* 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.
** 4-5" reducer supplied where required.
† Ratings shown are for unit installations at elevations between 0 and 2,000 ft (0 to 610m). For unit installations in U.S.A. above 2,000 ft. (610m), the unit input must be derated 4% for each 1,000 ft. (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 (N.F.P.A. No. 54), (also refer to Table 6).
