CF-20 Centrifugal Fan and CHD-30 Model Heater
Figure 5C shows the factory configuration for the 20 HP application. Here the long leg of the angle points
toward the center of the heater to provide a 17" wide opening across the housing at the location of the
angles. No change is required to the heater.
Retrofit applications require holes to be drilled in the upper and lower profile angles and the vertical profile
angles to be installed with the noted hardware.
