Utica Gas-fired Boiler manual General Instructions, Do Not Over Oil

GENERAL INSTRUCTIONS

Before seasonal start-up, have a competent service agency check the boiler for soot and scale in the flues, clean the burners and check the gas input rate to maintain high operating efficiency.

CAUTION:

Label all wires prior to disconnection when servicing controls.

Wiring errors can cause improper and dangerous operation.

Verify proper operation after service.

The service agency or owner should make certain the system is filled with water to minimum pressure and open air vents, if used, to expel any air that may have accumulated in the system. Check the entire piping system and if any leaks appear, have them repaired.

Many circulators like the one pictured in figure 17 below, require periodic servicing. The motor usually has openings at each end to lubricate the bearings. Put about one half teaspoon of SAE 20 or 30 non-detergent motor oil in each opening twice a year.

CAUTION:

DO NOT OVER OIL.

Many circulators have an oil opening for the shaft bearing. This should be oiled at the same time for quiet operation. Follow the manufacturer's instructions for oiling the shaft bearing.

The venting system should be inspected at the start of each heating season. Check the vent pipe from the boiler to the chimney for signs of deterioration by rust or sagging joints. Repair if necessary. Remove the vent pipe at the base of the chimney or flue and using a mirror, check vent for obstruction and make certain the vent is in good working order.

The boiler flue gas passageways may be inspected by a light and mirror. Remove the burner door, figure 18. Place a trouble lamp in the flue collector through the draft relief opening. With
