J) BURNER AND CONTROLS
1. Burner Installations
Packaged boilers are shipped with the burner installed and prewired. Boilers that are shipped
knocked-down must be field assembled. Follow the procedures listed below to install and connect
the burner.
a. Remove the burner parts and instructions from the carton.
b. Referring to specifications at the back of the manual, check to see that the burner model and
size match the boiler model.
c. Make sure the correct nozzle is in place and is tightly sealed.
d. Check the electrode position and set the air intake as indicated in the burner manual.
e. The burner is installed with a mounting flange. The end of the burner air tube should be 1/4"
from the inside surface of the front wall of the combustion chamber.
f. Make the electrical connections as illustrated in the wiring schematics. All wiring must be done
in accordance with the local electrical code. A service box is provided with disconnect switch so
power can be shut off to the boiler, but power for a utility lamp is still available.
g. For units installed in Maine, New Jersey and New York, a low-water cutoff is required on all
hot water boilers.
2. Oil Primary Control - Chimney Vent (Non Post Purge Control)
The oil primary control with the solid state flame sensing circuit provides automatic, non-recy-
cling control of oil burners. When used with the cadmium sulfide flame detector, the control will
automatically control the oil heating system.
The primary control will stop the oil burner within a predetermined number of seconds if the fuel
fails to ignite or if the flame goes out during operation. The oil burner will remain off until the
reset button on the relay has been pushed.
WARNING:
The reset must never be pressed more than once during a single flame fail-
ure.
3. Oil Primary Control - Direct Vent (Post Purge Control)
The oil primary control with the solid state flame sensing circuit provides interrupted ignition.
Used in conjunction with a cadmium sulfide flame detector, the control will automatically con-
trol the oil burner.
The primary control will stop the oil burner within a predetermined number of seconds if the fuel
fails to ignite or if the flame goes out during operation. The oil burner will remain off until the
reset button on the relay has been pushed.
WARNING:
The reset must never be pressed more than once during a single flame fail-
ure.
Post-purge is provided to ensure that the boiler fires at maximum efficiency and dependability
throughout the heating season.
