screws. On counterflow units secure the combustion air intake pipe to the air intake coupling using the rubber coupling and worm gear hose clamps provided with the unit. The counterflow rubber coupling allows service removal of air intake piping internal to the furnace blower compartment. The combustion air intake pipe can also be secured directly to the counterflow unit air intake pipe coupling.

COMBUSTION AIR INT AKE OPTIONS: The RF000142 coupling can be secured directly to the furnace intake coupling if condensation is a concern. If the RF000142 is used on the combustion air inlet, it must be installed with the arrow pointing up. It should be noted, the combustion air will actually be moving in a direction opposite of the arrow on the RF000142 coupling. It must have a field supplied, trapped drain tube free-draining to proper condensate disposal location. A loop in the drain tube can serve as a trap. The unused RF000142 drain fitting should be capped. (Figure 8B) A tee installed in the intake pipe is also an acceptable method of catching condensation. It must have a field supplied, trapped drain tube or pipe, free-draining to proper condensate disposal location. A loop in the drain tube can serve as a trap.

NON-DIRECT VENT (SINGLE PIPE) PIPING

Non-direct vent installations require only a vent/flue pipe. The vent pipe can be run horizontally with an exit through the side of the building or run vertically with an exit through the roof of the building. The vent can also be run through an existing unused chimney; however , it must extend a minimum of 12 inches above the top of the chimney . The space between the vent pipe and the chimney must be closed with a weather-tight, corrosion-resistant flashing.

Although non-direct vent installations do not require a combus- tion air intake pipe, a minimum of one 90° elbow should be attached to the furnace’s combustion air intake if: an upright installation uses the standard intake location, or a horizontal installation uses the alternate air intake location. This elbow will guard against inadvertent blockage of the air intake.

NOTE: If either a 90 degree or 45 degree elbow is used for termination, it must be pointed downward.

The vent/flue pipe may terminate vertically , as through a roof, or horizontally , as through an outside wall.

Vertical vent/flue pipe terminations should be as shown in the following figure. Refer to Vent/Flue Pipe and Combustion Air Pipe - T ermination Locations for details concerning location restrictions. The penetration of the vent through the roof must be sealed tight with proper flashing such as is used with a plastic plumbing vent.

Horizontal vent/flue pipe terminations should be as shown in the following figure. Refer to Vent/Flue Pipe and Combustion Air Pipe. To secure the pipe passing through the wall and prohibit damage to piping connections, a coupling should be installed on either side of the wall and solvent cemented to a length of pipe connecting the two couplings. The length of pipe should be the wall thickness plus the depth of the socket fittings to be installed on the inside and outside of the wall. The wall penetration should be sealed with silicone caulking material.

NOTE: Terminate both pipes in the same pressure zone (same side of roof, no major obstacles between pipes, etc.).

DIRECT VENT (DUAL PIPE) PIPING

Direct vent installations require both a combustion air intake and a vent/flue pipe. The pipes may be run horizontally and exit through the side of the building or run vertically and exit through the roof of the building. The pipes may be run through an existing unused chimney; however, they must extend a minimum of 12 inches above the top of the chimney . The space between the pipes and the chimney must be closed with a weather tight, corrosion resistant flashing. Both the combustion air intake and a vent/flue pipe terminations must be in the same atmospheric pressure zone. Refer to Vent/Flue and Combustion Air Pipe - T ermination Locations or Concentric Vent Termination for spe- cific details on termination construction. For details concerning connection of pipes to the furnace, refer to the Vent/Flue Pipe

and Combustion Pipe - Standard Furnace Connections or Alter - nate Furnace Connections.

GENERAL DRAIN INFORMATION

All furnace models come with a factory installed drain trap. For vertical installations, the trap will remain in the factory position. All furnace models installed horizontally require the trap to be relocated. Many drain hoses have a built–in grommet which will provide a cabinet seal when installed. See instructions below for your model and installation position. NOTE: Both sides of the drain trap must be primed

prior to initial furnace start up

ONDENSA TE DRAIN LINES

A condensing gas furnace achieves its high level of efficiency by extracting heat from the products of combustion to the point where condensation takes place. The condensate must be collected in the furnace drain trap and routed to an appropriate drain location in compliance with local and national codes.

Follow the bullets listed below when installing the drain system. Refer to the following sections for specific details concerning furnace drain trap installation and drain hose hook ups.

• The drain trap supplied with the furnace must be used.

• The drain trap must be primed at time of installation.

• The drain line between furnace and drain location must meet local and national codes.

