Gas Leak Detector
User's Guide
Introduction
Congratulations on your purchase of the Extech FG100 Gas Leak Detector. The FG100
detects the presence of propane or natural gases. Careful use of this detector will provide
years of reliable service.
Description
Operation
Static Electricity
The metal conductor protruding from the back of the detector is used for static tests. Before
detecting a leak (and at a safe distance from the testing area), touch the conductor with one
hand and, at the same time with the other hand, touch an earth grounded metal object such as a
heater or cold water pipe. If the user is statically discharged, the yellow indicator will light for a
short period. If there are strong charges present, gas detection measurements should not be
taken since discharges could ignite leaking gas.
Leak Detection
1. Remove the protective sensor cap.
2. Slide the ON/OFF switch to the ON position. The Red indicator will light and the audible tone
will sound for a short period of time and then the Green indicator will light.
3. Perform the static electricity test.
4. Trace the sensor around the source of the suspected leak.

Application
This device can be used to detect gas leaks from small liquid gas containers such as camping
cartridges, lighters, soldering torches, etc. This device is not suitable for continuous operation,
industrial use, or complex systems such as heaters and ovens.
Safety

Do not get the sensor wet. Avoid extreme dampness
Do not expose the device to high temperature, high humidity, or strong vibration
Avoid mechanical stress to the device. Do not touch the sensor
Clean with a soft, dry cloth or brush. Do not use liquid, abrasives, solvents, etc.
Battery Installation/Replacement
When the status indicators fail to light with the ON-OFF switch in the ON position, replace the
two (2) ‘AAA’ batteries. Slide the battery compartment cover off (rear of the detector) to access
the batteries. Replace the batteries observing polarity and close the compartment. Remove the
batteries if the detector is to be stored for long periods of time.

When Gas is Detected
When a leak is detected, the red indicator will light and an audible tone will sound. Open all
doors and windows. Avoid open fire and sparks, leave the room, and do not operate any
electrical switches (light switches, etc.). If possible, turn off the gas supply. When the
concentration of gas falls below detectable limits, the red indicator and audible tone will no longer
activate when tests are taken. Note that false alarms are possible due to the presence of aerosol
sprays, tobacco smoke, etc.
Testing the Gas Leak Detector
Hold a gas lighter close to the sensor and allow the unlit lighter to leak a small amount of gas. If
the detector is working correctly, the red indicator will light and the audible tone will sound. If the
light and sound do not activate, the batteries may be weak or the unit is defective.
Note on Liquefied Gases
Liquefied gases are heavier than air and therefore settle on the floor. For this reason, the highest
concentration of gas is close to the ground.
