Installations at Altitudes of 0 to 4500 ft.Units are tested and approved for elevations of 0 to 4500 feet (0 to 1372 meters). Installations at Altitudes above 4500 ft.For elevations above 4500 feet (1372 meters), install the unit according to the regulations of the local authorities having jurisdiction and, in the USA, the latest edition of the National Fuel Gas Code (ANSI Z223.1) or, in Canada, the latest edition of the CAN1-B149.1 and .2 codes.