• The drain line between furnace and drain location must maintain a 1/4 inch per foot downward slope toward the drain.

• Do not trap the drain line in any other location than at the drain trap supplied with the furnace.

• If the drain line is routed through an area which may see temperatures near or below freezing, precautions must be taken to prevent condensate from freezing within the drain line.

& D

RAIN TRAP

Drain the furnace and air conditioning coil if applicable, in compliance with code requirements. In horizontal installations, a field installed rubber coupling will allow the drain trap to be removed for cleaning. The drain trap must be primed before initial furnace start up. When an air conditioning coil drain is connected to the field supplied furnace drain, it must be vented with an open tee installed at a height no higher than the bottom of the furnace collector box to prevent air conditioning condensate from backing up into the furnace if the common drain became blocked.

UPFLOW MODEL INSTALLED VERTICALLY

The trap and factory installed hoses remain as shipped. The furnace drain may exit either the right or left side of the furnace cabinet. Both sides of the cabinet have two .875” diameter holes which can be used interchangeably for drain and low voltage wiring purposes. If a higher drain exit is needed, a .875” diameter hole may be added in the area

shown in Figure 21. Any unused cabinet opening must be sealed. Do not allow drain hose to sag or trap water.

NOTE: Hoses are model specific

and not all hoses will be shipped with all models.

A single-stage thermostat with only one heating stage may be used to control this furnace. The application of a singlestage thermostat offers a timed transition from low to high fire. The furnace will run on low stage for a fixed period of time before stepping up to high stage to satisfy the thermostat’ s call for heat. The delay period prior to stepping up can be set at either a fixed 10 or 20 minute time delay or a load based variable time between 1 and 12 minutes (AUTO mode). If the AUT O mode is selected, the control averages the cycle times of the previous three cycles and uses the average to determine the time to transition from low stage to high stage.

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 with three stages of heat is required to properly use a two-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.

TWINNING

Using the “TWIN” terminals and proper wiring enables two *MEC96 furnaces of the same model and size to be twinned. T winning 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 external kits or parts.

· The staging DIP switches and speed tap DIP switches must be set the same on both furnaces.

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 V AC service panel phase leg). T o verify that the furnaces are in phase, check from L1 to L1 on each furnace with a voltmeter. If the furnaces are in phase, the voltage between both furnaces will be ZERO.

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.

Inlet gas supply pressures must be maintained within the ranges specified in the adjacent 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.

CAUTION

PREVENT UNRELIABLE OPERATION OR EQUIPM EN T DAMAGE, THE INLET GAS SUPPLY PRESSURE MUST BE AS SPECIFIED ON THE UNIT RATING PLATE WITH ALL OTHER HOUSEHOLD GAS FIRED APPLIANCES OPERATING

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.

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, NFP A 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.

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

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 National Fuel Gas Code, NFPA 54/ANSI Z223.1.

T o connect the furnace to the building’ s gas piping, the installer must supply a ground joint union, drip leg, manual shutoff valve, and line and fittings to connect to gas valve. In some cases, the installer may also need to supply a transition piece from 1/2" pipe to a larger pipe size.

The following stipulations apply when connecting gas piping. Refer to Gas Piping Connections figure for typical gas line connections to the furnace.

• 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 building piping.

Where possible, use new pipe that is properly chamfered,

reamed, and free of burrs and chips. If old pipe is used, be sure it is clean and free of rust, scale, burrs, chips, and old pipe joint compound.

• Use pipe joint compound on male threads ONL Y. Always

use pipe joint compound (pipe dope) that is APPROVED FOR ALL GASSES. DO NOT apply compound to the first two threads.

• 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.

• Install a 1/8" NPT pipe plug fitting, accessible for test

gage connection, immediately upstream of the gas supply connection to the furnace.

• Always use a back-up wrench when making the 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. Maximum torque for the gas valve connection is 375 in-lbs; excessive over-tightening may damage the gas valve.

• 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. In order to seal the grommet cabinet penetration, rigid pipe must be used to reach the outside of the cabinet. A semi-rigid connector to the gas piping may be used from there.

• Use listed gas appliance connectors in accordance with

their instructions. Connectors must be fully in the same room as the furnace.

• Protect connectors and semirigid tubing against physical

and thermal damage when installed. Ensure aluminumalloy tubing and connectors are coated to protect against external corrosion when in contact with masonry , plaster , or insulation, or subjected to repeated wetting by liquids such as water (except rain water), detergents, or sewage.

