coal fire

[desrob]

the fire was previously a back boiler, it had pot tube like liners as a chimney,can these be used for solid fuel....

 

[ecowarm]

What is the internal diameter of the liner?

 

[desrob]

i did not measure it mate ,but at a guess...12inch

 

[ecowarm]

As long as its over 180mm its class 1 and ok for solid fuel

thats what i want to know is the pipe like pot liners that make the chimney from builders opening to terminal,would you class this as a class 1 chimney

 

[ecowarm]

Yep

 

[desrob]

i have a gas supply pipe in builders opening cemented through a bricked up wall,whats the regs distance on it been there if i want to change the builders opening from ilfe to solid fuel coal fire,surley it must be removed entirely

 

[ecowarm]

Well yes

 

[AWheating]

have you got a picture of the flue desrob? i cant quite imagine what its like.

for example if its a manufactured flue it must be rated above 400*c.

i would def remove the gas pipework completely. Check the thicknesses of the constructional hearth and builders opening walls etc... as building control checks can be failed on this type of thing.

I can't see it being a 12" liner. Afaik you don't get one but i may be wrong. Most brick chimneys are 9" x 9". Modern chimneys are lined with precast or salt glazed liners of 8 or 9" daimeter. If you are not sure get someone in to check at the customers expense.

your prob right regarding the size,i had a quick look and exaggerated the size,as you do,.nearer 9inch and defo glazed liners,i'm not doing the job just passing on info,whats the best way to go about tranforming builders opening,would you use chair brick etc.

You can buy pre made firebacks which is the easiest way of doing it or build it yourself with firebrick. If building it with baby brick you should use fondu cement.

Tamz right.
