1.0 INTRODUCTION
1.1 The Fyrite Tech
Available in two models, the Fyrite Tech 50 and 60 are hand-held ana-
lyzers that are designed to calculate the efciency of residential furnaces
and combustion appliances by measuring the stack temperature and the
percent oxygen level in the ue-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.

Measures: Measures:
• Oxygen (O2)
• Stack Temperature • Stack temperature

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 inspection of the appliance should be carried out to ensure its safe operation.

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 ug-gas
stream of the appliance under test. Each analyzer model will continuously
monitor the ue 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.

3.0 SETTING UP THE ANALYZER
3.1 Scope
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 Batteries
Install fresh batteries as described below. Check the analyzer for sufcient
charge prior to each use. Replace the batteries if the low-battery symbol
appears in the lower right corner of the screen. To replace the bat-
teries:
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 compartment,
install four ‘AA’ Alkaline batteries as shown in Figure 3-1.
4. Replace battery cover.

3.3 Connecting the Probe
Connect the probe assembly’s ue-gas hose and thermocouple connector to
the analyzer as follows (see Figure 3-2):
1. Push the ue gas hose onto the analyzer’s GAS inlet tting.
2. Push the ue gas thermocouple into the T-STACK jack
Important: DO NOT force thermocouple connector. The con-
nection tabs are different sizes, allowing the connector to t
in only one way.
Inspect the ue-gas hose for cracks. Replace the hose if it is defective.
Before using the analyzer, check that the Water Trap / Filter is dry and
not dirty. If necessary, dry out the trap and replace the lter element per
Section 5.6.
