CAUTION
!
UNIT MAY NOT OPERATE
Failure to follow this caution may result in intermittent unit
operation or performance satisfaction.
For airflow requirements above 1800 CFM, see Air
Delivery table in Product Data literature for specific use of
single side inlets. The use of both side inlets, a combination
of 1 side and the bottom, or the bottom only will ensure
adequate return air openings for airflow requirements above
1800 CFM.
NOTE: Side return- -air openings can be used for return air
connections. Install filter(s) as shown in Fig. 14.
For bottom return- -air applications, filter may need to be cut to fit
some furnace widths. Install filter as shown in Fig. 15.

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 2 screws holding front filler
panel. (See Fig. 16.)
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 NSCNGPIC 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 1 hanger every 6 ft. (1.8
M). Joint compound (pipe dope) should be applied sparingly and
only to male threads of joints. Pipe dope must be resistant to
propane gas.
