Assembly Instructions - BVETTO B-Vent Series
9.
The high temp lintel, as supplied, is forty five inches (45”)
long and fits the BVETTO models 36 & 46. Field cut the high
temp lintel equally at the perforated lines as required for the
36” unit. This will ensure the limit switch and micro-switch
are located in the proper position on the lintel.
Connect the two (2) leads from the high temperature
wires to the thermocouple junction block (see diagram,
page 29).
Measure and locate the centerline of the fireplace open-
ing. Align notch at the front of the lintel to the centerline of
the fireplace. Install lintel using 1 1/2” masonry screws.
NOTE:
The limit switch and microswitch are already sup-
plied and mounted in the BVETTO high temp lintel compo-
nent. Connect the two high temperature wires (coming out
the top of the BVETTO left hand firebox side wall) to the two
high temperature wires that are attached to the limit switch
with ceramic wire nuts.
The small tab near damper lever should be bent upward
to stand vertical. This protects wires passing through the
harness.
WARNING:
Do not bypass the high temperature limit
switch. Install downdraft diverter at the top plate.

Orient assembly such that the wire cable is toward the
front of the fireplace opening.
Loosen screws on the cable clamp and loop between
the two washers at the end of the handle asembly.
NOTE:
Wire clamp should be approximately 4” from the
washers. Tighten lock nuts on the handle if necessary. Pull
cable to close the damper and adjust the length of wire
cable by swinging the handle between open and close po-
sitions. When in the open position, the damper should be
rotated a full 90 degrees from the closed position. Retighten
screws on the cable clamp and remove excess cable.
The high temp lintel fits horizontally up toward the bot-
tom of the smoke dome. The adjoining short leg of the high
temp lintel fits up against the bottom of the smoke dome
component. (Figure 19)
The high temp lintel has 4 pilot holes for the screw
placement. Attach the high temp lintel flush against the
front face of the smoke dome with 4 mounting screws driv-
en into the face of the BVETTO smoke dome.
Any excess wire draped between the high temp lintel
and the left hand firebox sidewall should be neatly tucked
into the hollow core of the left hand sidewall. Excess wire
should not be visible below the canopy bottom.
NOTE:
The 2 high temperature wires inside of the BVETTO
firebox will connect to the appropriate contacts found on
the gas log assembly during the installation of the gas log
set.
