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.
