2.1 General safety instructions
Comply with the following instructions corres-
ponding to your boiler ( oil or gas ).
The system may only be placed in operation if
all the relevant standards and safety regulations
have been complied with. Fault-free operation
can only be guaranteed if the operating instructions are
followed.
The rectification of faults and damage resulting from in -
stallation in unsuitable rooms, e.g. hobby rooms, work-
shops, etc. as well as the use of contaminated operating
materials (gas, water, combustion air), unsuitable che-
mical additives to the heating water, improper handling,
faulty installation, unauthorised modifications and dama -
ge due to the use of force do not fall under our obligations
under warranty.
Behaviour in case of danger
Cut off the fuel (oil/gas) and electricity supplies.
Disconnecting the electrical power supply
The heat generator can only be de-energised by discon-
nection from the mains (fuse). Even when the blocking
switch is set to “0”, the plant is still live. Electric shocks
can cause fatal injuries and lead to fires.
Behaviour if you smell gas
Danger of explosion if there is a gas leak.
• Do not smoke
• No naked flames
• Avoid the occurrence of sparks
• Do not switch on the light or other electrical appliances
• Open windows and doors
• Close the gas shut-off valve
• Notify the specialist company/installing contractor
• Follow the safety regulations on the gas meter
• Follow the safety regulations of the specialist company
If you smell flue gas
Leaking flue gas represents a risk of poisoning.
• Turn the system off
• Open windows and doors
• Notify the specialist company
Supply air openings
Air inlets and outlets must not be closed. Danger of poiso-
ning due to incomplete combustion if the supply air ope-
nings are closed.
Filling the oil tank
When the oil tank is filled, the burner must always be swit -
ched off with the blocking switch on the boiler. It is only
allowed to be switched on again after waiting for about
2 hours. Filling the oil tank must be monitored by the oil
supplier. We cannot accept any liability for tank overflows.
Initial commissioning / installation inspection
Initial commissioning of a newly installed system may
only be carried out by a heating specialist. Danger of
poisoning due to incorrect commissioning! A full installati-
on inspection must be completed prior to start-up.
Checking the water pressure
Check the water pressure in the system at regular inter-
vals, as described in chapter 9.1 page 81.
Filling the heating system
The replacement water must be of the required quality.
The quality requirements are stated in the installation ins-
tructions in the “Water quality” chapter (Filling and repla-
cement water).

Maintenance, cleaning and inspection
The boiler, burner and calorifier must be serviced regu -
larly by a heating specialist. An important precondition for
economical operation and for maintaining good air quality
is the sound technical condition of your burner system.
The burner must be inspected by a heating specialist
once a year.
Taking out of operation / frost protection
The system must be entered if there is a risk of frost; con-
tact the heating specialist for advice if necessary.
Corrosion protection
Do not use sprays, solvents, chlorine-based cleansing
agents, paint, adhesives etc. in the proximity of the unit.
Under certain circumstances, these substances can
cause corrosion inside the boiler and the flue gas system!
