Abstract
A gas-fired combustion apparatus includes a burner disposed in a substantially sealed combustion chamber and a permeable flexible member arranged to suppress pressure fluctuations within the combustion chamber while concurrently providing for intake of combustion air and restriction of particulate which may interfere with burner operation and increase the risk of ignition of flammable vapor remote of the combustion chamber. The permeable flexible member forms a portion of the combustion chamber wall and is displaceable to provide volume changes. Water heater applications of the burner apparatus are illustrated.
