For more guidance, like how to troubleshoot your boiler, read on! Check and correct damper motor end switch wiring. Additional Actions: The Genisys Primary Control may lock out for: For more possible causes, see the “Troubleshooting an Oil Burner” tech bulletin. Clock firing rate and adjust gas pressure regulator for higher pressure. This understanding is important to properly troubleshoot hot water boiler problems, which may occur as a result of an issue with an expansion tank. Grayfurnaceman Furnace Troubleshoot and Repair This site is dedicated to understanding the design, installation and repair of all types of furnaces, old or new. So how do you do this? They are caused by changes in fuel properties (utilities change gas properties in response to available supplies and outdoor temperature), air density changes (barometric pressure, temperature, moisture content), and boiler draft changes (outdoor temperature and wind conditions). If O2 (CO2) changes exceed 1% look for mechanical problems with fuel pressure regulation, draft control, or the burner’s blower and damper systems. All people in the building should exit it. Check and correct POC switch, adjustment and wiring. Check and correct fuel supply, air damper settings, blower wheel and motor, furnace draft. Generally, heat supply should be introduced gradually. At this point, you’ll need to troubleshoot or call a professional. This article was co-authored by our trained team of editors and researchers who validated it for accuracy and comprehensiveness. 120v is present at (L1 to L2) and (Limit to L2) of the Genisys Primary Control. This article was co-authored by our trained team of editors and researchers who validated it for accuracy and comprehensiveness. Also verify there is 120v at L1 to L2 and Limit to L2. Reddish blue flames could indicate higher than normal firing rate, or normal firing in a refractory lined chamber. Check and correct electrical power supply, re-set flame safeguard. To start a boiler, first make sure that you closely follow the safety procedures in your instruction manual for a safe start up. References. This guide is for Oil Burners using a GeniSys Control. It is recommended that, when possible, a continuous oxygen meter be installed in the feedwater system to detect oxygen intrusions. If less O2 (more CO2), check and correct:  adequate air supply to boiler room, boiler furnace pressure, firing rate (preferably by clocking a meter, but also compare to data in burner manual), calibration of analyzer, burner head selection and setting. Should you smell gas, don’t turn on anything (including phones or light switches), evacuate the building, and call the gas company for instructions. Always use properly calibrated instruments to set combustion. Boiler vs Furnace - Understanding Efficiency Ratings. The basic wiring schematics are located in the appropriate burner’s manual. When the limit string is complete, 120v is sent from terminal 5 of the controller subbase to the blower motor. Pronounced trumpet – treat as rumble or roar. When the reset light goes out, release the button. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/1\/10\/Start-a-Boiler-Step-1.jpg\/v4-460px-Start-a-Boiler-Step-1.jpg","bigUrl":"\/images\/thumb\/1\/10\/Start-a-Boiler-Step-1.jpg\/aid8744318-v4-728px-Start-a-Boiler-Step-1.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"
