Gas valve vacuum

Gas valve vacuum
What is the purpose of the vacuum line to the gas valve?
I have 4 year old Comfortmaker 100K Btu high eff furnace. It will not light with the vacuum line attached to the valve. If it is taken off it will run and shut down. I would guess it is some kind of safety switch so I have not run it.
Any ideas of what would cause this?
Thanks
Jeff
