*In th e U.S.A., th e input r a ting for altitudes above 2000 ft (610m) must be reduced by 4% for each 1000 ft (305 m) above S ea level.
In Canada, the input rating f or al titudes from 2001 to 4500 ft (611 to 1372 m) above sea level must be derated by 10% by a n authorized gas conversion stationordealer.
For Canadian Installations from 2000 to 4500 ft (610---1372 m), use U.S.A. column 2001 to 3000 ft (611 to 914 m).
