NOTE
: Do not allow insulation or other materials to
accumulate inside the pipe assembly when installing it
through the hole. Disassemble loose pipe fittings. Clean
and cement using the same procedures as used for
system piping.

Two pipe termination
Maintain the required distance between vents or pairs
of vents. Cut the required number of holes in the roof
or sidewall for vent and combustion air pipes. Sidewall
holes for two pipes vent terminations should be side-by-
side, allowing space between the pipes for the elbows to
fit on the pipes. Holes in the roof for two pipe terminations
should be spaced no more than 18” (457 mm) apart.
Termination elbows will be installed after the vent and
combustion air pipe are installed.
Combustion air intake can be snorkeled to acheive 12"
min distance from expected level of snow and/or ground.
