Materials

Each model has it's own specifications. Despite this, there are a number of common issues that are presented below.

The bricks in the combustion area and in the secondary combustion chamber/flue will get very hot during operation. Common building bricks will disintegrate if used in these areas.

The mortar is composed of high alumina refractory cement and refractory granulates.

Mild steel is subject to corrosion, especially in those areas subject to high temperatures and combustion gases. Therefore, although some variation in the specified materials is possible, it is recommended that steel plate thickness is not reduced merely to simplify construction.

Rolled steel angle components may be made from the nearest available size to that specified. There is a lot of tolerance here provided that the chosen size is not significantly weaker than that specified.

U section (channel) is likely to prove the most difficult to obtain in the size specified. It can be made by welding together two lengths of rolled steel angle to form a U section of approximately the specified dimensions.

Door hinges and fasteners may be made in any manner available to the constructor and agreed by the user.
