– Direct Vent, Roof and Sidewall Vent Terminations
All vent pipes must be glued, properly supported, and the exhaust must be pitched a minimum of ¼” per foot back to the boiler to allow
drainage of condensate. When placing support brackets on vent piping, the first bracket must be within 1 foot of the boiler and the
balance at 4 foot intervals on the vent pipe. Boiler venting must be readily accessible for visual inspection for the first three feet from the
boiler.
