2-7 INSTALLATION CONSIDERATIONS CHECKLIST

Verify the following:

•The Analyzer’s location should be:

Clean

A well ventilated area

weatherproofed

Non-hazardous

Vibration-free

Have stable ambient temperature

•The gas cylinders should be equipped with a clean, hydrocar- bon free two stage regulator and shut off valve.

•All external tubing, regulators, valves, pumps, fittings, etc. are clean.

•The correct fuel type is being used.

•The bypass line connection must be slanted down a minimum of 6 degrees from horizontal for drainage of water condensation.

•If required, thermal insulation around the bypass fitting to pre- vent condensation in the bypass restrictor.

•If required, thermal insulation for the sample inlet connection to minimize the cold spot.

•The heated line is at the correct temperature.

•The sample, zero, and span gases are at the correct tem- perature.

•The heated line to have over temperature protection.

•The sample, bypass, and burner exhaust tubing material must handle high temperature and have thermal insulation to protect from burns.

•The purge air out tubing to be 3/8 inch and less than 4 feet in length.

•The THC content of the supply gases are compatible with the analysis range.

•The calibration background gases are similar to the sample.

•The purge air out, burner ex- haust, and bypass are vented to atmospheric pressure. The pres- sure should be constant.

•The burner exhaust tube must be slanted down a minimum of 6 degrees from horizontal.

•All external gas connections have been leak checked.

•The dead volume for external sample and fuel lines have been minimized.

•The stainless steel tubing used for the fuel and sample lines is clean.
