Notes:
1.
Ratings are shown for unit installations at elevations between 0 and 2,000 feet (610m).
2.
For unit installations in U.S.A. above 2,000 feet (610 m), the unit input must be field derated 4 percent for each 1,000 feet (305 m) above sea level;
refer to local codes, or in absence of local codes, refer to the latest edition of the National Fuel Gas Code, ANSI Standard Z223.1 (NFPA 54).
3.
For installations in Canada, any references to deration at altitudes in excess of 2,000 feet (610 m) are to be ignored. At altitudes of 2,000 to
4,500 feet (610 to 1372 m), the unit must be field derated and be so marked in accordance with the ETL certification.
4.
See
for U.S.A. and Canadian field deration information.
