Extra-low-voltage lamps are to be
used
when
carrying
out
maintenance work in the storage
room. Electrical equipment in the
storage room must be designed in
accordance with ÖN M7137!
In order to prevent any maintenance errors, if
maintenance is not carried out properly, it is
recommended for maintenance to be carried out
regularly by authorised personnel or by the HERZ
Customer Service department.
Spare parts must only be obtained directly from
the manufacturer or a distribution partner. The
customer will not be exposed to any health risks
as a result of the noise generated by the machine.
Details on the residual risks can be requested
from the residual risk analysis at HERZ if required.

FUELS
2.1
Wood chips
Wood chips for non-industrial use with low fines
content after EN 14961-1/4 according to the
following specification:
Property class A1, A2, B1
•
G30 resp. G50
4
according to ÖNORM M7133
Particle size P16B, P31,5 and P45A
Water content min. 15% up to max. 40%
Ash content: <1.0 (A1), <1.5 (A2), <3,0 (B1)
m-%
Calorific value in as-delivered condition > 3,1
kWh/kg
Bulk density BD in as-delivered condition >
150 kg/m³
The property classes A1 and A2 represent fresh
wood and chemically untreated wood residues. A1
contains fuels with low ash content, which
indicates little or no bark, and fuels with lower
water content, while class A2 has a slightly higher
ash content and/or water content. B1 extends
origin and source of class A and includes
additional materials, such as short rotation
plantation wood, wood from gardens and
plantations etc., as well as chemically untreated
4
Only if using an agitator with 3x400 Volts
industrial wood waste. Class B2 also includes
chemically treated industrial wood waste and used
wood.
2.2
Wood pellets
Wood pellets for non-industrial use after ENplus,
Swisspellet, DINplus or ÖNORM M 7135 resp.
pellets after EN14961-2 according to following
specifications:
Property class A1
The maximum permissible fines content in the
fuel store must not exceed 8% of the fuel
volume stored (determined using a perforated
screen with holes 5 mm in diameter)!
Fines content at the time of loading: <1,0 m-%
Calorific value in as-delivered condition > 4,6
kWh/kg
Bulk density BD in as-delivered condition >
600 kg/m³
Mechanical Strength DU, EN 15210-1 in as-
delivered condition, m-%: DU97,5
≥
97,5
Diameter 6mm
The nominal power and the emission values can
be guaranteed up to a maximum water content of
25 % and a minimum calorific value of 3,5 kWh/kg
of the permissible fuel. From a water content of
about 25% and a calorific value <3,5kWh/kg a
reduced output is expected.
Foreign bodies such as stones or metal
particles should be prevented from entering
the system! Sand and soil lead to more ash
and slagging.
According to the fuel there may be a formation of
slag, which may need to be removed by hand.
In the case of non-compliance, any warranty
or guarantee will be rendered null and void.
The burning of unsuitable fuels could lead to
uncontrolled combustion. Operational faults
and consequential damage are likely to occur.
Is a different fuel on the order named and explicit
on the order confirmation noted, the system can
also be operated with this fuel.
Note: The system is set to the agreed fuel at the
commissioning. This setting (fan speed settings,
fuel settings, flow/backflow fan, cycle time, and so
on) should not be changed by constant fuel
quality.
