7.7. Cleaning the Probe

The probe tube and gas sample hose will become dirty under normal use.

NOTE: T

he water trap’s filter element should prevent soot from

reaching the analyzer’s internal components. If the probe is not kept

clean, it could become clogged and restrict the flow of gas into the

analyzer, resulting in incorrec

t combustion test readings and

calculations.

NOTE:

An analyzer that is used to test natural gas furnaces

normally requires less frequent cleaning than an analyzer used for

testing coal or oil fired furnaces.

7.7.1. Equipment Required

•

Alcohol

•

Aerosol Can of Automotive Carburetor Cleaner

•

Clean Rag

•

Source of Compressed Air (optional)

7.7.2. Procedure

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

CAUTION:

Carburetor cleaner attacks plastic

components! 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 flushing

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.
