The solid fuel boilers must be installed with all the securi-
ty devices foreseen by the laws in force.
For this purpose, AIREX boilers are equipped with a built-
in safety heat exchanger.
A) Connect the safety discharge valve (pos. 1) and insert its
temperature sensor into the bulb holder (pos.2)
The safety discharge valve may be mounted either on the
right or on the left.
It is recommended to convey the discharge of the safety
heat exchanger.
Remember that for the solid fuel boiler, due to the thermal
inertia of the fuel, the installation of the termal discharge
valve is required.
