3 . 2 Assembling the sections
The sections are assembled using nipples. For a good
tightness of the assemblies, it is compulsory to use a special
product which ensures a perfect seal (this coating is always
provided with the boiler).
Proceed in the following way:
1) Open the "Extra accessories" box,
2) Clean the nipples with a solvent,
3) Put the rear section in vertical position and secure it
against tilting by propping it up,
4) Position the wooden block provided in the "extra
accessories" box, 40 mm thick, in front of the rear
section’s legs,
5) On the vertical section, clean the groove awaiting the
cord with a metal brush, then position the cord
without stretching it, with the junction point at the top
(see figure 6) on the axis of the nipples line.
Cut the cord carefully.
6) Clean carefully with solvent the receiving surfaces. If
need be, use extra fine emery paper in case of rust
stains or small barbs.

7) NEVER USE OLD NIPPLES.
Coat nipples and reams with the product provided,
using a clean brush.
8) Place the nipples in the vertical section’s orifices and
drive them in slightly using a piece of wood on which
to hit with a hammer or a mallet so as to maintain the
nipples in the reams. Do not drive them in too much, so
that the final tightening shall be obtained by bringing the
sections together.
Take care that the nipples be perfectly vertical, as a
deviation during tightening can break the section,
9) After having cleaned the middle section and applied the
coating, bring it on the block to place it facing the
vertical rear section and respecting the orientation of
the
assembly marking which must be always oriented
towards front (see figure 6).
Drive it onto the two nipples using a mallet or a piece of
hard wood, hitting alternately, at top and bottom, facing
the nipples to ensure temporary assembly of the two
sections,
10) Ensure that they are perfectly vertical, and tighten it as
explained in the following chapter.
