1.0 INTRODUCTION
1.1 The Fyrite Tech
Available in two models, the Fyrite Tech 50 and 60 are hand-held analyzers that are designed to calculate the efficiency of residential furnaces
and combustion appliances by measuring the stack temperature and the
percent oxygen level in the flue-gas stream.
While both analyzers are capable of combustion testing, the Fyrite Tech
60 has the added capability of measuring carbon monoxide and calculating
CO air-free, and also has the capability of sending combustion test data to
an optional printer via an infrared port using either HP or IrDA protocol.

1.2 Operation Overview
Pressing the I/O button turns the analyzer ON. Note that there is a 60 second warm-up period which must elapse before the analyzer can be used.
After warm-up is complete, choose the fuel code that corresponds to the
fuel being burned by the appliance being tested. Then press the ENTER
button to place the analyzer into its Run Mode and begin the combustion
testing process.
Begin testing by inserting the analyzer’s probe tube into the flug-gas
stream of the appliance under test. Each analyzer model will continuously
monitor the flue gas and display measured and calculated values that
are relative to the combustion process. These values are displayed on the
analyzer’s LCD, and are chosen for display by pressing the Increment ( )
and Decrement ( ) buttons.
The Fyrite Tech 60 has the capability of sending the current combustion
test to an optional printer by pressing the HOLD button twice.
Pressing the HOLD button during a test will freeze all measured and
calculated values at their current values. Pressing the ENTER button
resumes testing.
A backlight enables an operator to read the display in dimly-lit areas.
Pressing the LIGHT button turns the backlight ON and OFF. The backlight
will automatically turn OFF after 10 minutes of keyboard inactivity.
A power-saver function will shut the analyzer OFF after 20 minutes of
keyboard inactivity. Note, however, that the power-saver function is disabled if the detected O2 value is less than 17.9% or the CO value is more
than 50 ppm.
Press the I/O button to turn the analyzer OFF. Note, that there is a 5 second delay before the analyzer actually turns OFF, during which time the
unit can be kept ON by pressing the ENTER button.
If the analyzer is turned OFF while a high level of CO is still present
within the unit, the pump remains running and the unit will not turn OFF
until the detected CO level drops below 50 ppm.

4.0 OPERATION
4.1 Performing a Test
4.1.1 Analyzer Turn On and Warm Up
Important: The probe must be at room temperature before
performing the following steps. The temperature measured
by the probe during warm up is the combustion-air temperature used by the analyzer for efficiency calculation purposes.
1. Make sure that the analyzer is properly set up per Section 3.0.
2. During warm-up, the analyzer’s probe must be located in the area
containing the burner’s combustion-air supply. If the burner is using room air, simply place the probe within the room. In the case
of a high-efficiency furnace where combustion air is drawn in from
an outside source, place the probe within that area with the burner
operating. After the probe is properly positioned, turn ON the analyzer by pressing its I/O button.
3. Wait for the analyzer to complete its 60 second warm-up period;
after which, the Fuel Screen is displayed. If errors were detected
during warm-up, the Sensor Error Screen will be displayed. If this
occurs, refer to Section 4.8.9 to correct the cause of the error.
4.1.2 Selecting a Fuel
1. With Fuel Screen displayed, use the or button to step through
the fuel codes until the proper fuel is selected. The analyzer defaults to the most recently selected fuel.
F1 = Natural Gas
F2 = Oil #2
F3 = LPG
F4 = Kerosene
2. Press the ENTER button to select the displayed fuel code;after
which, the analyzer enters the Run Mode.
4.1.3 Manual Zero of the CO Channel (Model 60 only)
If the CO channel is set up for manual calibration (refer to Section 3.5.3),
and if the CO reading shows a value other than zero in fresh air, then before proceeding with a test manually zero the CO channel per Section 5.5.
Instruction 0024-9435

Fyrite Tech
4.1.4 Sampling Point
Forced Air Furnace – When testing atmospheric burner or gravity
vented, 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.
Hot Water Tank – Domestic hot water tanks with the ‘bell’ shaped draft
diverter on top can be accurately tested by inserting the probe tip directly
into the top of the fire tube below the diverter.
80% Efficiency Fan Assist or Power Vented – Combustion testing of
fan assist or power vented, furnaces/boilers should be done through a hole
drilled in the vent immediately above the inducer fan.
90% Efficiency Condensing – Condensing furnaces/boilers can be tested
through a hole drilled in the plastic vent pipe (when allowed by the manufacturer or local authority of jurisdiction) or taken from the exhaust termination.
Atmospheric or Gravity Vented Boiler – Boilers, which have a ‘bell’
shaped draft diverter directly on top, should be tested directly below the
diverter through a hole drilled in the vent connector.

