1)
Notify your gas supply company if the static
gas supply pressure falls outside the stated
range.
2)
Where the rated pressures deviate, observe
the limits in accordance with the regulations
of the relevant country.
Please note: The pressure drop on
the flue gas side must not exceed
200 Pa, that on the ventilation air
side 50 Pa.

Explanations regarding Table 8.1:
1)
At rated output, 80 °C flow temperature, 65 °C cylinder temperature, 45 °C DHW temperature and 10 °C cold water temperature
2)
Explanation: The specific water flow rate to EN 825 is the cold water flow rate when raising the average temperature by 30 K, that can be
delivered by the GasSolarUnit/GasCompactUnit in the course of two consecutive drawings of 10 minutes duration respectively, starting from a
primary temperature of 65 °C. This is based on the standard dwell time of 20 minutes between drawings. The GasSolarUnit/GasCompactUnit
achieves this value even at shorter delays.
