Note:
• Secure Vent
in the figures.
• 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
(SV8HTS4) for 90-degree elbows.

 Secure Vent
(SV8HTS4)
anywhere vent pipe passes through a combustible floor or ceiling.

Secure Vent Horizontal Firestop/Spacer (SV8HF4) must be used
(SV8HTS4)
anywhere vent pipe passes through a combustible wall.

 It is important to install horizontal runs on a steady, (i.e., no
(SV8L6)
"dips"), slightly positive incline of approximately 1/4" rise-per-
foot (20 millimeters rise-per-meter) horizontal, in a direction
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.
