Boiler combi mini series... Over the next couple of months, I will be sharing some Navien, Inc combi boiler install, maintenance and service tips. We start here by showing off the fire tube heat exhanger and how it functions. Fire tube heat exchangers can put less strain on pumps as we're not dealing with smaller passages that we see on water tube heat exhangers. If you'd like to watch the entire walk through, it's on the HVAC Know It All YouTube channel and added to my story. Or link in the com

Ignition transfer troubleshooting... Continuing our series on Navien troubleshooting and maintenance, we perform some basic troubleshooting on this combi unit NFC-250/175H. Ignition issues are simple to troubleshoot relatively speaking. If we have no power to our ignition transformer on a call, it could be a wiring issue or control board issue. If we have power to our transformer but no spark, most likely our transformer must be replaced. #hvac #hvactroubleshooting #combiboilertroubleshooting #c
