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
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.
Boilers, which have a ‘bell’ shaped draft diver ter directly on top,
should be tested directly below the diverter through a hole-drilled
in the vent connector.
Should draft tests below the diverter measure insufficient draft
levels, an additional test should be performed above the diverter to
determine if the reason for insufficient draft is related to a chimney
problem or a draft hood problem.
It is also a good idea to test any areas with openings that provide a
path for combustion air to be introduced to the flame. These areas
provide a path where flue gases can potentially be exhausted.
With forced air systems this area is generally limited to
immediately in front of the burners while many styles of
boilers allow secondary combustion air to also be drawn
in from all around the base of the cabinet.
Gas and oil fired power burners should be tested up
stream from the barometric, as close to the breech area
as possible.
While stack draft may be an impor tant measurement,
fuel oil and gas fired power burners require draft control
over the fire to maintain a proper and controlled intake
of combustion air.
1. In the MAIN MENU highlight the DIAGNOSTICS MENU and select ENTER. This screen
allows you to look at the total run times for the instrument, check O2 and CO sensor status
and thermocouple output.
Turning Off the Analyzer
1. Before turning off the instrument, disconnect the hose and probe assembly and check the
water trap for moisture, empty if necessary. Allow the instrument to continue to pump
fresh air for a few minutes to make sure all water and flue gases are purged from the internal
components.
2. Press and hold down the POWER button for approximately 2 seconds at which time the display
will read PURGING SENSORS, then count down for 5 seconds and power off.
3. You can also opt to set the instrument up to do a longer post purge period by going to the
MAIN MENU, SETUP and scrolling down to the POST-PURGE PERIOD and pressing the
ENTER button. The default time from the factory is 5 seconds; you can also select NONE
(We recommend against no purge), 1 minute, 5 minutes or 10 minutes.
Calibration and Maintenance: IMPORTANT
1. Before performing any calibration procedure, ensure that fresh batteries are installed or use
the optional AC power adapter. Also, ensure that the analyzer is at room temperature and
will be sampling fresh air when turned ON.
IMPORTANT: To maintain accuracy, the standards used must be at least four times as
ac cu ra te as t he st ated ac cu rac y o f the Fy ri te® INSIGHT. (See INSIGHT instruction manual
P/N 24-9460)
The Fyrite® INSIGHT utilizes Bacharach’s new Smart Sensor technology for its CO sensors.
B-Smar t™ sensors are market with a 10-Digit Calibration Code that can be entered in the
B-Smart™ calibration screen. Once the B-Smar t™ code is entered and the sensor is installed
the CO channel is calibrated.
Benefits of Smart Sensors:
a. New sensors can be installed without needing to be calibrated.
b. Sensors can be pre-calibrated and installed when needed.
c. Sensors can be moved from one analyzer to another.
d. Sensors can be sent in for calibration without sending in the entire instrument.
The smart sensors should be calibrated every
6 months to 1 year to assure that the analyzer
con tinues to meet its published accuracy
specifications. For details surrounding the
B- Smar t™ re-calibr atio n progr a m, go to
MyBacharach.com\bsmart. For additional

Performing a Combustion Test Using the Fyrite® INSIGHT
After the analyzer is powered up and the appropriate
fuel selected, insert the probe in the proper sample
location for the equipment being tested. Contact
the manufacturer of specific equipment or consult
the manufacturers’ literature to determine the
proper sample locations for combustion/carbon
monoxide, stack temperature and draft tests. The
following are recognized as generally accepted
locations for testing heating equipment, consult
with the manufacturer of specific equipment to
make cer tain.
The measuremen t for gases and temperature
should be taken at the same point. Typically, this
is done by selecting a sample location ‘upstream’
from the draft diverter/hood, barometric control
or any othe r openi ng, whi ch allows room air
to enter and dilute flue gases in the stack. In
larger installations it may also be necessary to
extr act a number of sample s from inside the
flue to determine the area of greatest flue gas
concentration. Another common practice is to
take the flue gas sample from the ‘Hot Spot’ or the
area with the highest temperature.
Co nden sing furnac e s / b oile r s can be te s ted th r ough a
hole drilled in the plastic vent pipe (when allowed by the
manufacturer or ‘local authority of jurisdiction) or taken from
the exhaust termination.
In order to obtain an accurate Steady State Efficiency reading,
an auxiliary thermocouple must be inserted in the combustion
air intake so that a true net stack temperature is used in the
calculation.
It is important to remember that the vent system on these units
operates under a positive pressure. As a result, any holes in
the vent need to be sealed.
Domestic hot water heaters with the ‘bell’ shaped draft
diverter on top can be accurately tested by at taching a
section of copper tubing to the probe or using a flexible
probe which is then inserted directly into the top of the
fire tube below the diverter.
Another common practice is to insert the probe in the hole
drilled for the draft test, direct it down and push it below
the level of the draft hood.
