Connect Flexible Gas Line and Main Supply

What happens here

First, connect one end of the flexible gas line to the T-fitting on the drip leg assembly, ensuring it is properly aligned and hand-tightened before using adjustable pliers for final tightening. Next, connect the other end of the flexible gas line to the gas line section installed in the internal gas valve (from Step 8). Make sure both connections are snug and secure to prevent any leaks.

Goal: Connect the flexible gas line to the newly installed drip leg and the furnace's internal gas line, tightening all fittings for a secure connection.
