The IDD detectors are usually located on the boiler in a position that minimizes radiant or conducted heat
to the detector. In some cases, supplementary cooling chambers may be required. Typical installations

• The physical mounts are adequate to support the weight of the detector head in the position required
for operation.
• The ball valve lever of the cooling-air line moves through its entire operating range without obstruction
from any structure, cable, or hose.
• The cooling-air hose and I/O cable do not interfere with the operation of any moving components at the
boiler front. The I/O cable does not contact hot surfaces capable of melting its insulation.
• The cable must not run close to any cable or equipment carrying high voltage to keep interference to
minimum.
