1.0 INTRODUCTION

1.1 The Fyrite Pro

The Fyrite Pro series of instruments are hand-held combustion efficiency

analyzers that are designed for on-demand sampling of residential furnac-

es and appliances.

This manual contains information on all models of the Fyrite Pro. Please

disregard any information that does not pertain to your model.

WARNINGS!

This analyzer is not intended to be used on a continuous

basis.

This 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.

Instruction 24-9388

Fyrite Pro

1.2 Operational Overview

Pressing the I/O button turns the analyzer ON. Note that there is a warm-

up period of 60 seconds before the unit can be used for testing.

After completion of the warm-up period, choose a fuel code that corre-

sponds 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 displayed on the analyzer’s LCD, and are chosen

for display by pressing the Increment ()and Decrement ()buttons.

Pressing the HOLD button during a test will freeze all measured and calculat-

ed values at their current levels. Pressing the ENTER button resumes testing.

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 minutes of

keyboard inactivity. The power saver function is disabled if the detected O2

value is less than 17.9%, or for analyzers with a CO sensor the 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.

Non-Condensing

Instruction 24-9388

Fyrite Pro

Power Requirements ........................ Four disposable ‘AA’ Alkaline bat-

teries (an optional AC adapter is

available that eliminates the need

for batteries)

Operating Time (using batteries) ... Up to 18 hours continuous (pump

running and backlight off)

Warm Up Time ................................... 60 seconds

Memory ............................................... Up to 10 sets of readings can be

saved in memory. When memory

is full, the next reading saved will

overwrite the oldest reading.

Display ................................................. 4 Digit, 2 Line, 7-segment Liquid

Crystal Display

Front Panel Controls ....................... Six push button switches

(Refer to Section 3.4)

Accuracy:

• Oxygen............................................. ±0.3% O2with a typical flue gas

concentration of CO2

• Carbon Monoxide ............................ ±5% of reading or ±10 ppm, which-

ever is greater*

• Flue Gas Temperature.................... ±2 °C between 0 & 124 °C

(±4 °F between 32 & 255 °F)

±3 °C between 125 & 249 °C

(±6 °F between 256 & 480 °F)

±4 °C between 250 & 400 °C

(±8 °F between 481 & 752 °F)

• Second Thermocouple Channel ...... ±2 °C between 0 & 100 °C

(±4 °F between 32 & 212 °F)

• Ambient Temperature..................... ±2 °C between 0 & 40 °C

(±4 °F between 32 & 104 °F)

• Draft ................................................ ±1% of reading or ±0.05 mB

(±0.02 inWC), whichever is greater

* Tighter CO accuracy in the lower ranges, up to ±2 ppm, may be

attained if a lower range calibration gas (e.g. 100 ppm CO) is used.
