GENERAL INFORMATION

The RGPE/RGLE series furnaces are design certified by CSA for use with natural and propane gasesas follows:

As a CategoryI furnace, it may be vented vertically with type B-1 vent pipe and alsomay be common vented as described in these instructions.

This furnace should be installed in accordancewith the American National Standard Z223.1 - latest edition booklet entitled “National Fuel Gas Code” (NFPA

54) (in Canada, CSAB149.1 and .2 Installation Codes for gas burning appliances), and the requirements or codes of the localutility or other authorityhaving jurisdiction including local plumbing or wastewater codes.

The NationalAppliance Energy ConservationAct (NAECA) of 1987 states that any gas furnace manufacturedafter January 1, 1992, must have a minimumAnnual Fuel Utilization Efficiency (AFUE) of 78%.The higher the AFUE percentage the more usableheat energy the consumer gets for every dollar of fuel purchased.This is similarto the EPA's minimum gas mileage requirement for automobiles. It gives the consumera relativelyeasy way to make direct efficiency comparisons between differentfurnace brands and styles.

A high AFUE value, which translates into a low operating cost, is not the only concern thatconsumers have. Theyalso want a furnace with a reasonable installed cost. They want a furnace that provides them with comfort – their main concern.And they expecta furnace with exceptional reliability and longevity.

Gas furnace manufacturers are always striving to provide consumers with the best furnace value. The Low Profile Furnace addresses all those consumer needs. It gives exceptionalefficiency with a low installationcost. It delivers the comfort the customer wants along with the reliability they expect.

The key to all these customer benefits is the furnace's heat exchanger.The materialsused to construct the furnace in general and the heatexchanger in particular make it a rugged,long lasting unit. The unique heat exchanger design provides the customer with a furnace only 34 inches high.This gives the consumer a unit easily installed in almost every location that accepts all customary accessories.

With the introduction of higherefficiency furnaces, special attention mustbe paid to the venting system.Only listed venting systems may be used as stated in the installation instructions and the National

Fuel Gas Code, ANSI Z223.1 (NFPA 54), or the Canadian CAN/CGA B149.1 and B149.2 InstallationCodes for Gas Burning Appliances.Sincefurnace tech-

nology and ventingrequirements are changing, awarenessof local, state, and federal codes and industry changes is imperative.

NOTE: Always perform a proper heat loss calculation beforespecifying the furnace size. This ensures that the furnace is sized to adequately, economically, heat the building and provide the correct airflow for yourapplication.

IMPORTANT:PROPERAPPLICATION, INSTALLATION AND MAINTENANCE OF THIS FURNACE ISA MUST IF CONSUMERSARE TO RECEIVE THE FULLBENEFITS FOR WHICH THEY HAVE PAID.

IMPORTANT INFORMATION ABOUT EFFICIENCY AND INDOOR AIR QUALITY

Central cooling and heating equipment is only as efficient as the duct system that carries the cooled or heated air. To maintain efficiency, comfort and good indoor air quality, it is important to have the proper balance between the air being supplied to each room and the air returning to the cooling and heating equipment.

FIGURE 1

MIGRATION OF DANGEROUS SUBSTANCES, FUMES, AND ODORS INTO LIVING SPACES

Proper balance and sealing of the duct system improves the efficiency of the heating and air conditioning system and improves the indoor air quality of the home by reducing the amount of airborne pollutants that enter homes from spaces where the ductwork and / or equipment is located. The manufacturer and the U.S. Environmental Protection Agency’s Energy Star Program recommend that central duct systems be checked by a qualified contractor for proper balance and sealing.

WARNING

DUCT LEAKS CAN CREATE AN UNBALANCED SYSTEM AND DRAW POLLUTANTS SUCH AS DIRT, DUST,FUMES AND ODORS INTOTHE HOME CAUSING PROPERTY DAMAGE. FUMES AND ODORS FROM TOXIC,VOLATILE OR FLAMMABLE CHEMICALS, AS WELL AS AUTOMOBILE EXHAUST AND CARBON MONOXIDE (CO), CAN BE DRAWN INTO THE LIVING SPACETHROUGH LEAKING DUCTS AND UNBALANCED DUCT SYSTEMS CAUSING PERSONAL INJURY OR DEATH (SEE FIGURE 1).

