Take extra precaution to adequately support the weight of vent
pipes terminating through the roof. Failure to properly support roof
terminated piping could result in property damage, serious injury,
or death.

Figure 18 - 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
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 rst 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 rst three feet from the
boiler.
