Safety valve
The following safety precautions apply to the safety valve in the hot water circuit and corresponding overflow
pipe:
▪ Do not block the outlet on the overflow pipe from the safety valve.
▪ 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 burning yourself.
