Hi everybody

I don't have experience in GE frame 9FA machines, I am working in Frame 9E. If anybody can help me I would like to know the purpose of 3 GCVs used in Frame 9FA DLN 2 and the working modes like Diffusion mode, Sub piloted premix mode, Piloted premix mode and Premix mode of operation.

 

Try contacting Bob Johnston at the email address in this link and ask if he would be kind enough to send you the information he has. Easier than to try to explain from scratch here.
