Fire was a doddle to install and looks great. I only really intended to use it as a visual feature, for which it is excellent in its realistic fire. It can also output heat if required

Got my fire fitted Monday ! Absolutely love it but after having it fitted by the store fitter had to take it apart as didn’t think the fuel bed was right ! But redoing it was a nightmare ad the gap between the the fuel bed and the glass insert was very slim and very awkward to install the the glass stones and tiny embers which kept falling into thr gap where the glass goes . I think it would be a better design if the embers were set onto something so that it would just slot into the space as the fitter had not installed this model before . I think to get the embers correct it would be better if pre set as it should be as spent many hours trying to sort it and still not sure it’s right . But a luvly fire with amazing flame affect just wish the lower bed & logs was attached to a board or something to allow it to give the effect it should have as it very fiddly to achieve
