Horizontal Termination Configurations
Figures 14 through 18 show different configurations 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 minimum 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.
