Gas tankless water heaters require category IV stainless steel or special schedule 40 PVC/CPVC/PP concentric venting to vent high-temperature flue gases safely outdoors. Loose pipe joints, incorrect vent pitch, or bird nests blocking termination caps trigger severe pressure safety codes (Code 90 or Code 10) in Justice, Illinois. Our venting specialists inspect flue gas runs, reseal exhaust collars, replace damaged termination caps, and fix condensation slope angles.
