Horizontal Termination Systems – Vent Configurations
10) For horizontal terminations, install at least one 12“vertical pipe section on the anchor plate before any
elbow installation
NOTE: Two 45° elbows may be combined to achieve 90° offset.
NOTE: A minimum of 48” length of chimney pipe is required from the last elbow for horizontal
termination.
11) If the installation is a continuous horizontal run that passes through any combustible wall, a wall thimble
is to be utilized at each wall penetration. Continue the installation of the chimney by installing sections of
B-vent pipe to the location of termination.
12) If the installation must pass through an attic, floor, or ceiling the B-vent Firestop shall be utilized. To pass
the pipe through the floor/ ceiling, begin by cutting a hole in the floor/ ceiling that is 2 inches larger than
the outside diameter (OD) of the B-vent pipe’s outer casing. The B-vent Firestop is installed at the
underside of this penetration. The B-Vent pipe is to be centered in the firestop’s opening. When
installed, check to make sure the one-inch (25.4 mm) clearance to combustible has been maintained.
13) The horizontal vent system will be terminated with a mechanical draft system. Installation instruction for
the mechanical draft system begins on page 32.
IMPORTANT: Framing and sheathing at horizontal termination shall require non-combustible material
within the 18” clearance zone as measured from outer diameter of MFD collar.
