Purging the Gas Lines
After the gas lines have been connected and tightened, they should be purged to
eliminate contamination and maintain gas purity
before
opening the valves. This
process is controlled by system software. In most cases, this step will only need to
be performed once, unless the gas lines are removed and reattached or otherwise
opened to atmosphere.
