factory. If the ignition process fails, the instrument will attempt to ignite
the flame 4 more times. If it continues to fail after the fifth attempt, a
flame failure message will appear on the display. If this occurs refer to
Section 5.
4.4.1 Verification of the Flame Guard Circuit
The operation of the flame guard circuit has been checked at the
factory, but should be re-verified during start-up. Use the following
procedure after ignition of the flame has been achieved:
1.
Turn off the fuel at the supply cylinder.
2.
Observe the fuel pressure gauge on the analyzer control panel. The
gauge indication will decay as the fuel in the line is exhausted.
When the gauge reading reaches near zero, the flame will
extinguish as the fuel solenoid shuts off the fuel supply. The
analyzer will automatically try to re-ignite. After 5 attempts, it will
display: flame failure, check air, fuel and the flame failure LED
will be on.
3.
Open the cylinder supply valve and re-ignite the flame by
pushing the up and down buttons simultaneously.
4.4.2 Ignition and/or Flame Guard Circuit Failure
If the flame ignition or guard circuits do not operate as described in
the above two sections, set the instrument fuel regulator to the
recommended pressure. If still fails to ignite, proceed as directed in
Chapter 5:

4.5 Sample Pump
A built-in sample pump is provided to draw sample gas from
ambient air. The gas flow rate should be maintained at about 1000 to
1200 cc/minute using the Front Panel flow control valve (clockwise
increases flow). See Figure 1-1.
4.6 Analyzer Operation
Although the Model 4060 has been programmed for your application
at the factory, it can be further configured at the operator level.
Depending on the specifics of the application, this might include all or a
set of the following procedures:
