Hazardous Locations

!WARNING

FIRE, EXPLOSION, INJURY OR DEATH

HAZARD

Improper location or inadequate protection could result in fire or explosion.

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. (457.2mm) above floor. 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. (See Fig. 5.)

Fig. 18 - Leveling Legs

INSTALLATION

Leveling Legs (If Desired)

When furnace is used in upflow position with side inlet(s), leveling legs may be desired. (See Fig. 18.) Install field-supplied, corrosion-resistant 5/16-in.(7.9mm) machine bolts and nuts.

NOTE: The maximum length of bolt should not exceed 1-1/2 in. (38.1mm).

1.Position furnace on its back. Locate and drill a 5/16-in. (7.9mm) diameter hole in each bottom corner of furnace. (See Fig. 18.) Holes in bottom closure panel may be used as guide locations.

2.For each hole, install nut on bolt and then install bolt and nut in hole. (Install flat washer if desired.)

3.Install another nut on other side of furnace base. (Install flat washer if desired.)

4.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.

Installation in Upflow or Downflow Applications

NOTE: For downflow applications, this furnace is approved for use on combustible flooring when special base (available from Manufacturer) Part No. KGASB is used. Special base is not required when this furnace is installed on Manufacturer’s Cased Coil Assembly or when Manufacturer’s Coil Box is used.

1.Determine application being installed from Table 1.

2.Construct hole in floor per dimensions specified in Table 1 and Fig. 19.

3.Construct plenum to dimensions specified in Table 2 and Fig. 19.

4.If special base (KGASB) is used, install as shown in Fig. 20.

5.If Manuracturer’s Cased Coil Assembly or Manufacturer’s Coil Box is used, install as shown in Fig. 21.

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 hand scanners, wide duct pliers or duct flange tool to bend flange back and forth until it breaks off. Be careful of sharp edges. (See Fig. 22.)

!CAUTION

UNIT MAY NOT OPERATE HAZARD

Failure to follow this caution may result in intermittent unit operation or performance satisfaction.

Do not bend duct flanges inward as shown in Fig. 22. This will affect airflow across heat exchangers and may cause limit cycling or premature heat exchanger failure. Remove duct flange completely or bend it inward a minimum of 210_F (99_C) as shown in Fig. 22.

Installation in Horizontal Applications

These furnaces can be installed in either horizontal left or right discharge position. In a crawlspace, furnace can either be hung from floor joist or installed on suitable blocks or pad. Furnace can be suspended from each corner by hanger bolts and angle iron supports. (See Fig. 23.) Cut hanger bolts (4 each 3/8-in. all-thread rod) to desired length. Use 1 X 3/8-in. flat washers, 3/8-in. lock washers, and 3/8-in. nuts on hanger rods as shown in Fig. 23. Dimples are provided for hole locations. (See Fig. 2.)

!CAUTION

UNIT MAY NOT OPERATE HAZARD

Failure to follow this caution may result in intermittent unit operation or performance satisfaction.

The entire length of furnace MUST be supported when furnace is used in a horizontal position to ensure proper draining. When suspended, bottom brace supports sides and center blower shelf. When unit is supported from the ground, blocks or pad should support sides and center blower shelf area.
