A.-Lighting up for the first time
Once installed in its final position, check that all joints have been sealed to prevent
outside air from entering, which would affect the draw.
Before lining the fireplace with bricks or any other incombustible material, check that
it works correctly.
We recommend a slow fire for 3 to 4 hours when lighting-up for the first time. This
will help stabilise the different components and avoid any possible breakages.
It is advisable, when lighting the fireplace for the first time, to open windows to let
any fumes or odours that may be caused by the combustion of the protective paint
solvents or any other material to escape.
