Metal Canopy Installation:
The metal canopy, as supplied, is forty ve inches
(45”)longandtstheIBVmodels36&46.Fieldcutthemetal
canopy 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 replace
opening. Align notch at the front of the lintel to the centerline
ofthereplace.Installlintelusing11/2”masonryscrews.
Notes: The limit switch and microswitch are already supplied
and mounted in the IBV metal canopy component. Connect the
two high temperature wires (coming out the top of the IBV left
handreboxsidewall)tothetwohightemperaturewiresthat
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. (Figure 20)
Orient assembly such that the wire cable is toward the
frontofthereplaceopening.
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
positions. 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.
