Page 9: Furnace Sizing
3.0 FURNACE SIZING The maximum hourly heat loss for each heated space shall be calculated in accordance with the procedures described in the manuals of the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI), or by any other method which is suitable for local conditions, provided the results obtained are in substantial agree- ment with, and not less than those obtained using the procedure described in their manuals. -
Page 10: Location Of Unit
4.0 LOCATION OF UNIT GENERAL GUIDELINES 1. Select a location where the exhaust and combustion air piping can be routed between the furnace and their terminations with a minimum of lengths and fi ttings. Be sure to check that the proposed termination location will meet code requirements with respect to location and minimum clearances. -
Page 11: Installation In Upflow Position
INSTALLATION IN UPFLOW POSITION UPFLOW INSTALLATION: Vent positioning, pressure switch location and drain locations shall be performed in ac- cordance with instructions in the appropriate sections of this manual. NON-SUSPENDED INSTALLATION: Maintain clearances to combustibles as outlined in Figure 1, Table B. The furnace must be supported in such a way as to not allow twisting or sagging of the cabinet. -
Page 12: Combustible Clearances
5.0 COMBUSTIBLE CLEARANCES Table B provides the certifi ed clearances to combustibles and dimensional information. Also see the appliance rating plate affi xed to the furnace for specifi c model number, serial number and clearance to combustibles information. IMPORTANT THIS FURNACE REQUIRES A MINIMUM OF 24” (610 mm) OF FRONT CLEARANCE FOR SERVICE PURPOSES. -
Page 13: Ductwork
6.0 DUCTWORK Proper airfl ow is required for the correct operation of this furnace. Insuffi cient airfl ow may cause erratic opera- tion, could cause the furnace to cycle on the high temperature limit, and may damage the heat exchanger. Excessive airfl... -
Page 14: Ductwork Steps
DUCTWORK STEPS 1. Position the furnace to minimize ductwork length and fi ttings. 2. Cut open a return air inlet. The choices are furnace bottom, either side, or any combination thereof (i.e., two sides or a side and the bottom).In all cases, cut the return air opening the full width of the return air markers on the side panel. -

Page 25: Location
10.5 LOCATION Avoid locating the terminals where the fl ue gas could become stagnant and allow recirculation into the combus- tion air intake. Avoid locating the terminal in locations where dripping condensate may cause problems such as sidewalks, pa- tios, above planters, near windows where exhaust gases may cause fogging, etc. Avoid locating the termination too close to shrubs and other vegetation. - Page 26 If more than two furnaces are being installed in close proximity, each additional combustion air intake and exhaust termination set shall not terminate less than 12 in (305 mm) apart. Note: Canadian installations of 120000 Btu/hr require 3 ft (915 mm).

Page 29: Routing Options
11.0 ROUTING OPTIONS This furnace must be installed in the upfl ow position only. Figure 22 on the following page shows the three vent installation positions. The installer must consider the following services: gas pipe, electrical power, drain trap, in- take and exhaust vents. -
Page 30: Condensate Drains
11.2 CONDENSATE DRAINS The furnace may condense as much as a 4½ pounds of water per hour (approximately 2 imperial quarts, 2½ U.S. quarts or 2¼ liters). It is necessary to make provisions for draining the condensate away. The furnace is supplied with a drain trap assembly. - Page 31 IMPORTANT: CONNECT ½” TEE FITTING (FIELD SUPPLIED) TO THE OUTLET OF THE CONDENSATE TRAP. WARNING THERE MUST NOT BE ANY OPENINGS BETWEEN THE BLOWER DIVISION PANEL AND THE COMBUSTION COMPARTMENT. THE BLOWER COMPARTMENT IS UNDER GREATER SUCTION THAN THE COMBUSTION COMPARTMENT AND CAN PULL COMBUSTION AIR FROM THE BURNERS AND CAUSE INCOMPLETE COMBUSTION AND ERRATIC FURNACE OPERATION.

