1.5 Instructions for operating safety
Before working on the heating system
• Only authorised and trained heating engineers should work on the heating system (e.g. set-up, connection and initial start-up).
• Switch off the mains supply before starting any work on the heating system and secure it against unintentional switch-on.
Electrical installation
• Electrical installations may only be carried out by qualified electrical technicians under observance of the relevant electrical
guidelines and the regulations of the electric utilities company.
• Compare the mains voltage (230 V, 50 Hz) indicated on the nameplate with the supply voltage before connecting to the mains.
Unit installation room
• Operate the oil condensing boiler only if sufficient combustible air supply is guaranteed. If operating the oil condensing boiler
independently of the ambient air with an air/flue system (LAS) with dimensions according to ROTEX-Standard, this is
automatically guaranteed and there will be no further conditions required of the unit installation room.
• Make sure that there is a supply air opening to the open air, of at least 150 cm
2
with ambient air dependent operation.
• Do not operate the oil condensing boiler dependent on ambient air in rooms with aggressive vapours (e.g. hair spray, perchlo-
roethylene, carbon tetrachloride), strong dust formation (e.g. workshop) or high atmospheric humidity (e.g. laundry).
• Strictly keep the minimum distances to walls and other objects (see chapter 3.1).
Heating system
• Create a heating system according to the safety requirements of EN 12828, as an open or closed heating system.
• Note that the safety valves must comply with DIN EN ISO 4126-1 and be type tested. The safety valves must be installed
in the safety flow.
• Check the correct installation of the temperature sensor and safety temperature controller before the initial start up.
• Always operate the oil condensing boiler with the sound insulation hoods closed.
Fuel
• Use only the approved heating oils as fuel (see chapter 11 "Technical data").
Instructing the user/owner
• Before you hand over the heating system, explain to the owner how he/she can operate and check the heating system.
• Make a record of the handover by filling out and signing the installation and instruction forms jointly with the user/owner.
