IMPORTANT
The exhaust vent/air intake system must terminate so
that proper clearances are maintained as cited in local
codes or the latest edition of the "Natural Gas and
Propane Installation Code" CAN/CSA-B149.1 (Canada),
or the "National Fuel Gas Code" ANSI Z223.1 (NFPA
54) (U.S.A.).
IMPORTANT
For PP systems, all exhaust vent and air intake piping
and elbows exposed outside, must be UV resistant
polypropylene (supplied by the vent manufacturer).
WARNING
Vent termination must be at least 12 in. (305 mm)
above the anticipated snow level (consult your local
building authorities or local weather office). Locate
vent termination in such a way that it cannot be
blocked by snow.
