Gas-fired steam boilers
Sets the standard for single and multi-family residential and small commercial applications

JAMAICA3 gas-fired steam boilers provide a wide range of sizes (from 69,000 to 379,000BTU/HR input) that can efficiently service single family homes, multi-family residences and small businesses. An approved chimney is required.

Crafted with rugged, cast iron heat exchangers and stainless steel burners, the JAMAICA3 offers proven-in-service reliability, simplicity of design and economy in its purchase price and consumption of fuel.

The heat exchangers are built with steel push nipples below the water line where superior strength and resistance to expansion and contraction is important, and cast iron push nipples above the water line where corrosion resistance is key. The cast iron push nipples are larger than usually found on such units to provide optimum steam quality.

Attractive and durable, the powder-coated jacket resists scratching. Plus, it's well insulated to retain heat. The JAMAICA3 meets all national standards, and the heat exchanger meets the specifications of the American Society of Mechanical Engineers.

JAMAICA3 is the latest in a series of designs that CROWN engineers have created for ease of use, constructed for long life and engineered to provide the most value for each energy dollar. That's CROWN's commitment to quality.
