Water heater having a low NOx burner integrated with FVIR platform

摘要

Various embodiments of fuel-fired low NOx water heaters are provided with burners having built-in venturi inlet sections for receiving fuel from a source thereof and combustion air from outside of the water heater. The burners are integrated in various manners with flammable vapor ignition resistance (FVIR) platforms to thereby reduce the tooling costs necessary to provide the water heaters with both lowered NOx emissions and flammable vapor ignition resistance.
