Combustion Gas Analyzer

This quick guide provides basic setup, operating and maintenance
information for the Fyrite® INSIGHT. If required, more detailed
information concerning the analyzer’s technical specifications,
operation, set-up, calibration, and parts list can be downloaded from

Setting Up the Analyzer

Front Panel Push Buttons

Note that a push button may perform several functions, depending on the analyzer’s model number
and what screen is being displayed at the time.

• Turns the analyzer ON and OFF.

• Turns the backlight ON and OFF while the analyzer is turned ON.

• Scrolls up, down, left, and right through the display screen options.

• Causes the displayed value to increase or decrease correspondingly.

• Acts as an ENTER button. Performs the action selected.

• While in the HOLD screen, turns the sample pump on, displays the RUN screen,
and begins a combustion test.

• While in the RUN screen, turns the sample pump off, displays the HOLD screen
and the last set of combustion data.

• Displays the HOLD screen while pressing it from most menus.

• Return the display to the HOLD screen while pressing it during the
5 second power down sequence.

• Cancels most operations and displays the previous screen.

• Pressing function keys accepts the corresponding function defined at the bottom
of the display including PRINT, SAVE, MENU, differential pressure ZERO,
differential temperature ZERO, PAGE UP, PAGE DOWN, and CLEAR data.

Operating Tips

1. When an analyzer is brought in from a cold vehicle, let it warm up slowly to minimize
condensation. Temperatures below freezing will not damage the analyzer; however, bringing
a cold analyzer into a warm, humid environment may cause condensate to form inside the
case.

CAUTION: Although the analyzer itself is not damaged by an extremely cold environment,

the electrochemical sensors may be damaged. The O
at approximately -20 °F and the CO sensors at approximately -94 °F. If the analyzer is
exposed to an extremely cold condition, it is strongly suggested that the sensor housings
be examined for hairline cracks. Be aware that a leaking sensor can cause chemical
burns to the skin and possibly damage the PCB assemblies.

2. Ensure that the analyzer is sampling fresh air when turned ON. Pulling a stack-gas sample
through the analyzer during its warm-up period will not damage the analyzer, but it will result
in incorrect sensor readings, and may result in sensor error messages appearing after the
warm-up cycle completes.

Note that flue-gas condensate is acidic and very corrosive. It is important not to allow the

analyzer ’s internal components to come in contact with condensate for long periods of time.

3. Before each use, inspect the filter element of the water-trap / filter assembly. Replace the filter
if it looks dirty.

4. When sampling flue-gas, keep the analyzer above the water-trap, and keep the trap in a vertical
position. This will maximize the effectiveness of the trap and keep liquid from being drawn
directly into the analyzer.

5. When liquid condensate is seen inside the water trap, empty the trap before it becomes full.

6. When storing the analyzer, it’s a good idea to empty the water trap and leave it open to further
dry it out.

7. Calibrate the analyzer every 6 months - 1 year to assure its accuracy

Performing Tests

Make sure that the sample point is before any draft diverter/hood or barometric damper so that the
flue gasses are not diluted and the stack temperature has not been decreased by surrounding air
used to balance the draft.
The sample point should also be as close to the breach area as possible, again, to obtain an accurate
stack temperature. This will also provide a more accurate O
gas stream through joints in sheet metal vent connectors.

When testing atmospheric, forced air heating equipment with a clamshell or sectional heat exchanger
design, test each of the exhaust ports at the top of the heat exchanger. The probe should be inserted
back into each of the exhaust ports to obtain a flue gas sample, before any dilution air is mixed in.

Draf t tests should be taken from a hole drilled in the stack downstream from the draft hood.

Combustion and draft testing fan assist, furnaces/boilers should be
done through a hole drilled in the vent immediately above the inducer
fan. While fan assist equipment operates under a negative draft, it
is good practice to seal the sample hole, high temperature silicone is
generally recommended.
