Termination Kit
All horizontal terminations
may be located as close
as 6” (152mm) to any
(non-combustible and
combustible) exterior
sidewall. This distance
may be decreased to
2” (51mm) for non-
combustible exterior
sidewalls only, if the
SV4.5HT-2 termination
is used.
Horizontal Vent Termination Clearances
The horizontal vent termination must have a
minimum of 3" (76 mm) clearance to any over-
head combustible projection of 2-1/2" (64 mm)
or less. See
Figure 5.
For projections exceed-
ing 2-1/2" (64 mm), see
Figure 5
. All horizontal
terminations may be located as close as 6"
(152mm) to any (non-combustible and com-
bustible) exterior sidewall. This distance may
be decreased to 2" (51mm) for non-combus-
tible exterior sidewalls only, if the SV4.5HT-2
termination is used. For additional vent location
restrictions refer to
