You just installed a gas fired warm furnace what test must be made and the results left on site?

• A. Visual inspection
• B. Combustion test
• C. Pressure test
• D. Leak test

Answer: (B)

When a gas-fired furnace is installed, the key check is a combustion analysis. This test looks at how the appliance is actually burning the gas in real operating conditions—measuring the exhaust gases to verify the fuel-air mixture is correct, the venting and draft are adequate, and the level of pollutants like carbon monoxide is within safe limits. It also helps confirm the furnace is operating efficiently. Because it provides direct evidence of performance, the results are recorded and left on site for the property owner and for future servicing. A visual inspection only assesses surface condition and obvious defects; it doesn’t tell you how well the burner is operating or whether combustion byproducts are being produced safely. A pressure test focuses on the integrity of the gas supply line, and a leak test checks for leaks, but neither confirms proper combustion or safety under actual use. The combustion analysis is the step that validates safe, efficient operation and is the one typically documented on site.
