Maybe the handle on the valve is turning, but the insides are not. Also, follow the line back into the house to see if there might be another valve downstream that got shut off. Another possibility is that the female portion of the quick connect is probably steel, and being in the weather, has developed some rust inside and a check ball is hanging up.

I have the Weber Performer. It's an awesome grill. I used a Weber kettle for years with great success, but in a moment of weakness I retired it for a Weber Genesis gas grill. Gas grilling is convenient, but it's not the same. Last year I purchased the Weber Performer to get the convenience of gas starting, but the cooking flavor/performance of charcoal. First, the propane assist is just a charcoal starter. I stack the charcoal in a compact pile over the starter and ignite it. Of course the bottom vents are wide open and the lid is off at this point. After about 3 or 4 minutes, I can hear the charcoal snapping, popping, and smoking to indicate it's "lit." I turn off the propane and let the charcoal burn down until nearly all sides are covered with fine layer of ash. Then, I knock the pile down and spread it evenly across the bottom grate for cooking. Now, I put the top grate and the lid on and open the top vent wide open. I watch the temperature climb to >400 degrees, then open the lid and brush the top grate to clean it. Close the lid and use the upper and lower vents to control the airflow and thus the temperature. After some experience, I know just about how much to close them down to hit a temperature range I'm after. This assumes you're using good quality charcoal and not using too much of it. I prefer the hardwood "lump" charcoal. The old standard Kingston briquets don't seem as high quality as they once were. If, for instance, I'm cooking hamburgers, I'll have just enough charcoal to cover the bottom grate with the chunks spaced 1/2" to 1" apart. Hamburgers cook pretty quickly. Don't use the little half-round trays Weber includes to hold the charcoal for normal grilling. Those are for special circumstances when you want indirect heat. When I'm done cooking, I close all the upper and lower vent to extinguish the charcoal. I use the leftover charcoal from the previous grilling as the base of for the next cooking and add a little more from the bag to make the pile I want. If you aren't getting to the temperature you want, you may have crappy charcoal, inadequate airflow, or impatience.

Java, Has the grill ever worked when attached to this stub out? If not, you might want to check (or have the plumber check) the connection of the gas line from the stub out to the main manifold. It's likely in the attic. If it's not the main connection, the quick-connect you are using SHOULD cause the gas to flow when seated and the house-mounted fittings SHOULD close when the quick-connect is undone. The Someone over on the plumbing board probably can answer your questions best since it seems like a plumbing or fitting issue of some kind and not one related to the grill itself. Michelle

Blowers are pretty much a motor , a fan blade and a (realatively) simple speed control. It's either constantly variable or a 3 speed variable set up. If you can dope out the wire hookups from the schematic any combo is possible. Now you'll run into support and warranty issues but for instance a BEST roof blower at 1500 cfm retails at $925 and their 1100 cfm inline blower goes for arounf $700 bucks. Fantech makes some nice inline blowers and they do not make exhaust hoods. So.......... I would not go the single popup route. It only has an effective capture area of 15 ". That is only going to cove half your top at best even with the pivot feature. I still stand by my rec that you'd be better off with the T'Dor/ Best/Wolf, Viking, ect... pop up splash than even if you have to have a gas grill. These things are way stylish and can work fairl good if the are placed accurately which you don't seem able or willing to do. One would have to pivot directly over the grill surface to be more effective that the other type. It's still only mildly better. Are you dead set on a gas grill? Weren't those J Airs elect??? Why not get an elect. combi, a normal full width pop up downdraft with a reasonable priced and powerful blower and whatever gas eyes you like? This should provide the type of cooking you seek at a reasonable price and still perform pretty good? Didn't make it to the office so can't give you gaggi $$$.
