4.0 OPERATION
4.1 Performing a Test
4.1.1 Analyzer Turn On and Warm Up
Important:
The probe must be at room tem per a ture before
performing the fol low ing steps. The temperature measured
by the probe during warm up is the combustion-air tempera-
ture used by the analyzer for ef
fi
ciency calculation purposes.
1. Make sure that the analyzer is properly set up per Sec tion 3.0.
2. During warm-up, the analyzer’s probe must be located in the area
containing the burner’s combustion-air supply. If the burner is us-
ing room air, simply place the probe within the room. In the case
of a high-ef
fi
ciency furnace where combustion air is drawn in from
an outside source, place the probe within that area with the burner
op er at ing. After the probe is properly positioned, turn ON the ana-
lyzer by pressing its
I/O
button.
3. Wait for the analyzer to complete its 60 second warm-up period;
after which, the Fuel Screen is displayed. If errors were detected
during warm-up, the Sensor Error Screen will be displayed. If this
occurs, refer to Section 4.8.9 to correct the cause of the error.
4.1.2 Selecting a Fuel
1. With Fuel Screen displayed, use the or button to step through
the fuel codes until the proper fuel is selected. The analyzer de-
faults to the most re cent ly se lect ed fuel.
F1 = Natural Gas
F3 = LPG
F2 = Oil #2
F4 = Kerosene
2. Press the
ENTER
button to select the displayed fuel code;after
which, the analyzer enters the Run Mode.
4.1.3 Manual Zero of the CO Channel
(Model 60 only)
If the CO channel is set up for manual calibration (refer to Sec tion 3.5.3),
and if the CO reading shows a value other than zero in fresh air, then be-
fore proceeding with a test manually zero the CO channel per Section 5.5.
