Total Gas FID
A needle valve adjusts the flow of gas to
theTotal Gas FID ( usually FID#2 ).
The needle valve is located at the front
of the valve oven.
This is a 10 turn needle valve. Turning
the knob clockwise reduces the flow.
The flow is directed to a “tee” fitting
throughwhich theFID combustion air
flows typically at a rate of 250ml/minute.
