Slip in Cooker

We currently have a Zanussi ZCE7551X electric cooker which the manual describes on page 5 as an “Electric slip-in double oven”. It has a flat glass top.

As you can see in this image off the net
there is a plastic trim that could (and in our case does) fit up against the worktop.

We are wondering about getting a new cooker (although we may just get the old one mended). It seems that most cookers are either built in hobs, or require a space between them and the adjacent worktop.

Do such slip -in cookers in fact exist in the UK now? Googling only led me to obsolete appliances or to something similar that still exists in USA – called a “slide in range”.

Actually I’ve just found that the installation instructions say that an air gap should be maintained, even at hob level – yet this immediately follows a paragraph giving a different impression by stating
“a *nominal* air gap of 2mm at either side of the appliance is required to enable the appliance to be moved into position”.

Also I note that different manufacturers’ user manuals online give different interpretations of what a “Type Y appliance” is for the purposes of electrical / fire safety (whether it can have things adjacent to the back and two sides or only back and one side) – and I can’t find any official source that tells you what “Type Y” is or from what standard it comes.

It appears Zanussi’s cookers still only require a 2mm distance all round.

Kind regards
