Unpack each element of the staircase before starting to assemble them. Position them on an ample surface and
check the quantity (TAB. 1: A = Code, B = Quantity). For "B" choose the column containing the code shown on the
packing crate label).
Assembly
1. Carefully measure the floor to floor height (H) (fig. 2).
2. C alculate the rise:
a) subtract 20 cm (height of the first rise) from the floor to floor height measured (H);
b) divide this by the number of rises minus one.
Example: for a measured height of 276 cm from floor to floor and a staircase with 14 rises.
(276 – 20 / 14 – 1) = 19.69 cm (fig. 2).
3. C alculate the number of spacers D61 necessary to form the chosen rise (TAB 2) and then couple them to the
intermediate supports N28 to prepare them for assembly (fig. 1)
Example: for a measured height of 276 cm from floor to floor and a staircase with 14 rises, the average value is:
(276 – 20/ 14 – 1) = 19.69 cm (the value obtained must be a number between 18.5 and 23.5 cm).
Calculation of the number of spacers: (19.69 – 18.5) x (14 - 2) / 0.5 = 28.56 = 29.
One at a time distribute the spacers D61 in sequence on the prepared part of the supports until they have all
been used up (fig. 1)
4. Carefully measure the floor opening (C) (fig. 2).
5. C alculate the value of the going (P):
For the version with a tread width (including the railing) of L = 70 (fig. 2A):
a) subtract the following fixed dimensions from the floor opening dimension measured (C):
1) 29 cm = last tread;
2) 64 cm= corner tread;
3) from 2 to 6 cm = distance from the wall.
b) Divide this by the number of remaining treads.
Example: for a floor opening of 221 cm and a staircase as shown in fig. 2A;
(221 – 29 – 64 – 2) : 6 = 21 cm
For the version with a tread width (including the railing) of L = 80 (fig. 2B):
a) subtract the following fixed dimensions from the floor opening dimension measured (C):
1) 33 cm = last tread;
2) 74 cm = corner tread;
3) from 2 to 6 cm = distance from the wall.
b) Divide this by the number of remaining treads.
Example: For a floor opening of 247 cm and a staircase as shown in fig. 2B;
(247 – 33 – 74 – 2) : 6 = 23 cm
For the version with a tread width (including the railing) of L = 90 (fig. 2C):
a) subtract the following fixed dimensions from the floor opening dimension measured (C):
1) 33 cm = last tread;
2) 84 cm= corner tread;
3) from 2 to 6 cm = distance from the wall.
b) Divide this by the number of remaining treads.
Example: for a floor opening of 263 cm and a staircase as shown in fig. 2C;
(263 – 33 – 84 – 2) :6 = 24 cm
6. P repare the straight treads L33 securing the parts F48 on the sides after fitting the parts B02 to them. Orient
the tread L33 with the central opening facing up and position the part F48 on the side where the railing is to be
fitted as shown in fig. 6. Using a 3 Ø mm bit, drill in correspondence to the hole in part F48 and finally fasten to
the tread with the parts BB5 (fig. 1/1B). In the same way and on the same side secure the second part F48 at a
distance equal to the value "P" (fig. 6) of the going determined previously in step 5.
7. O n the straight tread L33 before the curve, position only the first of the two parts F48 described above. For the
corner tread L36 secure part F48 exactly in the centre of the internal space (fig. 7). For the first triangular tread
(L35 or L37) position it keeping the centre 46 mm from the front of the tread. For the first triangular tread (L35
or L37) the part F48 must be positioned 46 mm from the rear of the tread (fig. 7).
8. Prepare the balusters of the railing C03 fitting the parts C63 joined to the parts C65 and C66 (fig. 5).
9. T o fasten the end support N29 to the ceiling consider that it is positioned horizontally in the centre of the tread,
therefore, to find the right position, add the space that will be left between the staircase and the wall to the
½ tread measurement (2-6 cm without external railing and > 6 cm with external railing) (fig. 3). Calculate the
position in height starting from the landing floor and going down by the value of a rise (calculated as in step 2)
plus the tread thickness (4.4 cm) (fig. 4). Check that the support is horizontal, position it correctly and mark the
fastening points in the ceiling (fig. 3).
10. D rill the ceiling using an 18 Ø mm bit. Secure the last support N29 using the screws C48 and check that it is
exactly horizontal on the tubular part (fig. 3).
11. Fit the plate cover D34 using the parts C62 and B12 (fig. 3).
