Safety valves

▪ Never block the connection to a safety valve's overflow pipe.
▪ The following safety precautions apply to the hot water circuit's safety valve with corresponding over-
flow pipe: Water expands when it is heated, which 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 to prevent any risk of burning yourself.
