GENERAL NOTE: All vent pipes must be glued, properly supported and the exhaust must be pitched a
minimum of a ¼" per foot back to the heater (to allow 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 boiler venting must be readily
accessible for visual inspection for the first three feet from the boiler.
