1.3.3 Entering the pellet storage room, storage container

All energy sources are subject to safety regulations which must be observed when working with fuels, heating
systems and storage rooms. This also applies to the storage of pellets.
After the storage room is filled, odourless carbon monoxide (CO) may be produced and there may be insuffici-
ent oxygen. For this reason, do not enter the pellet storage room for 6 weeks after it has been filled. Only trained
persons may enter the storage room for the purpose of measuring gas levels.
Please also follow the instructions on the sticker:
– No access to unauthorised persons, keep children away from the pellet store!
– Ensure sufficient ventilation before entering. Keep the door open while inside.
– Only enter the storage room under the supervision of a second person standing outside.
– No smoking, flames or other sources of ignition are permitted.
– Risk of injury from moving parts.
– Pellet boilers must be switched off at least 15 minutes before filling.
– Fill in accordance with the instructions of the boiler and pellet suppliers.
– Protect pellets from damp.
If you feel unwell, leave the storage room immediately and seek medical advice.
Attention!
Do not attempt to enter an unaired storage room (particularly buried tanks).

1.3.4 Combustion air

Never seal openings that have been provided for letting air in and out!

1.4 Fuel

To ensure that your new heating system provides long-term reliable service, the following must be observed:
Quality of pellets must be in accordance with EN 14961-2 A1:
The quality of the pellets is an important factor in achieving optimum operation of the heating system. When bu-
ying pellets, make sure that they meet the quality standards of EN 14961-2 A1 (or ÖNORM M7135 / DINplus). For
maximum reliability, source pellets from manufacturers with EN-Plus certification (or DIN-Plus, ÖNORM M7135
or UZ38), as they are required to perform ongoing internal quality control.
Diameter: 6 mm; Length: 80% between 15 – 30 mm and 20 % up to 45 mm
Make your pellet supplier aware of these quality requirements before ordering and seek confirmation upon
delivery.
Consequences of quality fluctuations:
Pellets are 100% unprocessed wood, so minor fluctuations in fuel quality are normal and reflect the natural ori-
gins of the material. These quality fluctuations affect the level of dirt, the ash content and therefore the cleaning
intervals.
A reduction in cleaning intervals due to fluctuations in pellet quality cannot be remedied as part of a repair under
guarantee!
