• Ratings shown are for elevation up to 2000 feet above sea level (in Canada, refer to rating plate).
For elevations above 2000 ft., ratings should be reduced by approximately 4% for each 1000 ft. above sea level.
• Mounting Height is measured from the bottom of the unit.
• Heat Throws are calculated at 65°F ambient and unit fired at full rated input.
Throws for HDS30 and HDS45 are based on 8-foot mounting heights and at 10-foot heights for HDS60 and HDS75.
• S.P. = shaded pole, P.S.C. = permanent split capacitor
