The intelligent boiler...
The Challenger uses advanced logic control for
adjustable modulation, which automatically regu-
lates the capacity of the boiler to your require-
ments. The outdoor reset function monitors
outside conditions and adjusts the boiler system
water temperature for maximum comfort and
efficiency. The Challenger works with both regular
‘on/off’ and advanced programmable thermostats.
...but small enough to fit your closet
The Challenger was designed to fit into the
smallest of spaces. Its on-demand domestic
hot water function eliminates the space and
costs associated with hot water storage
tanks. Taking up less than 3ft
3
, the Chal-
lenger can fit in a small storage area or utility
closet. But with an attractive enclosure and
whisper quiet operation, why hide it at all?
Properly matching your boiler to your needs is
fundamental to achieving optimum performance.
With three sizes from 84 to 124 MBH, there is a
Challenger to fit your needs. Your installer can
properly measure your heating and hot water
requirements to ensure the perfect fit.

... with straight “A”s in efficiency
The condensing heat exchanger in the Challenger
converts the latent heat in flue gas into usable
energy. This results in an AFUE of 95%. The fuel is
burned clean enough to meet California’s SCAQMD
requirements for low NOx emissions.
