12 - INSTALLATION - CATEGORY IV: Vent and combustion air
b. Apply a liberal even coat of
VITON-BASED RTV high
temperature silicone (or
equivalent) to the adapter “R”
approximately 2” beyond the
socket depth.
c. While the VITON-BASED RTV
high temperature silicone is
still wet, insert the adapter “R”
into the heater connection “B”.
NOTICE!
If voids are present,
sufficient VITON-BASED RTV
was not applied and joint could be
defective.
d. Tight the clamp to mechanically
secure the joint
2. Insert vent pipe “G”, into adapter
“R”, following instruction of
stainless steel pipe manufacturer.
12.7.2 - Stainless steel
vent connection
Vent connection (Figure
12-11 item “B”)
is used to
provide a passageway for conveying
combustion gases to the outside. Vent
piping must be supported per the
National Building Code, Section 305,
Table 305.4 or as local codes dictate.
To connect a stainless steel pipe
to the vent connection proceed as
follows while referring to Figure 12-11:
1. Dry fit adapter “R” to ensure proper
fit up before assembling adapter
to the heater connection “B”. The
adapter “R” should go completely
into the heater adapter to ensure
proper sealing after sealant is
applied.
a. Handle adapters “R” and heater
connection “B” carefully to prevent
contamination of surfaces.
