orientAtion
It is highly recommended that the PIRECL be
installed in the horizontal position. The detector
is not position-sensitive in terms of its ability to detect
gas. However, the weather baffle assembly provides
superior performance when the PIRECL is installed
with the baffle in a horizontal position.
