NOTE: These drawings are meant to demonstrate system venting only.
The installer is responsible for all equipment and detailing required by
local codes.
All vent pipes must be glued, properly supported, and the exhaust
pitched a minimum of 1/4” per foot back to the heater to allow
drainage of condensate. When placing support brackets on vent
piping, the rst bracket must be within 1 foot of the water heater
and the balance of 4 foot intervals on the vent pipe. Venting must be
readily accessible for visual inspection from the rst three feet from
the heater.
NOTE: When installing two pipe sidewall venting, terminate 2”
exhaust vent pipe with a 90
o
elbow, and 3” exhaust vent pipe
with a 45
o
elbow. Failure to do so will result in improper appliance
operation.
