Figure 13 - Two Pipe Sidewall Venting and Sidewall Venting with
Optional Kit (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
pitched a minimum of 1/4" 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 of 4 foot intervals on the vent pipe. Venting must be
readily accessible for visual inspection from the first three feet
from the boiler.
