The Sample In, Sample Bypass Out, and Burner Exhaust Out gases and fittings
can reach temperatures of up to 250 °
°°
° C. Make connections to these fittings when
the oven heater is disabled or the module is powered down.
(See Figure 2-1) Connect inlet and outlet lines for sample, burner fuel and air, exhaust,
bypass, regulated air, and purge to appropriately labeled fittings on the rear panel. All
connections are 1/4-inch ferrule-type compression fittings except the PURGE AIR IN and
OUT connections, which are 3/8-inch compression fittings. The Burner Exhaust is a 3/8-inch
connection.
It is recommended that no connection be made to the PURGE AIR OUT port. If, however,
the analyzer's location requires interconnection with a venting system, the 3/8" O.D. line
should be kept as short as possible, and no longer than four feet.
CAUTION: POSSIBLE INSTRUMENT DAMAGE
No connection should be made to the PRESSURE RELIEF VALVE fitting. Doing
so may cause damage to the instrument.
