general Performance data

➀

Ratings shown are for elevations up to 2,000'. For elevations above 2,000',

ratings should be reduced at the rate of 4% for each 1,000' above sea level.

(In Canada see rating plate.) Reduction of ratings requires use of a high

altitude kit.

➁

Data taken at 65°F ambient and unit fired at full-rated input. Mounting height as

measured from bottom of unit, and without deflector hoods.

➂

All motors used are produced, rated and tested by reputable manufacturers in

accordance with NEMA standards and carry the standard warranty of both the

motor manufacturer and Modine. All motors are totally enclosed and all single

phase motors have built-in thermal overload protection.
