Hi Amrit, 

Thanks for forwarding this to the mailing list. We were able to log in and verify that the flow set points have been adjusted: 
R1 = 6 
R2 = 18 
R3 = 42, flow is ~30lpm and the mfc is wide open. George is going to check to see if there is a regulator upstream of the MFC set too low to flow at 42. 

Thanks,

Hello George; 

Would you please check out the DC gas system, and check it 
off on our Hot Checkout page? 

Could you check out one thing for me? 
The reg.1, 2 and 3 gas flows are ~ 1, 11, 17 lpm. 
I think reg.1's flow should be about 2 lpm, not 1. 
Could you adjust this? 

thanks, Mac
