WARNING
DO NOT ATTEMPT TO START, ADJUST OR MAINTAIN
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 JBE and JBEX
burners requires the skills of an experienced and prop-
erly trained burner technician. Inexperienced individuals
should not attempt to start or adjust this burner.
THE INSTALLATION OF THE EQUIPMENT SHALL BE
IN ACCORDANCE WITH THE REGULATION OF
AUTHORITIES HAVING JURISDICTION, INCLUDING

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.
1. Nameplate Information
Each burner has a nameplate with job details, similar to
the nameplates shown in Figure A-1. The "X" in the JBEX
refers to a low NOx burner, where FGR is used to reduce
the NOx in the combustion gases. If the burner is not a
low NOx burner, there is no X in the model.
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
atomized burners (Figure A-1) show both the oil pressure
and air pressure. Pressure atomized burners only list the
oil pressure. 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 (Figure A-1). The maximum and minimum
inputs are shown in Figure , based on the type of fuel.
Other conditions, like the supply gas pressure or the
combination of fuels, emission requirements and control
systems may limit the turndown.
The minimum furnace sizes are given in Figure A-4.
These are for combination, straight oil and 60 ppm NOx
(gas) burners. For gas only with no FGR, the lengths
can be 10% less. For 30 ppm NOx on gas, the minimum
dimensions must be 5% larger. The volume heat release
(VHR) is defined as the total input (BTU/hr) divided by
the furnace volume (ft
listed. Application testing and related burner adjustments
can be done to handle smaller furnace configurations.
Turndown is defined as the ratio of the maximum input to
the minimum input. For example, a burner with a maxi-
mum input of 120 GPH and a minimum input of 12 GPH
