unit gas piping inlet should be replaced to the one supplied with your unit.
(Thermal insulator over the flange connection should be field-supplied).
NOTE:
The factory-supplied flange should be welded with the connection pipe before connecting the
valve. Mount the Insulation's after the pipe brazing. Take particular care upon connecting
flange so that Insulation is correctly located.
