Explanation
Code generally exempts certain appliances such as listed ranges, clothes dryers, and outdoor grills from the sediment-trap requirement, while furnaces, boilers, and water heaters still require one. The trap protects the automatic gas valve on heating appliances from moisture and debris. Always check the specific list in the adopted code and the appliance instructions.
