1.2 Warranty, guarantee and liability
Requirements
We can only accept liability for the function of our
products if they are correctly installed and operated.
This is only possible if the conditions below are
complied with.
Observe local building and fire safety regulations
Local building and fire safety regulations must be
observed.
Suitable fuels
• Wood chips according EN ISO 17225-4:2014,
quality classes A1/A2/B1/B2, size P16S-P31S,
maximum water content 35% (M35)
• Wood pellets according EN ISO 17225-2:2014,
quality class A1, ENplus-A1
• Shavings and swarf briquets according EN
ISO 17225-3:2014, quality classes A1/A2/B
• In Germany: fuel classes 4/5a according
1. BImSchV. Use fuel classes 5/6/7/8 only after
consultation with company ETA.
Operation with unsuitable fuels, in particular high-
slag pellets from grain waste, for example, or
corrosive fuels such as miscanthus fertilised with
potassium chloride, is prohibited.
Expanding the control system
Only components provided by us may be used for
expanding the control system, unless these are
generally available standard devices, such as thermo-
stats.
Regularly perform cleaning and maintenance
Cleaning and maintaining the product is essential. The
required steps and intervals are either contained in this
documentation or included as a separate document.
Repairs
Repairs are only permitted using spare parts provided
by us. The only exceptions are common standardised
parts such as electrical fuses or fastening materials, as
long as they possess the required features and do not
restrict the functionality of the system.
Proper installation
The installing contractor is liable for proper installation
according to the corresponding installation instructions
and the relevant rules and safety regulations. If you as
customer have installed the heating system partly or
entirely without relevant training and in particular
without up-to-date practical experience, without having
the installation checked by a trained and responsible
expert, we exclude defects in our delivery and conse-
quential damages resulting from this cause from our
warranty, guarantee and liability.
Repair of defects
For repairs of defects carried out by the customer or by
a third party, ETA shall only bear the costs or remain
obligated by warranty if this work was approved in
writing in advance by the customer service of ETA
Heiztechnik GmbH.
No tampering with boiler safety devices
Boiler safety devices such as those mentioned below
must not be tampered with: Temperature monitoring
and control devices, safety temperature limiters, safety
valves and thermal discharge valves.
No water or moisture in this area.
No leaks in the components, e.g. screw con-
nection or maintenance cover.

Installation

4 Installation
Assembly and installation only by qualified
specialist personnel
The assembly and installation may be performed
by specialist personnel with the corresponding
qualifications only.
Installing support stands
Mount the both support stands on the lower part of the
drop chute.
Fig. 4-1: Support stands
Assembling the light barrier
Screw the transmitter (as well as the receiver) of the
light barrier into the mounting plate. Only hand-tighten
the lock nut initially.
Fig. 4-2: Transmitter/receiver in the mounting plate
Only install the transmitter and receiver hand-tight on
the lower part of the drop chute.
Fig. 4-3: Light barrier in lower part of drop chute
There is no defined mounting side for the
transmitter and receiver of the light barrier.
Check the position of the transmitter and receiver. The
curvature of the lens must overhang on the inside so
that it is cleaned by the falling fuel.
Fig. 4-4: Correct position
If the lens protrudes further into the interior, dust
can accumulate and thus interfere with the
function of the light barrier. If the curvature of the lens
protrudes too far, twist the transmitter (or receiver) out
of the mounting plate accordingly and fix it in the
correct position with the lock nut. Then carefully tighten
all screws.

Installation
Mounting the trough on the lower part of the drop
chute
Affix a seal to the flange.
Fig. 4-5: Seal
Grease the drive stub of the conveyor screw with
Stauffer grease and connect it with the existing
conveyor screw.
The grease protects the connection from
moisture and thus prevents rust. Therefore the
connection can easily be detached later for necessary
repair, for example.
Fig. 4-6: Conveyor screw
Make sure that the thread is continuous.
Fig. 4-7: Continuous thread
Mount the closed trough on the lower part of the drop
chute.
Fig. 4-8: Closed trough
Attach a seal to the flange. Repeat these steps if
several troughs are installed.
Fig. 4-9: Seal
Mounting the drop shaft for the start of the inter-
mediate screw
The drop chute from the delivery scope of the in-
termediate conveyor screw is always mounted on
the lower part of the drop chute, i.e. always at the start
of the intermediate conveyor screw. See the following
graphic.
