3.  RECOMMENDED LOCATIONS OF DETECTORS:

 

  Install at least one natural (methane) gas detector on every floor level (see Figure 

1). 

  Install the detector close to every place that gas operated appliances are installed 

(see Figure 1). 

  Since natural (methane) gas is lighter than air (1:0.56), the greatest concentration 

of gas will be immediately under the ceiling.  Mount detectors on the wall with the 
top edge of the detector at a minimum of 6” (15cm) and a maximum of 12” (30.5 
cm) below the ceiling, and at least 2 feet (60.1 cm) from any corner (see Figure 2). 

  If the ceiling is sloped or higher than 8.5 feet (2.6 m), please ask your local Gas 

Company for advice about proper installation.
