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 first 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 first three feet from
the heater.

These drawings are meant to demonstrate system venting only.
