The piping is incorrect for a steel or cast iron product installed in a large water volume system. First, the bypass is a system bypass not a boiler bypass. Second it is only 1/2" pipe when it should be full size as the supply and return. Third, when installed properly you will need to adjust it for fuel savings and proper boiler protection. Boiler bypass piping will protect against thermal shock and flue gas condensation. I will e-mail you the proper diagram.
