NOTES:

(1) Make field power supply connections to black and white wires capped

with orange wire nuts.

(2) WARNING --- Unit must be grounded. Wiring must conform to N.E.C.

and local codes.

(3) If any of the original wire, as supplied with the furnace, must be

replaced, it must be replaced with wiring material having a temperature

rating of at least 185 C and be a minimum of 16 GA. AWG copper

strand wire.

(4) Connect required motor lead to heat terminal on circuit board to deliver

a temperature rise within the range specified on the rating plate.

Connect unused motor leads to the "M1 & M2" terminals.
