3. Mount the sensor bracket using
two of the sheet metal screws
provided. Insert the screws
through the holes in the burner
support bracket and then into the
sensor bracket. Tighten with a
ratchet wrench and 1/4" socket.
See Figure 65.
Flame Sensor Mounting to Bracket
1. Insert the sensor (62-23543-01)
through the larger opening in the
bracket from the gas manifold
side.
2. Align the screw hole on the
sensor mount with the screw
hole in the bracket. Use a 1/4"
nut driver to anchor it with one of
the sheet metal screws provided.
3. The sensor rod should pass
diagonally in front of the burner,
as shown. See Figure 66.
IMPORTANT: DON'T ALLOW
THE SENSOR ROD TO TOUCH
ANY FURNACE COMPONENT.
4. Attach the remote sense
"NOTICE" label (92-22205-18)
in a prominent location on the
outside of the burner
compartment door.
5. Attach the sensor connection
label (90-23652-01) near the
existing wiring diagram on the
furnace.
