Appendix B: Altitude De-Rating - Harman Stove Company Harman Clarity 828i Installation And Operating Manual

For U.S. installations, the Clarity Fireplace Insert
is approved for elevations up to 000 feet using
the factory-installed burner injectors. At elevations
above 000 feet, U.S. codes require a decrease in
the input rating by changing the burner injectors to a
smaller size. The chart below lists by part numbers
the appropriate injectors for both LP and natural gas
at various altitudes.
For Canadian installations, the Clarity Fireplace
Insert is approved for elevations up to 1370 meters
(4500 feet).

For high altitude installations above 1370 meters
(4500 feet), consult the local gas distributor or the
authority having jurisdiction for proper rating meth-
ods.
NOTE: The difference in altitude derating require-
ments for the U.S. and Canada is simply a result
of differences in testing standards between the two
countries.
If the installer must convert the unit to adjust for
varying altitudes, an information sticker like the one
below must be filled out and affixed to the appliance
at the time of conversion.