• IF AIR-MOVING EQUIPMENT OR DUCTWORK IS LOCATED IN GARAGES OR OFF-GARAGE STORAGE AREAS - ALL JOINTS, SEAMS, AND OPENINGS IN THE EQUIPMENT AND DUCT MUST BE SEALED TO LIMIT THE MIGRATION OF TOXIC FUMES AND ODORS INCLUDING CARBON MONOXIDE FROM MIGRATING INTO THE LIVING SPACE.

• IF AIR-MOVING EQUIPMENT OR DUCTWORK IS LOCATED IN SPACES CONTAINING FUEL BURNING APPLIANCES SUCH

AS WATER HEATERS OR BOILERS

- ALL JOINTS, SEAMS, AND OPENINGS IN THE EQUIPMENT AND DUCT MUST ALSO BE SEALED TO PREVENT DEPRESSURIZATION OF THE SPACE AND POSSIBLE MIGRATION OF COMBUSTION BYPRODUCTS INCLUDING CARBON MONOXIDE INTOTHE LIVING SPACE.

NOTICE

WARNING

THIS FURNACE AND ANY OTHER FUEL-BURNING APPLIANCE MUST BE PROVIDED WITH ENOUGH FRESH AIR FOR PROPER COMBUSTION AND VENTILATION OF THE FLUE GASES. MOST HOMES WILL REQUIRETHAT OUTSIDE AIR BE SUPPLIED INTO THE FURNACE AREA. FAILURETO DO SO CAN CAUSE DEATH FROM CARBON MONOXIDE POISONING.

Adequate facilities for providing air for combustion and ventilation must be provided in accordance with section

5.3, Air for Combustion and Ventilation, of the National Fuel Gas Code, ANSI, Z223.1 latest edition or CSA B149.1 and .2 or, applicable provisions for the local building codes, and not obstructed so as to prevent the flow of air to the furnace.

COMBUSTION AIR REQUIREMENTS

IMPORTANT: Air for combustion and ventilation must not come from a corrosive atmosphere. Any failure due to corrosive elements in the atmosphere is excluded from warranty coverage.

The following types of installation may require OUTDOOR AIR for combustion, due to chemical exposures:

FIGURE 7

AIR FROM HEATED SPACE

Combustion air must be free of acid forming chemicals; such as sulphur, fluorine and chlorine. These elements are found in aerosol sprays, detergents, bleaches, cleaning solvents, air fresheners, paint and varnish removers, refrigerants and many other commercial and household products. Vapors from these products when burned in a gas flame form acid compounds. The acid compounds increase the dew point temperature of the flue products and are highly corrosive after they condense.

WARNING

ALL FURNACE INSTALLATIONS MUST COMPLYWITH THE NATIONAL FUEL GAS CODE AND LOCAL CODES TO PROVIDE ADEQUATE COMBUSTION AND VENTILATION AIR FOR THE FURNACE. FAILURE TO DO SO CAN CREATE HAZARDOUS CONDITIONS RESULTING IN PROPERTY DAMAGE, BODILY INJURY OR DEATH FROM SMOKE, FIRE OR CARBON MONOXIDE.

Combustion air requirements are determined by whether the furnace is in an open (unconfined) area or in a confined space such as a closet or small room. See Figures 7 and 8.

EXAMPLE 1. FURNACE LOCATED IN AN UNCONFINED SPACE

Using indoor air for combustion.

An unconfined space must have at least 50 cubic feet for each 1,000 BTUH of the total input for all appli ances

in the space. Here are a few

examples of the room sizes required for different inputs. The sizes are based on 8 foot ceilings.

