GENERAL INSTRUCTIONS
• Before seasonal start up it is advisable to have
a competent service agency check the boiler for
soot and scale in the fl ues, clean the burners,
and check the gas input rate to maintain high
operating ef fi ciency.
• On steam boilers make certain the boiler is fi lled
to the water line as indicated in fi gure 12. The
gauge cocks should be normally open. To remove
dirt from the gauge glass the petcock may be
opened to fl ush out the glass.
!
WARNING
Discharge will be boiling hot water.
• The radiator valves on a one-pipe steam system
must be either wide open or tightly shut. Do not
attempt to regulate room temperature by partially
closing the radiator valve.
• Air vents on steam radiators and the supply main
release air from the system. If radiators do not
heat satisfactorily, make sure the air vents are
clean and operational.
• The lever of the safety valve, shown in fi gure 12,
on the boiler should be operated periodically to
make sure that it is functioning properly.
!
WARNING
Discharge will be boiling hot water and
steam.
• The safety valve should open before the steam
pressure exceeds the 15 lb. reading on the gauge.
If this pressure is exceeded and the safety valve
does not open, it must be replaced. If the safety
valve leaks steam when the boiler is operating
at normal pressures, it should be immediately
replaced. Corrosion can build up rapidly at the
valve seat and prevent its functioning as a safety
device.
• During the heating season the drain valve, on the
bottom rear of the boiler, should be opened once
a month to fl ush out the boiler so the device will
be free to function properly. Use a pail to catch
the discharge.
!
WARNING
Discharge will be boiling hot water.
• If the water in a steam boiler appears to be
dirty or oily, or the water level in the gauge
glass fl uctuates considerably, the boiler should
be cleaned and skimmed (See page 21 for
instructions). A competent service person will use
approved cleaning compounds and properly clean
and fl ush out the boiler. He/she should also clean
or replace air vents and traps, clean fl ue passages
and check for proper operation of all controls and
safety devices.
• 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 fl ue and, using a mirror, check for obstruction.
• Boiler fl ue gas passageways may be inspected
by a light and mirror. Remove the burner access
door, ( fi gure 12). Place a trouble lamp in the fl ue
collector through the draft-hood relief opening.
With the mirror positioned above the burners, the
fl ue gas passageways can be checked for soot or
scale.
