50,000 to 200,000 Btuh
93% Efficiency
Born and bred in the USA
The next generation.
Compact, sleeker,
more efficient.
• The world-class condensing boiler made
in the USA
• High efficiency—
93% AFUE
• Advanced design long life aluminum heat
exchanger. Large diameter waterways help
prevent plugging.
• 2 models, 4:1 modulation provides input
range of 30,000 to 120,000 Btuh and 50,000
to 200,000 Btuh
• Quiet operation
Reliable technology.
Low mass design.
The Bobcat boiler utilizes an advanced
low mass heat exchanger design that
makes it highly reliable and robust.
Bobcat’s patented 14-pass continuous
flow design, with 1-inch water passages,
helps maintain better velocity, prevent
plugging and virtually eliminates risk of
flashing into steam.
Knitted metal fiber burner.
Designed specifically for high efficiency
condensing boiler applications, ensures
extremely low emissions and full modulation. The burner’s metallic composition
enhances the flame detection signal for
reliable performance. The boiler utilizes
a reliable spark ignition system.
Modulation reduces wasteful
cycling, maximizes fuel savings.
Just as stop and go driving wastes fuel,
so does on and off cycling of your boiler.
On very cold days your boiler may
operate continuously to heat your home.
However, on warmer days, an ordinary
boiler with unchanging output will
repeatedly turn its burner on and off.
This puts out lots of BTUs for short
periods of time, wasting fuel with every
new ignition.
Microprocessor manages
boiler performance.
With information it receives from an
outdoor sensor, room thermostat, flame
sensor and other devices on the boiler,
the microprocessor monitors boiler performance and controls temperatures and
the sequence of operation. It also controls the domestic hot water temperature, boiler output and fuel saving
modes. LED readout on the control
panel displays current conditions, set-up
details and diagnostic information.
Knitted metal fiber burner is proven state-ofthe-art design.
Electronic boiler control optimizes efficient operation.
Easy-access terminal strip speeds wiring.
• 12 year limited warranty with 5 year parts and
labor warranty
• Floor standing or wall hung
• Natural or L.P. gas
• PVC/CPVC or stainless steel vent pipe—
up to 100 ft. equivalent length
• All connections on top
• Low NOx -- friendly to the environment
• Ideal for radiant, baseboard, DHW or mixed
applications
A major achievement in
sealed combustion,
condensing-boiler
evolution!
On warmer days, the Bobcat automatically
reduces its BTU input using a proper lower
level of fuel consumption. This reduces
cycling dramatically. In addition, the heat
exchanger enters the condensing mode.
Here, the Bobcat maximizes heat extraction
from the combustion process and
significantly reduces your fuel bills.
Serpentine water passages are 1" diameter to
help ensure trouble-free performance.
Beautifully designed for better performance,
smoother installation and the ultimate in
application versatility.
Control panel on front makes set-up and diagnostics simple. Provides important
status information.
