3.2 Sensor Location

Gases have different densities. Some are heavier than air and concentrate at the bottom of a space. Some are lighter than air

and gather at the top. Consider the density of the gas you want the sensor to detect when you install the sensor. Some

examples are given below.

Heavier than Air Gas

Sensor Location

Bottled LP (liquefied petroleum) Interior wall; 18-24" from floor.

 D

locate directly above or beside gas appliances (ovens,

heaters).

 Avoid locating anywhere near a vent or window or near an outside

doorway.

Propane

Butane

Gasoline

Trichloroethylene

Vaporized hydrocarbons

Hydrogen sulfide

Lighter than Air Gas

ensor Location

Natural gas (methane) Near ceiling.

 D

locate directly above appliances where it is subject to

direct exposure to heat or steam.

Ammonia

Hydrogen

Same Density as Air Gas

Sensor Location

Carbon Monoxide 4-6 feet above the (generally uniform) floor.

 D

locate in direct air currents of windows, doors, or vents.

If you have a question involving the location of a unit or sensor, please contact your distributor or ENMET personnel. A
