    Fyrite Pro 1.0 INTRODUCTION 1.1 The Fyrite Pro The Fyrte Pro seres of nstruments are hand-held combuston effcency analyzers that are desgned for on-demand samplng of resdental furnac- es and applances. 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: Operational Overview

    Fyrite Pro 1.2 Operational Overview Pressng the I/O button turns the analyzer ON. Note that there s a warm- up perod of 60 seconds before the unt can be used for testng. After completon of the warm-up perod, choose a fuel code that corre- sponds 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. 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 keyboard nactvty. The power saver functon s dsabled f the detected O value s less than 17.9%, or for analyzers wth a CO sensor the CO value s more than 50 ppm. Press the I/O button to turn the analyzer OFF. Note that there s a 5 sec- ond delay before the analyzer actually turns OFF, durng whch tme the unt can be kept ON by pressng the eNTeR button. For analyzers that contan a CO sensor, there s a CO purge feature that keeps the analyzer’s...

  • Page 25: 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 125E only) 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 durng ts warm-up perod wll not damage the analyzer, but t wll result n n- correct CO readngs. Also note that a CO sensor error wll occur f the detected CO level s above 50 ppm durng warm-up. • When measurng flue-gas, note that flue-gas condensate s acdc and very corrosve. It s mportant not to allow the analyzer’s nternal com- ponents 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. Refer to Secton 5.8. • 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.

    Fyrite Pro 4.13.11 Sensor Error Screen An O sensor error s dsplayed f the analyzer determnes durng the warm-up cycle that the oxygen sensor’s output s too low for t to be usable. However, n the extreme condton when the O sensor has no output, a sen- sor error wll not occur. Instead, the O readng wll be 0.0 as dsplayed n 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).
