A frame can also be mounted for a single boiler, although a 1 boiler configuration does not fall within the cascade scope of this manual.
Table 8.1 Frame elements per cascade set
Attention!
Each set of material for the required cascade configuration will contain the exact amount of material required for
the cascade configuration type ordered.
8.2
Procedure for mounting the frame
See also Figure 8.1.
To mount the frame, subsequently carry out the steps in the following procedure:
1. Check after unpacking that all parts
are actually present.
2. Mount the in-between beam(s) between the L-stands.
Ensure that the beam’s flange hole falls over the raised edge of the L-stand connection hole.
Mount the beam(s) loosely; do not yet tighten the bolts.
3. Mount the top beam(s) between the L-stands.
Ensure that the beam’s flange hole falls over the raised edge of the L-stand connection hole
Mount the beam(s) loosely; do not yet tighten the bolts.
4. Level the L-stands, both vertically and horizontally.
Use a level and the adjustment bolts on the bottom of the L-stands.
Attention
!
The frame must be levelled tension-free.
So do not tighten bolts or mount boilers before the frame has been levelled.
Attention!
After mounting the frame, the frame must be braced or mounted to the wall or ceiling to prevent the frame and
boilers from wobbling.
Check the local building regulations for the relevant requirements.
