Abstract
An apparatus and method for relieving an ignition pulse that may be created at burner ignition in a gas-fired appliance. The burner is located in a combustion chamber forming part of the appliance such as a water heater. A port for admitting air into the combustion chamber is provided and sufficiently sized to relieve an ignition pulse if created upon burner ignition. The air opening is overlaid with an element made from a material that contains a plurality of small openings and is formed into a cup-shaped configuration so that the total area of the material, including both open and non-open areas is substantially greater than the air opening. The port defines an opening for admitting secondary air into the combustion chamber for some applications. The element that overlies the opening may be constructed from one or more layers of a wire mesh material.
