Valve Sit 820 - Natural Gas - 230-0710

Close gas line valve, disconnected all the wires and gas lines, removed the whole platform from the fireplace (easier to work on than from underneath), removed the pilot assembly, removed the valve, cleaned everything, replaced the main valve (be sure to tape/dope the threads to prevent leaks), replaced the pilot assembly with the new, connected the pilot assembly lines and wires to the main valve, replaced the platform, reconnected the main gas line, turned the gas line on and checked for leaks, turned the pilot on, checked again for leaks, switched on/off a few times, reassembled the logs, cleaned glass and cleaned up. Let the fireplace warm up for at least 3 minutes as that is when the leak showed originally throwing flames to the side. Check again.

Removed pilot and gas valve and basically reversed process to replace. Gas valve had to be put on a vice to get last nut off. It works now. you need patience and correct tools.

took pictures, turned off all electrical power, turned off the gas. removed the wires that were attached to the valve. removed the gas lines to the valve.removed the gas fittings form the old valve, cleaned them up with a wire brush.used plumbers tape on the fittings and installed them on the new valve. hooked up the gas lines and then the electric connectors.tested the unit, and used soapy water on the gas fittings to test for leaks. works great.
