3kW wall mounting electric space heater (Kingsclere RG20)

This is a Dimplex QXD 3kW electric space heater.
It is new old stock I was given for use in my garage BUT please look at the minimum distance requirements shown in the photo.
This unit is way too hot for what I wanted it for.
So please be careful if you choose to use it.
It came with a broken element and a spare which I have fitted. I have NOT tested it in anyway. You must get it installed by a competent electrician who can earth it correctly and make sure that the cable supplying it is sufficiently large to take the high current load it will draw.
That said it is new and unused so should work.
It comes in its original packaging with full instructions and includes the wall bracket to allow it to be angled correctly, etc.
Collection is from Kingsclere.
