Minimum Rise Horizontal Termination
The minimum vertical section required to be connected directly to the starter adapter on this fireplace is 12”. With a 12”
vertical starter section, a 6” horizontal run to a horizontal vent cap is allowed. If the total length of the vertical sections
connected directly to the starter adapter on this fireplace is between 4’ and 25 ’ , you are allowed a maximum 1 2’ horizontal run.
This fireplace provides a maximum flexibility in the use of 90
°
elbows when more than 4’ of vertical starter section is connected
to the starter collar. If 4’ or more vertical section is connected to the starter collar, you may use three 90° elbows for horizontal
terminations. For other venting configurations within these maximum limits, see Master Venting Chart.
Combined total length of all pipe sections in the vent system should be less than 4 4’ .
NOTE: The horizontal run of vent pipe must be level or have a ¼" rise for every 1' of run toward the
termination. Never allow the vent to run downward. This will cause high temperatures and the possibility
of a fire.
Follow these steps to install venting:
1. Position fireplace in desired location. Check to determine if wall studs are in the way when vent system is attached. If this is the
case you may want to adjust the fireplace location.
2. Locate where vent pipe will pass through any ceilings and will penetrate the outside wall. Since vent pipe sections "overlap,"
we suggest pre-assembling and measuring the total vent pipe run so you can more accurately locate the point where the vent
pipe will penetrate the outside wall. Be sure all vent components are properly twist locked and leak-proof.
3. Cut and frame a 9 ” wide x 10 ” high opening in the outside wall openings and 9 ” x 9 ” opening in ceiling openings. The outside
wall hole must be positioned so the vent system will have a ¼" rise per foot on horizontal runs 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. The horizontal pipe must end flush with the exterior wall of the home. Horizontal pipe will requ ire a proper support every 3’ of
vent pipe. There must be a minimum of 1" clearance to combustibles from all vent pieces on the sides and bottom and 2"
above horizontal runs.
5. A wall thimble must always be used when penetrating combustible wall materials.
6. Note: Combustible wall
thickness must be 4" to 8"
maximum.
Note: Do not separate
telescoping section. They
be must be used as
complete assemblies.
7. 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 around the outer
perimeter of the vent cap.
Note: Vent cap shall not be
recessed into wall or
siding.
