RE: It should be OK and a great buy
Contrary to what "takeahike66" has been saying around this site, you can not change the regulator on a certified gas grill to an adjustable type to increase your input rate. This suggestion is not only illegal it is dangerous. By law any replacement part, particularly one that controls the flow of gas, MUST BE APPROVED FOR USE WITH THAT MODEL. If you alter parts or substitute them and play with the gas supply pressure, you are really on your own if the unit goes into melt down or blows up in your face.
Takeahike66, I wish you would stop leaving this suggestion all over this site, no manufacturer I have ever worked with would appreciate it and when there is a problem they will not accept any liability. Adjusting supply and manifold pressures should ONLY BE DONE BY LICENSED service techs.
