Oil Burner and Oil Nozzle Installation

c CAUTION: This oil furnace is designed to use No. 2 or lighter distillate fuel
(home heating) oil. A Bio-fuel mixture may be used but the mixture is not to exceed
a B5.
This furnace is designed to utilize the following specially modified, oil burner:
 R.W. Beckett Corp. model AFG burner, specification # EFL-201
 Carlin Combustion Technology, Inc. model EZ-1HP, specification 99032B-1
NOTICE: NO other burners may be used in this application.
The heat output from the furnace is fixed, based on the size of nozzle installed in the oil
burner. Three (3) heat input rates are permissible: 70,000, 85,000, and 106,250 BTUH.
Nozzle selection (i.e. heating capacity of the furnace) shall be based on a rate of heat
loss (heating load) calculation for the building. These calculations should be made
according to the manuals provided by the Air Conditioning Contractors of America
(ACCA) or the American Society of Heating, Refrigeration and Air Conditioning
Engineers, Inc. (ASHRAE).
Refer to the Residential Load Calculation, Manual J, from the ACCA, and the ASHRAE
Handbook Fundamentals volume, from ASHRAE, for the recommended procedure to
compute the design heating load of a residence.
The oil burner was installed in the furnace at the factory. In the field, if it is necessary to
adjust the heating capacity of the furnace by changing the oil burner nozzle, refer to the
oil burner manufacturer's operating instructions (included with the furnace) for detailed
instructions on this procedure.
The furnace may have been handled roughly while in transit. Under some conditions, the
combustion chamber can shift out of position. A chamber retainer is used to hold the
chamber in place, do not remove or put the furnace into operation without it (see
Appendix D). Check for proper alignment of the burner air tube with the circular opening
in the combustion chamber and trial fit the burner to check the insertion depth of the oil
burner into the combustion chamber.
The end of the burner air tube should be inserted no farther than 1/4 inch back from the
inside surface of the combustion chamber, refer to Figure 1. Do not allow the burner
tube/end cone to physically touch or protrude into the chamber. High temperatures in the
combustion chamber can result in damage to the tube, the end cone, or both. A distance
greater than 1/4 inch back from the inside chamber wall may cause flame impingement
on the combustion chamber wall and subsequent sooting or carbon char buildup.
