Figure 20 – Venting with Optional Kits (NOT INCLUDED WITH THE BOILER) NOTE: These drawings are 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 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.
