8.22.4 — IFGR Lubrication
Motors should be lightly lubricated at startup.
1. Disconnect and lock out electrical power to the boiler.
2. Wipe clean all grease fittings (fill and drain fittings).
3. Remove the fill and drain plugs from the motor end cap.
4. Free the drain hole of any hard grease (if necessary, use a piece of wire).
5. Add grease using a low-pressure grease gun.
6. With the fill and drain plugs still removed, apply electric power to the boiler, start the motor, and let it run for
approximately 30 minutes.
7. Turn the boiler off.
8. Disconnect and lock out electrical power to the boiler.
9. Wipe excess grease from the motor, and install the fill and drain plugs. The motor is ready for operation.
10. Reconnect electrical power.
8.23 — Oil Heater: Electric, Steam, Hot Water
An annual maintenance of the heaters consists primarily of removing the heating element from the shell and scrap-
ing any accumulation of carbonized oil or sludge deposits that may have collected on the heat exchanging surfaces.
Before breaking any of the electrical connections to the electric heating elements, mark all wires and terminals to
assure rapid and correct replacement of wires.
Finish the cleaning process with a cleaning solvent to cut all hardened deposits from the heater element. Because of
the insulating effect of carbon and sludge, periodic cleaning is necessary to prevent overheating of the elements. If
operation of the heater becomes sluggish, examine the elements at once and clean as required.
Inspect the shell or tank each time the heater is removed. Flush all accumulated sludge and sediment from the tank
before reinstalling the heater.
Disconnect and lock out electrical power to the boiler before lubricating the fan motor. Failure to follow these instruc-
tions could result in serious injury or death.
NOTE: The amount and type of grease is very important. Only enough grease should be added to replace the grease
used by the bearing. Either too much or too little grease can be harmful. The grease cavity should be filled 1/3 to 1/2
full, using Chevron SRI 2 grease or equivalent. Shell Dolium R is a suitable substitute lubricant.
Disconnect and lock out electrical power to the boiler before lubricating the fan motor. Failure to follow these instruc-
tions could result in serious injury or death.
