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 6" (152 mm) clearance to any
overhead combustible projection less than
or equal to 2-1/2" (64 mm). See
Figure 38
.
• For projections greater than 2-1/2" (64
mm), see
Figure 38
.
• For additional vent location restrictions, see

NOTICE
Horizontal terminations have been designed to perform in a wide range of weather condi-
tions. Our terminations meet or exceed industry standards.
When selecting the locations of your horizontal terminations, do not place the termination
where water from eaves and adjoining rooflines may create a heavy flow of cascading
water onto the termination cap. If the cap must be placed where the possibility of cascad-
ing water exists, it is the responsibility of the builder to direct the water away from the
termination cap by using gutters or other means.
Take care to carefully follow the installation instructions for the termination, including the
use of silicone caulking where required.
