Gas Analyzer Installation and Gas Connections Guidelines:

Installation Site Requirements:

• Ensure unobstructed air exchange around the gas analyzer; avoid direct covering.
• The outlet and pressure compensation vent of the purging and monitoring unit FS870S must not be closed.
• Protect plastic and elastomer components of the housing against UV radiation.

Requirements for II 3G/Gb and II 2G/Gb Models:

• Protect the housing against brush discharges or electrostatic charging; clean with a moist cloth only.

Requirements for II 3D/Dc and II 2D/Db Models:

• Avoid installation in areas with an increased risk of electrostatic charging (e.g., near filling systems).
• Implement measures for the blow-off vent of the purging and monitoring unit FS870S to prevent zone elevation due to stirred-up dust.
• Install a suitable key switch to confirm interior cleaning before commissioning.

Connecting Combustion Gas and Combustion Air Supply:

• Follow the connection diagram for operational gases.
• Do not open the combustion gas path inside the gas analyzer; leakage can lead to fires and explosions.
• If the combustion gas path is opened inadvertently, check for leakage using a leak detector once closed again.
• Regularly check the leak tightness of the combustion gas supply line outside the gas analyzer and the combustion gas path inside the analyzer.

Shut-off Valve in the Combustion Gas Supply Line:

• Install a shut-off valve in the combustion gas supply line for safety during shutdown, instrument air supply failure, or a leak in the combustion gas path.
• Place the shut-off valve outside the analyzer house near the combustion gas supply source.

In Case of Instrument Air Supply Failure:

• Trigger a visible or audible alarm if the combustion gas supply does not shut off automatically during instrument air supply failure.

Note:

• It is preferable to evacuate the ignition protection gas into a dust-Ex free area.
• Clean the interior of the housing before switching on the gas analyzer; the initial purging is not for cleaning purposes.
• Refer to specific pages (mentioned in the text) for detailed procedures and checks related to gas connections, safety measures, and alarms.