BTUH Minimum Sq. Feet Typical Room Size

Input With 8' Ceiling With 8' Ceiling

50,000 312 14*x24* or 18*x18*

75,000 469 15*x31* or 20*x24* 100,000 625 20*x31* or 25*x25* 125,000 833 23*x34* or 26*x30*

If the open space containing the furnace is in a building with tight construction (contemporary construction), outside air may still be required for the furnace to operate and vent properly. Outside air openings should be sized the same as for a confined space.

FIGURE 8

EXAMPLE 2. FURNACE LOCATED IN A CONFINED SPACE

A confined space (any space smaller than shown above as “unconfined”) must have openings into the space which are located in accordance with the requirements set forth in the following subsections A and B. Size the openings by how they are connected to the heated area or to the outside, and by the input of all appliances in the space.

If confined space is within a building with tight construction, combustion air must be taken from outdoors or area freely communicating with the outdoors.

A. USING INDOOR AIR FOR COM-

BUSTION, ALL OF THE MODELS

IMPORTANT: Air should not be taken from a heated space with a fireplace, exhaust fan or other device that may produce a negative pressure.

If combustion air is taken from the heat-

ed area, the openings must each have at least 100 square inches of free area. Each opening must have at least one square inch of free area for each 1,000 Btuh of total input in the space. Here are some examples of typical openings required.

FURNACE CATEGORY INFORMATION

This furnace is shipped as a Category I type induced draft furnace. A Category I furnace operates with a nonpositive vent pressure and has a vent gas temperature at least 140°F above the dew point of the vent gases. A Category I type may be a draft hood equipped furnace or have a fan assisted combustion system (induced draft). The inducer is used to pull flue products through the combustion chamber and as they leave the furnace, most of the energy has been dissipated. The buoyant effect of the flue gases provides venting to the outdoors.

During the off cycle, the inducer is off and there is very little flow through the vent, cooling the vent. During the on cycle there is no dilution airflow, as with a draft hood type furnace. Although the vent heats up rapidly without dilution air, the flue products contain more water vapor, which results in a higher dew point temperature. It is most important that you follow the guidelines in these instructions to prevent the possible formation of condensation in the venting system.

As a Category I furnace it may be vented vertically with type B-1 vent pipe and also may be common vented, as described in these instructions.

A0991-01

IMPORTANT APPLICTION NOTES

When the furnace is used as a replacement, the existing vent system should be inspected to assure that there are no obstructions, blockage, or any signs of corrosion and is properly sized for use with this furnace.

NOTE: When the vent table permits more than one diameter of pipe for a connector or vent, the smallest permitted diameter must be used.

Vent pipe may be type “B-1,” either rigid or suitable flexible construction that carries a u.l. listing.

Common venting is allowed with vertical B-1 vent systems, and lined masonry chimneys. Follow the National Fuel Gas Code, ANSI Z223.1 and/or the Natural Gas Installation Code, CSA-B149.1 & .2 for proper installation practices.

NOTE: Follow combustion air instructions as outlined in this manual.

Single wall vent connectors to “B-1 vent or masonry chimneys” may be used under the guidelines of the National Fuel Gas Code, ANSI Z223.1 and/or the Natural Gas Installation Code, CSA-B149.1 & .2.

The entire length of the vent connector shall be readily accessible for inspection, cleaning and replacement.

“B-1” VERTICAL VENTING

Type “B-1” vents must be installed in accordance with the terms of their listings and the vent manufacturer’s instructions.

“B-1” vents must be supported and spaced in accordance with their listings and the manufacturer’s instructions. All vents must be supported to maintain their minimum clearances from combustible material.

*NOTE: All furnaces have a 3” vent connection as shipped from the factory. A 3” to 4” or 3” to 5” vent transition is required on all but the 50,000 BTUH models when vertically vented or common vented with metal vent pipes. THE VENT TRANSITION CONNEC-

TION MUST BE MADE ATTHE FURNACE VENT EXIT. It must originate with an adapter

if required, at the furnace flue collar and terminate either in a listed cap or roof assembly. When common venting, the vent connector size may differ from the above diameters depending on application. See ANSI Z21.47-1993/CSA-2.3-M93 or latest edition tables.

