8.12 CO emissions check
In case air/gas combustion adjustment has been performed
check emissions using reference values in tables 25 and 26.
8.12.1 Access to measuring port
▶ Open a hot water tap and let the appliance work for 2 or 5
minutes.
▶ Remove the screw from the flue adaptor on the left side of
the appliance, as seen in fig. 60.
▶ Insert analyzer probe into the measuring port. The tip of the
probe should be in the center of the flue pipe (approx 1.5"
inserted). Avoid air gaps between probe and measuring
port as they can alter readings.

Allow the appliance to stabilize before
performing CO readings.
Let appliance warm up and wait for 2 or 5
minutes for each CO readings.
This will avoid wrong CO readings.
