2.13 SETTLEMENTS
The refractory mortar used for the internal walling contains always a little moisture that is
eliminated after the first periods of use: so it is normal that the first times you light the cooker or
the thermal cookers a little condensation is being generated. All the refractory materials inside the
cooker experience a settlement process that may generate small holes on the bricks, such holes do
not preclude anyway the working of the cooker. Other settlements may involve other parts of the
cooker so during the heating and cooling phases you might hear light noises. These symptoms do
not absolutely preclude the use of the cooker and fading out till disappearance with the constant
use of the cooker.
