NOTE

Two 45°° elbows (P/N 945) may be used in place of one 90°° elbow (P/N 990).

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.
