3.
Cut and frame a 10-3/4” wide x 10-3/4”” high opening in the outside wall opening (for use with a mandatory wall thimble)
and 10 ½”x 10 ½” opening in ceiling openings (for use with a mandatory ceiling fire stop). The outside wall hole must be
positioned so the vent system will run level or have a ¼" on rise AND be perpendicular to the wall. The height of the
opening must be located to meet all building codes and not allow the termination to be easily blocked or obstructed. A
ceiling fire stop spacer is required at any floor (ceiling) opening.
4.
Connect vent pipe to the fireplace adapter on top of fireplace vent outlet.
5.
The horizontal pipe must end flush with the exterior wall of the home. Horizontal pipe will require a proper support every
3 ft. of vent pipe. THERE MUST BE A MINIMUM OF 1" CLEARANCE TO COMBUSTIBLES FROM ALL VENT PIECES ON THE
SIDES AND BOTTOM AND 3" ABOVE HORIZONTAL RUNS.
6.
A wall thimble must always be used when penetrating combustible wall materials. Wall thimbles reduce required
clearances to combustible materials.
NOTE:
Combustible wall thickness must be 4" to 8" maximum.
6.
From the exterior of the home, slide the horizontal vent cap over the end of the horizontal pipe and tightly secure the
vent cap to the wall with screws. Seal with high quality caulking.
NOTE:
Venting terminal (Vent Cap) should not be recessed into wall or siding.
