VERTICAL TERMINATION SYSTEM
FIGURES AND TABLES
Secure Vent™ rigid vent pipe and termination
components are shown in the figures.
Note: Two 45-degree elbows may be used
in place of one 90-degree elbow. If using
45-degree elbows, follow the same rise-to-
run ratios as shown for 90-degree elbows.

NOTICE:
 Secure Vent Vertical Firestop/Spacer
(SV8BF) must be used anywhere vent
pipe passes through a combustible
floor or ceiling. Secure Vent Horizontal
Firestop/Spacer (SV8HF4) must be used
anywhere vent pipe passes through a
combustible wall.
 It is important to install horizontal runs
on a steady, (i.e., no “dips”), slightly
positive incline of approximately 1/4
inch rise-per-foot (20 millimeters
rise-per-meter) horizontal, in a direc-
tion away from the fireplace. (Slightly
smaller rise-per-foot run ratios are
acceptable.) Use a carpenter’s level to
measure from a constant surface, and
adjust support straps as necessary.
