Safety instructions explained

DangerThis symbol warns against therisk of injury.

! Please noteThis symbol warns against therisk of material losses and envi-ronmental pollution.

NoteDetails identified by the word "Note" con-tain additional information.

Target group

These instructions are exclusivelydesigned for qualified personnel.■ Work on gas appliances must only be

carried out by a qualified gas fitter.■ Work on electrical equipment must

only be carried out by a qualified elec-trician.

Regulations

Observe the following when working onthis system■ all legal instructions regarding the pre-

vention of accidents,■ all legal instructions regarding envi-

ronmental protection,

■ the Code of Practice of relevant tradeassociations,

■ all current safety regulations asdefined by DIN, EN, DVGW, TRGI,TRF, VDE and all locally applicablestandards.

Working on the system

■ Isolate the system from the power sup-ply and check that it is no longer 'live',e.g. by removing a separate fuse or bymeans of a mains isolator.

■ Safeguard the system against unau-thorised reconnection.

■ When using gas as fuel, also close themain gas shut-off valve and safeguardagainst unauthorised reopening.

Vitodens 200-W, WB2C

Set up for operation with natural gas E and LL. For conversion to LPG P (without conversion kit), see the service instructions.

Conversion for other target countriesThe Vitodens 200-W should generally only be delivered to those countries specifiedon the type plate. For deliveries to alternative countries, an approved contractor, onhis own initiative, must arrange individual approval in accordance with the law of theland.

Multi-boiler systemIn connection with the installation of a multi-boiler system observe the installationinstructions of the multi-boiler system accessories.For installations in a multi-boiler system, generally the boiler coding card needs to bereplaced (see page 16).

NoteThis boiler (protection IP X4 D) isapproved for installation in wet roomsinside protection area 1 according toDIN VDE 0100 [Germany], if hosedwater can be prevented.Observe the requirements ofDIN VDE 0100 [or local regulations].

1. Prepare the water connections. Flushthe heating system thoroughly.

2. Prepare the gas connection accord-ing to TRGI or TRF [or local regula-tions].

3. Prepare the electrical connections.■ Power supply cable: NYM-

J 3 x 1.5 mm2, fuse max. 16 A,230 V~.

■ Accessory cables: NYM with therequired number of conductors forthe external connections.

■ Allow all cables in area "H" to pro-trude 1200 mm from the wall.

2. Carry out a tightness test.

NoteFor the tightness test, use only suita-ble and approved leak detectingagents (EN 14291) and devices.Leak detecting agents with unsuita-ble constituents (e.g. nitrites, sul-phides) can lead to material dam-age.Remove residues of the leak detect-ing agent after testing.

! Please noteExcessive test pressure maydamage the boiler and the gasvalve. Max. test pressure 150 mbar.Where higher pressure isrequired for tightness tests,separate the boiler and thegas valves from the gas sup-ply pipe (undo the fitting).

3. Vent the gas line.

DangerIncorrect core terminationcan cause severe injuriesand damage to the equip-ment.Take care not to interchangewires "L1" and "N".

■ Install an isolator in the powersupply line that simultaneouslyisolates all non-earthed conduc-tors from the mains with at least3 mm contact separation.We additionally recommendinstalling an AC/DC-sensitiveRCD (RCD class B ) forDC (fault) currents that can occurwith energy-efficient equipment.

■ Max. fuse rating 16 A.

lH ■ Power supply accessories (230 V/50 Hz). Where the boiler is instal-led in a wet area, the connectionof accessories to the power sup-ply must not be carried out at thecontrol unit. The power supplyconnection for accessories can bemade immediately at the controlunit, if the boiler is installed out-side wet areas. This connection isdirectly controlled with the systemON/OFF switch (max. 3 A).
