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 rectication 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 modications and dama-
ge due to the use of force do not fall under our obligations
under warranty.
Behaviour in case of danger
Cut o󰀨 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 res.
Behaviour if you smell gas
Danger of explosion if there is a gas leak.

If you smell ue gas
Leaking ue gas represents a risk of poisoning.
Turn the system o󰀨

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 lled, the burner must always be swit-
ched o󰀨 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 overows.
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-

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 ue gas system!
