Installation, Use and Maintenance
o Present the lowest water law which optimizes the condensation
operation.
For example, prefer a floor heating circuit to a radiator circuit.
o Being the most demanding circuit in operation time which
allows to irrigate more often the condenser and recover a
maximum of calories.
Example: Prefer a North circuit to a South circuit.
o In the presence of DHW production and in order to avoid
thermal discomfort on the circuit connected to the condenser:
• Favoring a volume of primary or secondary balloon
corresponding at least to the energy storage of the peak
flow 10 minutes avoids unwanted raises and raises
in temperature of the condensing boiler on the circuit
connected to the condenser:.
•
Make sure that the circulation rate is not oversized and
properly adjusted, in order to maintain good stratification
and limit untimely DHW relaunches.
INFORMATION :
The Grundfos circulators used on the 120/140 and 180/225 kW models
have a degumming screw to be used in case of mechanical blockage.
IMPORTANT :
Maintain pressure while turning, to properly activate the degumming.
