content and ash content must be met. Without the use of secondary
measures (filter technology), only fuels of property class A1 are
suitable for this in each case.
Pay particular attention to the fuel quality, both when ordering and
at delivery.
Important!
If there is a significant change of fuel, the system must be reset
accordingly and checked for emissions by authorised specialists.
HDG recommends log wood with a length of L50 (50 cm), a
maximum diameter of D15 (max. 15 cm) and a water content of M20
(20%). For kindling, we recommend log wood with a diameter of D5
(2–5 cm).
For fuel in accordance with section §3 (1) items 6 and 7 (German
ordinance 1.BImSchV), as well as for wood chips and shavings/
pressed wood briquettes, HDG recommends that these fuels only be
used if the HDG Euro 30/40/45/50 boiler is equipped with the special
accessory scale liner.

Additional quality requirements apply in Germany independently of
the fuel specification in accordance with DIN EN ISO 17225. In
accordance with Section 3 (1) of the 1st Federal Emission Control
Ordinance, the fuel classes 4 (log wood), 5 (shavings), 5a (wood
briquettes) and also fuel classes 6 and 7 may be used in the HDG Euro
30/40/45/50 heating system.
Painted, varnished or coated wood including remains thereof,
provided no wood protection agents have been applied or are
present as the result of a treatment, and coatings do not contain
organic halogen compounds or contain heavy metals.
Plywood, chipboard, fibreboard or otherwise glued wood including
remains thereof, provided no wood protection agents have been
applied or are present as the result of a treatment, and coatings do
not contain organic halogen compounds or heavy metals.
Fuel classes 6 or 7 may only be used in a wood processing plant at 30
kW or more nominal thermal power. In the case of painted, varnished
or coated wood, it should be noted that greater stress can be placed
on the wear parts such as the combustion chamber, burner nozzle or
lambda sensor, which may reduce their service lives.
