A. Pressure Control - Remove cover and note pressure
setting. With boiler operating, decrease setting.
When setting is lower than boiler pressure, control
will open and turn off boiler. After checking pressure
control, reset control to original setting.
B. Mechanical Low Water Cut-off - May be checked by
opening blow-off valve on lower portion of cut-off
body while boiler is running. This will drain water
from boiler and break circuit to burner.
Re
fi
ll boiler to its normal water line.
C. Primary Control and Flame Sensor - Check
1.
Flame Failure
- Simulate by shutting off oil supply
with hand valve while burner is on. Sixty seconds after
fl
ameout, safety switch locks out, ignition stops, motor
stops and oil valve - when used - closes. To restart, open
oil supply valve and reset safety switch.
2.
Ignition Failure
- With burner off, close oil supply
valve and run through start-up procedure. Safety
switch should lock out as in
fl
ame failure.
3.
Power Failure
- Turn off main power supply switch
while burner is operating. When burner stops, restore
power and burner should start. If operation is not as
described as above, check wiring and controls.
Preventative maintenance of oil
fi
red boiler reduces
operating costs. Boiler and vent pipe should be inspected
for accumulation of soot or scale deposits periodically
but at least once every year before start of each heating
season. When soot is present on section walls and
fl
ueways, improper combustion will result, causing
additional sooting and scaling until
fl
ueways are completely
closed. To remove soot and scale from
fl
ueways, remove
top jacket panel, top clean-out plate, open burner swing
door. See
Figure #14.

Damage to chamber could result.
Recommend replacing nozzle at start of each heating
season. Lubricate burner motor and circulator motor - if
required - with few drops of good grade of light motor
oil. Do not over oil. Have quali
fi
ed service person service
burner and check controls and check electrodes for carbon
or cracks in insulators. Burners should be adjusted to
produce conditions shown in
"Startup and Adjustment of Oil
Burner."
