Wear and tear of the refractory, firebox aprons and related gaskets
The refractory material (insert stone and tunnel stone), the firebox aprons and the associated gaskets
are wear items and should be expected to be replaced periodically. How long these parts will last de-
pends on how much the boiler is used, how much wood is burned, the type and quality of the wood
burned, and how well the boiler is maintained.
Wear is perfectly normal and these pieces/items
must be replaced only when they are not fulfilling their functions.
Minor cracks and crumbling will not normally require replacing the refractory insert or tunnel stone as
long as they are still functioning properly. This kind of wear is perfectly normal, is to be expected and
is no reason for concern.
The removable firebox aprons are also subject to high temperatures and can become damaged or de-
formed over time. To minimize this damage and extend the life of the aprons, avoid long exposure to
deep ember beds. Ideally the boiler should not be re-fuelled until only a small ember bed remains in
the boiler or the fire has burned out.
