NOTES:
Heat ratings are for natural gas heat exchangers operated at or below 2000 ft (610 m). For information on propane or alti-
tudes above 2000 ft (610 m), see the Application Data section of this book. Accessory Propane/High Altitude kits are also
available.
In the USA the input rating for altitudes above 2000 ft (610m) must be derated by 4% for each 1000 ft (305 m) above sea
level. In Canada, the input rating must be derated by 10% for altitudes of 2000 ft (610 m) to 4500 ft (1372 m) above sea level.
