 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.
‚ Data taken at 55°F air temperature rise. At 65°F ambient and unit fired at full-rated input. Mounting height as measured
from bottom of unit, and without deflector hoods. For units equipped with deflector hoods, see page 27.
ƒ 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.
m For models sizes 200,250,300, and 350 the efficiency is 83% for 1 pipe vented installation and 82% for 2 pipe
separated combustion installation. Btu/Hr output shown is for 1 pipe vented installation, corresponding Btu/Hr output for
2 pipe separated combustion installation is 1 percentage point lower.
