Inducer motor

1.With boiler power OFF, place a few drops of S.A.E. 20 motor oil in each of the two oil cups.

Use only S.A.E. 20 motor oil to lubricate the inducer motor. Do not use universal household oils. Motor could be damaged, resulting in possible severe property damage.

Part number 550-110-260/0200

Oiled bearing circulators

1.The circulator shipped with the CGs boiler is water-lubricated. No oiling is required.

2.Check other circulators in the system. Oil any circulators requiring oil, following circulator manufacturer’s instructions. Over-oiling will damage the circulator.
