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.
2 FUELS
The HERZ pelletstar
– boiler should be operated
with the fuels and their properties which are
described in this chapter.
2.1 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.
