Figure 11 – This drawing is 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 must be pitched a minimum of ¼” 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 at 4 foot intervals on the vent pipe. Heater venting must be readily accessible for visual inspection for the first three feet
from the heater.
