c CAUTION:
ONLY a qualified oil-heating contractor shall install and adjust this oil
burner, using calibrated combustion test instruments, to ensure safe and
reliable operation of the furnace.
ONLY two (2) oil burner models shall be used with the Crown furnaces,
o R.W. Beckett model AF specification number EFL-102, or
o Carlin Combustion model EZ1-HP specification number 10250.
This furnace has been tested and approved for use when burning No. 2
distillate fuel (home heating) oil ONLY.
Introduction:
These instructions list the steps required to field install a R.W. Beckett or a Carlin
Combustion oil burner assembly in any of the Crown oil-fired furnace models
previously noted. The factory ships all Crown furnace models without the oil burner
installed. The burner package is separate from the furnace. As one of several tasks
necessary to complete installation of the furnace, the burner must be removed from
the shipping carton, mounted in the furnace, and connected to the furnace wiring
harness. Consult the furnace instruction manual, Crown Oil-Fired Central Furnace
Installation, Operation, and Service Manual with User’s Information Section, for
further assembly and adjustment requirements.
The size of nozzle installed in the oil burner determines the rate of heat output from
(heating capacity of) the furnace. Four (4) heat input rates are permissible:
85,000; 105,000; 120,000; and 140, 000 BTUH.
Base oil nozzle selection (i.e. heating capacity of the furnace) on a rate of heat loss
(heating load) calculation performed for the building. Use the procedures developed
in manuals provided by the Air Conditioning Contractors of America (ACCA) or the
American Society of Heating, Refrigeration and Air Conditioning Engineers, Inc.
(ASHRAE) to make these calculations.
Refer to the Residential Load Calculation, Manual J, from the ACCA, and the
ASHRAE Handbook Fundamentals
volume, from ASHRAE, for recommended
practices in heating load calculation for a residence. To obtain copies of these
publications for a fee, contact the ACCA and the ASHRAE at the addresses given in
Appendix A of the furnace instruction manual.
Installation:
The oil burner ships in a carton separate from the furnace. In the field, it is
necessary to mount the oil burner, secure it to the furnace, and connect the wiring
harness to complete the burner installation. Refer to the following steps.
