3.3.5.2EFFLUENT

All the gases introduced into the detection cell vent from one fitting at the rear of the analyzer. TAI recommends that the cell be permitted to vent directly to the atmosphere wherever possible.

If a vent line is required, the installation must include a drop-out pot to collect the water that is formed by the burning of the hydrogen fuel. The vent line must be constructed so that water and dirt cannot collect in it.

3.3.5.3SAMPLE BYPASS VENT

The sample bypassed by the back-pressure regulation system vents from a separate port at the rear of the analyzer. If a vent line is required, it must be installed so that water and dirt cannot accumulate in it.

3.3.5.4FUEL AND AIR CONNECTIONS

The fuel used to provide combustion should be Hydrogen gas, zero quality with certified THC of less than 0.5 ppm and a pressure of 30 psig. The compressed air, ultra zero gas quality with THC less than 0.1 ppm should be used at a controlled pressure of 30 psig Connect the fuel and air sources to the instrument according to the gas connection diagram included at the back of this manual.
