Horizontal Termination Configurations
Figures 14 through 18 show different configura-
tions and alternatives for venting with horizontal
termination. Each figure includes a chart with
critical minimum and maximum dimensions which
MUST be met. IMPORTANT: Remember that a
horizontal run of venting must have a 1/4" rise for
every 12" of run toward the termination.
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.
