IV. HAZARDOUS LOCATIONS

18-IN. MINIMUM

TO BURNERS

A93044

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. 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 accor- dance with requirements of National Fire Protection Association, Inc.

INSTALLATION

I.LEVELING LEGS (IF DESIRED)

When furnace is used in upflow position with side inlet(s), leveling legs may be desired. (See Fig. 12.) Install field-supplied, corrosion-resistant 5/16-in. machine bolts and nuts.

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

1.Position furnace on its back. Locate and drill a 5/16-in. diameter hole in each bottom corner of furnace. (See Fig. 12.) 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.

II.INSTALLATION IN UPFLOW OR DOWNFLOW APPLICATIONS

NOTE: This furnace is approved for use on combustible flooring when special base (available from manufacturer) Part No. KGASB0201ALL is used. Special base in not required when this furnace is installed on manufacturer's Coil Assembly Part No. CD5 or CK5, or Coil Box Part No. KCAKC is used.

Fig. 12ÐLeveling Legs

1.Determine application being installed from Table 1.

2.Construct hole in floor per dimensions specified in Table 1 and Fig. 13.

3.Construct plenum to dimensions specified in Table 1 and Fig. 13.

4.If downflow subbase (KGASB) is used, install as shown in Fig. 14.

If coil assembly CD5 or CK5 or Coil Box KCAKC is used, install as shown in Fig. 15.

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. (See Fig. 16.)

WARNING: Do not bend duct flanges inward as shown in Fig. 16. 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° as shown in Fig. 16.
