3 Installation room
3.1 General information
Minimum size of the installation room
For installation, on 3 sides the boiler room must be at
least 200 mm bigger and one side at least 1000 mm
bigger than the external dimensions of the ETAbox.
The entire vertical height up to the ceiling can be
used as the height of the ETAbox can be set in
100 mm increments.
Minimum clearance between the boiler and
ETAbox
Depending on the country-specific regulations, a
minimum clearance must be kept between the ETAbox
and the boiler.
Country-specific building and fire protection
regulations must be observed. It is possible that
setting up the ETAbox in the same room as the boiler
is not permitted.
Minimum 200 mm gap to the wall
On the opposite side to the filling nozzles, a minimum
distance of 200 mm must be maintaned from the
adjacent wall. So that the pellets are cushioned by the
fabric sack during filling and do not shatter against the
wall.
Permanent ventilation and extraction is necessary
Permanent ventilation and exhausting of the boiler
room must be available, for example, through a
window.
ETAbox may not make contact with damp walls
The fabric sack of the ETAbox may not touch damp
walls.
Protecting the fabric sack from UV light
Prevent the fabric sack of the ETAbox being irradiated
by UV light, because then the fabric sack will become
brittle over longer periods of time. Attach dark film or
transparent UV protective film to the window, for
example.
Protecting the fabric sack against damage
Remove or cover pointy or sharp objects near the
fabric sack in order to protect the fabric sack.
Outdoor installation is possible
Outdoor installation is possible if the ETAbox is
protected from the effects of weather. A waterproof
roof as well as side covers are absolutely essential.
The pellet hoses must also be protected against UV
light and sunlight.
Sufficient load bearing capacity of the floor
The floor below the ETAbox must have sufficient load
bearing capacity, because high loads are exerted on
the individual support surfacesformaximum filling; see
2 "Technical data"for more details.
If the ETAbox is set up on a floating screed
(insulation under the screed), the screed in the
area of the support points must be removed and the
area must be filled with concrete.
Or 2 x 12 mm round steel (either threaded rod or
concrete iron) must be placed at each support point of
the feet and on each corner of the extraction unit. Drill
at least 30 mm through the screed into the concrete
floor, clean out the hole, drive the round steel into the
base of the hole with a heavy hammer and cut off the
protruding end.
Extending the filling nozzles
Optional extensions and 45° arches are available for
the filling nozzles. The filling nozzles are extended with
these and thus made accessible.
The extensions may only have a few changes of
direction and the maximum length may not
exceed 10 m.

5 A minimum clearance must be kept between the
ETAbox and the boiler (dependent on the country-
specific regulations)
Before assembly, the ETAbox's final position in
the room must be determined. The following
points are to be observed in the process:
• The extraction unit of the ETAbox is to be set up so
that the connectors for the pellet hoses are aligned
with the boiler and easily accessible.
• Orient the ETAbox so that the filling nozzles are
accessible for later filling, If possible, the ETAbox
should abut an external wall, so that the filling
nozzles are accessible from outside. The filling
nozzles can be extended if required.
• One of the two side inspection ports must be easily
accessible for monitoring the fill level in the fabric
sack of the ETAbox.
• On the opposite side to the filling nozzles, a
minimum gap of 200 mm must be maintained from
the adjacent wall, so that the pellets are cushioned
and do not shatter against the wall.
• A minimum clearance must be kept between the
ETAbox and the boiler depending on the country-
specific regulations.

Information about pellet hoses
4 Information about pellet hoses
Suitable pellet hose
DN50 pellet hoses with copper litz wire (for earthing)
are required for the suction and return air.
Maximum length - 20 m
The maximum length of the pellet hose is 20 m.
Minimum bending radius: 250 mm
The minimum bending radius for pellet hoses is
250 mm.
If the radius is below this value, thecross section of the
pellet hose is reduced and the friction on the inner
walls increases. As a result, the pellets are damaged,
blockages can occur and the service life of the pellet
hose is reduced.
Installation tips for pellet hoses
Fig. 4-1: Unroll pellet hoses instead of pulling them out
Fig. 4-2: Note bending radius
Fig. 4-3: Avoid twisting pellet hoses
Fig. 4-4: Use pipe guides or pipe supports
Single-piece suction hose
The suction hose for the pellets must always consist of
a single piece.
Suction hoses made from several parts have higher
friction on the inner walls, which can result in damage
to the pellets.
Only the pellet hose for the back air may be made
of multiple parts.
Straight paths
Lay out the pellet hoses as straight as possible.
Suction hoses laid out in loops have higher friction on
the inner walls, which can result in damage to the
pellets.
Earthing
The pellet hoses must be earthed as they acquire an
electrostatic charge during pellet transport. A copper
litz wire is moulded into the pellet hoses for earthing.

Information about pellet hoses
11
On the ends of the pellet hoses, free around 5 cm of
copper litz wire from the hose and bend it inwards into
the hose.
This establishes a contact between conveyor and the
boiler. At the boiler, the copper litz wires are clamped
to the earthing cable near the pellet hose attachment
nozzles.
No contact with uninsulated heating pipes
The pellet hoses are designed for a temperature range
of -15°C to +60°C, so they may not come into contact
with uninsulated heating pipes.
UV protection outdoors
When pellet hoses are installed outdoors, they must be
enclosed in a protective conduit to protect them from
ultraviolet radiation. If the pellet hoses are not
protected, they can become brittle, leading to a
reduced service life.
