Intertek ACVC96 Service Instructions Manual page 25

INSTALLATION CONSIDERATIONS
1) Maximum allowable limits listed on individual lengths for inlet and flue
and NOT a combination.
2) Minimum requirement for each vent pipe is five (5) feet in length and
one elbow/tee.
3) Tee used in the vent/flue termination must be included when deter-
mining the number of elbows in the piping system.
4) 2 1/2" or 3" diameter pipe can be used in place of 2" diameter pipe.
5) Increased Clearance Configurations using (2) 45 deg. Long Sweep
elbows should be considered equivalent to one 90 deg. elbow.
6) One 90° elbow should be secured to the combustion air intake con-
nection.
Vent/Flue and Combustion Air Pipe Terminations
V /F C
ENT LUE AND OMBUSTION
The vent/flue and combustion air pipes may terminate verti-
cally, as through a roof, or horizontally, as through an out-
side wall.
Vertical pipe terminations should be as shown in the follow-
ing figure. Refer to Section IX, Vent/Flue Pipe and Com-
bustion Pipe - Termination Locations for details concerning
location restrictions. The penetrations through the roof must
be sealed tight with proper flashing such as is used with a
plastic plumbing vent.
Horizontal terminations should be as shown in the following
figure. Refer to Vent/Flue Pipe and Combustion Pipe - Ter-
mination Location section in this manual or the installation
instructions for location restrictions. A 2 3/8" diameter wall
penetration is required for 2" diameter pipe while a 3 1/2"
diameter hole is required for 3" diameter pipe. To secure the
pipe passing through the wall and prohibit damage to piping
connections, a coupling should be installed on either side of
the wall and solvent cemented to a pipe connecting the two
couplings. The pipe length should be the wall thickness
plus the depth of the socket fittings to be installed on the
inside and outside of the wall. The wall penetration should
be sealed with silicone caulking material.
