Gas tankless water heaters rely on an electronic spark igniter to light the gas burner and a flame rod sensor to prove flame existence via micro-amp current detection. Carbon buildup, moisture, or thermal oxidation on these delicate rods will cause immediate burner shutdown within 3 seconds of lighting (causing Error Code 11 or 12). Our technicians in New Kingstown, Pennsylvania clean, adjust, or replace igniter and flame rod assemblies to ensure reliable burner ignition every time.
