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. Furnace must be permanently grounded and conform to NEC
and local codes.
5. To recall the last 6 faults, most recent to least recent, depress
