INSTALLATION
2.6 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, hydrocarbon 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 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 exhaust, and bypass are vented to atmospheric pressure. The
pressure should be constant.
The burner exhaust tube must be slanted down a minimum of 6 degrees from horizontal.
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 prevent 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 temperature.
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.
