1. The building number where the boiler is located

1. The National Board number for each boiler

1. The contractor must complete the inspections listed within the date range.

1. The type of inspection(s) required

1.3.4 Combustion Efficiency: In conjunction with the BC Inspection (Fuel type; natural gas, #2 fuel oil, #6 fuel oil, coal, etc.), check the combustion efficiency of each boiler using a Bacharach Model ECA 450 or equivalent portable flue gas analyzer. Measurements shall be taken in accordance with ASME PTC 19.10-1981, Flue and Exhaust Gas Analyses, Section 3, Extractive Measurement Systems. Measurements will be measured or calculated and recorded on Block 51 of the AF Form 1222 Supplemental.

1. Ambient Air Temperature of combustion air (required 0 – 120 deg F range); required accuracy of ±2% between 32 – 120°F

1. Flue gas exhaust stack temperature (required 0 – 1200 deg F range); required accuracy of ±4% between 32 – 255°F / ±6% between 256 – 480°F / ±8% between 481 – 752°F / ±10% above 753°F

1. O2 concentration (required 0 – 15% measurement range); required ±0.3% accuracy

1. CO concentration (required 0 – 50,000 ppm range); required accuracy of ±5% of reading or 10 ppm whichever is greater in the range of 0 – 2,000 ppm / ±10% of reading in the range of 2,000 – 40,000 ppm

1. Hydrocarbons (required 0 – 5% range); required accuracy of ±5%

Additionally, the boiler inspectors must record additional information:

1. Fuel type (natural gas, #2 fuel oil, #6 fuel oil, coal, etc.)

1. Energy content (i.e., BTU/lb, BTU/CCF, BTU/gal, etc.) of fuel with ultimate analysis of fuel constituents if available from utility bills

1. Combustion efficiency

1. % excess air

1. % CO2

1. Supply HW/steam temperature (an IR thermometer reading from a bare HW supply pipe is sufficient data)

1. Indicate whether the boiler is condensing/non-condensing/or steam

1. Specify boiler model number in the manufacturer block 12

1. Block 13 boiler must be sized in "MBTUH" from the equipment data plate (do not use the 'KLBS/HR' option). Enter the manufacturer’s rating or capacity in millions of BTUs per hour (MBTU), one thousand pounds of steam per hour is approximately equal to 1 MBTUs or Boiler Horsepower (BHP) multiplied by 33.5 equals MBTU per hour.

Note: The combustion analysis will be performed when the outside air is no greater than 30°F and the boiler is up to equilibrium and has stabilized (i.e., not cycling). System operation should not be less than 20 minutes of consistent operation at full (Hi) burner (if applicable) while maintaining a stable steam system pressure. If system load is not acceptable for testing (i.e., boiler cycling), then the system load will be created by manually setting back building water temperature to no less than 130°F prior to performing combustion analysis. All testing will be performed in compliance with Bacharach Instruction 0024-9400.
