2.When completed, downflow subbase, plenum, and furnace (or coil casing when used) should be installed as shown in Fig. 6.

Step 4—Horizontal Attic Installation

Do not install furnace on its back; safety control operation will be adversely affected. Never connect return-air ducts to the sides or back of the furnace. A failure to follow this warning could result in fire, personal injury, or death.

The furnace can be installed horizontally on either the left-hand (LH) or right-hand (RH) side. A typical attic installation is shown in Fig. 8.

CONSTRUCT WORKING PLATFORM

Construct working platform on location where all required furnace clearances are met. (See Table 1 and Fig. 8.)

INSTALL FURNACE

1.Position furnace in desired location.

2.Connect gas supply pipe. See Fig. 8 for typical piping entry.

3.Connect supply- and return-air ducts.

4.Install field-supplied filter retainers as indicated in Fig. 11 and Table 4 before connecting return-air duct to furnace.

5.Install 24- X 24-in. sheet metal shield on platform in front of louvered control panel as shown in Fig. 8.

→Step 5—Horizontal Crawlspace Installation

The furnace can be installed horizontally with either the LH or RH side up. In a crawlspace, furnace can either be hung from floor joist (see Fig. 9) or installed on suitable blocks or pad. (See Fig.

10.) The furnace can be suspended from each corner by hanger bolts (4 each 3/8-in. all-thread rod) cut to desired length, 1- X 3/8-in. flat washer, 3/8-in. lockwasher, and 3/8-in. nut. Dimples are provided for hole locations. (See Fig. 1.)

Since horizontal crawlspace installation is very similar to attic installation, refer to Step 4. The installation of a sheet metal shield in front of louvered control panel is covered in Step 4. For a crawlspace installation, this same sheet metal shield must be installed above louvered control panel. Extend sheet metal shield over furnace top far enough to cover gas pipe entry hole.

Step 6—Filter Arrangement

Never operate unit without a filter or with filter access door removed. A failure to follow this warning could result in fire, personal injury, or death.

The 2 factory-supplied filters are shipped in the blower compart- ment. After return-air duct has been connected to furnace, install filters in a V-formation inside return-air plenum. See Fig. 11 and Table 4 for horizontal applications. Horizontal filter retainers must be field supplied. See Fig. 12 for downflow applications.

Step 7—Gas Piping

→Gas piping must be installed in accordance with national and local codes. Refer to the NFGC NFPA 54-1996/ANSI Z223.1-1996.

Canadian installations must be installed in accordance with NSC- NGPIC and all authorities having jurisdiction.

The gas supply line should be a separate line directly from the meter to the furnace, if possible. Refer to Table 5 for recom- mended gas pipe sizing. Risers should be used to connect to the furnace and to the meter.
