(a)Heating Performance limit settings and rating data were established and approved under laboratory test conditions using American
National Standards Institute standards. Ratings shown are for elevations up to 2000 feet. For elevations above 2000 feet, ratings
should be reduced at the rate of 4% for each 1000 feet above sea level.
(b)AFUE is rated in accordance with DOE test procedures.
