NOTE
Two 45°° elbows (P/N 945) may be used in place of one 90°° elbow (P/N 990).
WARNING
Any horizontal run must have a 1/4” rise for every one (1) foot of run towards the vent termination. Never
allow the vent to run downward. This could cause high temperatures and may present a fire hazard.
Figure 12: Installing Pipe Supports
WARNING
Always maintain minimum clearances around vent systems. The minimum clearances to combustibles for
vent pipe require 3 inches at the top and 1 inch at the sides and bottom for horizontal sections of the vent
system. For wall or ceiling firestops and vertical sections of vent pipe a 1-inch minimum clearance all around
the pipe must be maintained. Do not pack the open air spaces with insulation or other materials. This could
cause high temperatures and may present a fire hazard.
5. A wall or ceiling firestop (P/N 963) MUST BE installed if the vent passes through a wall or ceiling.
For wall
• Cut a 10-inch X 10-inch hole through the interior or exterior wall. The center of the hole is the
centerline of the horizontal pipe. Refer to the figure below.
• Position the firestop on the hole previously cut and secure with screws or nails.
• Run vent through firestop.
