Figure 1. Typical Burner Nameplate
A. Equipment Located in Con
fi
ned Space
The con
fi
ned space should have two permanent openings:
one near the top of the enclosure and one near the
bottom of the enclosure. Each opening shall have a free
area of not less then one square inch per 1,000 BTU’s
per hour of the total input rating of all equipment within
the enclosure. The openings shall have free access to the
building interior, which should have adequate in
fi
ltration
from the outside.
B. Exhaust Fans and Other Air-Using
Devices.
Size air openings large enough to allow for all air using
devices in addition to the minimum area required for
combustion air. If there is any possibility of the equipment
room developing negative pressure (because of exhaust
fans, for example), either pipe combustion directly to the
burner or provide a sealed enclosure for the burner and
provide it with its own combustion air supply.
C. Clearances to Burner and Equipment
Provide space around burner and equipment for easy
service and maintenance. Check minimum clearances
against those shown by the equipment manufacturer and
by applicable codes.
D. Exhausting Hazardous Fumes
See warning on this page. Also be conscious of any fumes
produced by the materials that are being heated. Always
ensure adequate ventilation to exhaust all fumes.
Nozzle Assembly
Maintenance
A. Replace the Burner Nozzle.
1. If applicable, remove the plastic plug protecting the
nozzle adapter threads.
2. Place a 3/4” open-end wrench on the nozzle adapter.
Insert the nozzle into the adapter and
fi
nger tighten.
Finish tightening with a 5/8” open-end wrench.

Adequate Voltage Required
A low or erratic power supply could result in impaired
burner operation, severe delayed ignition or an
explosion inside the heat exchanger resulting in a
burn and/or asphyxiation hazard.
y
The Model SDC requires a continuous supply of 11
to 16 volts DC at 25 amps measured at the burner
during operation.
y
An automotive or small engine charging system
that is capable of supplying the required continuous
voltage/amperage is recommended with certain road
equipment, such as asphalt hot patchers and similar
applications.
y
This is especially true while maintaining nominal load
temperatures during idle periods.
Adequate Combustion and
Ventilation Air Supply
Required
Failure to provide adequate air supply could seriously
affect the burner performance and result in damage
to the equipment, asphyxiation, explosion or
fi
re
hazards.
y
The burner cannot properly burn the fuel if it is not
supplied with a reliable combustion air source.
y
Follow the guidelines in the latest editions of the NFPA
31 and CSA-B139 regarding providing adequate air
for combustion and ventilation.
General Information
Your burner was designed, installed and adjusted at the
factory prior to shipment and should not require additional
adjustments. Refer to the Troubleshooting section of this
manual when experiencing a possible fault condition.
