2 Installation
Set the middle section with the upper and lower hubs
(Fig. 13, Item 1 & 3) onto the nipples in the rear
sections. Note: the assembly arrow (Fig. 13, Item 2)
must point to the rear.
NOTE!
For easier assembly, locate the boiler
section to be fitted onto the nipple of the
upper hub first. Then align the boiler
section on the lower hub.
Drive the first centre section onto the end section
using a wooden or a rubber mallet (Fig. 13, Item 4).
Now compress the boiler block section with the
compression tool (Fig. 14).
ATTENTION!
Use only boiler compression tools size
2.2 or 2.3 (Fig. 1 or Fig. 2 and Fig. 14,
Item 1 & 2).
Push the compression units (Fig. 14, Item 3 & 4)
onto the pull rods (Fig. 1 or Fig. 2, Item 4).
Insert one pull rod through the upper and one through
the lower boiler hub.
Push additional pull flanges onto both pull rods
(Fig. 15, Item 3) at the back of the boiler (Fig. 15,
Item 1) and secure each with a wedge (Fig. 15,
Item 2) or cylindrical pin (for compression tool 2.2).
Hold the pulling rod at the centre of the boiler hubs
and, with the clamping nut, lightly draw together the
compression tools.
ATTENTION!
Never pull together more than one
nipple connection (two sections) per
compression step, otherwise the boiler
block could be pulled together
unevenly. This would lead to leaks at
the nipple joints.
