8 SERIES BOILER INSTALLATION AND OPERATING INSTRUCTIONS
Special Burner Harness Requirements
All of the Burner Harnesses will have an ORANGE wire.
At the time of shipping it is not known if the burner will
be fi ring a steam or water boiler. On all water boilers the
ORANGE wire is not required and will terminate in the
"Burner Harness" connector with no corresponding pin
or wire in the "Boiler Harness" connector.
The "Burner Harnesses" on the Carlin and Riello burners
have a RED wire not found on the Beckett harness. The
Carlin 60200 control offers a post-purge feature that
cleanses combustion byproducts after the call for heat is
satisfi ed. A constant supply of power must be provided to
run the blower motor for the post-purge feature. A similar
power requirement is found with the Riello burner. The
Riello burner is equipped with an electric shutter that
requires constant power for closing after the call for heat
has been satisfi ed. The Beckett "Burner Harness" does
not have the red wire because the GeniSys control that is
used does not have a post-purge feature, and the burner
does not have an electric shutter.
