I've just replaced a slot-in gas cooker (flexible hose) and with the front
lined-up with the cupboards on either side there's a 22mm gap at the back
between the top and the tiled masonry wall. The cooker's a Cannon Lichfield.
I assume there's a standard non-flammable widget available to fill the gap,
can someone enlighten me?
(If not I guess I'll need to get a piece of s/s box or L section).
