WIRING DIAGRAM—ALL WGFM195 EXCEPT WGFM195090S5C
Check codes for proper wiring and circuit protection before installation.
NOTES:
1. Set heat anticipator on room thermostat at 0.7 amps.
2. Manufacturer’s specified replacement parts must be used
when servicing.
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 105ºC. Use copper conductors
only.
4. If heating and cooling blower speeds are not the same,
discard jumper before connecting blower leads. Unused
blower leads must be placed on “PARK” terminals of
integrated control or taped.
5. Furnace must be permanently grounded and conform to NEC
and local codes.
6. To recall the last 5 faults, most recent to least recent, depress
switch for more than 2 seconds in standby (no thermostat
inputs).
