General Information
The GD-21 is a 120VAC plug in type unit, with a self-contained alarm. The standard calibration is to 25% of LEL (Lower Explosive Level) of a mixture of Methane (natural gas) and air. The GD-21 will alarm at about 25% of LEL of Propane, Butane and LP Gas.

To detect the complete list of gases on the data sheet will normally require a special calibration, for a nominal charge. However, the following gases can be detected with the standard calibration: Acetylene, Gasoline fumes and Lacquer thinners. See the GD-21 data sheet for a list of other gases that can be detected, and other technical information.

Location
The unit on average can cover about 900 sq. ft. The coverage depends on air movement in the room or facility. Locate the unit high if the gas of concern is lighter than air, such as natural gas (methane). If the gas of concern is heavier than air; such as butane, propane, alcohols or gasoline; mount the detector relatively low. Extra detectors may be needed near any areas were people work or the air is stagnant.

The location selected should not be near a corner, as this can be dead air space. The location selected must also have a 120 VAC power outlet within nine feet. It is not suggested to locate gas detectors in kitchens or bathrooms, because of frequent unwanted alarms due to the normal use in those rooms of products containing combustible gases.
