Vertical Rise Horizontal Termination
The minimum vertical section required to be connected directly to the starter adapter on this fireplace is 4’
when used with a maximum horizontal run of 32’. If the total length of the vertical sections connected
directly to the starter adapter on this fireplace is between 4’ and 12’, you are allowed a maximum 32’
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 44’.
Note: The horizontal run of vent pipe must 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. Be sure 1000°F sealant is used in the inner pipe
joints of all pipe sections manufactured by Simpson DuraVent.
3. Cut and frame a 10 ½” wide x 10 ½” high opening in the outside wall openings and 10” x 10” 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 require 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 3" above horizontal runs.
5. A wall thimble must always be used when penetrating combustible wall materials.
Note: Combustible wall thickness must be 4" to 8" maximum.
Note: Do not separate telescoping section. They be must be used as complete assemblies.
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 around the outer
perimeter of the vent cap.
Note: Vent cap should not be recessed into wall or siding.
