Fire thermostat
There are two sensors in the fire
thermostat Kit: Sensor X13100040-
01 is factory-set to open at 57°C.
Sensor X13100040-02 is set to open
at 115°C.
Sensors are mounted directly in the
ductwork. They should be installed
where elements can respond quickly
to air temperature changes. If not
possible, the sensor may be
installed on a suitable bracket so
the air is drawn across the element.
Sensor X13100040-01 has to be
mounted in the return air duct.
Sensor X13100040-02 has to be
mounted in the supply air duct.
Note: Do not permit element guard
to touch internal parts. Do not
locate sensor where the air
circulation is restricted by baffles.
