The Versatile Boiler The Burnham 4F Forced Draft Steel Firebox Generator is a consistent sales leader in the heating industry, for reasons that make solid sense. 4F 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 4F 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 4F-63 through 4F-993. 4F 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 4F 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.