AVOID THE POSSIBILITY OF EXPLOSION OR FIRE, NEVER USE A MATCH

OR OPEN FLAME TO TEST FOR LEAKS

GAS PIPING CHECKS

Before placing unit in operation, leak test the unit and gas connections.

Check for leaks using an approved chloride-free soap and water solution, an electronic combustible gas detector, or other approved testing methods.

NOTE: Never exceed specified pressures for testing. Higher pressure may damage the gas valve and cause subsequent overfiring, resulting in heat exchanger 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 1/2 psig (3.48 kPa).

Isolate this unit from the gas supply piping system by closing its external manual gas shutoff valve before pressure testing supply piping system with test pressures equal to or less than 1/2 psig (3.48 kPA).

The gas piping may enter the left or right side of the furnace cabinet. The installer must supply rigid pipe long enough to reach the outside of the cabinet to seal the grommet cabinet penetration. A semi-rigid connector to the gas piping can be used outside the cabinet per local codes. 1/2” NPT pipe and fittings are required. For models with an “L” shaped manifold, a 4 1/2” long nipple is required. For models with a hook shaped manifold, a 2” long nipple is required.

A semi-rigid connector to the gas piping can be used outside the cabinet per local codes. From the elbow, the length of pipe and the fittings required will vary by the side chosen,

DUCT WORK - AIR FLOW

Duct systems and register sizes must be properly designed for the CFM and external static pressure rating of the furnace. Design the ductwork in accordance with the recommended methods of “Air Conditioning Contractors of America” Manual D.

Install the duct system in accordance with Standards of the National Board of Fire Underwriters for the Installation of Air Conditioning, Warm Air Heating and Ventilating Systems. Pamphlets No. 90A and 90B.

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 listed in the Safety Considerations section 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 ” WC at the furnace manifold with all gas appliances in operation. Maintaining proper gas pressure depends on three main factors:

1. V aporization 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.

Complete information regarding tank sizing for vaporization, recommended regulator settings, and pipe sizing is available from most regulator manufacturers and propane gas suppliers.

Since propane gas will quickly dissolve white lead and most standard commercial compounds, special pipe dope must be used. Always use a pipe thread sealant approved for all gases.

Refer to the this illustration for typical propane gas installations and piping.

A closed return duct system must be used, with the return duct connected to the furnace. NOTE: Ductwork must never be at- tached to the back of the furnace. For upflow installations requiring 1800 CFM or more, use either two side returns or bottom return or a combination of side /bottom. Flexible joints may be used for supply and return connections to reduce noise transmission. T o 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. Never use a room, closet, or alcove as a return air chamber .

CHECKING DUCT STATIC

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

WARNING

EVER ALLOW THE PRODUCTS OF COMBUSTION, INCLUDING CARB ON MONOXIDE, TO ENTER THE RETU RN DUCT WORK OR CIRCULATION AIR SUPPLY

T otal external static refers to everything 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.

Second Sta g e Regulator

T o determine total external duct static pressure, proceed as follows;

1. With clean filters in the furnace, use a draft gauge (inclined manometer) to measure the static pressure of the return duct at the inlet of the furnace. (Negative Pressure)

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 theses components, as shown in the following drawing.

4. Consult proper tables for the quantity of air .

2. Measure the static pressure of the supply duct. (Positive Pressure)

3. The difference between the two numbers is .4” w .c.

Example: static reading from return duct = -.1" w .c. static reading from supply duct = .3" w .c. total external static pressure on this system = .4" w .c.

BOTTOM RETURN AIR OPENING [UPFLOW MODELS]

The bottom return air opening on upflow models utilizes a “lance and cut” method to remove sheet metal from the duct opening in the base pan. T o remove, simply press out the lanced sections by hand to expose the metal strips retaining the sheet metal over the duct opening. Using tin snips, cut the metal strips and remove the sheet metal covering the duct opening. In the corners of the opening, cut the sheet metal along the scribe lines to free the duct flanges. Using the scribe line along the duct flange as a guide, unfold the duct flanges around the perimeter of the opening using a pair of seamer pliers or seamer tongs.

NOTE: Airflow area will be reduced by approximately 18% if duct flanges are not unfolded. This could cause performance issues and noise issues.

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 airstream. The access panel must be made to prevent air leaks when the furnace is in operation.

When the furnace is heating, the temperature of the return air entering the furnace must be between 55°F and 100°F.

