FGR connection is standard. Leave FGR flange cover in place when flue gas recirculation is not required for low emission burner technology. If not currently using the FGR connection for low NOx operation, choose a location that allows future access for interconnecting piping to the burner. If desired length is not an exact "L" dimension, use the next largest available "L" dimension.
