• FILLING THE SYSTEM
When the hydraulic connections are finished you can connect the system.
Open all the air vent valves of radiators, boiler and installation.
WARNING!! The boiler is provided of an automatic water trap, in the case of the Hydrobox model, has 2 automatic traps.
Make sure that all the air vent devices are placed in the highest position of the installation because it might not be enough.
Do not forget to open the covers of the purgers in order to allow the air outlet.
Open the fill tap gradually making sure that all the air vent valves work normally. Control the installation is under pressure by using a gauge.
Pressure must be between 1.1 and 1.2 bars with an installation provided with a closed vessel. Close the fill tap and purge again the air on the
boiler through the air vent valve.
• HYDRAULIC SCHEMES
Now we show you a series of representative schemes with different hydraulic connections. These schemas do not preclude the obligation
and / or necessity by the fitter to install different components not showed (anti-electrolytic cuffs, expansion vessels, circulation pumps, back
end protection valves (thermal shock valves), water treatment systems, air vent valves, mixing valves, stopcocks ...) that makes more reliable,
durable and comfortable the installation or the boiler. Bronpi Calefacción only guarantee an optimal work of the boiler when the installation is
made with an accumulation tank (buffer tank), and only the fitter is responsible for the use or non-use of this.
