2.23 Firebox lining

In the commissioning phase, it is possible that the lining is covered in a dark
layer. Once the operating temperature has been achieved, this layer on the
firebox lining will, however, have been burnt away. Cracks are not a reason
for making a complaint because the lining is subject to very high levels of
stress. An expansion or contraction crack is not serious and does not
represent any functional defect. However, firebox lining parts that have
moved position should be replaced.
If spare parts are required, these can be ordered from your fireplace fitter.
