    Fyrite Pro 1.0 INTRODUCTION 1.1 The Fyrite Pro The Fyrte Pro seres of nstruments are hand-held analyzers that are desgned for on-demand samplng of resdental furnaces and applances. The more advanced models can also to used to check combuston effcency by measurng the stack temperature and the percent oxygen level n the flue-gas stream. The Fyrte Pro s completely upgradeable from the very smple Model 100 that measures only carbon monoxde, to the Model 125 that measures carbon monoxde (CO), oxygen (O ), draft, dfferental pressure, ambent ar temperature, stack temperature, and combuston ar temperature, as well as calculatng combuston effcency, excess ar, carbon doxde (CO dfferental temperature, and CO ar free. Ths manual contans nformaton on all models of the Fyrte Pro. Please dsregard any nformaton that does not pertan 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.

  • Page 8: OperatOnal OvervEw

    Fyrite Pro 1.2 Operational Overview Pressng the I/O button turns the analyzer ON. Note that there s a warm- up perod of ether 10 or 60 seconds, dependent on the analyzer’s model and setup, that must elapse before the analyzer can be used. When usng the analyzer to just measure CO or draft, nsert the analyz- er’s probe nto the flue-gas stream of the applance under test and begn t estng. The measured values of draft and/or CO wll appear on the ana- lyzer’s LCD. For models that calculate combuston effcency, choose a fuel code that cor- responds to the fuel beng burned by the applance beng tested, and then press the eNTeR button to place the analyzer nto ts Run Mode. Begn testng by nsertng the analyzer’s probe tube nto the flue-gas stream of the applance under test. The analyzer wll montor the flue gas and dsplay measured and calculated values that are relatve to the combuston process. These values are dsplayed on the analyzer’s LCD, and are chosen for dsplay by pressng the Increment () and Decrement () buttons. Pressng the hOlD button durng a test wll freeze all measured and calculat- ed values at ther current levels. Pressng the eNTeR button resumes testng. For analyzers wth memory, pressng the hOlD button twice durng a test wll dsplay the Prnt/Memory Menu Screen. Usng the  and eNTeR buttons the operator can choose to prnt the current readngs, save the current readngs n memory, recall and vew saved readngs from memory, clear all the memory, or prnt all saved readngs. A backlght enables an operator to read the dsplay n dmly-lt areas. Pressng the lIGhT button turns the backlght ON and OFF. The backlght wll automatcally turn OFF after 10 mnutes of keyboard nactvty. A power saver functon wll shut the analyzer OFF after 20 mnutes of key- board nactvty. For models wth an O and CO sensor, however, the power saver functon s dsabled f the detected O...

  • Page 29: OperatNg TPs

    Fyrite Pro 4.3 Operating Tips • When an analyzer s brought n from a cold vehcle, let t warm up slowly to mnmze condensaton. Temperatures below freezng wll not damage the analyzer; however, brngng a cold analyzer nto a warm, humd envronment may cause condensate to form nsde the case. • If the CO channel (Model 100/105/120/125) s set up for Auto Zero (refer to Secton 3.5.3), ensure that the analyzer s samplng fresh ar when turned ON. Pullng a flue-gas sample through the analyzer dur- ng ts warm-up perod wll not damage the analyzer, but t wll result n ncorrect CO readngs. Also note that a CO sensor error wll occur f the detected CO level s above 50 ppm durng warm-up. • For analyzers that are used to measure flue-gas, note that flue-gas condensate s acdc and very corrosve. It s mportant not to allow the analyzer’s nternal components to become soaked n condensate for long perods of tme. • Before each use, nspect the flter element of the water-trap / flter as- sembly. Replace the flter f t looks drty. • When samplng flue-gas, keep the analyzer above the water-trap, and keep the trap n a vertcal poston. Ths wll maxmze the effectve- ness of the trap and keep lqud condensate from beng drawn drectly nto the analyzer. • When lqud condensate s seen nsde the water trap, empty the trap before t becomes full. Refer to Secton 5.8. • It s recommended that the analyzer be purged after takng a flue-gas measurement before turnng t OFF. Once the probe s removed from the stack, dsconnect the hose assembly from the bottom of the analyz- er and let the pump run for 10 mnutes or so to completely remove any remanng flue gases and dry any condensate from nsde the sensor chamber. • When storng the analyzer, t’s a good dea to empty the water trap and leave t open to further dry t out. • Calbrate the analyzer every 6 months to ensure ts accuracy.

The hose and probe assembly can be detached from the analyzer when the operator desres to sample wthout the probe. 4.6 Saving Test Data in Memory (Model 105/110/120/125) Up to 10 ndvdual sets of test data can be saved n memory as follows: Note: When memory is full, the next reading saved will over- write the oldest reading.

    Screen or the CO & O Screen. Tip: To avoid O errors from occurring, consider replac- ing the O sensor when its output level drop below 100 as displayed during warm-up (refer to Section 4.13.1). When the CO channel s set up for Auto Zero (refer to Secton 3.5.3), a CO sensor error wll occur f the detected carbon monoxde level s above 50 ppm durng the warm-up cycle. Note that f the CO channel s set up for manual calbraton, the analyzer does not auto-zero the CO sensor durng warm-up, and thus does not generate a CO sensor error when the analyzer s turned ON n an atmosphere contanng a hgh background level of CO.
