Never assume anything - still on cooker hoods

I am replacing a cooker hood which had a two part "chimney" which was adjustable and was fitted to touch the ceiling.

The (much cheaper) replacement also has a two part chimney with the top part adjustable.

However this fits inside the main chimney, and all the electrics and top bracket and fan hose to the vent are also inside the chimney.

The last instruction says to fit the top part to the chosen height.

I hadn't twigged, until now, that if the top part was to be able to touch the ceiling then it meant that the top part of the chimney had to be dropped inside the main chimney after everything else had been connected up and the whole thing screwed to the wall.

Or you have to work with the top chimney inside, which gives you about

My tentative conclusion is that it is designed to have a gap between the top of the chimney piece and the ceiling, which may look a bit naff.

I may have got something wrong in all this but I don't think so. The instructions are sketchy at best.

I will have a look at the old one again to see how that worked, but my expectation would be that the top part of the chimney should fit outside the bottom part so it could be fitted last and reach the ceiling.

Ho hum.

Time for a sit and think, I think.

The main problem is that because the last one fitted right up to the ceiling I assumed that they all did.
