WARNING
In 90% furnace upright upflow installations, the drain
trap must be mounted on the opposite side of the unit
from the junction box. This will reduce the risk of wa-
ter reaching the junction box in the event of a blocked
drain condition.
Connect hot, neutral, and ground wires as shown in the
wiring diagram located on the unit's blower door. Line po-
larity must be observed when making field connections. Line
voltage connections can be made through either the right
or left side panel.
The 80% and 90% furnaces are shipped configured for a
left side electrical connection with the junction box located
inside the burner compartment on 80% furnaces and in-
side the blower compartment on 90% furnaces. To make
electrical connections through the opposite side of the fur-
nace, the junction box must be relocated to the other side
of the burner compartment on 80% furnaces and to the
other side of the blower compartment on 90% furnaces prior
to making electrical connections, refer to the following fig-
ures.
CAUTION
Edges of sheet metal holes may be sharp. Use gloves
as a precaution when removing hole plugs.
