Most room thermostats are equipped with an adjustable heat anticipator, set the
thermostat heat anticipator to match the control current of the furnace as indicted
on the furnace wiring diagram.
Combustion Chamber
The furnace combustion chamber is a hollow, circular cylinder sealed at the
bottom end and open at the top end. The chamber is made of a lightweight,
insulating, “soft”, refractory material. The refractory material is composed of
organically bound, alumina-silica fibers that protect the heat exchanger from the
intense heat of the oil burner.
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 # TP2501

Riello model BF3, specification # C8511325

Carlin model EZ-1HP, specification # 99032B
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.
NOTICE:
Remove all cardboard packing from around chamber before installing
burner.
For horizontal installation rotate mounting plate and chamber
retainer 90 degrees
left or right, depending on furnace position. DO NOT c hange the position of the
chamber. This unit is equipped with a chamber retainer. The retainer secures the
