IV-INSTALLATION
HYDRAULICDIAGRAM
* In the case where all the radiators of the installation are provided with thermostat valves,
provide a differential pressure valve between the boiler outflow and return
- Installation
These boilers are designed to be installed in a boiler room or in a service annex.
It is necessary to check the ventilation of such a place.
If the height of the flue is less than 6 m, provide a basic ventilation of 1.5 dm² per 17.5 kW.
If the height of the flue is more than 6 m, provide a basic ventilation of 1 dm² per 17.5 kW.
The boiler room must be in accordance with the regulations in force.
- Draught Regulator
It is necessary to provide, on the body of the flue, approximately 50 cm above the line of the connecting pipe, a draught regulator of a
diameter equivalent to that of the flue, which will be regulated according to the pressure losses of the boiler.
On stopping the burner, the valve will be held slightly open in order to ventilate the flue and to eliminate condensation mists.
- Connection to the flue
Before installing a piece of apparatus, we strongly advise that the installer checks the flue (soot deposits, air inlet interference, cracks, etc.)
in order to be sure that it is in a good condition. The efficiency of this boiler leads to relatively low fume temperatures. Special care must
be paid to the flue, which must be heat-insulated and leak-proof. In fact a lack of leak-proof quality and bad insulation of the flue will lower
the temperature of fumes, causing staining. One of the provisions to be made is to line the tubes. The quality of lining must be compatible
with the fuel used.
