Part 3. Checking/Adjusting the CO2
It is very important that the
combustion system be set within
the recommended CO2/ CO
measurements listed in Table 3.
Visually looking at the burner does
not determine combustion quality.
Failure to measure combustion
with a calibrated combustion
analyzer and set the throttle within
the recommended CO2/CO
measurements could result in
property damage, severe personal
injury, or death.
1. Preparing the measuring equipment
Remove the flue test port plug as
illustrated, and insert a calibrated
combustion analyzer.
Make sure the analyzer is set to the
appropriate fuel.
It is required to use a calibrated
combustion analyzer to verify final
adjustment according to the combustion
chart (Table 3).
Failure to do so could result in serious
personal injury or death.
Figure 6 - Combustion Test Port
Adjustments to the Gas valve may
only be made by a qualified gas
technician, while using a calibrated
combustion analyzer capable of
measuring CO2 and CO. Adjustments
may only be performed if the gas
line pressure is maintained above
minimum levels throughout the
duration of the test. See Table 3.
Failure to follow these instructions
may result in serious injury or death.
FAILURE TO PERFORM THE FLUE
GAS ANALYSIS AND ADJUSTMENT
AS DETAILED IN THIS SECTION
MAY RESULT IN ERRATIC AND
UNRELIABLE BURNER OPERATION,
LEADING TO REDUCED EFFICIENCY,
INCREASED FUEL CONSUMPTION,
REDUCED COMPONENT LIFE,
HEAT EXCHANGER COMBUSTION
DEPOSITS, AND GENERAL UNSAFE
OPERATION. FAILURE TO FOLLOW
THESE INSTRUCTIONS MAY RESULT
IN SERIOUS INJURY OR DEATH.
