Brunner KSO 33 - TOLERANCES OF THERMAL CONCRETE PARTS; Length Tolerances; Height Tolerances; Tolerances of Flatness

8 TOLERANCES OF THERMAL CONCRETE PARTS
The following tolerances are valid for all parts of our system fireplace/stove casings. Except where otherwise
indicated, all data refer to the nominal dimensions, as found in dimensional drawings.
Length Tolerances
For each part, the indicated tolerances apply.
Height Tolerances
For each part, the indicated tolerances apply.
Tolerances of Flatness
For parts with nominal dimensions up to 950 mm, a
tolerance of +/- 2.5 mm applies. Above this dimen-
sion, a tolerance of +/- 3 mm applies.
These tolerances apply also for the base support
and top cover parts. The leveling board (R) must be
placed in parallel to the basic body!
