I see you have a single-stage regulator which is not sufficient for this
job. You need 1) a two-stage regulator and 2) it must have an inlet
fitting which will shut off the gas in case of a large leak. In USA that
is called "excess-flow POL fitting" -- POL is the name of the round-nosed
fitting with left-hand thread that couples the regulator to the valve on
the external tank. The male (regulator) side contains the mechanism to
shut off excessive flow.
In USA these devices must have regulatory approval for RV use and will be
marked as such. The standard replacement for the square Marshall Brass 260
regulator which was original equipment is the (longer, <sigh>) Marshall
Brass 290 which still fits with some bending of the tubing going into the van.

American spec is 11 or sometimes 11.5 inches H2O; 11 inches = 280mm. I do
not think the tolerance is as large as you state. I think perhaps that
tolerance is for barbecue grill regulators, not RV regulators. The
instructions from Dometic seem to suggest a tolerance of maybe only +/-
10mm for best performance.

Don't know.

I believe this is the same.

I understand that when you say level you mean pressure. :) I am only
familiar with the Marshall Brass series of regulators, which have
adjustment for the second (low-pressure) stage, but not a gauge. A gauge
to measure this very small pressure will be quite expensive, probably more
than the regulator itself. Is it possible that your best answer will be to
have someone here obtain and send you a correct regulator? They cost under
$30 US including the POL fitting and weather covers.

ps -- are you anywhere near Gumma-Ken? I have a friend who lives at the
special hospital there.
