The water pressure in the system when cold must be approx. 1 bar; otherwise bring it to that value.
•
The circulating pump must not be blocked.
•
The expansion tank must be filled.
•
The gas flow and pressure must match that given in the respective tables.
•
The condensate evacuation system must be efficient with no leakage or obstructions.
