3 Warranty, guarantee
Maintenance and repair
–Perform maintenance activities at the specified
intervals. No or incorrect maintenance leads to
inefficient operation, higher failure risk of the
boiler and increased potential for hazards.
Recommendation: Conclude maintenance con-
tract
–Have repairs carried out by qualified personnel
only. Improper repairs can lead to risks for the
user and impaired operation.
–Store hot ashes only in metal containers. Never
put hot or warm ash in the dustbin. High risk of
fire.
–For repairs use only original spare parts or parts
approved by the manufacturer (e.g. standard
parts).
Damage to the system
–If the electrical insulation on cables, plugs,
switches becomes damaged, switch off the power
supply and have the insulation repaired.
–In the event of visible damage (e.g. thermal
deformation, mechanical damage), operation of
the system must not be continued. The system
may only be operated if it is in perfect technical
condition.
3 Warranty, guarantee
–Warrant claims apply within the scope of a boiler
maintenance agreement.
–Warranty claims can be made by the customer
and the dealer has a legal responsibility to honour
them.
3.1 Technical requirements for warranty
and guarantee claims
The following technical requirements must be
observed as a precondition for a warranty and guar-
antee claim.
Further information on the individual points can be
found in the boiler's installation manual.
Regular maintenance and cleaning
–The boiler and the heating system components
must be maintained and checked regularly.
–This is the prerequisite for the following:
–Long-term reliability of the boiler function
–Energy-saving and environmentally friendly oper-
ation of the boiler
–Long service life of the boiler.
–Option/recommendation: Conclude maintenance
contract
–Documentation is crucial: When maintenance is
performed by qualified personnel, the activities
carried out/measures taken are documented in
the maintenance log. It is advisable to keep a sys-
tem book, especially when foregoing main-
tenance by qualified personnel (for
documenting/as proof of one's own activities).
Fuel
–The fuel used must meet the specifications.
–Non-approved fuel may lead to inefficient
combustion and cause damage to the boiler.
Specifications for the heating system's fill-
up/make-up water
–Check pH value: this must be in the range of
8.2 to 9.5
–Avoiding scale build-up (=limescale on heat
exchanger surfaces):
–Take the water hardness into account
–Soften the fill-up water, or better: desalinate it.
–Avoiding water-side corrosion (triggered by the
oxygen in the water):
–Correct system planning, correct dimensioning,
take material combinations into account.
–Repair leaks immediately.
–Expansion tank (prevents air suction when the
system cools down): Correctly set the pressure,
check it regularly.
–Existing underfloor heating: Take care with old, dif-
fusion-open plastic pipes (separate the system).
Sufficient ventilation
One of the most important basic requirements for
trouble-free operation is the removal of air and gases
in the heating system. Exposed expansion tanks or
underfloor heating systems that are not diffusion res-
istant can result in above-average boiler corrosion
due to too much air entering the system and because
of poor ventilation.
SOLARFOCUS recommends the installation of a
deaerator, such as a SpiroVent, in the hottest area in
the system.

3 Warranty, guarantee
Return temperature in the boiler
–A temperature below the dew point (leads to
corrosion in the boiler) must be prevented by a
sufficiently high return temperature in the boiler.
–In the case of the ecotop zero/light, this is ensured
by the return flow boosting which is integrated as
standard.
Supply air to the boiler
–The boiler can be supplied with air dependently or
independently of the room air.
–For operation independent of the ambient air
(room-sealed), a boiler-controlled room air flap
can be integrated in the line as an option.
–The supply air in the boiler must not contain any
aggressive substances. These substances can
cause corrosion in the boiler and chimney.
–Aggressive substances are, for example, chlorine
or fluorine compounds (used in cleaning agents,
solvents, adhesives, etc.).
3.2 Conditions for claims
For warranty and guarantee claims observe the fol-
lowing points:
–The warranty begins at the time at the time of han-
dover (delivery note, commissioning log).
–The warranty period is calculated from the date of
initial commissioning (according to the control's
operating hour counter).
–The warranty periods are based on the relevant
regulations.
–We must be notified promptly and accurately of
any damage incurred, so that the cause can be
clarified.
–If the system has defects despite correct install-
ation (in compliance with the technical doc-
umentation), we grant a warranty provided that
the system has been examined by the plant cus-
tomer service (commissioning log).
–The guarantee applies to technical, construction-
related faults and faults in the manufacture of the
system that prevent correct and problem-free
usage.
–We are not liable for parts that were not produced
by SOLARFOCUS. However, we are prepared to
transfer our existing claims against the producer
(relating to this defect) to the buyer.
–In fulfilling the warranty/guarantee services, we
shall cover only the assembly time and the mater-
ials used, but not any travel or accommodation
costs necessary for the fitters/engineers or any
return transport costs.
–SOLARFOCUS GmbH assumes no liability for
any consequential costs of damages.
–The repair and/or warranty replacement shall be
carried out on site or in the SOLARFOCUS fact-
ory at our discretion.
–The company SOLARFOCUSwill determine
whether such work requires a repair or whether
the parts are to be replaced free of charge.
3.3 Claims rendered void
The warranty and guarantee claims are rendered
void if one of the following points applies:
–Non-compliance with the technical requirements
> 4
–Damage during transport
–Wilful damage
–Damage due to force majeure (water, fire, etc.)
–Non-observance of information in the planning,
installation and operation manual
–Insufficient energy or water, fault in the hydraulics
–Incorrect operation, failure to perform main-
tenance and cleaning as prescribed
–Commissioning and maintenance carried out by
non-certified companies
–Undocumented commissioning (no com-
missioning log) and/or maintenance (main-
tenance log)
–It is almost impossible to produce flawless
painted parts; for this reason, slight defects that
do not adversely affect proper use shall not be
deemed as grounds for complaint.
–No claims can be accepted under the warranty if
unauthorised intervention (or action that has not
been explicitly approved by us the manufacturer)
has been carried out. In addition, the goods must
be paid for within the specified payment time-
frame.

