Owner’s Responsibility:
NOTICE
Follow These
Instructions Exactly
Failure to follow these instructions,
misuse, or incorrect adjustment of
the burner could lead to equipment
malfunction and result in asphyxiation, explosion or fi re.
Contact a professional, qualifi ed service agency for the
installation, adjustment and service of your oil burning
system. Thereafter, have your equipment adjusted and
inspected at least annually to ensure reliable operation.
This work requires technical training, trade experience,
licensing or certifi cation in some states and the proper
use of special combustion test instruments.
Please carefully read and comply with the following
instructions:
y
Never store or use gasoline or other fl ammable liquids
or vapors near this burner or appliance.
y
Never attempt to burn garbage or refuse in this appliance.
y
Never attempt to light the burner by throwing burning
material into the appliance.
y
Never attempt to burn any fuel not specifi ed and ap-
proved for use in this burner.
y
Never restrict the air inlet openings to the burner or the
combustion air ventilation openings in the room.
Professional Installer/Service Agency
Responsibility:
High altitude installations — Accepted industry practice
requires no derate of burner capacity up to 2,000 feet above
sea level. For altitudes higher than 2,000 feet, derate burner
capacity 2% for each 1000 feet above sea level.
Pre-installation check-
list
Protect Against Stray
Light Lockout
Failure to follow these instructions could cause
loss of burner operation resulting in no heat, an
unplanned process interruption, work stoppage
and the potential for frozen plumbing or other
cold weather property damage.
The control must detect a dark, no-fl ame condition in
y
order to start the burner or it will hold in the stray light
lockout mode.
y
Shield the burner from direct exposure to intense
light.
Protect Against Dust and
Moisture
Wet, dusty environments could lead to blocked
air passages, corrosion damage to components,
impaired combustion performance and result in
asphyxiation, explosion or fi re.
Follow These
Instructions Exactly
Failure to follow these instructions
could lead to equipment malfunction and result in asphyxiation,
explosion or fi re.
Please read all instructions before proceeding. Follow
y
all instructions completely.
y
This equipment must be installed, adjusted and started
by a qualifi ed service agency that is experienced with
all applicable codes and ordinances and responsible for
the installation and commission of the equipment.
y
The installation must comply with all local codes and
ordinances having jurisdiction and the latest editions of
the NFPA 31 and CSA-B139 & B140 in Canada.
NOTICE
50 Hz motors — The burner ratings, air settings and nozzle
ratings are based on standard 60 hz motors (at 3450 rpm).
Derate all ratings 20% when using 50 hz motors. Consult
factory for specifi c application data.
This burner is designed for clean, dry installations.
y
y
Electrical controls are not protected against rain or
sprayed water.
y
Keep the installation clear of dust, dirt, corrosive vapors, and moisture.
y
Protective covers and more frequent maintenance may
be required.
Adequate Combustion
and Ventilation Air
Supply Required
Failure to provide adequate air supply could se-
riously affect the burner performance and result
in damage to the equipment, asphyxiation, explosion or fi re hazards.
The burner cannot properly burn the fuel if it is not
y
supplied with a reliable combustion air source.
y
Follow the guidelines in the latest editions of the NFP A
31 and CSA-B139 regarding providing adequate air for
combustion and ventilation.
Page 4 6104 BCF3 R02
Combustion air supply
The burner requires combustion air and ventilation air for
y
reliable operation. Assure that the building and/or combustion air openings comply with National Fire Protection Standard for Oil-Burning Equipment, NFPA 31. For
appliance/burner units in confi ned spaces, the room must
have an air opening near the top of the room plus one near
the fl oor, each with a free area at least one square inch
per 1,000 Btu/hr input of all fuel burning equipment in
the room. For other conditions, refer to NFPA 31 (CSA
B1139-M91 in Canada).
If there is a risk of the space being under negative pres-
y
sure or of exhaust fans or other devices depleting available
air for combustion and ventilation, the appliance/burner
should be installed in an isolated room provided with outside combustion air.
Clearances
With the burner installed in the appliance, there must be
y
adequate space in front of and on the sides of the burner
to allow access and operation. Verify that the clearance
dimensions comply with all local codes and with the appliance manufacturer’s recommendations.
Fuel supply
Nozzle pressure
Correct Nozzle and Flow
Rate Required
Incorrect nozzles and fl ow rates
could result in impaired combustion,
under-fi ring, over-fi ring, sooting,
puff-back of hot gases, smoke and
potential fi re or asphyxiation haz-
ards.
Use only nozzles having the brand, fl ow rate (gph), spray
angle and pattern specifi ed by the appliance manufac-
turer.
Follow the appliance manufacturer’s specifi cations for
the required pump outlet pressure for the nozzle, since
this affects the fl ow rate.
Nozzle manufacturers calibrate nozzle fl ow rates at
y
100 psig.
y
This burner utilizes pressures higher than 100 psig, so
the actual nozzle fl ow rate will be greater than the gph
stamped on the nozzle body. (Example: A 2.00 gph
nozzle at 150 psig = 2.45 gph.
y
For typical nozzle fl ow rates at various pressures
see accompanying chart.
The fuel supply piping and tank must provide #1 or #2 fuel
y
oil at pressure or vacuum conditions suitable for the fuel
unit (oil pump) on the burner. Refer to fuel unit literature
in the literature envelope in the burner carton to verify allowable suction pressure.
Oil Supply Pressure
Control Required
Damage to the pump, fi lter or other compo-
nent seals could cause possible oil leakage
and potential fi re hazard.
The oil supply inlet pressure to the fuel unit cannot
y
exceed 3 psig.
y
Ensure that a pressure-limiting device is installed in
accordance with the latest edition of the NFPA 31.
If fuel supply is level with or higher than fuel unit —
When the fuel unit is not required to lift the oil, the instal-
y
lation is usually suitable for either a one-pipe or two-pipe
oil system. The oil pressure at the inlet of the fuel unit
must not exceed 3 psig.
Refer to the Mount the Burner Section of this manual for
y
one-pipe or two-pipe fuel supply installation instructions.
If fuel supply is below the fuel unit —
The fuel unit nozzle port pressure is factory set at 140
y
psig. Some original equipment manufacturer burner applications may call for a lower pressure to obtain a required
fi ring rate. Do not change this pressure unless directed to
do so by the appliance manufacturer.
Vent system
The fl ue gas venting system must be in good condition and
y
must comply with all applicable codes.
Electrical supply
Verify that the power connections available are correct for
y
the burner. All power must be supplied through fused disconnect switches.
Verify burner components —
Burner, Model CF375
y
Air tube assembly
y
Mounting fl ange kit
y
Oil nozzle, per Table 1 — Only 45° to 70° solid pattern
y
nozzles are recommended unless otherwise specifi ed by
appliance manufacturer. (See specifi c appliance recom-
mendation sheet or refer to OEM Spec Guide). Find the
required fi ring rate in the 150 psig column (factory-set fuel
unit pressure). Select the corresponding nozzle from column 1 (Rated gph @ 100 psig).
Use a two-pipe oil system when the fuel unit must lift the
y
oil more than 8 feet if burner is equipped with a B fuel
unit. The return line provided by the two-pipe system is
needed to purge the air from the fuel lines and minimize
the likelihood of air-related problems during operation.
