WARNING!!!
Use only the
materials, vent systems, and
terminations listed in Figures
11-7 and 11-8. DO NOT mix vent
systems of different types or
manufacturers, unless listed in
this manual. Failure to comply
could result in severe personal
injury, death, or substantial
property damage.
WARNING!!!
This
appliance requires a special
venting system. The field
provided vent appliance
adapter (Figure 11-11, item
"B") must be connected to the
appliance following Section
11.7.2. Failure to follow this
warning could result in fire,
personal injury, or death.
WARNING!!!
Improper
installation of Stainless steel
systems may result in injury or
death.
WARNING!!!
Use only
water-based lubricants on joints.
Never use hydrocarbons-based
lubricants because they would
destroy gaskets. Failure to
follow this warning could result
in excessive levels of carbon
monoxide, which can result
in severe personal injury or
death!
NOTICE! Installation must comply
with local requirements and with the
National Fuel Gas Code, ANSI Z223.1
for U.S. installations or CSA B149.1 for
Canadian installations.
NOTICE! For installation in Canada,
vent pipe system must be certified to
ULC-S636 (see Figure 11-7).
NOTICE! All vent pipes connections
must be secured following manufacturer
instruction, properly supported, and the
exhaust must be pitched a minimum of
a 1/4 inch per foot back to the appliance
(to allow drainage of condensate).
NOTICE! Installation of a stainless
steel vent system should adhere to
the stainless steel vent manufacturer's
installation instructions supplied with
the vent system.
NOTICE! The installer must use a
specific vent starter adapter at the
flue collar connection, supplied by the
vent manufacturer to adapt to its vent
system. See Figure 11-8 for approved

11.7.1 - Stainless steel air
intake connection
Combustion Air Intake
connection (see Figure 11-11
Item "M").
This connection is used to provide
combustion air directly to the
appliance from outdoors. Combustion
air piping must be supported per
guidelines listed in the National
Mechanical Code, Section 305, Table
305.4 or as local codes dictate.
To connect a stainless steel pipe to
the air intake connection proceed as
follows while referring to Figure 11-11:
1.- Dry fit adapter "R" and appliance
connection "P" to ensure proper fit
up before assembling the adapter
to the appliance. The adapter
"R" should go completely into the
appliance connection to ensure
proper sealing after sealant is
applied.
a. Handle adapters "R" and
appliance adapter "P" carefully
to prevent contamination of
surfaces;
b. Apply a liberal even coat of
MOMENTIVE - RTV 106
high temperature silicone (or
equivalent) to the adapter "R"
approximately 2" beyond the
socket depth;
c. While the MOMENTIVE - RTV
106 high temperature silicone is
still wet, insert the adapter "R"
into the applianceconnection "P".
NOTICE! If voids are present,
sufficient MOMENTIVE - RTV 106
was not applied and joint could be
defective;
d. Tight the clamp to mechanically
secure the joint.
2.- Insert air intake pipe "N", into
adapter "R", following instruction of
stainless steel pipe manufacturer.
