SECTION III: UNIT INSTALLATION

LOCATION
Access for servicing is an important factor in the location of any furnace. Provide a minimum of 24 in. (61 cm) in front of the furnace for access to the heating elements and controls. This access can be provided by a closet door or by locating the furnace 24 in. (61 cm) from a facing wall or partition.

FURNACE CLEARANCE
This furnace is approved for 0 in. clearance to combustible material on all or any part of the furnace exterior and the inlet or outlet duct work except as stated below. For furnaces installed in up flow application, there must be a minimum of 1 in. (2.54 cm) clearance from the bare surface of the outlet duct work for a distance of 3 ft (91.4 cm) from the supply air opening. This requirement is met if the duct is wrapped with an insulating material at least 1 in. thick that has an R-value of at least R-4.

RETURN AIR
In order for the furnace to work properly, a closet or alcove must have a certain total free area opening for return air.

For Heating Only Furnace
A minimum of 200 sq in. (1290 sq cm) free area opening. Use any return grille with a minimum of 200 sq in. free opening.

For Up to 4 Ton AC and HP Applications (Standard Blower)
A minimum of 250 sq in. (1613 sq cm) free area opening. The standard blower assembly supplied with the furnace is capable of handling up 4 ton AC applications. Use any return grille with a minimum of 250 sq in.(1613 sq cm) free area opening.

For 5 Ton AC Applications (Accessory Blower)
A minimum of 350 sq in. (2129 sq cm) free area opening. Use 5 ton AC blower accessory 3500-7911. Use any return grille with a minimum of 350 sq in. (2129 sq cm) free area opening with 5 ton AC blower accessory 3500-7911. The up flow return air box accessory 3500-8982 can also be used with 5 ton AC blower accessory 3500-7911.

Location
For downflow applications, the return air opening can be located in a closet front door, sidewall above the furnace casing, or louvered door on the furnace. If the opening for the return air is located in the floor, sidewalls, or closet door anywhere below the furnace casing height, 6 in. minimum clearance must be provided on the furnace side where return is located to provide for proper airflow. For up flow installations, a closet that is 32 in. wide by 30 in. deep with a 30-inch wide door is necessary. This is not required if there is a return grille installed below furnace. The return air opening can be located in a closet front door, sidewall above the furnace casing, or louvered door on the furnace. If the opening for the return air is located in the floor, sidewalls, or closet door anywhere below the furnace casing height, 6 in. (15.2 cm) mini-mum clearance must be provided on the furnace side where return is located to provide for proper airflow. See Figure 2. The 6 in. (15.2 cm) minimum clearance is not required if there is a return grille installed above the furnace height. This return grille cannot start more than 3 ft above the furnace height. If the louvers in the closet door have as much airflow area as the EB louvered furnace door, only 1 in. clearance is required.
Alcove and Closet Clearances
When installing the furnace in a separate closet or room that is accessible only through an outside door, a minimum of 200 sq in. (1290 sq cm) free opening for return air must be provided. The supply and return air must be ducted, securely attached, and sealed to the furnace casing if there are grilles in the outside door to the closet. Openings where ducts pass through walls, the floor, or the ceiling must be sealed to prevent air leakage into or from the closet and the living area
Up flow Closet Clearances
Provisions must be made to permit the return of circulating air from all rooms and living spaces, except the bathroom(s), to the circulating air supply inlet of the furnace. Failure to comply may cause improper heating and may cause the furnace to cycle on the limit.

DUCT SYSTEM DESIGN
An electric furnace is designed to operate at a given static pressure. To ensure proper airflow through the furnace, the distribution system must be designed so the static pressure external to the furnace does not exceed the static pressure rating shown on the furnace rating plate. The number, size, and placement of registers must be such that even distribution of heat is provided throughout the home.

SECTION IV: ELECTRIC FURNACE INSTALLATION

7900 SERIES DUCT CONNECTOR FOR EBE DOWN-FLOW
The duct connector is designed to eliminate a sub-base requirement. Table 1 provides the part number of the duct connector needed.

•  Indicates connector above or below could be used, depending on tolerance in floor to duct dimension.
•  Indicates connector above could be used, depending on tolerance in floor to duct dimension.
• Indicates connector below could be used, depending on tolerance in floor to duct dimension.

DUCT CONNECTORS (7990 SERIES) Duct Connector Depth (7990 Series)
These duct connectors connect the furnace to an under the floor supply duct system. The furnace can be installed on combustible flooring with-out a separate sub-base.
Duct Connector Dimensions (7990 Series)

INSTALLATION OF SCREW ATTACHMENT DUCT CONNECTOR (7990 SERIES)

1. Make floor cut out as shown

2. Determine the depth of the floor cavity from the surface of the floor to the top of the supply air duct and select the appropriate duct connector from the chart.

3. Place locating bracket (supplied with the duct connector) to the back edge of the floor opening.

4. Duct Connector Screw Attachment (7990 Series)

5. Apply a water based duct sealant to the 1/2 in. supply duct attachment flange of the duct connector.
   Determine which of the four positions the duct connector best centers over the supply duct and insert it through the floor cutout. When properly aligned with the supply duct, secure the duct con-nector to the floor with nails, flat head screws, or staples.