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). As an alternative a media air filter or electronic air cleaner can be used as the requested filter . Consider installing an air cleaner with deep-pleated media filter at the time of furnace installation. A deep-pleated filter with a MERV rating of 8 (minimum) will often provide better filtration to protect equipment and the air distribution system than a standard 1" filter and often has lower static pressure loss than a 1" filter . Also a deep-pleated filter will typically require less frequent replacement intervals. Avoid using highly restrictive 1" filters which produce static pressure loss greater than .25" W.C. In some installations the minimum filter size required will not lend itself to a filter installation on the side of the furnace. The installation of a centrally installed air cleaner cabinet or a return duct filter installation may offer more practicality .

Clean Comfort™ brand MERV 11 air cleaners have 5¼” media filters and are available in the following configurations. Consult your distributor for information on our complete line of IAQ Clean Comfort™ products.

The figure below shows possible filter locations.

GAS INPUT RATE MEASUREMENT (NATURAL GAS ONLY)

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.

The actual gas input rate to the furnace must never be greater than that specified on the unit rating plate. T o measure natural gas input using the gas meter , use the following procedure.

1. T urn OFF the gas supply to all other gas-burning appliances except the furnace.

2. While the furnace is operating a t high fire rate, time and record one complete revolution of the gas meter dial measuring the smallest quantity , usually the dial that indicates 1/2 cu. ft. per revolution. You will use this number to calculate the quantity of gas in cubic ft. if the furnace would consume if it ran steadily for one hour (3600 seconds).

3. If the 1/2 cu. ft. dial was used, multiply your number x 2.

T emperature rise must be within the range specified on the unit rating plate. An incorrect temperature rise may result in condensing in or overheating of the heat exchanger . An airflow and temperature rise table is provided in the Specification Sheet applicable to your model. Determine and adjust temperature rise as follows:

1. Operate furnace with burners firing for approximately ten minutes. Ensure all registers are open and all duct dampers are in their final (fully or partially open) position.

2. Place thermometers in the return and supply ducts as close to the furnace as possible. Thermometers must not be influenced by radiant heat by being able to “see” the heat exchanger.

3. Subtract the return air temperature from the supply air temperature to determine the air temperature rise. Allow adequate time for thermometer readings to stabilize.

4. Adjust temperature rise by adjusting the circulator blower speed. Increase blower speed to reduce temperature rise. Decrease blower speed to increase temperature rise. Refer to Startup Procedure and Adjustment -Circulator Blower Speeds for speed changing details.

SUPPLY AIR

EXAMPLE: If it took 23 seconds to complete one revolution of the 1/2 ft. dial (23 x 2 = 46).

This tells us that at this rate, it would take 46 seconds to consume one cu. ft. of gas. 3600 / 46 = 78.

This tells us that in one hour , the furnace would consume 78 cu. ft. of gas.

The typical value range for 1 cu. ft. of natural gas is around 1000 BTU. Check with your gas utility, if possible. In this example, the furnace is consuming 78,000 BTUH.

NOTE: The final manifold pressure cannot vary by more than ± 0.3” w .c. for Natural and + 0.5” for LP from

CIRCULATOR BLOWER SPEEDS

This furnace is equipped with a multi-speed ECM motor . The line voltage (115 V AC) power supply to the motor is constant

and not switched by the control board. Motor operation is also dependent on a pulsing D.C. signal on one of the four speed taps on the motor . The airflow tables for heating and cooling speeds show the relationship between airflow (CFM) and external static pressure for each size furnace.

WARNING

AVOID PERSONAL INJURY OR DEATH DUE TO ELECTRICAL SHOCK

TURN

OFF

POWER TO THE FURNACE BEFORE CHANGING SPEED TAPS

Circulator Blower Speed Facts

1. Motor speed T ap wiring must remain in factory position on the control board and motor .

2. There are 4 speed T ap wires to the motor T1, T2, T3, T4.

3. There are 5 speeds available, depending on DIP switch settings and found in air flow table for each size furnace.

4. Heating input (W1/ W2) always has priority over all other thermostat input.

5. Cooling input (YLo/ Y) has priority over continuous fan input.

6. Continuous fan input (G) has lowest priority.

1. Refer to the air flow table for your specific model

furnace

2. If a cooling or heat pump condensing unit is being

used in conjunction with this furnace, DIP switches S1-1, S1-2, S1-3 are used to select the proper cooling speeds to match the outdoor unit size. Typical CFM requirements are 400 CFM / Ton.

