INSIGHT

NOTE: An analyzer that is used to test natural gas furnaces

normally requires less frequent cleaning than an ana-

lyzer used for testing coal or oil fired furnaces.

Equipment Required:

• Alcohol

• Aerosol can of automotive carburetor cleaner

• Clean rag

• Source of compressed air (optional)

Procedure:

1. Remove gas-sample hose from top of water trap.

CAUTION: Carburetor cleaner attacks plastic compo-

nents! Take precautions not to spray cleaner onto the

probe handle or analyzer.

2. Insert the plastic-spray tube of the carburetor cleaner into the gas-

sample hose, and then liberally spray carburetor cleaner through the

hose and out the probe tube.

3. After spraying, remove all the residual cleaner by repeatedly flush-

ing the gas hose and probe tube with alcohol.

4. Wipe off the surfaces of the probe and tubing with a clean rag.

5. Allow the parts to dry completely. If available, blow compressed air

through the probe to expedite the drying process.

6. Reconnect gas-sample hose to top of water trap.
