In both, fuel is mixed with air and ignited, heating a sealed sleeping accommodation. Fresh, filtered air then blows beyond the exterior of the hot chamber and into the heating ducts.

Before performing annual furnace cleaning, Richard makes sure to switch off the electric power and the fuel supply. The distinctive red ability switchplate can usually be found at the acme of the cellar stairs or near the burner itself, while the fuel shutoff valve is near the oil tank or on the incoming gas pipage. Note the location of both in case of a future leak or burn down.

Step 2

Cleaning the Combustion Chamber

In the combustion chamber, fuel mixes with air and is ignited, generating heat—as well as carbon soot, water vapor, carbon dioxide, and worse. A buildup of soot can crusade the bedroom walls to corrode. Richard scrapes out built-up carbon using a small wire brush.

If the belt deflects more than ¾ inch when pressed firmly, it can be adjusted by sliding the motor backward slightly.

Step 6

Adjusting the Burner and Testing Efficiency

Person kneeling down by a burner to see if the furnace is in good condition.

Richard sets upward a combustion analyzer, which calculates furnace efficiency by measuring gasses in the exhaust flue. He makes sure that the burner'south air gates are adjusted for the proper ration of fuel to air. "You want the fuel that y'all've brought to the be burned before information technology goes upwardly the chimney," Richard says. He also replaces the oil nozzle, which atomizes the fuel just before information technology ignites, and checks the flame colour and shape at the igniter. For either oil or gas, this is a cardinal indicator of stable and complete combustion. In a gas system, this is the time when the burner tubes should be vacuumed make clean.

Step vii

Cleaning Floor Vents
