American-Made Cast Iron ConstructionÐ BC25-HSi

V9 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 V9 Series fires gas, oil or combination gas/oil and is available equipped with either steam or water trim. The product meets the energy efficiency requirements of ASHRAE 90.1 with combustion efficiencies up to 86%.

Cast iron construction, ease of assembly, two venting options, and stringent testing methods make the V9 Series boiler by Burnham Commercial your commercial heating solution.

American-Made Cast Iron ConstructionÐ BC25-HSi

Burnham CommercialÕ s unique BC25-HSi cast iron 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. BC25-HSi's properties allow Burnham Commercial to maintain the highest level of quality from start to finish, and provide a product that is optimized for hydronic heating applications.

•Manufactured with Quality

Cast iron sections are poured at

Burnham Foundry, LLC in Zanesville Ohio. The foundry uses state-of the-art technology and production

techniques which ensures the availability of high quality boiler sections.

•Cast Iron nipple Difference

While gaskets used by other manufacturers can break down from oils and contaminants, the

V9's cast iron nipples remain unaffected, ensuring long life and eliminating costly repairs.

The V9 section assembly includes precision machined cast iron nipples that expand and contract along with the sections they join, providing integrity to the entire assembly. Additionally, cast iron nipples resist boiler flue gases and petroleum based chemicals, including corrosion inhibitors, pump lubricants and antifreeze.

Installation & Service Flexibility

The cast iron sectional design of the V9 boiler makes it easy to maneuver through doorways and into the boiler room. In addi- tion 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

V9 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 toolsÑ 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

Each boiler section is hydrostatically tested at 2-1/2 times the rated working pressure at the foundry. Factory assembled sections are tested at 1.5 times the rated working pressure.

•Rear or Top Venting

As a forced draft boiler, the V9 provides optimum draft for controlled efficiency, eliminating the need for high chimneys or induced draft fans.

A unique feature of the V9 boiler is 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 take flue outlet pressure readings.
