3.0 Installation
The SE-5175 sensor/transmitter detects gas only at the sensor location.
N OTE : 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
Hydrogen sulfide Interior wall; 18-24" from floor.
•
D O N OT locate directly above or beside gas appliances (ovens,
heaters).
•
Avoid locating anywhere near a vent or window or near an outside
doorway.
Lighter than Air Gas Sensor Location
Ammonia Near ceiling.
•
D O N OT locate directly above appliances where it is subject to
direct exposure to heat or steam.
Hydrogen
Same Density as Air Gas Sensor Location
Carbon Monoxide 4-6 feet above the (generally uniform) floor.
•
D O N OT 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
technician will analyze the question and recommend a location.
