FIRE OR ELECTRICAL SHOCK HAZARD
Failure to follow this warning could result in personal
injury, death, or property damage.
If field-supplied manual disconnect switch is to be
mounted on furnace casing side, select a location where
a drill or fastener cannot damage electrical or gas
components.
The J-Box is used when field line voltage electrical connections
are made to the furnace wiring harness inside the furnace
casing. The J-Box is not required if a field-supplied electrical
box is attached to the outside of the furnace casing and the box
is grounded to the green ground wire of the main wiring
harness and the earth ground of the field electrical supply.
The J-Box cover, mounting bracket and screws are shipped in
the loose parts bag included with the furnace. The J-Box can
be mounted on the left or right side of the casing, as viewed
from the upflow position. (See Figure 36)
