Emissions
By means of the Pre-mix burner, the Clearfire boiler provides environmentally friendly emissions
when firing natural gas; emission data are shown below.
Table 6. Emissions
*ppm levels are given on a dry volume basis and corrected to 3% oxygen (15% excess air)
Noise Level
The Model CFC-E is extremely quiet at all operating levels, does not require any sound level
modifications to provide ultra low noise levels, and is virtually vibration free. Thus, it is very suitable
in applications that demand low noise levels.
