KN INSTALLATION INSTRUCTIONS FOR VENT AND AIR PIPING
Vent and air piped through a side wall
(concentric termination)
6
7 — Sidewall concentric vent-air termination
❑
See Table 6 for part numbers of the sidewall termination components required for
EZ-Seal vent pipe installations. Th e vent termination must be constructed using
the stainless steel vent materials listed in Table 5 to ensure the confi guration is
correct. DO NOT terminate the air piping with any other method.
A.
Wall plates (2 required)
— Use only the plates listed in Table 6. Follow the
vent manufacturer’s instruction to prepare the wall and mount the plates.
Th e air space provided by the design of the SC type vent allows the concentric
vent/air pipe to be run directly through combustible or noncombustible
walls. No thimble is needed unless specifi ed by applicable codes.
Aft er the pipe (item
B
) is inserted and placed, follow the vent manufacturer’s
instructions to insert self-tapping screws through the four tabs in each of the
wall plates into the holes in the pipe. Th is secures the pipe in place.
Follow the vent pipe manufacturer’s instructions for sealing around the plates
and the pipe.
B. Length of concentric vent pipe
— Use a 1-foot length of vent pipe as
listed in Table 6 unless the wall penetration quires a longer length. If a longer
length is required, use a length of Heat-Fab type SC vent long enough for the
application.
C. Air intake tee
— Th e air intake tee provides a connection for the air piping to
feed air through the outer plenum of the type SC vent and fi tt ings. Secure the
vent pipe to the end following the vent pipe manufacturer’s instructions for
assembling joints. Att ach the air pipe to the air connection using silicone RTV
to seal the joint.
D. Termination
adapter
— Assembly the termination adapter to the type SC
pipe, following the vent pipe manufacturer’s instructions for making the joint.
E. Termination
screen
— Apply a bead of silicone RTV to the male end of the
screen fi tt ing before inserting into the adpatper. Bend the adpater tabs over the
end of the screen fi tt ing.
❑
Termination locations
— Place all terminations so they meet the clearances
shown in Figure 21.
Multiple boiler installations
❑
Install multiple vent/air terminations through the side wall following all guidelines
for single-vent/air installations.
❑
Install the terminations so they are no closer than 2 feet
(0.6 m)
on horizontal
centers and 4 feet on vertical centers (Figure 22).
❑
All terminations must comply with minimum clearances shown in Figure 21.
