Table 9.3 - Blower Model BTP Accessory Transformer Size (kVA) o
j 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 above sea level.
(In Canada see rating plate.) Reduction of ratings
requires use of a high altitude kit.
k 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.
l 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.
Model HDC motors are open drip proof, while model
BTP motors are totally enclosed and all single phase
motors have built-in thermal overload protection.
m Amp draw data shown is operating amp draw at
incoming power. For units that use a field installed
accessory step-down transformer as noted, the amp
draw shown is the primary side operating amp draw.
For sizing of circuit protection for equipment with
transformers, please refer to the National Electric
Code.
n For BTP models, add the Motor Amp Draw and Control
Circuit Amp Draw to get the Total Unit Amp Draw.
o Transformers for blower models are typically
smaller than those used for propeller
models, as the transformer is not needed for
the blower motor. Size 300-400 use a PSC power
exhauster motor, further reducing the required
transformer size.
