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.

Note: See Page 23 for exterior wall recess allowances
with horizontal termination.
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).
• For projections greater than 2-1/2" (64
mm), see Figure 21-1.
• For additional vent location restrictions, see
Page 22.
NOTICE
Our horizontal terminations meet or exceed industry standards and are designed to per-
form in a wide range of weather conditions.
NEVER place a horizontal termination where water from eaves or roof lines may create a
heavy flow of cascading water onto the termination cap. If the cap must be placed where
the possibility of cascading water exists, it is the responsibility of the builder to direct the
water away from the termination cap using gutters or other means.
Carefully follow the installation instructions for the termination, including the use of sili-
cone caulking where required.
