tions and alternatives for venting with horizontal
termination. Each gure includes a chart with
critical minimum and maximum dimensions
which MUST be met. IMPORTANT: If using a
venting conguration of only horizontal venting
with no vertical run, a 1/4" rise for every 12" of
run toward 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 re. Operation of
improperly installed and main-
tained venting system could
result in serious injury, property
damage or loss of life.
