The FV46 Fireplace must be installed by a qualified Mendota approved serviceperson.
A Maximum Horizontal Run allowed is 18 inches if a 90-degree elbow is connected directly to this fireplace’s flue starter
collar.
When a 90-degree elbow is connected directly to this fire-
place, the horizontal centerline of the 90ºelbow will be 42-1/2”
inches up from the floor level of this Fireplace.
See MASTER FLUE VENTING REQUIREMENTS CHART.
Use "fixed" pipe sections in place of adjustable pipe section s
wherever possible. 1000º sealant must be used on ALL inner
pipe joints that do not have factory installed gasket material.
Always maintain 1" clearance from vent pipe sides and bottom
to combustibles, 2" 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 Exterior Vent
Locations and Restrictions section for guidelines on prop-
er vent cap placement on the exterior of home. Check to
determine if wall studs are in the way when venting sys-
tem 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 45-1/2”
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 locat-
ed 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 accepta-
ble.
4. Attach the 90-degree elbow to the fireplace starter adapter. Attach a horizontal section to the 90-degree elbow. Be
sure all vent component connections are in their fully twist-locked position and are leak-proof. Be sure 1000ºsealant
is used on the
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 caulk-
ing.
NOTE: Combustible wall thickness must be 4" to 8" maximum
NOTE: Vent Cap should not be recessed into wall or siding.
