The flue venting pipe is affixed to the adapter using high temperature RTV and then clamped
with a worm-driven Hose Clamp.
When using non-metallic (plastic) venting materials, use Schedule 40 or thicker Single-wall,
uninsulated pipes. When using non-metallic (plastic) vent systems for Canadian installations, per
CSA B149.1, use vent systems that are certified to the standard for Type BH Gas Venting
Systems, ULC-S636. The plastic components, primers and glues of the certified vent system must
be from a single system manufacturer and not mixed with other manufacturer
’s vent system parts.
The Inspection Port should be plugged with an appropriate plug (not included).

4.23 Combustion Air And Ventilation Openings
Provisions for combustion and ventiiation air must be made in accordance with
section 5.3
, Air
for
Combustion and Ventilation, of the National Flue Gas Code
,
ANSI Z223.1/NFPA 54.
, or
Sections 7.2, 7.3
or
7.4
of
CAN/CSA-B149.1-05
, installation codes, or appilcable provisions of

Insufficient Ventilations and Combustion Air
BOILER DAMAGE AND OPERATIONAL FAILURES may occur due to insufficient or improper
openings for combustion air and/or ventilation of the boiler room.
Provisions for combustion air and ventilation are always required, regardless of whether taken
from the outside (sealed combustion) or inside (room air used as combustion air).
Insufficient ventilation of the boiler room can lead to high air temperatures. This can result in
boiler damage. Note the following:
•
Make sure that intake and exhaust openings are sufficiently sized, and no reduction or
closure of any openings takes place.
•
When a combustion air or ventilation problem is not resolved, do not operate the boiler.
•
Please note these restrictions and its dangers to the operator of the boiler.
When one expects contaminated combustion air (near swimming pools, chemical cleaning
operations, hair salons, etc.), sealed combustion operation is recommended.