3. Heating speeds are selected DIP switches

S1-4 & S2-1

1. T urn OFF power to the furnace.

2. Select the cooling blower speeds that match the installation requirements from the airflow table in this manual or the Service Manual, If factory cooling speeds do not match the installation requirements, the dip switch settings must be changed from factory position

3. T urn ON power to furnace.

4. Verify proper temperature rise in heat mode and CFM in cooling mode

BLOWER HEAT OFF DELAY TIMINGS

The integrated control module provides a selectable heat off delay function. The heat off delay period may be set to 90, 120, 150, 180 seconds using the DIP switches provided on the control module. The delay is factory shipped at 150 seconds but may be changed to suit the installation requirements and/or homeowner preference.

• When power is supplied, the control will energize the Red LED, microcomputer runs its self-check

routine.

• The control will check the status of the gas valve circuitry.

• Line polarity is checked.

• The control then enters standby waiting for a call for heat or cool.

• The Furnace status LED will display a slow green flash signaling standby mode.

HEATING MODE

Call for 1st Stage Heat Only:

• On a call for first stage heat, the thermostat contacts close signaling the control module.

• The microcomputer runs its self-check routine.

• The Amber LED will display a slow flash signaling normal heat operation.

• The control module checks the high limit (and/or auxiliary limit) switch(es) for normally closed contacts.

• The control checks the low pressure switch for a shorted condition

• The gas valve relay status is checked for proper operation. Once the low pressure switch is detected open, the inducer blower is energized at high speed and the humidifier is enabled.

• The low pressure switch is checked for closure.

• Once the low pressure switch is closed, the prepurge period begins. The inducer will be energized at high speed for the pre-purge period.

• Following the completion of pre-purge, the inducer switches to low speed and the igniter warm up period begins.

• After completion of the igniter warm up period: a. Trial for ignition begins. b. The first stage of the gas valve is energized.

• The igniter is de-energized when flame is sensed or at the conclusion of the ignition activation period

(IAP), whichever comes first.

• When flame is sensed, the delay to heat on period begins timing.

• After the delay to heat on period, the circulator fan is energized at the low heat speed.

• The EAC contact is energized with the circulator .

Call for 2nd Stage After First Stage:

• The inducer motor goes to high speed.

• The pressure switches are checked for closure. Closure of the second stage pressure switch will

energize the high fire stage of the gas valve.

• The high speed circulator output is energized. NOTE: A call for 2

will be ignored, and a three amber flash code will be displayed on the LED. This error code will only be stored in memory once during a single power cycle.

2nd Stage Satisfied, First Stage Still Calling:

• When the second stage of the thermostat is satisfied, the inducer blower is reduced to low speed which de-energizes the second stage of the gas valve.

• After the high heat off delay expires, the circulator is reduced to low heat speed.

• Note: A call for second stage without a call for first stage will be ignored.

AFETY CIRCUIT DESCRIPTION

A number of safety circuits are employed to ensure safe and proper furnace operation. These circuits serve to control any potential safety hazards and serve as inputs in the monitoring and diagnosis of abnormal function. These circuits are continuously monitored during furnace operation by the integrated control module.

INTEGRATED CONTROL MODULE

The integrated control module is an electronic device which, if a potential safety concern is detected, will take the necessary precautions and provide diagnostic information through an LED.

PRIMARY LIMIT

The primary limit control is located on the partition panel and monitors heat exchanger compartment temperatures. It is a normally-closed (electrically), automatic reset, temperature-activated sensor . The limit guards against overheating as a result of insufficient conditioned air passing over the heat exchanger .

AUXILIARY LIMIT

The auxiliary limit controls are located on or near the circulator blower and monitors blower compartment temperatures. They are a normally-closed (electrically), manual-reset sensors. These limits guard against overheating as a result of insufficient conditioned air passing over the heat exchanger.

ROLLOUT LIMIT

The rollout limit controls are mounted on the burner/manifold assembly and monitor the burner flame. They are normallyclosed (electrically), manual-reset sensors. These limits guard against burner flames not being properly drawn into the heat exchanger.

PRESSURE SWITCHES

The pressure switches are normally-open (closed during operation) negative air pressure-activated switches. They monitor the airflow (combustion air and flue products) through the heat exchanger via pressure taps located on the induced draft blower and the coil front cover. These switches guard against insufficient airflow (combustion air and flue products) through the heat exchanger and/or blocked condensate drain conditions.

FLAME SENSOR

objects, etc.). If you come in contact with an ungrounded object, repeat step 2 before touching control or wires.