VERTICAL VENT SYSTEMS:

1. A gas vent shall terminate above the roof surface with a listed cap or listed roof assembly. Gas vents 12 inches in size or smaller with listed caps shall be permitted to be terminated in accordance with Figure 13, provided they are at least 8 feet from a vertical wall or similar obstruction. All other gas vents shall terminate not less than 2 feet above the highest point where they pass through the roof and at least 2 feet higher than any portion of a building within 10 feet.

2. A type B-1 gas vent shall terminate at least 5 feet in vertical height above the highest connected equipment draft hood or flue collar.

3. Must rise

/4” per foot away from the furnace on horizontal runs and be supported with straps or hangers so it has no sags or dips. Supports at 4 foot intervals and at all elbows are recommended.

4. The vent connector must be mechanically fastened to the outlet collar of the furnace with at least (2) sheet metal screws except vent connectors that are B-1 material. These shall be assembled in accordance with the manufacturer’s instructions. See Figure 12.

EXISTING VENT SYSTEMS

IMPORTANT RETROFIT VENTING INSTRUCTIONS

If this furnace is a replacement installation, ALWAYS INSPECT the existing vent system to be sure there are no obstructions, blockages, or signs of corrosion.

When the existing furnace is removed from a venting system serving other appliances, the venting is likely to be too large to properly vent the remaining attached appliances.

The following steps shall be followed with each appliance that remains connected to the common venting system, while the other appliances that remain connected to the common venting systems are not in operation.

NOTE:When the vent table permits more than one diameter of pipe for a connector or vent, the smallest permitted diameter must be used.

1. Seal any unused openings in the common venting system.

2. Visually inspect the venting system for proper size and horizontal pitch and determine that there is no blockage, restriction, leakage, corrosion or other deficiencies which could cause an unsafe condition.

3. Insofar as is practical, close all building doors, windows and all doors between the space where the appliances remaining connected to the common venting system are located.

Turn on clothes dryers and any appliance not connected to the common venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they will operate at maximum speed. Do not operate a summer exhaust fan. Close fireplace dampers.

4. Follow the lighting instructions. Place the appliance being inspected into operation. Adjust the thermostat so the appliance will operate continuously.

5. Test for spillage at the draft hood relief opening after 5 minutes of main burner operation. Use the flame of a match or candle, or smoke from a cigarette, cigar, or pipe.

6. After it has been determined that each appliance that remains connected to the common 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.

7. If improper venting is observed during any of the above tests, the common venting system must be resized. Refer to National Fuel Gas Code, ANSI Z223.1 and/or the Natural Gas Installation Code, CSA-B149.1 & .2.

IMPORTANT: It is permissible to run flexible gas connector inside the unit to a piece of black pipe. If local codes

DIRECT SPARK IGNITOR

allow the use of a flexible gas appliance connector, always use a new listed connector. Do not use a connector which has previously serviced another gas appliance.Massachusetts law limits flexible gas connectors to a maximum of 36”.

Install a ground joint union outside the cabinet to easily remove the control valve assembly. Install a manual shut-off valve in the gas line outside the cabinet. The valve should be readi-

ly accessible to turn the gas supply on or off. Install a drip leg in the gas supply line as close to the furnace as possible. Always use a pipe compound resistant to the action of liquefied petroleum gases on all threaded connections.

MANIFOLD

GAS VALVE

IMPORTANT: When making gas pipe connections, use a back-up wrench to prevent any twisting of the control assembly and gas valve.Do not overtighten the connection.

Any strains on the gas valve can change the position of the gas orifices in the burners. This can cause erratic furnace operation.

IMPORTANT: ENSURE that the fur- nace gas control valve not be subjected to high gas line supply pressures.

DISCONNECT the furnace and its individual shut-off valve from the gas supply piping during any pressure

testing that exceeds 1/2 PSIG (14” W.C.) (3.48 kPa).

