Gas Oven Problems

[yeoyeo]

Please help, I replaced an old gas cooker because it would light ok but then not go to the higher flame to heat up properly. Now the new oven is doing exactly the same. The gas ignites ok but then it takes over an hour for the larger flame to kick in.

Any ideas?

Get a CORGI registered engineer. What you are doing may be dangerous and also possibly illegal.

It sounds like you have low gas pressure.
