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 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.
NOTES:
A. For every 1” of overhang, the exhaust vent must be located 1”
vertical below overhang (overhang means top of building structure
and not two adjacent walls [corner of building]).
B. Typical installations require 12” minimum separation between
bottom of exhaust outlet and top of air intake.
C. Maintain 12” minimum clearance above highest anticipated snow
level or grade (whichever is greater).
D. Minimum 12” between vents when installing multiple vents.
E. 12” minimum beyond air intake.
