The vent must be installed to prevent the potential accumulation of stack
condensate in the horizontal run of vent pipe. Therefore, it is recommended that:
1. The vent shall be installed with a slight downward slope of not more than 1/4"
per foot of horizontal run to the vent termination.
2. The vent must be insulated through the length of the horizontal run.
Note: For installations in cold/freezing climates, it is recommended that:
1. The vent shall be installed with a slight upward slope of not more than 1/4" per
foot of horizontal run to the vent termination. In this case, an approved
Condensate trap must be installed per applicable codes.
2. The vent must be insulated through the length of horizontal run.
The stack vent cap MUST be mounted on the exterior of the building. The stack vent
cap cannot be installed in a well or below grade. The stack vent cap must be
installed at least two feet above ground level and above normal snow levels.
