If it appears that the GAS appliance has been tampered with, it's an
indicator that the appliance could be unsafe, and also that it's possibly
been returned by a previous buyer when it was discovered that the output was
lower than expected.

Undercooked food will make people very sick.

OK, I've boiled a litre of water in a 2 litre pan on the large 100mm ring
and it took around 6 - 6.5 minutes, kind of in the same ballpark as Phils
results.

Thing is my probably 20 year old cooker had 4 small rings of the same
size, but they were quite powerful, so my french fries experiment was done
on one of the medium sized rings of the new cooker, and they are not
powerful enough to cook them. So I was comparing Apples and Oranges there.
The 100mm ring probably would do fine with a suitably larger pan, so
perhaps there's nothing wrong up top.

The oven definitely has a problem, and I have noticed the floor pan above
the burner is bent with a damaged philips screw holding it in, so someone
has been messing with it. I will investigate this later.

Phils 250oC in 15 minutes is what I would have expected from my old
cooker - this equates to Gas Mark 8. This one never got above Mark 5
despite 45 minutes on full blast.
I believe the thermostat is reasonably accurate because it tallies with my
common experience of putting a chicken in the oven at Mark 8 and Mark 5.
The results last night were definitely Mark 5.

The cooker did come with an extra set of jets and some kind of choke (?)
coupling for Propane gas - the packet is clearly marked as to what they
are, the fitters pointed them out too, so I don't think the wrong jets are
fitted.


I'll do the Gas meter calculation, probably over the weekend - will again
run the oven on full for an hour and see how much gas it has used, and see
if it has cooked my shoulder of lamb.
I know for a fact it won't do roast potatoes right now. Bummer.


Thanks to all,


Gareth.
