Hello all. I have a gas fire.

http://www.gasapplianceguide.co.uk/R...Black_03_1.jpg

anyway the middle 2 bars burn blue with the top quarter yellowish. The
outer
two bars are blue / orange normal

I have cleaned the jets that feed the venturi (?) and the venturi (?)
itself

the venturi is the block with the holes in that the gas burns from. (i
think)

It's quite difficult to clean this well, it becomes blocked with dust of all
kinds including particles of rust. I spend ages pricking each hole with a
fine sewing needle, prodding it several times. It does help. The ideal
solution would be to blow out the dirt in the same direction as the gas flow
but we can't do that easily with ours.
