The boiler irrigation flow rate must be at least equal to Pinst/25 (Pinst =
instantaneous power in Th/h - 1 Th/h = 1.163 kW).
The circulation pump must be sized according to the maximum power
delivered.
In the exchanger, never exceed the flow rates specified in paragraph
3.4.
The boilers are equipped with the following elements:
• an anti-return flap,
• a manual drain tap,
• a flow rate controller.
It is imperative to fit the boiler and its installation with the following components:
• isolating valves on the flow and return taps,
• an expansion tank,
• a safety valve rated at 4 bar max. (as close to the outlet as possible),
• an effective drain mechanism,
• a filling mechanism (to be installed on the return tap),
• a drain mechanism.
