Electrical Rating
Notes:
1
Listed Input and Output ratings are at minimum vent lengths at an altitude of 0-2000ft. Numbers will be lower with
longer venting and/or altitudes greater then 2000ft.
2
Ratings based on standard test procedures prescribed by the U.S. Department of Energy; certified by AHRI. CHS-399
efficiency represents Thermal Efficiency (AFUE is not applicable).
3
The CHS requires a special venting system, use only vent materials and methods detailed in these instructions.
4
When operating with Propane models CHS-85 and CHS-110 have min/max Input Modulation rates of 17.6/88 and
22.6/113 MBH respectfully.
Wall mounting of unit requires two people to lift the boiler into place. Failure to follow
these instructions may result in property damage or personal injury.
High Altitude Operation
The CHS boiler is designed to operate at its maximum listed capacity in installations located at 0-2000ft above
Sea Level. Since the density of air decreases as elevation increases, maximum specified capacity should be de-
rated for elevations above 2000 ft [610 m] in accordance with Table 2-2.

Elevations 2001 ft [610 m]

In Canada de-rate by 10%

In USA
Notes:
1
Canada: Altitudes between 2000-4500 ft [610-1372 m], de-rate by 10%. Consult local authorities for de-rating
capacities for altitudes above 4500 ft [1372 m].
2
USA: De-rate capacity by 4% for every 1000 ft [305 m] over 2000 ft [610 m].
Combustion – At elevations above 2000 feet, the combustion of the boiler must be
checked with a calibrated combustion analyzer to ensure safe and reliable operation. It is
the Installers responsibility to check the combustion and to adjust the combustion in accordance with
Section 9.0. Failure to follow these instructions may result in property damage, serious injury, or death.