CHECKING FLAME SIGNAL

Flame current can be measured in two ways:

1. Putting a D.C. microamp meter in series with the flame rod

2. Putting a D.C. volt meter across the two solder pads in the flame current section of the control board.

1 D.C. volt = 1 microamp. See Figure 41.

Flame Current

Solder Pads

The flame sensor is a probe mounted to the burner/manifold assembly which uses the principle of flame rectification to determine the presence or absence of flame.

ROUBLESHOOTING

ELECTROSTATIC DISCHARGE (ESD) PRECAUTIONS

NOTE: Discharge body’ s static electricity before touching unit.

An electrostatic discharge can adversely affect electrical components.

1. Disconnect all power to the furnace. Do not touch the integrated control module or any wire connected to the control prior to discharging your body’s electrostatic charge to ground.

2. Firmly touch a clean, unpainted, metal surface of the furnace away from the control. Any tools held in a person’ s hand during grounding will be discharged.

Figure 41

LIMIT FAULT CODES

If the control detects the high limit circuit open, the RED LED will flash FOUR times and energize the inducer and indoor blower .

If the limit circuit opens five times within a single call for heat, the furnace will go into lockout for one hour . The RED LED will display a FOUR flash code during this time. The control board can be reset by cycling 115 volt power to the furnace.

If the limit circuit opens and does not close within five minutes, the control assumes the blower has failed the RED LED will flash ELEVEN times.

If the limit circuit opens and does not close within fifteen minutes, the control assumes the manual rollout or fuse has opened and the RED LED will flash FIVE times. The control will enter a one hour lockout and the inducer will run continuously.

In an open limit condition the red LED will flash as described above but the error code will not be stored in memory until the limit resets or until 15 minutes has elapsed. So if the limit resets in less than 5 minutes a four flash code will be stored. If the limit resets in more than 5 but less than 15 minutes, an eleven flash code will be stored. If the limit is still open after 15 minutes, a five flash code will be stored.

DIAGNOSTIC CHART

Refer to the Troubleshooting Chart in the back of this manual for assistance in determining the source of unit operational problems.

External Lockout

- A control lockout resulting from an external fault sensed by the control, such as an unsuccessful recycle or retry period, or a limit trip. Once in External Lockout, the control will shut down for a period of one hour before attempting another trial for ignition.

Internal Lockout

- A failure internal to the control board.

FAULT RECALL

Retrieving Fault Codes

T o retrieve fault codes, push and release the “LAST ERROR” button for more than 1/5 second and less than 5 seconds (the LED will indicate this period by solid GREEN for 1/5 second to 5 seconds). The LED will flash up to five stored fault codes, beginning with the most recent. If there are no fault codes in memory , the LED will flash two green flashes. The control will flash the most recent error first and the oldest error last. If multiple faults exist there will be 2 seconds between codes. Solid LED error codes will not be displayed.

Fault Code Reset

To clear the fault code memory, push and hold the “LAST ERROR” button for more than 5 seconds and less than 10 seconds (the LED will indicate this period by RAPID GREEN FLASH for 5 seconds to 10 seconds). The LED will flash three green flashes when the memory has been cleared.

The ignition control is equipped with a momentary push button switch that can be used to display on the diagnostic LED the last five faults detected by the control. The control must be in Standby Mode (no thermostat inputs) to use the feature. Depress the push button switch for approximately 2

seconds. Release the switch when the LED is turned off. The diagnostic LED will then display the flash codes associated with the last five detected faults. The order of display is the most recent fault to the least recent fault.

RESETTING FROM LOCKOUT

Furnace lockout results when a furnace is unable to achieve ignition after three attempts during a single call for heat. It is characterized by a non-functioning furnace and a one flash diagnostic LED code. If the furnace is in “lockout”, it can be reset in any of the following ways.

1. Automatic reset. The integrated control module will automatically reset itself and attempt to resume normal operations following a one hour lockout period.

2. Manual power interruption. Interrupt 115 volt power to the furnace for 1 - 20 seconds.

3. Manual thermostat cycle. Lower the thermostat so that there is no longer a call for heat then reset to previous setting. Interrupt thermostat signal to the furnace for 1 - 20 seconds.

NOTE: If the condition which originally caused the lockout still exists, the control will return to lockout. Refer to the T roubleshooting Chart for aid in determining the cause.

NLY A QUALIFIED SERVICER SHOULD EVER

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.

FLUE PASSAGES (QUALIFIED SERVICER ONLY)

The heat exchanger flue passageways should be inspected at the beginning of each heating season.
