SAFETY PRECAUTIONS
Good safety practices must be used when working on burner equipment. The potential energy in the electrical supply,
fuel and related equipment must be handled with extreme care to prevent equipment failures, injuries and potential
death.
Throughout this manual, the following symbols are used to identify potential problems.
WARNING
This indicates a potential hazardous situation, which if not avoided, could result in personal injury or death.
CAUTION
This indicates a potentially hazardous situation, which if not avoided, could result in damage to the equipment.
The following general safety precautions apply to all equipment work.
WARNING
IF YOU SMELL GAS, OPEN WINDOW, EXTINGUISH ANY OPEN FLAMES, STAY AWAY FROM ELECTRICAL
SWITCHES, EVACUATE THE BUILDING AND IMMEDIATELY CALL THE GAS COMPANY.
IN ACCORDANCE WITH OSHA STANDARDS, ALL EQUIPMENT, MACHINES AND PROCESSES SHALL BE
LOCKED OUT PRIOR TO SERVICING.
IF THIS EQUIPMENT IS NOT INSTALLED, OPERATED AND MAINTAINED IN ACCORDANCE WITH THE MAN
UFACTURERS INSTRUCTIONS, THIS PRODUCT COULD EXPOSE YOU TO SUBSTANCES IN FUEL OR FROM
FUEL COMBUSTION WHICH CAN CAUSE DEATH OR SERIOUS ILLNESS AND WHICH ARE KNOWN TO THE
STATE OF CALIFORNIA TO CAUSE CANCER, BIRTH DEFECTS OR OTHER REPRODUCTIVE HARM.
IMPROPER SERVICING OF THIS EQUIPMENT MAY CREATE A POTENTIAL HAZARD TO EQUIPMENT AND
OPERATORS.
SERVICING MUST BE DONE BY A FULLY TRAINED AND QUALIFIED PERSONNEL.
BEFORE DISCONNECTING OR OPENING UP A FUEL LINE AND BEFORE CLEANING OR REPLACING
PARTS OF ANY KIND,
• TURN OFF THE MAIN MANUAL FUEL SHUTOFF VALVES INCLUDING THE PILOT COCK, IF
APPLICABLE. IF A MULTIPLE FUEL BURNER, SHUT OFF ALL FUELS.
• TURN OFF ALL ELECTRICAL DISCONNECTS TO THE BURNER AND ANY OTHER EQUIPMENT OR
SYSTEMS ELECTRICALLY INTERLOCKED WITH THE BURNER.

This manual covers the Models JB1, JB2 and JB3 CYCLONETIC burners offered by Webster Engineering & Manufacturing Co., LLC. These burners can be used in a wide
variety of Cast Iron, Firebox, Firetube, Flextube and other
applications. They can fire gas, oil and combination gas
and oil with several different operating systems.
“X” in the model number refers to a low NOx burner,
where FGR or a NOx cone is used to reduce the NOx
in the combustion gases. If the burner is not a low NOx
TAIN THIS BURNER WITHOUT PROPER TRAINING
OR EXPERIENCE. FAILURE TO USE KNOWLEDGEABLE TECHNICIANS CAN RESULT IN EQUIPMENT
DAMAGE, PERSONAL INJURY OR DEATH.
The startup and maintenance of the JB burner requires the
skills of an experienced and properly trained burner technician. Inexperienced individuals should not attempt to start
or adjust this burner.
Every attempt has been made to accurately reflect the
burner construction, however, product upgrades and special order requirements may result in differences between
the content of this manual and the actual equipment.
These special components will be described in the information provided with the burner and should be used as the
controlling document.
NOTE: This manual must be readily available to all operators and maintained in legible condition.

The serial number represents the unique number for that
burner and is a critical number that will be needed for any
communications with Webster Engineering.
The input rates define the maximum and minimum inputs
for that burner, given in MBH for gas and GPH for oil. Air

sure. For gas firing, the gas manifold pressure is given in
“in wc” which is inches of water column.
The electrical ratings of the burner are given, with the voltage, current load, frequency and phase (this will either be
single or 3-phase). For motors, the motor HP is listed.
2. Ratings
The ratings for each specific burner are given on the nameplate. The general burner ratings are given in Specification Sheets that follow this section. The maximun inputs
are given, based on the type of fuel. Other conditions, like
the supply gas pressure or the combination of fuels, emission requirements and control systems may prevent the
burner from reaching the lowest firing rate.
3. Product Offering
The JB burner can fire natural gas, propane and digester
gas as well as all grades of light and heavy oil (#2, #4, #5
and #6 oils as defined by ASTM D396).
DO NOT USE GASOLINE, CRANKCASE OIL OR ANY
OIL CONTAINING GASOLINE.
e. Catalog cuts of the major components. These provide
details on the installation, adjustment and maintenance of
the components used on the burner.
5. Service, Parts and other Information
Service and parts are available from your local Webster
Representative. For a list of Webster Representatives,
please visit the Webster web site at:
www.webster-engineering.com or call 620-221-7464.
This burner is also available as a low emission burner, and
will have model designation JBX. Several low NOx rates
are available for all gas and light oil burners, with the stan
dard offering of 60 ppm and 30 ppm when firing natural
gas. Heavy oil is not allowed in combination with low NOx,
as the high sulfur content can recirculate from the vessel
through the burner when switched from heavy oil to gas.
Low sulfur heavy oil can be used with gas FGR, when the
sulfur is under ½% (the FGR is closed during oil firing).
The burner can also be equipped with a NOx cone for low
NOx on gas, which does not require FGR. (See Addendum 950064).
Figure A-2 lists the common variations and options avail
able on this product. The minimum furnace conditions are
given in Section C.
4. Your Complete Manual
In addition to this manual, there are several other docu
ments that should be considered as part of the complete
manual for the burner. All of these documents are needed
to support the installation and startup of the unit. These
additional items include:
a. The wiring diagram, which shows the limits and interconnection of the burner and vessel controls.
b. The gas and oil piping schematics, which show the
components and their relative positions in the piping train.
c. The unit material list which provides an overview of
the burner requirements and a complete bill of material,
including the part numbers and description for each item.
d. The flame safeguard manual provides the operating sequence for the burner management system. This will be a
critical document for troubleshooting any future problems.
