V9

The Burnham Commercial V9 boiler is ideal for use in commercial installations because it is versatile enough to meet specific job requirements. The V9 provides the durability of a cast iron boiler, assembled with the time-proven integrity of cast iron nipples. The sectional design of the V9 makes it easy to maneuver and install in existing boiler rooms. A packaged and fire tested V9 will fit through a standard 36-inch doorway and will fit into a confined area, requiring only 9-inches from a right-side wall and 6-1/2 feet of vertical clearance. The V9 can also be factory fire tested before shipment in order to reduce the time and expense of setting up the burner on the job site. Knockdown V9 Series boilers were designed to be assembled one section at a time, using individual draw rods, a 1-1/16” ratchet and combination or open-end wrench. The sections are surface ground to ensure smooth mating. An elastic sealant and fiberglass rope are used on all section joints for a completely sealed and pressure-tight assembly. As with all Burnham Commercial cast iron products, the V9 is assembled using precision-machined cast iron push nipples, which ensure the most reliable watertight seal. Nipples are machined to exact tolerances so that when pressed into the nipple ports of the sections, they will conform to the shape of the ports. Unlike gaskets, nipples are impervious to breakdown from hot flue gases or petroleum based chemicals, including corrosion inhibitors, pump lubricants and antifreeze. V9 sections are carefully made at the state-of-the-art Burnham Foundry, LLC, in Zanesville, Ohio. Each individual section is hydro-tested at two-and-a-half times the maximum allowable working pressure at the foundry. The sections are then sent to Burnham Commercial for final machining. Factory-assembled sections are tested again to ensure the final assembly is leak-free.
