I. DIAGRAMS FOR SIDEWALL VENTING
**Important Note: All vent pipes must be
glued, properly supported, and the exhaust
must be pitched a minimum of a 1/4" per
foot back to the heater (to allow for
drainage of condensate).
NOTE: When placing support brackets on vent piping, the first bracket must be within 1 foot of the
appliance and the balance at 4 foot invervals on the vent pipe. The heater venting must be readily
accessible for visual inspection for the first three feet from the heater.
