Connection On The Dhw Side Of Cylinder Banks With Vitocell 300-H - Viessmann Vitocell 100-H Technical Manual

Installation — DHW cylinders
G Shut-off valve
H Flow regulating valve
K Pressure gauge connection
L Non-return valve
M Drain
Note
■ Safety valve F must be installed.
■ Recommendation: Install the safety valve higher than the top edge
of the cylinder. This protects the valve against contamination, scaling
and high temperatures. It also means that the DHW cylinder does
not need to be drained when working on the safety valve.
■ Observe information on the safety valve on page 29.
