Wall Mount Installation

Affix the SQN8x transmitter to the wall at a height of 5 ft. (1.5 meters)
from the floor. Affix all sensors at an appropriate height and location, as
shown in the table. Place the sensors in a perimeter around a heat sink,
a boiler or all other equipment that should be monitored.

(1 ft.) from the floor. For combustibles that are lighter than air,
sensors should be installed 30 cm (1 ft.) from the ceiling, close to
the potential leak source.
