Description

The Burnham Commercial V9A boiler is ideal for use in commercial installations because it is versatile enough to meet specific job requirements. The V9A provides the durability of a cast iron boiler, assembled with the time-proven integrity of cast iron nipples. The sectional design of the V9A makes it easy to maneuver and install in existing boiler rooms. A packaged and fire tested V9A 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 V9A 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 V9A 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 V9A 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.
