Fig. 24 - Filter Installed for Side Inlet

NOTE: Side return-air openings can ONLY be used in Upflow configurations. Install filter(s) as shown in Fig. 24.

For bottom return-air applications, filter may need to be cut to fit some furnace widths. Install filter as shown in Fig. 25.

NOTE: Remove and discard bottom closure panel when bottom inlet is used.

Bottom Closure Panel

These furnaces are shipped with bottom closure panel installed in bottom return-air opening. This panel MUST be in place when side return air is used.

To remove bottom closure panel, perform following:

1.Tilt or raise furnace and remove two screws holding front filler panel. (See Fig. 26.)

2.Rotate front filler panel downward to release holding tabs.

3.Remove bottom closure panel.

4.Reinstall front filler panel and screws.

Gas Piping

Gas piping must be installed in accordance with national and local codes. Refer to NFGC in the U.S. Canadian installations must be made in accordance with CAN/CSA-B149.1-05 and all authorities having jurisdiction. Gas supply line should be a separate line running directly from meter to furnace, if possible. Refer to Table 3 for recommended gas pipe sizing. Risers must be used to connect to furnace and to meter. Support all gas piping with appropriate straps, hangers, etc. Use a minimum of one hanger every 6 ft. Joint compound (pipe dope) should be applied sparingly and only to male threads of joints. Pipe dope must be

!WARNING

FIRE OR EXPLOSION HAZARD

Failure to follow this warning could result in personal injury, death, or property damage.

-Connect gas pipe to furnace using a backup wrench to avoid damaging gas controls.

-Gas valve shutoff switch MUST be facing forward or tilted upward.

-Never purge a gas line into a combustion chamber. Never test for gas leaks with an open flame. Use a commercially available soap solution made specifically for the detection of leaks to check all connections.

-Use proper length of pipe to avoid stress on gas control manifold.

-If a flexible connector is required or allowed by authority having jurisdiction, black iron pipe shall be installed at furnace gas valve and extend a minimum of 2 in. (50.8mm) outside furnace casing.

-Protect gas valve from water and debris. Gas valve inlet and/or inlet piping must remain capped until gas supply line is permanently installed to protect the valve from moisture and debris. Also, install a sediment trap in the gas supply piping at the inlet to the gas valve.

Fig. 25 - Bottom Filter Arrangement

Install a sediment trap in riser leading to furnace. Trap can be installed by connecting a tee to riser leading to furnace so straight-through section of tee is vertical. Then connect a capped nipple into lower end of tee. Capped nipple should extend below level of gas controls. Place a ground joint union between gas control manifold and manual gas shutoff valve. (See Fig. 27.)

An accessible manual shutoff valve MUST be installed external to furnace casing and within 6 ft (1.8 m)of furnace. A 1/8-in. NPT (3.2mm) plugged tapping, accessible for test gauge connection, MUST be installed immediately upstream of gas supply connection to furnace and downstream of manual shutoff valve.

Gas line grommet (factory-supplied loose parts bag) should be used when installing gas piping. Gas line entry hole filler plug should be installed in unused gas line entry hole. (See Fig. 28.)
