Flame rod and ignitor maintenance... Continuing our Navien, Inc combi service and maintenance clips, we focus on the flame sensor and ignitor portion. A clean flame sensor will prevent flame failure leading to nuisance service calls. Also ensuring our ignitors are clean and well grounded will help our gas fully ignite. #hvac #hvacr #hvacsystem #hvaclife #combiboiler #boilermaintenance #boiler #hydronics #hydronicsheating #waterheater #tanlkesswaterheater #hvacsystem #hvactroublshooting #hvactrai
