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:
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
