For information on propane or altitudes above 2000ft (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.
