This section covers the installation procedures for the
JBE burner line. Your specific burner will not have each
of the systems discussed and may be supplied as an
installed system. If you receive the burner as part of a
new boiler for example, the burner will be installed in the
vessel with the piping already done. For this reason, a
review of the installation is required to determine which
tasks are complete and which need to be done.
THE INSTALLATION OF THE EQUIPMENT SHALL BE
IN ACCORDANCE WITH THE REGULATION OF
AUTHORITIES HAVING JURISDICTION, INCLUDING
THE NATIONAL ELECTRICAL CODE, INSURANCE
REGULATIONS AND ALL LOCAL CODES.
The equipment shall be installed in accordance with the
state and local requirements and in Canada, in accor-
dance with Provincial Installation Requirements, or in
their absence, the CGA B149.1 and B149.2 codes shall
prevail. Authorities having jurisdiction should be
consulted before installations are made.
NOTE TO INSTALLER: The main power disconnect
for this equipment must be conspicuously labeled and
placed within sight of the operating system and equipped
with lockout provisions.
1. General Considerations
In the initial planning of the installation, several items
must be covered:
a. Prior to starting the installation, collect and review all
technical literature to identify requirements. These
should include Installation & Operating Manuals for
the burner and vessel, the wiring diagram, fuel
schematics and technical literature on controls.
b. A general overview of the equipment should be
made prior to installation. Check the location of
access doors to insure they will function properly
when all equipment is installed. The burner and
control panel should have sufficient clearance for
the operator to monitor and perform maintenance. A
minimum clearance of 24" all around the burner
should be provided for maintenance. The burner
drawer and oil gun are pulled out from the front of
the burner so there must be sufficient space for this.
c. A source of combustion air must be provided for the
burner. Local codes often determine minimum
requirements, and these must be followed. In the
absence of other codes, the following can be used.
Webster recommends two air sources be provided,
one located high, one low. Each air source must
be at least 1 ft
. If there are multiple burners, the area

must consider all burner requirements. Exhaust fans
are not recommended as they create additional air
flow requirements to include in the area calculation.
The quantity of air required for combustion and
ventilation is 10 cfm/BHP. The maximum air velocity
is 250 ft/min from the floor to 7 feet high, and 500 ft
min above 7 feet high. Outdoor louvers may restrict
the open area, and if the exact restriction is unknown,
a restriction of 20% can be used. Add 3.5% to the
area for each 1000 ft above sea level. Calculations are,
Total air required (cfm) = BHP x 10
Open area = cfm / velocity
Louvered area = open area x 1.2 (or actual)
Area of opening = louvered area / 2
For example, with duct located under 6' for a 500 HP
boiler, what would their area need to be? The total air
is (500 BHP x 10 cfm/BHP) = 5000 cfm. The maximum
velocity is 250 ft/min, so the open area must be =
(5000 cfm / 250 ft/min) = 20 ft
will have louvers, the actual openings must be = (20 ft
x 1.2) = 24 ft
be = (24 ft
The location of the combustion air source must not
create a condition where the burner or vessel comes
in contact with very cold air (under 40
large fluctuations in combustion air temperature. Cold
air can cause condensation below 40
burner and below 50
There should be no large variations in combustion air
temperature supplied to the burner. The burner can be
adjusted to handle temperature variations of 30
may not be able to handle swings of 50
combustion deterioration. In conditions where this can
occur, conditioning of the combustion air must be done
by location, baffling or pre-heating of the air. Seasonal
tune-ups also help cover large temperature swings.
d. There are several people that should be notified
before starting, including the owners representative,
the mechanical contractor, the electrical contractor,
the service organization and the boiler manufacturer.
e. DO NOT USE TEFLON TAPE or compounds with
Teflon content as an oil or gas pipe sealant. Teflon can
cause valves to fail creating a hazard. Warranties
are nullified and liability rests with the installer when
evidence of Teflon is found.
f. Installer must clearly identify the main electrical power
disconnect and the manual shutoff valve on the gas
supply drop line to the burner.
