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

IMPORTANT
For Innovation Water Heater installations in Korea, refer to the Natural Gas
Combustion Calibration procedures in Appendix K.
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 flange of the blower
side intake manifold as shown in Figure 4-3.
Proceed as follows to set up the multimeter to measure the flame strength current:
