My current device is bad, it reads Dexen 6003 NAT 5.0" WC max 1/2 PSI. Is this the proper replacement?
By Collin C. - NFI Master Hearth Professional on January 14, 2014

This is indeed the same valve that you currently have now and will offer a direct fit replacement.

How do I restart the pilot light on a Dexen 6300M fireplace?
By eFireplaceStore on November 11, 2014

Your model of gas valve should have a small pointer or arrow cast into the aluminum body, which is pointing toward the black control knob. With a lighter in hand, rotate the control knob until the "pilot" position is lined up with the arrow. Ignite the lighter and hold it just above the flat hood on the pilot assembly, while then pushing in and holding the black control knob. Once the pilot flame begins to light, you can remove the lighter from the pilot area. Continued holding the black control knob down for approximately 30 seconds. At this point, you should be able to release the knob and the pilot will stay lit. Allow the pilot to warm and stabilize for a couple of minutes. You can then rotate the control knob to the "on" position and the main burner should ignite.

My pilot light works but I can't get the rest of the system to light. Do you know what might be wrong?
By Collin C. - NFI Master Hearth Professional on November 12, 2013

If the system uses a millivolt valve, there is a simple test that can be performed to check functionality of the gas valve itself. With the pilot lit and the gas valve knob turned to the "on" position, use a short jumper wire, 18 gauge or better, to jump between the "THTP" and "TH" terminals on the end of the valve. If the valve lights, there is a defective switch, remote receiver, or limit switch causing the problem. If the valve does not light, it could be stuck or the thermopile is no longer functional. Please advise as to your findings. I will be happy to assist you further.
