* For all installations, the fl ue collar is included with the unit and should be fi eld installed per the instructions included with the unit.
† Ratings shown are for unit installations at elevations between 0 and 2,000 feet (0 to 610m). For unit installations in U.S.A. above 2,000 feet (610m), the unit input
must be derated 4% for each 1,000 feet (305m) 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 No. 54), (also refer to Table 7).
For installations in Canada, any reference to deration at altitudes in excess of 2,000 feet (610m) are to be ignored. At altitudes of 2,000 feet to 4,500 feet (610 to
1372m), the unit must be derated and be so marked in accordance with the ETL certifi cation. See Table 7 for USA and Canadian fi eld deration information.
