7 - If intake and exhaust piping must be run up a
side wall to position above snow accumulation or
other obstructions, piping must be supported. At
least one bracket must be used within 6" from the
top of the elbow and then every 24" (610mm) as
shown in FIGURE 36, to prevent any movement
in any direction. When exhaust and intake piping
must be run up an outside wall, the exhaust piping
must be terminated with pipe sized per table 9.The
intake piping may be equipped with a 90° elbow
turndown. Using turndown will add 5 feet (1.5m) to
the equivalent length of the pipe.
8 - Based on the recommendation of the manufacturer,
a multiple-furnace installation may use a group
of up to four terminations assembled together
horizontally, as shown in FIGURE 34.
