NOTES: 1. Input and output must be derated 4% per 1000 feet above sea level when installed above 2000 feet altitude.

2. Dimensions are nominal.

3. For other boiler ratings:

Boiler Horsepower: HP = Output Radiation Surface: EDR sq. ft. = Output
33,475 150

4. Shipping weight is approximate, based on previous units shipped and can be effected by several variables
including the green or dry wood used in the crate.
