GENERAL INSTRUCTIONS
Before seasonal start-up, it as advisable to 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.
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 10 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 for obstruction.
The boiler flue gas passageways may be inspected by a light and mirror. Remove the
burner door, figure 11 below. Place a trouble lamp in the flue collector through the draft relief
opening. With the mirror positioned above the burners, the flue gas passageways can be
checked for soot or scale.
The following procedure should be followed to clean the flue gas passageways:
1. Remove the burners from the combustion chamber by raising the burners up from
the manifold orifices and pulling toward the front of the boiler. See figure 11, below.
2. Disconnect the vent pipe from the draft hood.
3. Remove the top jacket panel.
