Selecting A Location; Installing The Boiler - Truma BG 10 Installation Instructions Manual

Selecting a location

The device must always be installed in such a way that it is
easy to access at all times for service work, and also easy to
remove and install.
Position the boiler in such a way that the cowl can be fitted to
an outer surface that is as straight and smooth as possible.
The wind must be able to flow around this outer surface at all
sides, and no decorative strips or panels should be present
there if possible, otherwise place the boiler on a suitable base.
The wall cowl must be attached such that there is no fuel tank
filler neck or fuel tank breather opening within 500 mm (A).
There must also be no living area ventilation openings within
300 mm (A). If the cowl has been placed vertically beneath an
opening window, the boiler must be equipped with an auto-
matic shut-off device in order to prevent operation with the
window open.

The boiler must not be installed close to or directly behind a
room heater.
In order to ensure that there is sufficient ventilation to cool
the electronics, the gap between the electronics cover (34)
and the walls of furniture items in which the boiler is installed
must be at least 20 mm.

Installing the boiler

Position the template for the cowl opening on the inner sur-
face of the wall.
A = Bottom edge of boiler
B = Lateral edge of boiler
Drill 4 holes (C) with a diameter of 10 mm through the wall.
Drill hole (E) with a diameter of 15 mm for the condensation
pipe (this can also be done from the outside = F).
Position the template on the outer surface of the wall. Mark-
ings (C) must be positioned over the holes drilled for the open-
ing. Use a saw to cut out the cowl opening (D) (92 x 168 mm).
If the gap between the outer wall and the boiler is more
than 35 mm, cowl extension VBO 2 will be required with an
extra length of 50 mm. Cut along the dotted line with a saw
(100 x 176 mm).
*
Cut out or support trim strips or the like on the vehicle so that
the cowl is level.
If the walls are sloping, support the boiler. The angle of tilt
must not exceed 10 degrees.

Line any cavities in the vicinity of
the cowl opening with wood so
that the screws can be tightened
firmly. The final cut-out should
be 168 mm high by 92 mm wide.

Figure 2
Push boiler with cowl part (1) through the cowl opening (2),
allowing it to protrude approx. 5 mm out of the outer wall. Fit
the sealing frame (3) (as a result of the anti-twist protection
the frame can only be fitted in the correct position). Pre-drill
holes for the 6 fastening screws (4).
Figure 3
Remove sealing frame (3) and coat on the vehicle side with a
plastic body sealant – not silicone.
The sealing frame must be well sealed to the front
faces and cross-braces of the cowl part (1) and to the
outer wall.
Attach the sealing frame (3) to the cowl part with
4 thread-forming screws (4).
Figure 4
Screw on the sealing frame (3) together with the
cowl part (1) so that the anti-twist protection
protrudes.

Seal the air gap between the hole (6) and the condensation
pipe (7) with plastic body sealant – not silicone.
Fit cowl grille (8). Press complete cowl onto vehicle wall and
mount using 6 screws (5).
Screw boiler securely to a suitable surface (plywood board,
laminated wooden battens or metal floor) on the vehicle floor
using at least two brackets (9) with the B 5.5 x 25 screws
supplied.
