A horizontal left furnace application is where furnace blower is located to the right of combustion and controls section of furnace, and conditioned air is discharged to the left.

CAUTION: Local codes may require a drain pan under entire furnace and condensate trap when a condensing furnace is used in an attic application or over a finished ceiling. See Electrical Connection section for J-Box relocation. The condensate trap must be removed from the factory-installed blower shelf location and relocated in selected application location as shown in Fig. To relocate condensate trap from the blower shelf to desired location, perform the following:.

Install condensate trap into casing hole by inserting tube connection stubs through casing hole and rotating until tabs snap into locking position. Install drain tube coupling factory-supplied in loose parts bag into collector box drain tube blue label which was previously connected to condensate trap.

Connect large diameter drain tube and clamp factorysupplied in loose parts bag to drain tube coupling, extending collector box drain tube. Route extended tube blue label to condensate trap and cut to appropriate length. Extend collector box tube green label which was previously connected to the condensate trap by splicing to small diameter tube factory-supplied in loose parts bag.

Route extended collector box pressure tube to relief port connection on the condensate trap. Use smaller diameter tube factory-supplied in loose parts bag to extend tube disconnected in item 1. Between blower shelf and inducer housing. Behind inducer motor bracket. Between inducer motor and pressure switch. Condensate Trap Freeze Protection. Construct a Working Platform.

Construct working platform where all required furnace clearances are met. The drain connection to condensate trap must also be properly sloped to an open drain.

NOTE: Combustion-air and vent pipes are restricted to a minimum length of 5 ft. See Table 6. NOTE: A in. This recommendation is to reduce excessive condensate droplets from exiting the vent pipe.

A horizontal right furnace application is where furnace blower is located to the left of combustion and controls section of furnace, and conditioned air is discharged to the right. CAUTION: Local codes may require a drain pan under entire furnace and condensate trap when a condensing furnace is used in attic application or over a finished ceiling. A IN. Install removed clamp and plug into UPPER collector box drain tube blue label which was previously connected to condensate trap.

Tube does not need to be cut. Use inducer housing drain extension tube violet label and factory-supplied in loose parts bag to connect LOWER inducer housing drain connection to condensate trap.

Determine appropriate length, cut, and connect tube to condensate trap. NOTE: For proper furnace operation, install furnace so that it is. NOTE: Combustion-air and vent pipes are restricted to a mini-. Failure to follow these return-air temperature limits may affect reliability of heat exchangers, motors, and controls. Safety control operation will be adversely affected. Never connect return-air ducts to back of furnace. Failure to follow this warning could result in fire, personal injury, or death.

If operation of furnace is required during construction, use clean outside air for combustion and ventilation. Compounds of chlorine and fluorine, when burned with combustion air, form acids which will cause corrosion of heat exchangers.

Some of these compounds are found in paneling, dry wall adhesives, paints, thinners, masonry cleaning materials, and many other solvents commonly used in construction process.

Excessive exposure to contaminated combustion air will result in safety and performance related problems. Provide ample space for servicing and cleaning. Always comply with minimum fire protection clearances shown on unit's clearance to combustibles label. Locate furnace where available electric power and gas supplies meet specifications on furnace rating plate. The cooling coil must be installed parallel with or on downstream side of furnace to avoid condensation in heat exchanger.

When installed parallel with a furnace, dampers or other means used to control flow of air must prevent chilled air from entering furnace. If dampers are manually operated, they must be equipped with a means to prevent operation of either unit unless damper is in full-heat or full-cool position. WARNING: When furnace is installed in a residential garage, it must be installed so that burners and ignition sources are located a minimum of 18 in.

The furnace must be located or protected to avoid physical damage by vehicles. When furnace is installed in a public garage, airplane hangar, or other building having a hazardous atmosphere, unit must be installed in accordance with requirements of National Fire Protection Association, Inc.

When furnace is used in upflow position with side inlet s , leveling legs may be desired. Position furnace on its back. Holes in bottom closure panel may be used as guide locations. For each hole, install nut on bolt and then install bolt and nut in hole. Install flat washer if desired. Install another nut on other side of furnace base. Adjust outside nut to provide desired height, and tighten inside nut to secure arrangement. NOTE: Bottom closure must be used when leveling legs are used.

See Bottom Closure Panel section. NOTE: For downflow applications, this furnace is approved for use on combustible flooring when special base available from manufacturer Part No. Special base in not required when this furnace is installed on manufacturer's Coil Assembly Part No.

Determine application being installed from Table 1. Construct hole in floor per dimensions specified in Table 1 and Fig. Construct plenum to dimensions specified in Table 1 and Fig.

If Coil Assembly Part No. NOTE: Remove furnace perforated, discharge duct flanges when they interfere with mating flanges on coil on downflow subbase. To remove furnace perforated, discharge duct flange, use wide duct pliers or duct flange tool to bend flange back and forth until it breaks off.

Be careful of sharp edges.