6. Use screws as required to secure duct connector to supply duct.

7. Cut out the opening to the supply duct. If sealant has not been used, tape the mating flanges to provide a good air seal.

NOTICE
Duct sealant and tape must be classified as meeting HUD Standard 3280.715, U.L. Standard 181A.

INSTALLATION OF TAB ATTACHMENT DUCT CONNECTOR (7990 SERIES)

1. Make floor cut out as shown in Figure 6.
2. Determine the depth of the floor cavity from the surface of the floor to the top of the supply air duct and select the appropriate duct connector from the chart.
3. Place locating bracket (supplied with the duct connector) to the rear of the floor area for the furnace.
4. Determine which of the four positions the duct connector best centers over the supply duct and insert it through the floor cutout.
5. Mark cut-out location on the supply duct and remove the duct connector.
6. Cut out the opening to the supply duct.
7. Bend tabs down through and back up under the supply duct.
8. Secure the duct connector to the floor with nails, flat head screws, or staples.

The duct connector is designed for use on ducts down to 12 in. in width. When using the connector on smaller width ducts, there is insufficient clearance to bend the tabs on two sides of the duct connector.
In such cases, the tabs can be attached to the sides of the duct by using sheet metal screws or other suitable fasteners. Holes for sheet metal screws are provided in three tabs on each side of the duct connector. If more than three tabs need to be used to provide a more secure and air tight connection, the remaining tabs can also be fas-tened to the duct with screws after drilling the required screw holes.

INSTALLATION OF THE FURNACE

1. Remove the front panels and set the furnace onto the duct connector. Slide it back until the rear of the unit engages the locator bracket.
2. Secure the front of the furnace with two screws at the provided mounting holes.
3. Secure the top of the furnace to a structural member by screwing through the strap at the top of the furnace. The strap can be moved to any of the holes located along the top back of the furnace. The installer may provide an equivalent method, such as screws through the casing side.

WIRING

Furnace wiring is complete except for the power supply and the thermo-stat wires. See wiring diagrams for wire and fuse size. See Table 2 for ground wire sizes. Thermostat wires connect through the side of the furnace and must be no smaller than 22 gauge. Power wires can enter through the side of the unit or through the auxiliary entrance located in the bottom of the unit. When bringing wiring through the bottom of the furnace, cable connectors must be installed to hold wiring in place and relieve any strain on the wiring. These connectors also serve as a seal between the furnace and the floor, so additional sealing is not required.
NOTICE
The furnaces are equipped with either one or two 60 amp circuit breakers. These circuit breakers protect the wiring inside of the furnace in the event of a short circuit. Additionally, these breakers pro-vide a means of disconnecting the power to the unit. The circuit breakers in the furnace are not meant to protect the branch circuit wiring between the furnace and the home’s breaker panel. General wire and breaker sizes are shown in Table 2. If sheathed cable is used, refer to National Electrical Code, Canadian Electrical Code and local codes for additional requirements concerning supply circuit wiring.
IMPORTANT: All installation on field wiring must be rated at 60ºC or higher.

WARNING
For personal safety be sure to turn the electrical power OFF at the household service box and at the furnace circuit breakers before attempting any service or maintenance operations. Homeowners should never perform any maintenance which requires opening electric box door.
Furnace is equipped with a protective shield over field wiring con-nection. When field wiring is completed, shield must be replaced to prevent hazard of electrical shock when using furnace disconnect.

SECTION V: THERMOSTAT INSTALLATION

The adjustable heat anticipator in the thermostat is pre-set at 0.4 amps. This setting must be checked at the time of installation.
In some cases the thermostat may be a self-setting type, in which case there is no amp setting on the thermostat, eliminating the need for any field adjustment.
The thermostat must be located on an inside wall in an open area to more closely regulate average room air, preferably, where there is air movement back to furnace. Care must be used to locate the thermostat away from hot air discharge openings and lights, for example. The height of the thermostat location is important. The thermostat must be located 52 in. to 66 in. (132 cm to 167.6 cm) above the floor. This is sometimes called the comfort zone.
If a condenser with its own transformer shares a Heat/Cool thermostat with this furnace, use a thermostat with isolating contacts to prevent interconnection of Class II 24 V Systems.
Cycle the furnace using the thermostat to make sure it operates correctly.
Maintenance and operating instructions are in the customer envelope accompanying the furnace. Give the customer envelope to the home owner.

SECTION VI: AIR CONDITIONING ACCESSORIES EBE/EUE FURNACE MODELS

NOTICE
EUE furnaces are shipped with the coil shelf in the top orientation. This is not a defect. For application, turn the unit 180° vertically so the coil shelf is in the bottom orientation.
EBE and EUE furnaces are factory equipped with a blower, coil shelf, and control system for add-on air conditioning and heat pump. The coil shelf accessory 3500-8981 can be used to replace current and older EBE and EUE coil shelfs.
