Crown Bermuda BSI069, Bermuda BSI172, Bermuda BSI103, Bermuda BSI138, Bermuda BSI207 Information Sheet

Bermuda gas-fired steam boilers provide
a wide range of sizes 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 Bermuda 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 powder­coated jacket resists scratching. Plus,
it’s insulated to retain heat.
The Bermuda meets all national
standards, and the heat exchanger
meets the specifications of the
American Society of Mechanical
Engineers.

Bermuda is the latest in a series
of designs that CROWN engineers
have created for ease of use,
constructed for long life, convenient
to install and service, and engineered
to provide the most value for each
energy dollar.
