V9A Series
CAST IRON COMMERCIAL WATER OR STEAM BOILER
Your Commercial Heating Solution!
Available in ten sizes with gross output ratings from 347 to
1900 MBH, the V9A Series fires gas, oil or combination gas/oil
and is available equipped with either steam or water trim. The
Series V9A has thermal efficiencies up to 82.7% meeting AHRI
certification requirements.
Cast iron construction, ease of assembly, two venting options
and stringent testing methods make the V9A Series boiler by
Burnham Commercial your commercial heating solution.
American-Made Cast Iron Construction
Burnham Commercial’s unique cast
iron formula has an extremely high
silicon content, making it stronger
and more flexible. It offers better
thermal shock resistance and greater
heat transfer capabilities than other
cast iron products.
• MANUFACTURED WITH QUALITY
Casting Solutions operates a state-
of-the-art foundry, in Zanesville,
Ohio, ensuring quality and
availability of boiler sections.
• CAST IRON NIPPLE DIFFERENCE
V9A sections are held together using
cast iron nipples, which are well
known as being of the highest
standard for boiler construction.
Unlike gaskets used by many other
boiler manufacturers, cast iron
nipples are impervious to flue
gases, oils, petroleum-based
chemicals and other contaminants,
which means fewer costly repairs
and a longer lasting boiler.
Installation & Service Flexibility
The cast iron sectional design of the V9A boiler makes it easy
to maneuver through doorways and into the boiler room. In
addition to being shipped as loose sections, the boiler is available
with factory-assembled sections or as a completely packaged
and fire-tested unit. Packaged units, fastened to a steel skid, are
easily maneuvered through standard 36" x 80" doorways.
• HASSLE-FREE SECTION ASSEMBLY
V9A boiler sections have reinforced
lugs that are used to assemble the
sections with individual draw rods
resulting in fast, strain-free assembly.
The sections can be assembled
using two common tools–a 3/4"
drive ratchet with a 1-1/16" deep
socket and wrench. The sections are
surface ground to ensure smooth
surface mating. An elastic sealant
and fiberglass rope are used on all
section joints for a completely sealed
and pressure-tight assembly.
• EXTENSIVE TESTING METHODS — ASME APPROVED
Each boiler section is hydrostatically tested at 2-1/2 times
the rated working pressure at the foundry. Factory-assembled
sections are tested a second time at 1-1/2 times the rated
working pressure.
• REAR OR TOP VENTING
As a forced draft boiler, the V9A
provides optimum draft for
controlled efficiency, eliminating
the need for high chimneys or
induced draft fans. A unique
feature of the V9A boiler is that it
can be vented from the rear or the
top. This enables easy chimney or
sidewall venting for maximum
installation flexibility. Top outlet
venting saves floor space and
reduces installation time and
materials. A plugged tapping is provided
to make flue outlet pressure readings.
