High Altitude Conversions
For high altitude installations in the United States, refer to the
American Gas Association guidelines for the gas designed appliances
derating method. For elevations above 2,000' (610 m), input ratings are
to be reduced by 4% for each 1,000' (305 m) above sea level.
When the appliance is installed at elevations above 4,500' (1,372 m),
the certified high altitude rating shall be reduced at the rate of 4% for
each additional 1,000' (305 m). Refer also to CSA-B149.1 Natural Gas
and Propane Installation Code, local authorities, or codes which have
jurisdiction in your area regarding the derate guidelines.
CAUTION: The gas supply shall be shut off prior to disconnecting the
electrical power, before proceeding with the conversion.
