Abstract
A gas supply coupling for a water heater incorporating a shield to close the opening to the combustion chamber. The coupling includes a supply tube, a connector extending through the shield and a gas supply line detachably connected to the connector. The connector is staked to the shield to prevent disassembly requiring that the entire coupling be removed from the combustion chamber prior to disassembly. The gas supply line includes a threaded fastener having a unique exterior configuration requiring a specialized tool for separation from the connector.