4.1 Proper use
–The boiler ecotop zero/light is intended for heating
up water in closed heating systems.
–Only use fuel as specified in the next chapter
Fuel.
4.2 Fuel
Pellets
Use wood pellets only in accordance with these spe-
cifications:
–Pellets according to the ISO 17225-2 standard,
class A1.
–Pellets that meet the additional ENplus certific-
ation.
–Pellets that meet the additional DINplus certific-
ation.
4.3 Requirements of storage area/room
The requirements of a pellet storage area are
described in detail in ISO 20023.
The main requirements of a pellet storage area are as
follows: protect the fuel against moisture, ensure that
the storage area/room is well ventilated, provide ports
or filling points to allow pellets to be blown in from the
outside via a tanker.
As is the case with many biogenous substances, pel-
lets also emit small quantities of toxic and odourless
carbon monoxide (CO).
Particularly in the first two to three weeks after filling,
the large amount of pellets in the small air volume of
the store can lead to a critical concentration of CO.
This emission is usually associated with a build-up of
unpleasant odour. Pellets that were processed with
pine wood are particularly affected by this.
Filling pipe cover with ventilation function
To prevent CO from developing in the pellet storage
area, the filling pipe cover with ventilation function
has been developed. Even a small exchange of air
caused by temperature deviations between the
interior and the open air causes the CO to dissipate.
The filling lines should therefore by fed to the outside
and have as few bends or direction changes as pos-
sible. They must be electrically conductive and
earthed. The filling pipes must be located a maximum
of 2 metres above the footprint and must be equipped
with covers that are capable of ventilation.
4.4 Product description
–The ecotop zero/ecotop light is a boiler for the
combustion of wood pellets.
–The boiler has an automatic fuel ignition system,
automatic fuel supply and automatic heat
exchanger cleaning.
–The ash produced is collected in an ash con-
tainer, which must be emptied at regular intervals.
–Integrated in ecotop zero is an electrostatic dust
collector.
–This electrostatic dust collector can be retrofitted
on ecotop light if desired.
4.5 Spare parts
For repairs use only original spare parts or parts
approved by the manufacturer (e.g. standard parts).
The manufacturer cannot accept any liability for dam-
age caused by spare parts not authorised by the man-
ufacturer.

prevents overheating of the boiler and is integ-
rated in the boiler safety group.
–Functioning: The overtemperature reset stops the
heating process at a boiler temperature ~95°C
(exclusively electrical function; fuel and air supply
are interrupted).
–After tripping, the overtemperature reset must be
manually released again by unscrewing the black
sealing cap 1and pressing the button as soon as
the boiler temperature falls below 60°C.
–If the overtemperature reset trips, this is indicated
on the boiler control display.
Operation manual ecotop-zero, ecotop-light 7

4 Product information
Safety valve (to protect against excess pres-
sure in the system)
–The safety valve 1is a safety device for protecting
against overpressure in the water circuit of the
heating system.
–Functioning: The valve opens when the system
pressure exceeds 3 bar. Water/steam is dis-
charged into an open drain via a blow-off line,
which avoids subsequent damage to the com-
ponents of the heating system. The safety valve is
closed during normal operation.
–For normative specification see EN 12828.
iThe safety valve (or a boiler safety group) is
not included in the scope of delivery. This
must be provided on site.
Emergency OFF switch
–The emergency OFF switch is a manually oper-
ated safety device. The burner and the fuel supply
to the boiler are stopped. Circulation pumps
remain in operation to dissipate heat and cool the
boiler.
–The switch must be installed outside the boiler
room in a safe place that is easy to access.
Rotary valve
The rotary valve fulfils all normative requirements for
the approved fuels regarding fire protection, burn-
back safety, backflow of gases:
–Complies with requirements regarding burn-back
protection devices (BPD) according to TRVB 118
H.
–The single axis rotary valve prevents backflow of
flammable products of combustion into the fuel
supply (according to EN 303-5).
–Fire is held off from spreading into the fuel supply
(according to EN 303-5).
4.10 Efficient and low-emission oper-
ation
Please note the following recommendations from the
EU Energy Efficiency Directive:
Use of a buffer tank
Since maximum combustion is possibleonly in stand-
ard operation of the boiler, and greater losses and
higher emissions occur during the warm-up and burn-
out phases, use of a buffer tank is recommended.
This tank stores the water heated by the boiler, allow-
ing the connected devices (heating circuit, DHW tank,
fresh water module, etc.) to access it as required.
This ensures sufficiently long, uninterrupted com-
bustion periods for the boiler.
Use of high-efficiency heating pumps
When using external heating pumps (e.g. existing
heating circuit pumps, etc.), high-efficiency pumps
with energy efficiency class A should preferably be
used.
This delivers savings potential of up to 80 % in drive
energy (compared to conventional heating pumps)
with identical feed results.

