The gas connecting set should be connected to the gas connection on the boiler.
The supply connecting set must be connected to the boiler supply connection (front connection on the boiler)
and the return connecting set (longest) to the boiler return connection (back connection on the boiler).
The open connection in the supply connecting set is meant for a pressure relief valve, and the open connection
in the return connecting set is to be used for a boiler bleeding valve.
