Make: Burnham Commercial
Model code: FH-277
Series: Series 4FH
Type of Fuel: Gas/Oil
Height: 70-5/8 inches

Additional info:

4FH Saves on Installation It is a compact boiler that fits where other designs of similar capacity cannot. Available for 15 PSI steam and 30 or 60 PSI water*, the 4FH can serve perfectly as the heart of almost any system. As it is forced-draft fired, no tall, expensive stack is required. And because it is a factory-assembled, packaged unit, expensive jobsite time and labor are reduced. *60 PSI water boiler available in sizes 4FH-63 through 4FH-993. 4FH Saves in Operation The furnace surrounds the flame with highly efficient waterbacked primary heat-absorbing surfaces. This large combustion chamber is easy to fire, accommodating many forced-draft burners without flame impingement or other critical firing problems. Forced-draft firing makes the 4FH inherently more efficient than boilers using outmoded atmospheric burners, and gives you a feature that atmospheric units cannot offer: the option of burning gas or oil. A dual-fired burner allows you to burn the more economical fuel or the most readily available fuel at the flip of a switch, and affords you leverage in negotiating fuel prices. The 4FH is an economical heat source, whether used singly or in multiples. In fact, 4FHs with modulating burners may be sequenced to operate in a step-fired system more cost effectively than a large number of residential-sized boilers when ongoing maintenance costs are considered. 4FH Saves on Maintenance The 4FH is easy to clean and maintain, requiring no special tools, materials, or skills. Opening the front flue door allows firetubes to be brushed out quickly unlike the watertubes used in some boilers, which can be virtually impossible to clean. There are no elaborate or expensive proprietary seals required to reclose the doors as with some boilers. And, as the 4FH is a wetback boiler, there is no delicate or expensive rear refractory to maintain as with some dryback boilers.
