Horizontal Termination Congurations
Figures 14 through 18 show different congura-
tions and alternatives for venting with horizontal
termination. Each figure includes a ch art with
critical minimum and maximum dimensions which
MUST be met. IMPORTANT: If using a venting
conguration 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 re. Operation of improperly installed and main-tained venting system could result in serious injury, property damage or loss of life.
