12.4.3 Gas Piping Inspection
Inspect around the unit for gas odor following the procedure outlined in the operating instructions
in Section 12.4 at the end of this chapter.
WARNING!
If any gas leaks are found or suspected, shut the unit down
immediately. Use a gas detection device or bubble test to locate
the source of the gas leak and repair at once. Do not operate the
unit until the leak is corrected. Failure to comply with this procedure
could result in severe personal injury, death or property damage.
12.4.4 Flame Pattern and Combustion Verification
To verify the flame pattern and combustion, perform the following procedure.
Verifying Correct Flame Pattern and Combustion
1. Verify the flame pattern through the inspection port of the heat exchanger. The flame should
be blue and stable. The flame should be the length of the burner head openings.
WARNING!
The combustion testing and adjustments must be performed by a
qualified installer, service agency or the gas supplier. All
combustion measurements must be performed with calibrated
equipment to ensure proper reading and accuracy.
2. Test for CO2 or O2 and for CO during high firing rate. The combustion readings should be
within the range listed in Table 12-1. The CO level should not exceed 100 ppm when
combustion is correct. Perform the following procedure to manually place the burner into high
fire.
a) Press the round INSTALLER button, as shown in Figure 12-1.
b) Enter the installer access code “054” by using the LEFT and RIGHT buttons to select a
digit and the UP and DOWN buttons to change the digit. Press the OK button to enter
the access code.
c) Press the RIGHT button to highlight the Manual Operation icon then press the OK button.
