*In the U.S.A., the input rating for altitudes above 2000 ft (610m) must be reduced by 4% for each 1000 ft (305 m) above sea level.
In Canada, the input rating for altitudes from 2001 to 4500 ft (611 to 1372 m) above sea level must be derated by 10% by an authorized gas conversion station or
dealer.
For Canadian Installations from 2000 to 4500 ft (610 ---1372 m), use U.S.A. column 2001 to 3000 ft (611 to 914 m).

*When a unit is converted to propane, different size orifices must be used. See separate, natural ---to ---propane conversion kit instructions.
Based on altitudes from sea level to 2000 ft (610 m) above sea level. In U.S.A. for altitudes above 2000 ft (610 m), reduce input rating 4 percent for each addi-
{
tional 1000 ft (305 m) above sea level. In Canada, from 2000 ft (610 m) above sea level to 4500 ft (1372 m) above sea level, derate the unit 10 percent.
