Burners 400,000 Btu input and under are exempt(10 Boiler hp, 3 gph oil, 115 kw electric)

All boilers must comply with CSD-1 sections CW & CE

Control compliance and operation based upon:400,000 to 2,500,000 Btu input

60 Boiler hp max.2,500,000 to 5,000,000 Btu input

120 Boiler hp max.5,000,000 to 12,500,000 Btu input

300 Boiler hp max.

ASME CSD-1 2009 “CF” Three DivisionsControls need to be provided and operate based upon the burner input rating

Burners 400,000 Btu input and under are exempt(10 Boiler hp, 3 gph oil, 115 kw electric)

All boilers must comply with CSD-1 sections CW & CE

Control compliance and operation based upon:400,000 to 2,500,000 Btu input

60 Boiler hp max.2,500,000 to 5,000,000 Btu input

120 Boiler hp max.5,000,000 to 12,500,000 Btu input

300 Boiler hp max.
