Make sure that a free flow is always possible on the heating circuit. Very small water volumes or stop in the heating circuit may cause
operational disturbances.
*Note: On models with inbuilt HGW (Atlas) it has been found preferred by many installers to fit an automatic air bleeder in position 85*
on the hot water tank to avoid a later revisit to bleed the TWS coil. The reason why an automatic air bleeder may be more desired on the
TWS coil on HGW models is that the high temperatures will de-gass the water more efficiently than conventional technique.

Warning **As the water temperature becomes hot (Atlas, up to 95°C), a mixer
valve must be installed between the cold water and hot water pipes
to en-sure a lower domestic hot water temperature.
