Commercial, Forced Draft, Oil or Gas Fired, Hot Water or Steam Boiler

Ten reasons why you need the SERIES 24 commercial boiler:

	It’s a CROWN! Satisfied customers are our goal. So, all Crown boilers employ the latest technology for performance and safety.
	Cast iron construction – Cast iron heat exchanger sections and push nipples provide long life. Cast iron resists the effect of petroleum-based chemicals such as corrosion inhibitors, pump lubricants and antifreeze. Cast iron push nipples are important because they expand and contract at the same rate as the sections they join, which provides integrity to the entire assembly
	Hot water or steam – The SERIES 24 has been designed to meet a wide variety of installations.
	Gas, oil or combination gas/oil fired - Customer’s preference in the choice of fuels for economy and availability may be an important part of the purchase decision.
	Easy assembly – Once in place, the sections are easily assembled using a 3/4-inch drive ratchet with a 1-1/16-inch-deep socket and a wrench. Short draw rods pass through the sections’ reinforced lugs, resulting in fast, strain-free assembly.
	Hassle-free maintenance – All regular maintenance access areas are located on the left side, allowing the SERIES 24 to be installed 9 inches from the right sidewall. Removable jacket panels and flue cover plates simplify access to the heating surfaces.
	Versatile venting options – The SERIES 24 is a forced draft boiler that eliminates the need for high chimneys or draft inducers. Uniquely, the boiler can be vented from either the top or rear for maximum installation flexibility. Rear outlet venting requires only 6-1/2 feet of vertical clearance from floor to ceiling.
	Convenient delivery in sections – Delivery is available in easily handled sections that can be maneuvered through doorways and down stairs making this boiler ideal for installations where the boiler room is not readily accessible.
	Optimum for large installations – Available in 10 sizes from 342,000 to 1,852,000 BTU/hr output.
	Tankless heater available for domestic hot water – Convenient for small spaces or difficult installations that preclude a separate water heater. Finned copper coil heats water fast, and piping is easier to install.
