1.0 INTRODUCTION
1.1 The Fyrite Tech
Available in two models, the Fyrite Tech 50 and 60 are hand-held ana -
lyze r s that are designed to calculate the effi c i ency of resi d ential furnaces
and combustion appliances by measuring the stack temperature and the
percent oxygen level in the fl u e-gas stream.
While both analyzers are cap a b l e of combust i on testing, the Fyrite Tech
60 has the added capability of meas u ring CO, calculating CO air-free, and
calculating the ratio of CO/CO2.

• Oxygen (O2)• Oxygen (O2)
• Stack Temperature (TA) • Stack temperature (TA)

WARNINGS!
This analyzer is not intended to be used on a continuous
basis.
The analyzer does not have an audible alarm, and is not
intended to be used as a safety device.
Except for battery replacement, this analyzer should only be
opened and serviced by authorized personnel.
When testing an appliance, a full visual ins p ection of the ap-
pliance should be carried out to ensure its safe ope r a t ion.

1.2 Operation Overview
Pressing the I/O button turns the analyzer ON and OFF. Note that there is
a 60 second warm-up period and a 5 second delay before the analyzer turns
OFF, during which time the unit can be kept ON by pressing the ENTER
button.
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 Inc r ement (▲)
and Decrement (▼)buttons.
Pressing the HOLD button during a test will freeze all measured and
calculated combustion parameters 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. The power saver function, however, is disabled if the
detected O2value is less than 17.9% or the CO value is more than 50 ppm.
