VERTICAL RISE HORIZONTAL TERMINATION
The minimum vertical section required to be connected directly to the starter adapter on this fireplace is 48 inches when
used with a maximum horizontal run of 20 ft. If the total length of the vertical sections connected directly to the starter
adapter on this fireplace is between 4 feet and 41 feet, you are allowed a maximum 20 feet horizontal run. This fireplace
provides a maximum flexibility in the use of 90
0
elbows when more than 4 feet of vertical starter section is connected to
the starter collar. If 4 feet or more vertical section is connected to the starter collar, you may use three 90 degree elbows
and 20 feet of horizontal pipe sections. No reduction in horizontal run is required for the use of the elbows. For other vent-
ing configurations within these maximum limits, see Master Flue Venting Requirements Chart, Zone A and Zone B.
Combined total length of all pipe sections (include restriction of elbows) in the vent system shall be less than 64 feet.
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.
This FV46 Fireplace must be installed by a qualified Mendota service person
1. Position fireplace in desired location. See Exterior Vent Locations and Restrictions section for guidelines on proper
vent cap placement on exterior of home. Check to determine if wall studs are in the way when vent system is at-
tached. 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 (See Exterior Vent Locations and Restrictions section). Be
sure all vent components are properly twist locked and leak-proof. Be sure 1000º sealant is used in the inner pipe
joints of all pipe sections manufactured by Simpson DuraVent.
3. Cut and frame a 10-3/4” wide x 10-3/4”” 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 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 ter-
mination 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 2" ABOVE HORIZONTAL RUNS).
6. A wall thimble must always be used when penetrating combustible wall materials.
NOTE: Combustible wall thickness must be 4" to 8" maximum.
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.
NOTE: Venting terminal (Vent Cap) should not be recessed into wall
or siding.
NOTE: DO NOT SEPARATE TELESCOPING SECTIONS.
THEY MUST BE USED AS COMPLETE ASSEMBLIES.
