Installation

With the GD-2B faceplate mounted on the enclosure's rear-housing the unit can be surface mounted on a wall.

A thin mid-plate enclosure component is also supplied with the GD-2B to mount the GD-2B on a 2 x 4

inch (5.08cm x 10.16 cm) switch box - single-gang or "handy", provided by the installer.

Location

A GD-2B is usually located in each room (except kitchens or bathrooms) where there are gas appliances or

through which gas pipes pass. Do NOT mount the GD-2B in a corner. Do NOT mount the GD-2B in kitchens or

bathrooms - alcohol’s, ammonia, cleaning solvents, paint thinner, gasoline vapors, and aerosol propellants

(aerosol cans such as hair spray usually contain a combustible gas) may cause alarms. Do NOT mount the

GD-2B where the normal ambient temperature is below 32° F (0° C) or exceeds 120° F (50° C). If the gas used

is natural gas (methane) mount the GD-2B on a wall about one foot down from the ceiling. If the gas used is

propane (LP), mount the GD-2B on a wall or column one foot above the floor. Use the same spacing as for smoke

detectors 30-foot centers, 900 square feet per detector.
