Note 1
REDUCE MAXIMUM VENT/AIR PIPE LENGTHS FOR ELBOWS
If the TOTAL number of elbows used in the vent and air piping and terminations is
more than two elbows in the vent
piping and one elbow
in the air piping,
REDUCE
the maximum lengths above by the following lengths for each additional
elbow (whether 45° or 90°).
6-inch vent/air piping — Reduce maximum allowable length by 15 feet for each additional elbow used.
8-inch vent/air piping — Reduce maximum allowable length by 7 feet for each additional elbow used.
NOTE
:
If the pipe manufacturer’s equivalent lengths for elbows is LONGER than the values listed above, use the
pipe manufacturer’s value for length reduction per elbow instead.
Boilers will
derate
as vent/air pipe length increases — see Figure 108, page 116 for derate amount vs piping length.
Note 2
Side air intake/through the roof vent
must use
Combustion Air Pressure Kit, see Figure 96, page 105 for Kit part number.
See Note 2.