GAS PRESSURE

IMPORTANT: Natural gas supply pressure should operate between 5" to

10.5”w.c. LP gas supply pressure should be 11” to 13” w.c. This pressure

must be maintained with all other gas-fired appliances in operation.

NOTE: Do not exceed a gas pressure of 13” w.c.

WARNING

ELEVATIONS ABOVE 2000 FT REQUIRETHATTHE FURNACE INPUT RATING BE ADJUSTED ANDTHAT THE SIZE OFTHE BURNER ORIFICES BE RE-CALCULATED BASED ON ELEVATION AND GAS HEATING VALUE.THE BURNER ORIFICES MAY (OR MAY NOT) NEED TO BE CHANGED.SEE THE SECTION TITLED“HIGH ALTITUDE INSTALLATIONS” OF THIS BOOK FOR INSTRUCTIONS.

The maximum gas supply pressure to the furnace should be 10.5” w.c. natural gas, or 13” w.c. LP gas. The minimum supply gas pressure to the gas valve should be 5" w.c. natural gas or 11" w.c. LP gas. A properly calibrated manometer is required for accurate gas pressure measurements.

Supply Gas Pressure Measurement.

A line pressure tap is on the inlet side of the gas valve.

1. With gas shut off to the furnace at the manual gas valve outside the unit, remove the input pressure tap plug.

2. Connect a U-Tube manometer to the pressure tap.

3. Turn on the gas supply and operate the furnace and all other gasfired units on the same gas line as the furnace.

4. Adjust the line gas pressure to supply:

A. 5” - 10.5” w.c. for natural gas. B. 11” - 13” w.c. for LP gas.

5. Shut off the gas at the manual gas valve and remove the U-Tube manometer.

6. Replace the pressure tap plug.

7. Turn gas on, and check for leaks.

NATURAL GAS:

If the supply gas line pressure is above the operating range, install an in-line gas regulator to the furnace. If supply gas line pressure is below the operating range, either remove any restrictions in the gas supply piping or enlarge the gas pipe. See Table 2.

LP GAS:

If the supply gas line pressure is above the operating range, have the LP supplier reduce the line pressure at the regulator. If supply gas line pressure is below operating range, have the LP supplier adjust the line pressure at the regulator. See Table 3.

NOTE: Depending on the amount of LP vapor and the outdoor ambient temperature, the LP storage tank may require supplemental heat to maintain proper pressure levels. Ensure LP storage tank does not drop below 15% capacity during heating season.

ADJUSTING OR CHECKING FURNACE INPUT

NATURAL GAS:

The maximum gas supply pressure to the furnace should be 10.5” W.C. for natural gas. The minimum gas supply pressure for purposes of input adjustment to the furnace should be 5” W.C.

A properly calibrated manometer or gauge is required for accurate gas pressure readings.

1. When adjusting the furnace input, the high fire input should be checked. The high fire manifold pressure should be 3.5' W.C. Follow these steps to be sure the furnace is high fire mode:

a. With a single stage thermostat,

the furnace runs for 12 minutes on low fire before shifting to high fire. To be certain that it is on high fire, jump terminals “W” and “W2” on the control board in the blower compartment.

b. With a two stage thermostat, set

the thermostat to its highest setting to keep the furnace operating in the high fire mode.

2. To adust high fire manifold pressure, remove the adjustment cover screw on the outlet end of the gas valve and turn the adjustment screw clockwise to increase the pressure and counterclockwise to reduce the pressure. Replace the cover screw securely.

3. The low fire manifold pressure should be 1.7" W.C. As mentioned above, the furnace remains in the low fire mode for 12 minutes upon a heat call with a single stage thermostat. With a two stage thermostat, disconnect the thermostat lead to the “W2” terminal on the control board and the furnace will remain in the low fire mode. To adjust the pressure, remove the regulator cover, on top of the valve, and adjust as noted under Step 2, above. After the adjustment replace the screw cover securely.

NOTE: Use a 3/32⬙ allen wrench for

making the pressure adjustment.

