Figure 14 - 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.
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.
