3.6.8 FREQUENT FILLING

Frequent filling or venting of the system may be indicative of a leak.

Care should be taken during the installation of the appliance to

ensure all aspects of the system are capable of withstanding

pressures up to at least 3 bar.

3.7 ELECTRICAL SUPPLY

The appliance is supplied for operation on 230V @ 50Hz electrical

supply; it must be protected with a 3-amp fuse. The method of

connection to the mains electricity supply must allow for complete

isolation from the supply. The preferred method is by using a

double-pole switch with a contact separation of at least 3,5mm (3°

high-voltage category). The switch must only supply the appliance

and its corresponding controls, i.e. time clock, room thermostat, etc.

Alternatively an un-switched shuttered socket with a fused 3-pin

plug both complying with BS 1363 is acceptable.

3.8 TIMBER FRAMED BUILDINGS

If the appliance is to be fitted in a timber framed building, it should

be fitted in accordance with the Institute of Gas Engineers publication

(IGE/UP/7) ‘Guide for Gas Installations in Timber Frame Buildings’.

3.9 INHIBITORS

Vokèra recommend that an inhibitor - suitable for use with

aluminium heat exchangers - is used to protect the boiler and

system from the effects of corrosion and/or electrolytic action. The

inhibitor must be administered in strict accordance with the

manufacturers instructions*.

*Water treatment of the complete heating system - including the

boiler - should be carried out in accordance with BS 7593 and the

Domestic Water Treatment Association’s (DWTA) code of practice.

3.10 SHOWERS

If the appliance is intended for use with a shower, the shower must

be thermostatically controlled and be suitable for use with a

combination boiler.
