Horizontal Termination Configurations
Figures 14 through 18 show different con
-
figurations and alternatives for venting with
horizontal termination. Each figure includes
a chart with critical minimum and maximum
dimensions which MUST be met.
IMPORTANT
: If using a venting configuration
of only horizontal venting with no vertical run,
a 1/4" rise for every 12" of run toward the
termination is required.
NOTICE: Do not seal termination
cap to vent pipe. Cap must be
removable for vent inspection
and maintenance.
WARNING: Never run vent
downward as this may cause
excessive temperatures which
could cause a fire. Operation of
improperly installed and main
-
tained venting system could
result in serious injury, property
damage or loss of life.
