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

Carbon Monoxide Facts
• Odorless
• Colorless
• Tasteless
• Mixes well in air
• Poisonous

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

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!

• CO and Efficiency Tests can be billable services
• Reduce Call Backs from improper installs or trouble-shooting
• Prevent unnecessary warranty disputes
• Professionalism of having the right tools for the job
• Professionalism of being a solutions provider
You are providing safety, comfort, and savings
Without measurements you’re just guessing!
• Differentiate the company and yourself
Offer something your competition doesn’t offer or
Offer it in a superior format
Why Test: Revenue, Cost Reduction, & Professionalism

What to test…
• Oxygen (%O2): primarily determines complete combustion
• Carbon Dioxide (%CO2): 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
