Gas oven- flame size

In our new house, we have a Tricity Moffat 3000 gas oven. I've never
used a gas oven which is at waist level before, so I may not have
noticed typical flame sizes, but the flame on this one seems _very_
high.

Once it ignites, there is the usual low flame till it gets up to
temperature, but then it goes up to about 8 inches high, with no
significant visible change with different temperature settings- this
can't be right, can it?

Any suggestions- typical failure modes, adjustments on this model that
may have caused this, etc would be very welcome... also sources of
asbestos underwear ;-)

Er, isn't that what you'd expect & want from a thermostatically
controlled oven? Does the flame size decrease when the desired
temperature is reached?

OK, I'm obviously well behind with the times in gas oven technology...
I had always assumed gas ovens simply adjusted the gas flow to set the
temperature approximately, didn't realise some had thermostatic
controls... as it was _so_ much higher than I had expected, I didn't
feel it appropriate to hang around till it heated up.

[The previous owner had switched the power supply off at the back of
the oven when we moved in, which takes quite a bit of effort to get
at, and I was concerned this behaviour was due to a fault, which was
the reason for leaving it switched off.]

Thanks,
Nigel (retreating sheepishly...)

No, he says it's a small flame, then once it DOES reach the desired
temperature it goes up to 8 inches...

8 inches seems very extreme - I'd really think about getting the oven
checked over JUST incase there is something seriourly wrong...

No, I think the *initial* small flame part is just a soft-start to
ensure that you don't get an explosion when the gas first ignites.

If in doubt get it checked! Don't take my guessing as
gospel... Actually, it's probably a good idea to get
gas appliances checked over on general principle when
you inherit them by moving house...

Modern gas cookers don't have governors on so it could be the filter
governor on your gas meter is set too high or knackered.
Test the pressure at the oven this will tell you the working
pressure.If the working pressure is correct then it may only need the
burner cleaned as they burn floppy when the air ports are clogged with fluff.
