If the combustible gas channel is calibrated to a gas other than methane, use an appropriate
multigas cylinder.
1 . Install the demand flow regulator onto the calibration cylinder.
2 . Connect the sample tubing to the demand flow regulator.
3 . Install the sample hose and probe on the GX-6000 inlet fitting. Make sure the probe’s
