Fyrite Pro 1.0 INTRODUCTION 1.1 The Fyrite Pro The Fyrite Pro series of instruments are hand-held analyzers 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.
Fyrite Pro 1.2 Operational Overview Pressing the I/O button turns the analyzer ON. Note that there is a warmup 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.

Fyrite Pro 4.0 OPERATION 4.1 Performing CO and Draft Testing 4.1.1 Analyzer Turn On and Warm Up 1. Connect the probe and make sure that the analyzer is properly set up per Section 3.0. 2. Turn ON the analyzer in fresh air by pressing is I/O button and observe that the following Warm-Up Screens are displayed. These screens show the analyzer’s model number, the unit’s software revision, and finally the remaining warm-up time. If an O2 sensor is installed, then its current output level is also displayed.
Fyrite Pro 4.1.2 Measuring CO (Model 100/105/120/125) 1. Turn ON the analyzer and allow it to warm-up per Section 4.1.1. Important: If the CO channel is set up for auto zero, then the analyzer must be turned ON in fresh air; otherwise, incorrect CO readings will occur. Refer to Section 3.5.3. When the CO channel is set up for manual zero, and if the CO reading is higher than zero when sampling fresh air, then manually zero the CO channel per Section 5.6, Steps 1 thru 4. 2.
Fyrite Pro 4.2 Performing a Combustion Test using the Model 110/120/125 4.2.1 Analyzer Turn On and Warm Up Important: The probe must be at room temperature before performing the following steps. 1. Connect the probe and make sure that the analyzer is properly set up per Section 3.0. 2. Perform one of the following: • Model 110/120 – Before turning ON the analyzer, its probe must be located in the area containing the burner’s combustion-air supply.
Fyrite Pro 4.2.3 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.

Fyrite Pro 4.2.4 Performing a Combustion Efficiency Test 1. After turning ON the analyzer and selecting the appropriate fuel, press the ▲ or ▼ button to display the Stack Temperature & Efficiency Screen (refer to Section 4.13.10). 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. Burner-service procedures can now begin.
Fyrite Pro 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 (Model 100/105/120/125) is set up for Auto Zero (refer to Section 3.5.3), ensure that the analyzer is sampling fresh air when turned ON.
Fyrite Pro 4.4 Using the Backlight The LCD can be read in dimly-lit areas by pressing the LIGHT button. The backlight automatically turns OFF after 10 minutes of keyboard inactivity, but can be turned OFF at any time by again pressing the LIGHT button. 4.5 Using the Probe A rigid stainless steel probe with handle, connected to a flexible hose with integral water-trap / filter can be used to draw a gas sample into the analyzer from the room, grilles, diffusers, and furnace flues.
Fyrite Pro 2. Press the ▼ button once to display the Save Screen. The number shown in this screen represents the memory location (1 thru 10) to which the current test data will be saved. 3. Press ENTER to save the test data and return to the Hold Mode, or press HOLD to return to the Hold Mode without saving. 4.
Fyrite Pro 4.8 Printing Test Data Tip: To avoid printing errors, it is important to select the correct protocol per Section 3.5.8 before saving data. Turn ON the printer.

Fyrite Pro 4.13 Screen Descriptions 4.13.1 Warm-Up Screens As soon as the analyzer is turned ON, a series of Warm-Up Screens are displayed. These screens show the analyzer’s model number (Pro 100/105/110/120/125), the unit’s software revision, and finally the remaining warm-up time counted down from either 10 or 60 seconds. If an O2 sensor is installed, then its current output level is also displayed.
Fyrite Pro 4.13.3 CO & Draft Screen (Model 105/125) The CO reading is a measurement of how much carbon monoxide in ppm is present in the flue-gas stream. Note, however, that the amount of CO displayed may be diluted by secondary air (refer to Section 4.13.12 CO Air Free Screen). The draft display is the difference between the pressure at the analyzer’s “+” port and the pressure at the “–” port when using probe model 24-7266. Front Panel Button Functions: ▲ – Displays next screen (refer to Section 4.
Fyrite Pro 4.13.5 Fuel Screen (Model 110/120/125) The Fuel Screen is displayed after warm-up, and is where an operator chooses which fuel is to be used by the analyzer to calculate combustion efficiency. Pressing the ▲ or ▼ button scrolls the display through the fuel codes. Pressing ENTER selects the displayed fuel and places the analyzer into its Run Mode. Note that the fuel code will be displayed in the top right corner of all screens while in the Run Mode.
Fyrite Pro The CO reading is a measurement of how much carbon monoxide in ppm is present in the flue-gas stream. Note, however, that the amount of CO displayed may be diluted by secondary air (refer to Section 4.13.12 CO Air Free Screen). The O2 reading is the measured percentage of oxygen present in the fluegas stream. Front Panel Button Functions: ▲ – Displays next screen (refer to Section 4.12) ▼ – Displays previous screen (refer to Section 4.
Fyrite Pro 4.13.9 Temperature Differential Screen (Model 125) The Temperature Differential reading is the measured difference between the temperatures being measured by the T-STACK and T-AIR thermocouples. Front Panel Button Functions: ▲ – Displays next screen (refer to Section 4.12) ▼ – Displays previous screen (refer to Section 4.
Fyrite Pro 4.13.11 Ambient Air Temperature Screen (Model 110/120/125) The AMBIENT reading is the combustion-air temperature in either °F or °C that is used for efficiency calculations. This temperature is measured by either the T-AIR thermocouple on a continuous basis ( Model 125), or by the T-STACK thermocouple during start-up (Model 110/120/125). If neither thermocouple is installed when the analyzer is turned ON, then this temperature reading comes from a temperature sensor located inside the analyzer.
Fyrite Pro 4.13.13 Sensor Error Screen (Model 100/105/110/120/125) 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 or the CO & O2 Screen.
