Installation Instructions
Where to install the Transmitters
Recommended Installation Heights
The zone where the unit should be installed is determined by the type of
gas to detect (see the table below).
* May differ in certain applications. Since hot NO
2
from exhaust systems is
lighter than air, our empirical data has shown that NO
2
sensors are more
effective when installed closer to the ceiling.

The installation heights recommended represent general
guidelines. Always confirm with local laws and regulations, as
these take precedence over manufacturer’s
recommendations.
