Do not run vent connector along outside
wall.
The diameter of the vent pipe must be
identical to the diameter of the draft
hood chimney connection.
Installation
1.
Install the venting so as to achieve
the shortest possible way with
minimum elbows. If necessary,
rearrange existing water piping to
achieve closest chimney connection.
2.
Horizontal runs must be supported by
appropriate means to prevent
sagging. Avoid long horizontal runs of
vent pipe. Horizontal runs should
have no less than ¼” rise per ft.
from the boiler to the vent terminal.
Metal strapping must be used to
support horizontal runs every 4 ft. /
1.2 m.
3.
Fasten sheet metal vent pipe adaptor
supplied with boiler (if applicable) to
the draft hood flue collar. Use high
temperature silicone to seal between
sheet metal adaptor and boiler draft
hood connection. Drill pilot holes with
11/64” cobalt HSS drill bit and fasten
using three equally spaced screws.
Vent pipe adaptors are shipped in the
Installation Fitting Package.
4.
Connect vent pipe adaptor with
chimney via a field supplied, slightly
inclined intermediate section of
venting. Draft hood flue pipe

5.
Drill a ½” opening
on the side of
the vent pipe approximately two
times the vent pipe diameter away
from the flue gas collar of the boiler
for flue gas analysis equipment.
6.
It is recommended to seal all flue
pipe joints.
7.
Ensure any non-insulated vent pipe is
insulated to reduce cooling of flue
gas.

IMPORTANT
IMPORTANT
Failure to securely fasten all vent
connections, including vent pipe
adaptor to boiler, can cause flue
gases to enter living space. Flue
gases leaking into living space can
cause carbon monoxide poisoning
which may result in severe personal
injury or loss of life.