4.12 Innovative technologies
Electrostatic dust collector[1]
To filter the last remaining dust particles from the flue
gas stream as well, SOLARFOCUS has developed
an integrated electrostatic dust collector. A special
discharge electrode with a high voltage of up to 30kV
ionises the fine dust particles, which then form a layer
of dust on the collection electrode. The discharge and
collection electrodes are cleaned fully automatically
together with the heat exchanger cleaning. External
cleaning facilities that frequently incur additional
costs are no longer required.

5.4.1 Required boiler values
Burner release time 1
The burner can start within the release times; outside
of these times, starting does not take place and/or the
burner is stopped. A time release from 00:00 to 23:59
means that no restriction is pending and the burner
may start at any time.
!ATTENTION - In order to protect against frost,
only automatic start-up of the heating circuit
pump is active outside the release time.
iDHW heating in summer
If the boiler is used for heating hot water, the
required chimney draught of 5Pa may not be
present in the summer months (or outside the
heating period). This may result in smoke
escaping in the boiler room.
Reason: High temperature on the chimney
stack (greater than 30°C); as a result, the
cooler air does not rise (~ 20°C air tem-
perature when the burner starts)in the chim-
ney.
Remedy: Set the burner time release from
00:00 to 07:00 or from 21:00 to 23:59.

Burner release outside temperature 2
The burner may not start if the outside temperature
exceeds this value.
External boiler release 3
On switches the function to standby. I.e. a connected
external boiler may only start when it receives the
release from the SOLARFOCUS boiler (e.g. on the
basis of a lack of fuel, operating fault).
5.4.2 Vacuum output
Release 1
Within the release times, the pellet suction turbine
can start. A release time from 00:00 to 23:59 means
that no restriction is pending and suction can start at
any time.
Intermediate pellet store filling 2
Pressing the button starts the suction turbine and the
tank is filled once (i.e. current level and release times
are not considered). Prerequisite: the boiler must
have the status Switched off or Standby.
Automatic diverter for suction heads unit
(optional)3
This button is only visible if the product has been pur-
chased.
Possible settings: 8
–Automatic: (Recommended setting) After three
successful suction procedures at a head, the sys-
tem switches to the next head. An even reduction
of the fill level in the pellet storage area is
achieved.
–Selectively: The heads are successively emptied
through extraction.
–Only head …: Suction is performed only at the set
head. Manual further switching in the boiler con-
trol is required.
Pressing the "Storage area/room
filled" 9button marks all suction heads
as full again.
Pressing the status button changes
the head status (colour red: head is empty; colour
green: head is full).
The arrow 10 above
the heads shows
which one is cur-
rently in use. Pos-
ition C 11 of the arrow means that the pellet hose will
be emptied through extraction. The occurs auto-
matically and takes a few seconds.
Manual filling 4
Pressing the button deactivates the automatic suction
system, i.e. the suction turbine may not start. (e.g. for
manual filling of the intermediate pellet store through
the inspection flap).
5.4.3 Heat exchanger cleaning
Release from-to:
Within the release times, heat exchanger cleaning
can start automatically. A time release from 00:00 to
23:59 means that no restriction is pending and the
functions can start at any time.

5.4.6 Operating hours counter
The operating hours of the individual outputs are lis-
ted in this menu. These are only counted when the
corresponding output is switched on.
The display of the pellet consumption is accessed by
clicking on the button 1. Pressing the Reset button
sets the pellet consumption back to 0 and in the bot-
tom area 4the consumption is displayed over the
elapsed time.
The heat distribution is reached via 2. Displayed here
are the operating hours during which heat was
requested by the various connected devices.
The integrated heat quantity measurement is
reached via 5. The pellet consumption is displayed
with maximum 15% deviation and is used together
with the efficiency factor for calculating the heat
quantity. The efficiency factor depends on the dif-
ference between the ambient temperature and flue
gas temperature, residual oxygen content and energy
content of the pellet 6.
There is no need for an additional heat quantity
counter.
The corresponding manufacturer declaration is
present and can be accessed here:
