1. 4.0 Equipment Installation Aspects (Section 4.5 On-Rate for Fuel-Fired Equipment)

2. 4.5 On-Rate for Fuel Fired Equipment The contractor shall ensure the equipment combustion is “on-rate”, for gas-fired or oil-fired equipment, and is at the equipment nameplate value.

3. Combustion Appliances Gas appliance requirements similar but different than oil appliance requirements.

4. Oil Burner Smoke Test

5. Traditional Combustion Testing Kit

6. Electronic Combustion Testing Kit

7. Oil Nozzle Sizing & Spray Angle Pattern

8. Temperature Rise Method (oil appliances) Air Temperature difference between the Warm Air Supply Plenum and the Return Air Plenum

9. On-Rate On-Rate (also known as fuel flow rate): refers to volume of fuel flowing into the combustion process at steady-state operation. Once the measured flow is corrected for temperature and altitude, the on-rate can be established. For oil on-rate is rated in Btu/gal For gas it rated in Btu/ft 3

10. On-Rate For Combustion Appliances Gas Appliances: Clocking the meter, and Furnace Temperature Rise, or Combustion Analysis Per OEM Directions Oil Appliances Verify OEM Compliant Nozzle, and Verify oil pump pressure, and Furnace temperature Rise, or Combustion Analysis Per OEM Directions

11. Gas Combustion Appliances

12. On-Rate For Gas Combustion Appliances Clocking the meter per OEM instructions And Measuring Temperature Rise Or Perform a combustion analysis per OEM instructions

25. 4.0 Equipment Installation Aspects (Section 4.6 Combustion Venting System)

26. Acceptable Procedures Comparison of installation to appropriate gas venting tables for Category I vent systems Or Comparison of installation to appropriate gas venting tables for Category II, III, and IV vent systems

27. Appliance Vent Category National Fuel Gas and ANSI Appliance Venting Categories Appliance Vent Type Condensing/Non- Condensing Vent Pressure Common Vent Material Category INon-Condensing Non- Positive B-Vent Category IICondensing Non- Positive Special Per Manufacturer Category IIINon-CondensingPositiveStainless Steel Category IVCondensingPositivePlastic

28. Appliance Vent Category Category I is for residential and is most common it includes gravity fed and plus 80 furnace models Category II may be required for some residential boilers and wall vented water heaters Category III tank-less water heaters SS duct Category IV high efficiency with plastic pipe
