Received my SV24 today, but not my natural gas hose or the #51 drill bit that's required, but I'm looking at what fittings I'll need. From the propane, there is a L.P. regulator followed by what looks like a 3/8" male hose to female flare 3/8" female. The 3/8" flare female connects to the gas valve (3/8" flare male). When you convert to N.G. do you run without a pressure regulator? I know when I converted my grill, I inserted a N.G. regulator prior to the drilled out orifices. I'm guessing I will need a couple 3/8" to 1/4" reducers to (possibly flare to NPT), but I should be able to figure all that out once I understand the N.G. regulator.
