1.0 INTRODUCTION
1.1 The Fyrite Pro
The Fyrite Pro series of instruments are hand-held an a lyz ers that are
designed for on-demand sampling of residential furnaces and appliances.
The more advanced models can also to used to check combustion efficiency
by measuring the stack temperature and the percent oxygen level in the
flue-gas stream.
The Fyrite Pro is completely upgradable from the very simple Model 100
that measures only carbon monoxide, to the Model 125 that measures
carbon monoxide (CO), oxygen (O
air temperature, stack temperature, and combustion air temperature, as
well as calculating combustion efficiency, excess air, carbon dioxide (CO
differential temperature, and CO air free.

This manual contains information on all models of the Fyrite Pro. Please
disregard any information that does not pertain to your model.
WARNING S!
This analyzer should not be used on a continuous basis.
This analyzer does not have an audible alarm, and should
not be used as a safety device.
Except for battery replacement, this analyzer should only be
opened and ser viced by au tho rized personnel.
When testing an appliance, a full visual in spec tion of the
appliance should be carried out to ensure its safe op er a tion.
CAUTION!
When the instrument is used in an ineffi cient furnace or
boiler application where there is a high emission of soot,
probe sample fi lter may become clogged. Check fi lter before
every use to confi rm that it is clean for use or replace with
a new fi lter. To prevent this from occurring, a smoke test
should be performed before operating under such conditions
to ensure that the furnace is burning at a level appropriate
for the use of this instrument.

1.2 Operational Overview
Pressing the I/O button turns the analyzer ON. Note that there is a warm-
up period of either 10 or 60 seconds, dependent on the analyzer’s model and
setup, that must elapse before the analyzer can be used.
When using the analyzer to just measure CO or draft, insert the analyzer’s probe into the flue-gas stream of the appliance under test and begin
testing. The measured values of draft and/or CO will appear on the analyzer’s LCD.
For models that calculate combustion efficiency, choose a fuel code that corresponds to the fuel being burned by the appliance being tested, and then
press the ENTER button to place the analyzer into its Run Mode. Begin
testing by inserting the analyzer’s probe tube into the flue-gas stream
of the appliance under test. The analyzer will monitor the flue gas and
display measured and calculated values that are relative to the combustion
process. These values are dis played on the analyzer’s LCD, and are chosen
for display by pressing the In cre ment (▲) and Dec re ment (▼) but tons.
Pressing the HOLD button during a test will freeze all measured and calculated values at their current levels. Pressing the ENTER button resumes testing.
For analyzers with memory, pressing the HOLD button twice during a
test will display the Print/Memory Menu Screen. Using the ▲▼ and
ENTER buttons the operator can choose to print the current readings,
save the current readings in memory, recall and view saved readings from
memory, clear all the memory, or print all saved readings.
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 min utes of keyboard inactivity. For models with an O
saver function is dis abled if the detected O
and CO sensor, however, the power
2
value is less than 17.9% or the
2
CO value is more than 50 ppm.
Press the I/O button to turn the analyzer OFF. Note that there is a 5 sec-
ond delay before the analyzer actually turns OFF, during which time the
unit can be kept ON by pressing the ENTER button. For analyzers that
contain a CO sensor, there is a CO purge feature that keeps the analyzer’s
pump running until the measured CO level drops below 50 ppm.

3.0 SETTING UP THE ANALYZER
3.1 Preliminary Steps
Before using the analyzer . . .
• Check batteries (Section 3.2)
• Connect probe to analyzer (Section 3.3)
• Check setup (Section 3.5)
3.2 Checking & Replacing the Bat ter ies
Install fresh batteries as described below. Check the analyzer for sufficient
charge prior to each use. Replace the batteries if the low-battery symbol
appears in the lower right corner of the screen. To re place the bat-
ter ies:
1. Remove battery cover from back of analyzer.
2. If old batteries are installed, remove them and properly discard.
3. Observing the polarity markings inside the battery com part ment,
install four ‘A A’ Al ka line bat ter ies as shown in Fig ure 3-1.
4. Replace battery cover.
Remove battery cover by
pushing down on cover
and sliding it outward

3.3 Connecting the Probe Hose and
Thermocouple
The analyzer’s model number determines which hose and thermocouple
connections are made at the bottom of the unit. Perform the following steps
as required by your particular analyzer model (see Figures 3-2A thru D):
1. Push the probe’s sample-gas hose onto the GAS inlet fitting.
2. Push the probe’s draft hose onto the “+” pressure fitting.
3. Push the probe’s thermocouple into the T-STACK jack
Important: DO NOT force the thermocouple connector into
its jack. The con nec tion tabs are dif fer ent sizes, allowing the
connector to fit in only one way.
4. Push the optional room-air/primary-air thermocouple into the
T-AIR jack.
Inspect the flue-gas hose for cracks. If a hose is defective, replace the entire probe assembly.
Before using the analyzer, check that the Water Trap / Filter is dry and
not dirty. If necessary, dry out the trap and replace the filter el e ment per
Section 5.8.
