the fuel classes 4 (wood chips), 5 (shavings), 5a (pellet) may be used
in the HDG Compact 25 - 80 heating system and also for fuel classes
6 and 7 for the HDG Compact 45/50/65/80.

CLASS
6
Painted, varnished or coated wood including remains thereof, pro-
vided no wood protection agents have been applied or are present
as the result of a treatment, and coatings do not contain organic hal-
ogen compounds or contain heavy metals.

CLASS
7
Plywood, chipboard, fibreboard or otherwise glued wood including
remains thereof, provided no wood protection agents have been ap-
plied 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 wearing parts such as combustion chamber, fill level and
lambda sensors, which may reduce their service lives.
