Installer’s Guide SAFETY SECTION The following safety practices and precautions must be followed during the installation, servicing, and operation of this furnace. 1. Use only with the type of gas approved for this furnace. Refer to the furnace rating plate. 2. Install this furnace only in a location and position as specified in “Location and Clearances” (page 4), of these instructions. 3.
Safety signal words are used to designate a degree or level of seriousness associated with a particular hazard. The signal words for safety markings are WARNING and CAUTION. a. WARNING indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. b. CAUTION indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It is also used to alert against unsafe practices and hazards involving only property damage.
Installer’s Guide ! CAUTION ▲ To prevent shortening its service life, the furnace should not be used as a “Construction Heater” during the finishing phases of construction until the requirements listed in item 9, a-g of the safety section of this publication have been met. Condensate in the presence of chlorides and fluorides from paint, varnish, stains, adhesives, cleaning compounds, and cement create a corrosive condition which may cause rapid deterioration of the heat exchanger.

Installer’s Guide UPFLOW INSTALLATION Standoffs and screws (See Figure 1) are included with the cased coils for attachment to the furnace. There are clearance alignment holes near the bottom of the coil wrapper. Drill screws are used to engage the furnace top flanges. The standoff is inserted into the cabinet alignment hole. The drill screws are inserted through the standoffs then screwed into the furnace flange. The coil is always placed downstream of the furnace airflow.
Installer’s Guide The furnace may be placed horizontally in a crawl space on a pad or other noncombustible material which will raise the unit for sufficient protection from moisture. The furnace must be supported at both ends and the middle when installed horizontally. 4 Provisions for combustion and ventilation air shall be made in accordance with latest edition of Section 5.3, Air for Combustion and Ventilation, of the National Fuel Gas Code, ANSI Z223.1 — CAN/CGA B149.

Installer’s Guide DUCT CONNECTIONS Air duct systems should be installed in accordance with standards for air conditioning systems, National Fire Protection Association Pamphlet No. 90. They should be sized in accordance with ACCA Manual D or whichever is applicable. Central furnaces, when used in connection with cooling units, shall be installed in parallel or on the upstream side of the cooling coil to avoid condensation in the heat exchanger.
Installer’s Guide 9. The horizontal installation of the upflow furnace requires an external filter section. Do NOT use the bottom return filter within the furnace. Filter kits are available for horizontal applications. 10. Connect duct work to furnace. See Outline Drawing for supply and return duct size and location. Flexible duct connectors are recommended to connect both supply and return air ducts to the furnace.

Installer’s Guide GENERAL VENTING THIS FURNACE MUST BE VENTED TO THE OUTDOORS. THESE FURNACES ARE INDUCED DRAFT VENTED AND MUST NOT BE CONNECTED TO ANY VENT SERVING ANOTHER APPLIANCE. PLEASE NOTE THAT THESE FURNACES USE POSITIVE-PRESSURE VENT SYSTEMS. Proper venting is essential to obtain maximum efficiency from a condensing furnace. Proper installation of the vent system is necessary to assure drainage of the condensate and prevent deterioration of the vent system.
Installer’s Guide PVC VENT FITTING MATERIAL These fittings are available from your Gas Furnace Distributors. 2. After checking pipe and socket for proper fit, wipe socket and pipe with cleaner-primer. Apply a liberal coat of primer to inside surface of socket and outside of pipe. DO NOT ALLOW PRIMER TO DRY BEFORE APPLYING CEMENT. 3. Apply a thin coat of cement evenly in the socket.

Installer’s Guide ▲! CAUTION When the vent pipe is exposed to temperatures below freezing, i.e., when it passes through unheated spaces, etc., the pipe must be insulated with 1/2 inch (22.7 mm) thick Armaflex-type insulation or equal. If the space is heated sufficiently to prevent freezing, then the insulation would not be required. If domestic water pipes are not protected from freezing then it is assumed the space meets the condition of a heated space.

Installer’s Guide CONDENSATE DRAIN INSTRUCTIONS ! CAUTION ▲ IT IS RECOMMENDED THAT A DRAIN PAN BE INSTALLED UNDER THE FURNACE TO PREVENT PROPERTY DAMAGE, PERSONAL INJURY OR DEATH FROM LEAKING CONDENSATE. VERTICAL APPLICATIONS Upflow furnace - The connection tubing for left and right side drainage is shipped in the blower compartment. Install the connection tubing from the trap to the side of the unit and trim all excess tubing to avoid kinks.
Installer’s Guide The trap must be repositioned to the exterior of the cabinet. Remove the trap from its present location and reposition the trap outside of the unit, through the long circular hole, next to the secondary recuperative cell. Remove the larger drain line (from the secondary cell) and trim to fit between the secondary cell and the new trap location. On upflow units, plug the hole in the blower deck where the tube went through.
Installer’s Guide ELECTRICAL CONNECTIONS Make wiring connections to the unit as indicated on enclosed wiring diagram. As with all gas appliances using electrical power, this furnace shall be connected into a permanently live electric circuit. It is recommended that furnace be provided with a separate “circuit protection device” in the electric circuit.

Failure to follow this warning could result in property damage, personal injury or death. Lighting instructions appear on each unit. Each installation must be checked out at the time of initial start up to insure proper operation of all components. Check out should include putting the unit through one complete cycle as outlined below.
Installer’s Guide AIRFLOW ADJUSTMENT Check inlet and outlet air temperatures to make sure they are within the ranges specified on the furnace rating nameplate. If the airflow needs to be increased or decreased, see the wiring diagram for information on changing the speed of the blower motor. ! WARNING ▲ Disconnect power to the unit before removing the blower door. Failure to follow this warning could result in property damage, personal injury or death.
Installer’s Guide 8. RESET AFTER BURNER BOX LIMIT SHUTDOWN If the furnace shuts down, one thing that can be checked is the burner box temperature limit switch. It is located on the bottom of the burner box. The vent and combustion air inlet terminations should be checked for blockage. If blockage exists, clear the problem and then the reset button may be depressed. If there is no blockage of the terminations, the limit switch must be reset by a qualified servicer.
