What it is
The gas valve outlet adaptor is a Navien component that connects the outlet of the gas valve to the appliance's gas train on NPE-AWE and NPE-SWE series units. It forms the sealed joint at the gas valve outlet, so correct seating and thread condition are essential to safe gas-tight operation. It is supplied under Navien part number 20018430A.
