Abstract
A power vented, gas fired water heater has a main gas burner disposed within a combustion chamber partially bounded by an arrestor plate having a spaced series of flame quenching combustion air inlet openings therein. To provide for a “soft” ignition of extraneous flammable vapors entering the combustion chamber and to limit the build-up of unignited flammable vapors within the combustion chamber during non-demand periods of the water heater, a non-flame type ignition device is disposed within the combustion chamber and operated at least intermittently during such non-demand periods.
