Gas tankless water heaters require specialized direct-vent technology—either concentric metal venting for non-condensing units or sealed Schedule 40 PVC/CPVC/PP venting for condensing models. Vent pipe sags, loose joints, blocked intake terminations, or improper slope cause dangerous exhaust backpressure or liquid condensate traps that trigger Code 10/90 lockouts. Our venting experts in Bridgeview, Illinois repair vent lines, clear blockages, and ensure complete compliance with local building codes.
