3 - VARIABLE SPEED CIRCULATION UNIT WITH MAXIMUM FIXED MAXIMUM SPEED MODE (P90 = 1) In this mode the modulating circulation unit works constantly at maximum speed. It is used on plants with a high load loss in which the boiler’s head must be used as much as possible in order to guarantee sufficient circulation (plant flow rate at maximum speed lower than 600 litres per hour). This is used when bottles of mixture are involved, with high flow rates in the circuit downstream.
SECTION 3 - GENERAL REQUIREMENTS (UK) This appliance must be installed by a competent person in accordance with the Gas Safety (Installation & Use) Regulations. 3.1 RELATED DOCUMENTS The installation of this boiler must be in accordance with the relevant requirements of the Gas Safety (Installation & Use) Regulations, the local building regulations, the current I.E.E.
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.
SECTION 3A - GENERAL REQUIREMENTS (EIRE) This appliance must be installed by a competent person in accordance with and defined by, the Standard Specification (Domestic Gas Installations) Declaration (I.S. 813). 3A.1 RELATED DOCUMENTS The installation of this boiler must be in accordance with the relevant requirements of the local building regulations, the current ETCI National Rules for Electrical Installations and the bylaws of the local water undertaking.
SECTION 4 - INSTALLATION 4.1 DELIVERY Due to the weight of the appliance it may be necessary for two people to lift and attach the appliance to its mounting. The appliance is contained within a heavy-duty cardboard carton. Lay the carton on the floor with the writing the correct way up. 4.

• • • • Consideration must also be given to the fact that there is the possibility of a small amount of condensate dripping from the terminal. Ensure that the entire flue system is adequately supported, use at least one bracket for each extension. The entire flue system must be adequately insulated to maintain heat within the flue system thereby reducing the possibility of condensate production.
Fig. 12 4.6 CONNECTING THE GAS AND WATER IMPORTANT - REAR SPACER KIT If you intend to run the pipework vertically behind the appliance, it will be necessary to use the rear spacer kit (part code 435). It will also be necessary to adjust the pitch of the fixing jig to compensate for the increase in the depth of the appliance. The appliance is supplied with a fixing jig that includes service valves (fig. 14). The service valves are of the compression type.
4.6.5 SAFETY VALVE (fig. 14) Connect a discharge pipe to the fixing jig connection and tighten. The discharge pipe must have a continuous fall away from the appliance to outside and allow any water to drain away thereby eliminating the possibility of freezing. The discharge pipe must terminate in a position where any water – possibly boiling – discharges safely without causing damage or injury, but is still visible.
SECTION 5 - COMMISSIONING 5.1 GAS SUPPLY INSTALLATION 5.7 INITIAL LIGHTING Inspect the entire installation including the gas meter, test for tightness and purge. Refer to BS 6891 for specific instruction. Ensure the electrical supply to the appliance is switched on. Press the ON/OFF switch to switch the appliance ON (indicated by active display), ensure any external controls are switched to an ‘ON’ position and are calling for heat.
Info 3 Info 4 displays the set heating temperature displays the set domestic hot water temperature. If you don’t make any selection within 10 seconds, the boiler automatically exits the function; if you want to exit immediately, key. press the 5.9.3 INFORMATION MODE SERVICE It is possible to display information that can be helpful for the Service Engineer. Press for 10 seconds the button : the INF2 will be displayed. Every pressing corresponds to a different information. 5.9.
5.11 REGULATING THE HOT WATER The appliance is fitted with a flow rate restrictor that limits the maximum flow rate that can be drawn through the appliance. The restrictor eliminates the need to manually adjust the DHW flow rate. However if it is felt necessary to further increase or decrease the available flow rate, spare restrictors are included in the accessory pack. The spare flow rate restrictors can be fitted to either increase or decrease the maximum flow rate.
SECTION 6 - SERVICING INSTRUCTIONS 6.1 GENERAL 6.4 COMPONENT REMOVAL PROCEDURE To ensure the continued safe and efficient operation of the appliance, it is recommended that it is checked and serviced at regular intervals. To ensure correct and safe operation of the appliance, it is essential that any worn or failed component be replaced only with a genuine Vokera spare part.

SECTION 7 - CHECKS, ADJUSTMENTS AND FAULT FINDING 7.1 CHECKING APPLIANCE OPERATION When carrying out any repairs or servicing to the appliance, the relevant commissioning procedure must be undertaken to ensure the continued safe operation of the appliance. Particular attention should be made to ensure gas tightness, water tightness, and the electrical integrity of the appliance. you select Comfort button, the boiler should be ready to supply the water at the desired temperature. ● 7.
● ● ● Touch & Go Function: if you don’t wish to keep the Memory function always enabled or if you need hot water to be ready fast besides the usual habits memorized, it is possible to perform the domestic hot water pre-heating only a few moments before the request. Due to Touch & Go function, by turning on and off the tap the instantaneous pre-heating function enables, which prepares hot water only for that request.
7.3 SERVICE MODE & PARAMETERS This boiler is equipped with a new generation of electronic boards, which allow a better personalization by setting / adjusting the machine’s operating parameters, in order to answer the installation and/or usage needs. The programmable parameters are indicated in the table at page 24. The parameters programming must be done with the boiler on OFF position.