LP GAS:

Furnaces for use on LP gas, the LP gas supply pressure must be set between

11.0” and 13.0” W.C. 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. For elevations up to 7,000 feet, rating plate input ratings apply. For high altitudes (elevations 7,000 and over) and for any necessary major changes in the gas flow rate the orifice spud must be changed.

TO CHANGE ORIFICE SPUDS:

1. Shut off the manual main gas valve and remove the gas manifold.

2. Replace the orifice spuds.

3. Reassemble in reverse order.

4. Turn the gas supply back on and check for leaks.

5. Check for proper operation and set to proper manifold pressure.

ACCESSORIES

FIELD-INSTALLED OPTION ACCESSORIES

TWINNING: Most installations of (-)GPE/ (-)GLE furnaces cannot be twinned. However, a few exceptions exist for installations with some commercial evaporator coils. Consult the installation instructions of the coil to see if the furnace(s) can be twinned. If so, a twinning kit will be required and the part number for the kit can be found in the installation instructions for the coil.

ELECTRONIC AIR CLEANER

Line voltage power is supplied from the screw terminal “EAC”, see Figure 18, and a line voltageneutral screw terminal on the control board. This will power the electronic air cleaner whenever the blower is operating and delivering the recommended minimum CFM. The 50 and 75 KBTU models, which are capable of a maximum delivery of 1200 CFM, will operate the electronic air cleaner at 500 CFM and above. The 100 and 120 KBTU models, which are capable of a maximum delivery of 2000 CFM, will operate the electronic air cleaner at 800 CFM and above. These limits are set to prevent excessive production of ozone at the lower airflows of the furnaceand are based on average requirements of commercially available electronic air cleaners. Continuous fan speeds are selectable and some lower fan speeds may not deliver enough airflow to operate an electronic air cleaner. The IFC determines the minimum airflow necessary to operate an electronic air cleaner and will not turn on the electronic air cleaner unless the airflow is high enough for the EAC.

EAC AND HUMIDIFIER TERMINALS ON FURNACE CONTROL (IFC)

HUMIDIFICATION AND DEHUMIDIFICATION

HUMIDIFIER – The humidifier contacts (labeled “HUM OUT”) are “dry” contacts on the I.F.C. This means that the terminals are connected directly to the contacts of a board-mounted relay. The coil of the relay is controlled by the microprocessor of the IFC. The coil is engaged roughly any time the heat speed blower is engaged and (1) 24VAC is present on the thermostat terminal of the IFC labeled “HUM STAT” or (2) a communicating thermostat with humidification and dehumidification capability is installed with call for humidification present.

FIGURE 20

WIRING FOR OPTIONAL DEHUMIDIFICATIONWITH HUMIDIFICATION (WITH OPTIONAL HUMIDISTAT AND HUMIDIFIER) NOTE: CAN BE USED WITH COMMUNICATING OR NON-COMMUNICATING SYSTEMS

An optional 24VAC humidistat can be installed as shown in Figures 19 thru 54 (II thru IV). With the optional humidistat, two separate conditions must be met before humidification can begin 1). There must be a call for heat and the blower must be engaged and 2.) The humidistat must determine that there is a need for humidification.

Note: Dipswitch SW2-1 (labeled “ODD”) enables (“ON”) or disables (“OFF”) dehumidification operation. However, it has no affect on humidification operation. If this switch is set to the “ON” position and no humidistat is installed, the cooling

airflow will be permanently reduced by approximately 15% giving less than optimal performance and possibly causing problems. It is not recommended to leave this switch in the “ON” position without a humidistat installed.

Control of dehumidification in cooling and/or humidification in heating can be done with a variety of methods depending on whether there is a communicating thermostat or a humidistat available and depending on the type of operation desired.

With systems configured with communicating thermostats and condensers, dehumidification is controlled by the condenser and is not affected by the position of dipswitch SW2-1 or the voltage (or lack of voltage) at the thermostat terminal labeled “HUM STAT”.

