4.2.3 Accessing the Analyzer Probe Port
The unit contains a 1/8” NPT port at the rear of the exhaust manifold. This port is located above
the condensate drain connection as shown in Figure 4-2. Prepare the port for the combustion
analyzer probe as follows:
Accessing Analyzer Probe Port
1.
Refer to Figure 4-2 and remove the 1/8” NPT plug from the rear of the exhaust manifold.
2.
If necessary, adjust the stop on the combustion analyzer probe so it will extend mid-way
into the flue gas flow. DO NOT install the probe at this time

4.2.4 Connecting Multimeter to Flame Detector
During Combustion Calibration, the flame strength generated by the flame detector is measured
using a multimeter set to the µA scale. The flame detector is mounted on the intake manifold
flange as shown in Figure 4-3.
Proceed as follows to set up the multimeter to measure the flame strength current:
