Page 4Testo USA,Presentation Title (version), Author, Date, Confidentiality Why Combustion Test: Safety Carbon Monoxide (CO) can be lethal Over 500 deaths / year; 15,000 ER visits/ year CO originates from incomplete combustion Reasons for the formation: Fuel rich mixture Improper venting Cooling of the flame temperture

6. Page 6Testo USA,Presentation Title (version), Author, Date, Confidentiality Why Test: Efficiency Combustion Efficiency = Fuel Savings 1% increase in efficiency nets 1% fuel savings Ensures the equipment is operating at optimal efficiency Saves on both fuel and electricity usage Customer expects the system to operate at stated efficiency There is a difference between combustion efficiency and AFUE Customer receives what they expect Performance Verification

7. Page 7Testo USA,Presentation Title (version), Author, Date, Confidentiality Why Test: Operation and Longevity Heat Exchangers Cracked HX investigation via O2 - Monitor for changes in O2 when blower starts and stops - Monitor O2 during ventilation air test as outlined in the Intl. Fuel Gas Code, Appendix D Nether should affect furnace operation or the O2 reading!

9. Page 9Testo USA,Presentation Title (version), Author, Date, Confidentiality What to test… Oxygen (%O 2 ): primarily determines complete combustion Carbon Dioxide (%CO 2 ): the maximized value relative to efficiency and “ideal combustion”, but does not necessarily indicate complete combustion. Carbon Monoxide (CO): lethal gas formed from incomplete combustion Excess Air: Needed to show complete combustion, but high values indicate high heat stack loss – poor efficiency. Efficiency: represents the total amount of heat available from the fuel minus the losses from the gasses going up the stack Temperature (ambient and stack): Needed to determine efficiency Draft pressure: Confirms the proper venting of combustibles out of the flue, an appliance has 5 minutes to prove draft under ANSI standards Pressure: Confirmation or setting of gas pressures
