18. Product Specifications
Note 1:
The heating capacity of the CHALLENGER is based on the
test requirements of the U.S. Department of Energy.
Note 2:
The AHRI rating is based on a piping and pick up allowance
of 1.15. This allowance should be sufficient for the
standard radiation requirements for a building load.
Note 3:
Based on the given AFUE the CHALLENGER meets the
energy efficiency guidelines established by Energy Star.
Note 4:
Input and output ratings are shown for sea level
applications. The CHALLENGER automatically derates the
input at approximately 2% for every 1,000 ft of altitude.
No alterations to the appliance or burner system are
required.
Note 5:
The trailing letter “s” in the model number refers to
CHALLENGER “Solo” Boilers (heating only). The
construction and components of these models are
identical to the combination (heating and domestic)
models except the domestic coil is removed from the heat
exchanger along with all associated domestic components
(domestic piping, domestic sensor, flow sensor, domestic
wiring and labeling). The combustion, safety, and
efficiency performances are identical to the combination
units.
The following efficiency performance is achieved when the CHALLENGER is operated as a boiler according to the
ASHRAE 103 test procedure.