To determine which wiring diagram and method to use, select from the following configurations:

A. HUMIDIFICATION CONTROL ONLY

WITH NO DEHUMIDIFICATION (REQUIRES OPTIONAL HUMIDIFIER).

A1. WITH COMMUNICATING

THERMOSTAT Humidifier control is included with the (-)HC-TST412MDMS (modulating, non-communicating) and (-)HC-TST550CMMS (full-color communicating) model thermostats. However, it is not included with the (-)HCTST501CMMS model communicating thermostat. The latter thermostat should not be used if humidification control is required. To wire the furnace for humidification control using the former thermostat, refer to the wiring diagram in Figure 19(I). Be sure not

to install the

jumper between “R” and “HUM

STAT” on the furnace control. Installing this jumper will operate the humidifier any time there is a heat call. Without the jumper, the humidification call from the thermostat must be active and a heat call must be present with the blower running.

A2. WITH NON-COMMUNICAT-

ING THERMOSTAT A2-1 CONTINOUS HUMID-

IFIER OPERATION DURING HEATING. For continuous humidifier operation during heating, refer to Figure 19 (I) and make sure to install the jumper between the thermostat terminals labeled “R” and “HUM STAT”. A separate humidistat is not required for this configuration and the humidifier will turn on whenever there is a call for heat and the blower is running.

A2-2 CONTROLED

HUMIDIFIER OPERATION USING A HUMIDISTAT (REQUIRES OPTIONAL HUMIDISTAT). Controlled humidification can be accomplished using a humidistat as shown in Figures 20 (II) or 21 (III). These figures show installation of a humidifier with external and internal power supplies respectively. Dehumidification operation will be disabled if the dipswitch SW2-1 is in the “OFF” position. If this switch is in the “ON” position, dehumidification control will be active.

B. DEHUMIDIFICATION CONTROL

WITH NO HUMIDIFICATION B1. For communicating ther-

mostats listed with this furnace, dehumidification is controlled automatically when selected at the thermostat and additional wiring is not necessary. The actual airflow demand (reduced for dehumidification) is requested of the furnace by the condenser.

B2. WITH NON-COMMUNICATING

THERMOSTAT (REQUIRES OPTIONAL HUMIDISTAT).

Control of dehumidification only (no humidification) can be accomplished by installing an optional humidistat as shown in Figure 22 (IV). The dipswitch SW2-1 must be set to the “ON” position. If this switch is not turned “ON”, dehumidification operation will not take place. Further, if this switch is “ON” and no humidistat is installed, airflow in cooling will be permanently reduced by approximately 15%.

C. HUMIDIFICATION AND DEHUMIFI-

CATION CONTROL (REQUIRES OPTIONAL HUMIDIFIER).

C1. WITH COMMUNICATING

THERMOSTAT

Humidifier control is included with the (-)HC-TST412MDMS (modulating, non-communicating) and (-)HC-TST550CMMS (full-color communicating) model thermostats. However, it is not included with the (-)HCTST501CMMS model communicating thermostat. Do not purchase the latter thermostat if humidification control is required. To wire the furnace for humidification and dehumidification control using the former thermostat, refer to the wiring diagram in Figure 19 (I). Be sure not between “R” and “HUM STAT” on the furnace control. Installing this jumper will operate the humidifier any time

C2. WITH NON-COMMUNICATING

THERMOSTAT (REQUIRES OPTIONAL HUMIDISTAT.)

For non-communicating thermostats, an optional humidistat must be installed. Controlled humidification and dehumidification can be accomplished using a humidistat as shown in Figures 20 (II) or 21 (III). These figures show installation of a humidifier with external and internal power supplies respectively. Dehumidification operation will be disabled if the dipswitch SW2-1 is in the “OFF” position. If this switch is in the “ON” position, dehumidification control will be active.

