If your fire predates the fan, then you have an exhaust unit or something similiar, so clearly you can use the fire in a normal flue. But why did you go to the expense of the fan and conversion, and trunkating thre cimney? All sounds a bit weird to me.
Yes it was weird and will try to keep it short but:
I had two chimneys in two separate rooms on the same wall, they went straight up until they met in the Loft in an A shape, topped by the chimney.
I had one chimney totally removed all the way up, leaving the remaining servicing the fire. Few years later I heard slight sound of something falling down the chimney, this went on over 8 days, not constantly but every few hours. Called in a Construction Engineer to tell me if it was safe or not and was charged a professional sized fee to tell me "Yes it was".....BUT if it wasn't, here is a plan of a Heath Robinson type contraption to support it. So I was none the wiser and to add insult to injury, he put his foot through the loft leaving a 10cm hole for me to fill !
As it was still an unknown quantity and for safety's sake, I decided to have the "lean" part of the chimney removed from the Loft (I bet you wished you never asked now!)
I don't understand what you mean. Are these holes part of the fire or actuall in the chimnbey? Any chance of a photo?
The holes are part of the fire, as if the fire grate was supplied in its own containing "box" and then the box slid into the original hearth so the back, sides and top are not the original hearth, the holes are set high at the back of the box facing outwards (as opposed to the top of the box facing downwards).
Photo Fire1 shows the fire, the holes are way up underneath the Hood.
Photo Fire 2 shows the back & side of the "Box".
I tried to take a photo of the holes but as I've only recently turned the Fire on, almost burnt my brains so can try that later. The fire has been on for about an hour has turned itself off once already and will probably be getting noisier soon so I will have to turn it off.
That doesn't make any sense at all. If the fire is a standard ntural draught fire, and an exhausto type system has been fitted retrospectively, then, clearly, you CAN just change the fan! Unfortunately not all showroom staff are clued up. Did you buy the fire or conversion from this showroom? If so, ring again, and ask to speak to the proprietor.
I'm sure the Fan can be replaced but I think the Showroom may have "blacklisted" me because I had the nerve to complain about the standard of work after the Flue had been fitted.
They told me it would be quiet - It isn't.
They told me the Fan doesn't break down - It has.
The Fitter left the gaping holes in the plaster after replacing the surround.
Dragged the cast iron surround across the polished slate hearth leaving many deep scratches.
The roofers they provided at the same time placed the extra roof supports for the heavier tiles onto a piece of 4x2 placed across the main beams instead of the main beams themselves.
You probably can reinststate the flue. You could rebuild the chimney in it's original form, or you could line it. However, if you have an INSET TRAY fire, then you may well need 7", rather than the more common 5", so you need the manufacturers instructions for the fire. You cannot just start the liner from the chimney stub, as, under part J, you cannot reduce the cross sectional area of the flue part way along it's length
I'm keeping note of all this extra advice !