4.1.5 Performing a Combustion Efficiency Test
1. After turning ON the analyzer and selecting the appropriate fuel,
press the and button until the Stack Temperature & Efficiency
Screen (refer to Section 4.8.7) is displayed.
2. Position the probe in the flue-gas stream to obtain the hottest
"STACK" reading. Locating the highest stack temperature is very
important for accurate efficiency calculations.
3. You can now begin burner-service procedures. Use and buttons during a test to scroll through the analyzer’s other display
screens (refer to Section 4.7). The analyzer readings will update
continuously showing changes in burner performance.
4. Pressing the HOLD button freezes all readings and stops the pump.
The and buttons can now be used to scroll through the displays and view all test values at the moment the HOLD button was
pressed. Pressing ENTER restarts the pump and resumes testing.
4.1.6 Printing Test Results (Model 60 only)
During a combustion efficiency test, the current test results can be sent to
a printer as follows:
1. Turn ON printer.
TIP: Refer to the printer's instruction manual for detailed operating
information. If not already done, set up the printer for 9600 baud,
DTR handshaking, and the same protocol as the analyzer (HP or
IrDA). Refer to Section 3.5.7 Selecting Printer Protocol.
2. Align the printer with the top of the analyzer as shown in Figure
4-1.
3. Begin printing by doing one of the following:
- If the pump is running, press the HOLD button twice.
- If the display has been previously frozen by pressing the HOLD
button, press the HOLD button only once.

4.1.7 Ending a Combustion Test
WARNING! Burn Hazard. Do not touch the probe after
removing it from the stack. Allow the probe to cool before
handling (about 5 minutes).
1. Remove probe from flue-gas stream.
2. Allow the pump to run until all combustion gases are flushed from
the analyzer as indicated by the O2 reading returning to 20.9%.
4.1.8 Turning OFF the Analyzer
After the analyzer has been purged with fresh air, turn it OFF by pressing
the I/O button. The unit will count down from 5 before turning OFF. Pressing the ENTER button, however, will stop the count down and keep the
analyzer turned ON.
4.2 CO Purge During Turn OFF (Model 60 only)
If the detected CO level is above 50 ppm when the analyzer is turned OFF,
the unit will remain ON with its pump running and display "PurG CO."
The countdown from 5 will not begin until the CO level drops below 50
ppm.
Although not recommended for everyday use, the purging process can be
bypassed by pressing the I/O button a second time.

4.3 Operating Tips
• 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.
• If the CO channel (Fyrite Tech 60) is set up for Auto Zero (refer to Section 3.5.3), ensure that the analyzer is sampling fresh air when turned
ON. Pulling a flue-gas sample through the analyzer during its warm-up
period will not damage the analyzer, but it will result in incorrect CO
readings. Also note that a CO sensor error will occur if the detected CO
level is above 50 ppm during warm-up.
• For analyzers that are used to measure flue-gas, note that flue-gas
condensate is acidic and very corrosive. It is important not to allow the
analyzer's internal components to become soaked in condensate for long
periods of time.
• Before each use, inspect the filter element of the water trap / filter assembly. Replace the filter if it looks dirty.
• 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 condensate from being drawn directly into the
analyzer.
• When liquid condensate is seen inside the water trap, empty the trap
before it becomes full. Refer to Section 5.6.
• It is recommended that the analyzer be purged after taking a flue-gas
measurement before turning it OFF. Once the probe is removed from the
stack, disconnect the hose assembly from the bottom of the analyzer and
let the pump run for 10 minutes or so to completely remove any remaining flue gases and dry any condensate from inside the sensor chamber.
• When storing the analyzer, it's a good idea to empty the water trap and
leave it open to further dry it out.
• Calibrate the analyzer every 6 months to ensure its accuracy.

Fyrite Tech
4.8.9 Sensor Error Screen
An O2 sensor error is displayed if the analyzer determines during the
warm-up cycle that the oxygen sensor’s output is too low for it to be usable.
However, in the extreme condition when the O2 sensor has no output, a sensor error will not occur. Instead, the O2 reading will be 0.0 as displayed in
the O2 Screen (Model 50) or the CO & O2 Screen (Model 60).
When the CO channel (Model 60 only) is set up for Auto Zero (refer to
Section 3.5.3), a CO sensor error will occur if the detected carbon monoxide level is above 50 ppm during the warm-up cycle. Note that if the CO
channel is set up for manual calibration, the analyzer does not auto-zero
the CO sensor during warm-up, and thus does not generate a CO sensor
error when the analyzer is turned ON in an atmosphere containing a high
background level of CO.
Do the following before replacing a suspected spent or defective sensor:
1. Turn OFF the analyzer and turn it back ON in an area of fresh air
(containing 20.9% O2 and no CO).
2. Perform the Oxygen Sensor Zero procedure (Section 5.4) and, if applicable, the CO Sensor Zero & Calibration procedure (Section 5.5).
3. If Steps 1 & 2 do not eliminate the error condition, replace sensor(s)
(refer to Sections 5.7 or 5.8).
