Work on electrical parts of the boiler may only be carried out by an electrician and
in compliance with the electro-technical rules and standards.
Work on hydraulic systems may only be carried out by personnel with specialised
knowledge and experience in heating engineering and pipework construction.

• Licensing requirements for safe operation and accident prevention regulations
must be observed!
• Do execute verifications prior first start up.
See „Checks prior commissioning“ on page 12.
• Do execute verifications prior commissioning.
See „Inspections prior starting up the boiler“ on page 13.

II Safety regulations
2 Remaining risks
The following residual risks must be given special consideration when the boiler
is operated properly and in accordance with its intended purpose:
D A N G E R
Burns from hot surfaces or boiler components
• Switch off the boiler and let it cool down before carrying out any maintenance or ser-
vicing work
• Do not grasp into the boiler during operation.
• Wear heat resistant gloves.
The ash in the ash box does save heat.
• Put ash in closed, not-flammable vessels only.
Do not empty hot ash into dustbin
Scalds from sprinkling, hot water
• Check hoses, lines and connections periodically for leakages, wear and tear or any
other damage!
• Rectify damages immediately.
• Before performing any maintenance work on the water circulation system, depres-
surise the boiler.
• Check, if all valves are in correct position.
D A N G E R
Dust explosion due to electro-static charging in the fuel storage room
• Pay attention to proper grounding of the pellets transportation tubes
• No motors in the fuel storage room (acc. to country-specific regulations)
Except agricultural buildings
• No other source of ignition (e.g. light) in the storage room
• No electrical equipment (e.g. light switch) in the storage room
• No welding works in dusty environment
D A N G E R
Burns from explosive combustion of residual gases (CO) in the combus-
tion chamber
• Open the maintenance door carefully.
Slightly in the beginning.
Keep your body and face away from the maintenance door.
• Do not open the maintenance doorduring or straight after a power blackout.
The risk of deflagration increases significantly after uncontrolled conditions.
(e.g. power loss)
• Do not open the maintenance door during heating operation.

Safety regulations
D A N G E R
Risk of injury due to moving parts
• Omit access to augers or motors at operating boiler.
• Do not perform any work on the boiler when any person is in the danger zone
Secure / lock fuel storage room
• Only clean the augers and remove blockages using suitable tools and when the
main power switch is turned off.
• Wear safety shoes
• Observe fuel storage room sticker!
D A N G E R
Electric shock from contact with live terminals
• Observe information signs.
• Before starting work, check that no voltage is present using a voltmeter
D A N G E R
Poisoning and danger of suffocation due to flue gases in the boiler room / building
• Check boiler doors and seals for leaks.
• Burning treated wood (paint, varnish, impregnation) results in toxic ash.
Avoid skin and eye contact
W A R N I N G
Risk of injury due to unexpected operating statuses
• During manual mode no monitoring of limit switches or motors is performed.
Only run the augers backwards briefly (two seconds maximum).
• Manual mode is only allowed to be executed by trained staff.

II Safety regulations
3 Measures in case of danger
3.1 Fire in the boiler room
Switch-off main switch prior any fire-fighting operations
Disconnect main power supply
Switch-off the boiler and unplug the unit from the mains
3.2 After power loss
During the power failure, do not open the boiler's doors or reach into it.
Danger of deflagration
Danger of crushing through augers
After the electrical supply is switched on again, the control starts in Heat up mode
and monitors the flue gas temperature.
As the flue gas temperature increases, the boiler will heat up and control the
transfer of heat according to the preset parameters.
3.3 Leak in heating water system (no water)
If the water pressure is too low, not enough heat is being transferred from the
boiler to the heat circuits, HWT and accumulator.
Danger of boiler overheating
Turn off the boiler.
Fix leakiness
fill / refill water system
Check water pressure
3.4 Leak in the boiler (smoke escaping)
Turn off the boiler.
Check the seals of the doors and cleaning covers, and have them replaced.
3.5 Auger blockage(s)
Do not touch the augers.
Danger of crushing at sudden release of blockages
Briefly run the blocked augur backwards in manual mode (two seconds
max.).
Danger of squeezing of fuel in the auger
Only clean the augers and remove blockages using suitable tools and when
the main power switch is turned off and locked
