2.4.3 Safety valve
The following safety precautions apply to the hot water circuit’s safety valve with corresponding drain pipe:
•
Never block the connection to the safety valve’s overflow pipe
•
Water expands when it is heated, this means that a small amount of water is released from the system via the
overflow pipe. The water that exits the overflow pipe can be hot! Therefore, allow it to flow to a floor
drain where there is no risk of burn injuries due to scalding.
