MINIMUM RISE HORIZONTAL TERMINATION
The FV46 Fireplace must be installed by a qualified Mendota approved serviceperson.
18” maximum horizontal run allowed with the minimum 12” vertical rise.
With the minimum 12” vertical pipe and a 90-degree elbow connected to the
fireplace, the horizontal centerline of the 90
º
elbow will be 57 ½” inches up from
the floor level of this Fireplace.
See, MASTER VENTING CHART and Figures, below.
Use "fixed" pipe sections in place of adjustable pipe sections wherever possible.
Always maintain 1" clearance from vent pipe sides and bottom to combustibles,
3" clearance on top of pipe on horizontal runs and on top of horizontal discharge
elbows. Do not fill air spaces with insulation or other material.
1. Position fireplace in desired location. See guidelines on proper vent cap
placement on the exterior of home. Check to determine if wall studs are in
the way when venting system is attached. If this is the case, you may want to
adjust the fireplace location or modify the exterior wall framing to allow the
vent system to penetrate the wall.
2. Measure from the floor level of the fireplace up 57 1/2” inches [add ¼” rise
for every foot of horizontal run] and mark wall directly at the center of where
the vent pipe will penetrate the exterior wall.
3. Cut and frame a 10-3/4" wide x 10-3/4" high opening in the wall. The hole
must be positioned so the vent system will run level or have a ¼" rise per foot of run AND be perpendicular to the wall. The
height of the opening must be located to meet all local and national building codes. Do not allow the termination to be easily
blocked or obstructed. If wall being penetrated is non-combustible material, i.e. masonry block, brick, etc., a 9-inch diameter
hole is acceptable.
4. A wall thimble must always be used when penetrating combustible wall materials. Wall thimbles reduce required clearances
to combustible materials.
5. From the exterior of the home, slide the horizontal vent cap over the end of the horizontal pipe and tightly secure the cap to the
wall with screws. Seal with a high-quality caulking between vent cap outer edges and wall.
NOTE: Combustible wall thickness must be 4" to 8" maximum
NOTE: Vent Cap should not be recessed into wall or siding.
VERTICAL RISE HORIZONTAL TERMINATION
If the total length of the vertical sections connected directly to the starter adapter on this fireplace is between 4 feet and 30 feet,
you are allowed a maximum 20 feet horizontal run. This fireplace provides a 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. No reduction in horizontal run is required for the use of the elbows. See Master
Venting Chart.
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.

1. Position fireplace in desired location. See
3.2.19.5 Exterior Vent Locations and Restrictions
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
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 (See
3.2.19.5 Exterior Vent Locations and Restrictions
). Be sure all
vent components are properly twist locked and leak-proof.
