1. Ratings shown are for elevations up to 2,000 ft. For elevations above 2,000 feet, ratings should be
reduced at the rate of 4% for each 1,000 feet about sea level. (In Canada see rating plate.)
Reduction of ratings requires use of high altitude kit.
2. Data taken at 65ºF ambient and unit fired at full-rated input. Mounting height as measured from
bottom of unit, and without deflector hoods.