OTHER ACCESSORIES AVAILABLE

FOSSIL FUEL KIT (non-communicat-

ing systems only)

Use of a heat pump with the two stage furnace requires a heat pump thermostat used in conjunction with the fossil fuel kit. For proper operation use the following procedures:

a. With the RXPF-F01 kit, connectthe

thermostat “E” terminal, one side of the plenum switch, and the black wire from the fossil fuel kit to “W2” on the IFC.

b. For the RXPF-F02 kit, connect

“W” on the fossil fuel kit interface wiring board to “W2” on the IFC.

Regardless of which fossil fuel kit is used, when activated, the two stage furnace follows the sequence of operation for a single stage thermostat.

➢ IMPORTANT: ALWAYS FOLLOW THE MANUFACTURER’S FOSSIL FUEL KIT INSTRUCTIONS.

TWINNING: Most installations of (-)GPE and (-)GLE furnaces cannot be twinned. However, a few exceptions exist for installations with some commercial evaporator coils. Consult the installation instructions of the coil to see if the furnace can be twinned. If so, a twinning kit will be required and the part number for the kit can be found in the installation instructions for the coil.

This appliance is CSA certified for use with RXGW-B01 chimney adapter. Refer to kit installation instructions 92-101682-01.

TYPICAL WIRING FOR SELECT ACCESSORIES FOR COMMUNICATING RESIDENTIAL SYSTEMS

The Rheem Serial Communicating (CC2) system allows accessories to be connected to shut down the system in the event of a fault. Typical devices that can be connected are the drain overflow switch, smoke detector and freeze protection switch. There are two methods of connecting the switch to the system depending on the device configuration normally closed or normally open. The blower can run during a fault or the blower can shut off during a fault depending on how the system is connected. Please refer to local and/or state codes for installing these devices. The following operation applies only when BOTH the condenser and thermostat are serial communicating devices.

INSTALLATION OFTHIS FURNACE AT ALTITUDES ABOVE 2000 FT (610 m) SHALL BE IN ACCORDANCE WITH LOCAL CODES, OR IN THE ABSENCE OF LOCAL CODES,THE NATIONAL FUEL GAS CODE, ANSI Z223.1/NFPA 54 OR NATIONAL STANDARD OF CANADA, NATURAL GAS AND PROPANE INSTALLATION CODE, CAN B149.1.

Furnaces can be ordered from the factory already converted for high altitude elevations. The factory option for high altitude elevations would be ordered as a 278 option (example: a 75k BTU upflow furnace which is factory converted for high altitude elevations would have the model number (-)GPE07EAMKR). These factory converted furnaces come with pressure switches for high-altitude elevations already attached. Also, different burner orifices are installed at the factory which are one drill size smaller (#43 DMS) than standard (-)GPE/(-)GLE gas furnaces (#42 DMS). The smaller orifice is installed to accommodate for average heating values expected in most high altitude areas and a required 4% per thousand feet reduction in input as specified by the National Fuel Gas Code (NFGC). Specific orifices should always

be recalculated for all high altitude installations as outlined below. Orifices should be changed, if necessary, based on gas heating value and elevation.

34" 80 Plus furnaces installed above 2,000 ft. require the furnace to be derated 4% per thousand feet.

IMPORTANT: Factory installed orifices are calculated and sized based on a sea level Natural Gas heating value of 1075 BTU per cubic ft.

NOTE:Orifices are available through your local distributor.

Reference Tables 11, 12 and 13 for appropriate orifice sizing.

NOTE:Keep any parts removed during LP conversion procedure stored with the product literature for future use.

The following are examples of orifice sizing using the National Fuel Gas Code Appendix F:

LP GAS (TABLE 11)

LP Gas is a manufactured gas that has consistent heating value across most regions.

The NFGC guidelines are used with the following exception:

The recommended LP Gas high altitude orifice selections differ slightly in that the NFGC LP orifice chart, as they are not accurate for Rheem products. The National Fuel Gas Code LP orifices are based on an 11" of water column pressure at the orifice, which differs from products that use 10" of water column at the orifice. This difference requires a deviation from the NFGC orifice size recommendations. The Sea Level input
