Well utluckly...its different in different places. Where I live, we dont get alot of freezing days on average and I am kinda in the country so all I had to do was go down about 6 inches. The reason I had to go 160 feet was because I didnt want the line to run across my yard, because I thought I might get a pool one day. So with that, I ran my line along my house and then over to the greenhouse, If I drew it out, it would be an "L" shape. I had my trench dug and my whole cut in the greenhouse, when the plumber came out, I showed him what I wanted, talked with him about the size of the pipe because of the distance and showed him the greenhouse. All the plumber did was lay the pipe in the trench, connect the pieces together, hook it to the gas meter and put me a stop value in the greenhouse. My plumber charge me $1.90 a foot. That included pipe and labor. Now, if you have someone that can tell you the size pipe you need, you can go buy your own pipe and bargan for the labor. Just remember that most plumbers charge by the foot for gas work. If I had ran it across my yard, it would only have been 113 feet and around $200. NOW...if you live where you have alot of rules and things have to be so so, you might want to check with your plumber and see about the depth of your area. If you have to dig deep, you can rent a ditch witch and save alot of time. Hope this helps, Rob

I don't know about the CharBroil, but I converted my Members Mark to NG a year ago by drilling the orifaces for the main burners to 5/64's and the back burner to 1/16th -- this may at least get you started in the correct direction. When you convert to NG you do not need a regulator. One less thing to go out. ;->

We have no choice but to go with LP. We have electric ovens but I thought there was some difference in the amount of moisture created using LP vs NG which may make a difference in oven cooking. Maybe others can confirm this. The tank I have been told is not expensive to buy (a few hundred dollars). We are not that far along to make that decision just yet. If we had a choice though, I would certainly stay with NG as that would give me more choices in appliances. LP may also be more expensive per unit of heat given the transportation costs. I did the math for heating the house this way and it was astronomical from what I recall. As to needing high heat, our current plan is to get a dedicated wok induction hob. That solves the high-power requirement and opens other options like Wolf beside Bluestar. Below is the experience of someone with wok induction. Here is a link that might be useful: wok induction performance

I have not needed to change to propane with an old classic range, only the new style. However, it seems clear to me that you would only need to adjust each burner to your own desire. The nice feature about open burners is that you can control gas volume with an adjustable nut and you adjust air volume with a slide shutter that you just push more open or closed by hand and a screw driver. More gas, more air; less gas, less air; just barely no yellow flames; no problem.
