‡ Ratings shown are for unit installations at elevations between 0 and 2000 ft. (610m). For unit installations in USA above 2000 ft. (610m), the unit input must be derated 4% for each
1000 ft. (305m) above sea level; refer to local codes, or in absence of local codes, refer to the latest edition of the National Gas Code, ANSI Standard Z223.1 (N.F.P.A. No. 54).
For installations in Canada, any references to deration at altitudes in excess of 2000 ft. (610m) are to be ignored. At altitudes of 2000 to 4500 ft. (610m to 1372m), the unit must be
derated to 90% of the normal altitude rating, and be so marked in accordance with the ETL certifi cation.