11.4 DRAIN HOSE INSTALLATION 1. Connect one end of the 5/8” tubing (in parts bag) to the most direct drain outlet on the front manifold cover, and the other end to the larger elbow on the condensate trap assembly. Cut excess tubing if necessary and hold in place with the supplied plastic hose clamps (in parts bag). -
Page 34: Priming Condensate Trap
11.4.2 PRIMING CONDENSATE TRAP IMPORTANT: THE CONDENSATE DRAIN TRAP ASSEMBLY SHOULD BE FULL OF WATER (PRIMED) BEFORE STARTING THE FURNACE. TO FILL THE CONDENSATE DRAIN TRAP ASSEMBLY, TEMPORARILY REMOVE THE VENT DRAIN HOSE FROM THE EXHAUSTER ASSEMBLY ELBOW/DRAIN FITTING, AND POUR APPROXIMATELY ONE CUP OF WATER DOWN THE HOSE. -
Page 35: Condensate Neutralizers
A ½” PVC coupling or bushing will fi t snug over the ½” rubber hose. A ¾” CPVC coupling or bushing will fi t snug over the 5/8” rubber hose. This method ensures a water tight seal and also allows the condensate trap to be easily removed for service. -
Page 36: Gas Supply And Piping
12.0 GAS SUPPLY AND PIPING 12.1 GAS SUPPLY WARNING THIS FURNACE IS FACTORY EQUIPPED TO BURN NATURAL GAS ONLY. CONVERSION TO LP GAS REQUIRES A NATURAL GAS TO LP CONVERSION KIT (W370-0018). FAILURE TO USE THE PROPER CONVERSION KIT CAN CAUSE FIRE, EXPLOSION, CARBON MONOXIDE POISONING, PROPERTY DAMAGE, PERSONAL INJURY OR LOSS OF LIFE. -
Page 37: Gas Inlet Pressure
IMPORTANT: ALWAYS USE A BACKUP WRENCH TO PREVENT TWISTING OF THE GAS VALVE. ANY STRAINS ON THE GAS VALVE CAN AFFECT POSITIONING OF THE ORIFICES RELATIVE TO THE BURNERS. THIS COULD RESULT IN FAULTY BURNER OPERATION. Install a manual gas shut-off valve and dirt pocket as close to the furnace as possible. Some local codes call for the manual gas shut-off valve to be located between 4 (1.2 m) to 5 feet (1.5 m) above fl... -
Page 38: Conversions
13.0 CONVERSIONS 13.1 HIGH ALTITUDE CONVERSION In Canada, the modifi cations for high altitude are based on a 10% reduction of input capacity for elevations from 2000 - 4500 feet (610 m - 1372 m). In the United States, the modifi cations for high altitude are based on a 4% reduction of input capacity for every 1000 feet (305 m) above 2000 feet (610 m) above sea level. -

Page 45: Initial Startup Procedures
17.0 INITIAL STARTUP PROCEDURES This furnace is equipped with a HSI (Hot Surface Ignition) device. Each time that the room thermostat calls for heat, the HSI lights the main burners directly. See the lighting instructions on the furnace. When the gas supply is initially connected to the furnace, the gas piping may be full of air. In order to purge this air, it is recommended that the ground union be loosened until the odor of gas is detected. -

Page 66: Routine Maintenance By Homeowner
4.0 ROUTINE MAINTENANCE BY HOMEOWNER AIR FILTER CAUTION DO NOT OPERATE YOUR FURNACE OR AIR CONDITIONER FOR EXTENDED PERIODS OF TIME WITHOUT AN AIR FILTER. A portion of the dust entrained in the air may temporarily lodge in the air duct runs and the supply registers. Any recirculated dust particles will be heated and charred by coming into contact with the heat exchanger. -

• Water should fl ow easily through the condensate drain line. You may be able to observe this while the furnace is operating if your condensate drain line from the drain trap assembly terminates at a fl oor drain or sump pit. If clear plastic was used, it may yellow with age; however, the contents should be reasonably clear. -
Page 68: Furnace Appearance
FURNACE APPEARANCE The furnace exterior fi nish is a durable automotive like coating. It may be washed with mild soap if necessary. Galvanized metal surfaces require no maintenance. CLEANING It is advisable to keep dust build-up on warm surfaces to a minimum, since dust, in some cases, can be a combustible. -
