-
ration for venting with horizontal termination
with a chart of critical minimum and maximum

zontal venting with no vertical run, a ¼'' rise
for every 12'' of run toward the termination
is required.

cap to vent pipe. Cap must be
removable for vent inspection
and maintenance.

excessive temperatures which
could cause a fire. Operation of
