Stuart -- thank for suggestion but grillparts.com doesn't list the model
-- a "Superb by Broilmaster" Model SBH200-1 Natural Gas Grill.

Near as I can tell, Broilmaster sold those w/o regulators to
distributors who bunged in whatever regulator they had on hand, as the
regulator is not in the owner/assembly manual's part number listing and
shown only as a generic circular object labeled "regulator" in the
assembly illustration.

Phil, good point.

We had a serviceman out here a couple years ago to diagnose a stove
problem in the house and he measured the pressure and it was spot on at
7'' W.C. and the stove has not changed behavior since then so I suspect
that the natural gas pressure is still good.

The regulator on this BBQ is marked: "GLOBAL Model 7010 PSIG 1/2, Nat
4''-LPG 10'' "

Which suggests a further step-down in pressure from 7'' W.C. to 4'' W.C.

(How the regulator could be marked for two pressures begs a question:
how does it know what kind of gas it is being fed so it can select
between the two output pressures?)

I suppose I /could/ try bypassing it, but the resulting flames from the
burners might be more spectacular than normal, and unlikely to be the
proper fuel / air ratio for a clean burn.

Googling isn't helping find this part. Robertshaw makes a few kits that
are said to fit the 7010 series of regulators, one labeled for dual
fuels (but sez lpg 3.5'' and ng 11'') so it's not a solid fit although
it does look physically like this device.

Oh well, it's not Friday and this grill ain't a Vanagon and we can't
pretend that it somehow qualifies for listworthiness because it's not
even a propane grill. I'll have to keep looking. Many thanks, all.
