Please ensure that this appliance has been properly connected to the electrical supply by means of a double pole isolator or un-switched socket, and that the correct size of fuse (3 amp) has been fitted.

WARNING:

THIS APPLIANCE MUST BE EARTHED!

GUARANTEE REGISTRATION CARD

Please take the time to fill out your guarantee registration card. The completed warranty card should be posted within 30 days of installation.

BENCHMARK LOG BOOK

The Benchmark Log Book is supplied with your boiler. This important document must be completed during the installation/commissioning of your boiler.

All CORGI Registered Installers carry a CORGI

ID card and have a registration number. Both shoulf be recorded in your Benchmark Log Book. You can check your installer by calling CORGI direct on 01256 372300. Failure to install and commission the appliance in accordance with the manufacturers instructions may invalidate the warranty. This does not affect your statutory rights.

HOW DOES IT WORK?

Your Syntesi e boiler is a combined central heating and hot water boiler. The Syntesi e supplies heated water to your radiators and provides hot water when a hot water outlet is opened.

Your Syntesi e boiler can be controlled by several different types of controls such as:

● Integral time clock

●

External time clock

● Vokera remote-control

● Programmable room thermostat

It’s therefore necessary to ensure that these instructions are read in conjunction with the instructions supplied with the relevant control.

The Syntesi e lights electronically and does not have a pilot light.

In the unlikely event of a fault developing with your boiler, the supply of gas to the burner will be terminated automatically.

ADDITIONAL FEATURES

Your

Syntesi e

boiler includes some of the latest features that have been designed to ensure continued safety and reliability of the appliance.

These include:

● appliance frost protection

● hot water pre-heat

●

pump, valve actuator & fan anti-block

● diagnostic fault codes

● LED status indicator

● digital display

FROST PROTECTION

Your

Syntesi e

boiler will automatically operate to minimise the risk of frost damage to the boiler itself. The frost protection device will be disabled should the power supply to the boiler be disrupted.

HOT WATER PRE-HEAT

The

Syntesi

’s pre-heat facility ensures that the boiler responds quickly to any hot water requests.

PUMP, ACTUATOR, & FAN ANTI-BLOCK

When the boiler has not been used for more than

24 hours, the pump, fan & valve actuator, are energised for a few seconds to ensure that they does not stick or jam. This function will be disabled should the power supply to the boiler be disrupted.

DIAGNOSTIC FAULT CODES

In the unlikely event of a fault developing, the boiler displays a unique fault code that helps identify where the fault lies.

LED STATUS INDICATOR

The Syntesi e is equipped with an LED status indicator that gives a visual indication of whether the boiler is working normally or has developed a fault.

DIGITAL DISPLAY

The digital display shows the current temperature of the hot water or heating outlet (depending on mode of operation). In addition, it also displays a unique fault code in the unlikely event of the boiler malfunctioning.

GETTING STARTED

2.1

2.2

BEFORE SWITCHING ON

Before switching the appliance on please familiarise yourself with:

● how to isolate the appliance from the gas, water

●

● and electricity supplies how to check and top-up – if necessary – the system water pressure the time clock or boiler control

●

● any external thermostats and their functions the appliance controls.

APPLIANCE CONTROLS (see fig. 1)

The appliance controls are concealed behind the front flap. To gain access to the controls simply press the top centre of the flap, release and pull downwards.

The appliance has a mode selector switch, variable thermostats for controlling the temperature of the heating flow outlet and the hot water outlet, system pressure gauge and an aperture for an integral clock. The mode selector switch has three positions:

●

● hot water only off

● heating & hot water

The variable hot water thermostat allows you to set the temperature of the water to your hot water taps between 37.5

°

C (min) and 65

°

C (max).

The appliance will have been commissioned by your installer to deliver hot water at both a reasonable temperature and flow rate.

Should you wish to increase the temperature of the hot water and the hot water thermostat is already set at maximum, simply reduce the flow of water as it comes out of the tap. Please consult your installer for further advice if required.

The variable heating thermostat allows you to set the temperature of the water to your radiators between 40 ° C (min) and 80 ° C (max).

The pressure gauge shows the current pressure of the system, the gauge should be set between

1 and 1.5 bar. When the appliance is operating the gauge may rise or fall slightly, this is quite

2.3

normal. The minimum permissible level for the safe and efficient operation of the appliance is

0.5 bar. Should the pressure fall below 0.5 bar, the boiler shuts off automatically.

Depending on the type of controls specified by your installer you may have an integral Vokera time clock or the Vokera remote control fitted, if so, supplementary instructions can be found at the back of this booklet. If an external time clock has been fitted, please refer to the instructions supplied with such.

LIGHTING THE BOILER

Ensure the gas and electrical supplies to the boiler are turned on.

Turn the mode switch to the ‘heating & hot water’ position. The status indicator should be ‘Green’ if the status indicator is flashing ‘Red’ refer to 3.2.

Refer to the particular instructions for the type of time clock or control fitted and ensure there is a demand for heating. If there is a room thermostat you should ensure that this is also calling for heat.

When there is a demand for heating via the above controls the boiler will go through an ignition sequence, whereby the burner will light.

If the appliance fails to ignite during the ignition sequence, allow a period of two minutes before re-setting.

To adjust the output temperature of the appliance turn the thermostat knob clockwise to increase or anti-clockwise to decrease.

When the appliance reaches the set temperature, the burner will go off for minimum period of approximately 3 minutes.

When the time clock or external thermostats heating request has been satisfied, the appliance will switch off automatically.

When the mode selector switch is in the hot water only or heating & hot water position, the boiler will light to supply hot water whenever a hot water outlet (tap) is opened.

Periodically the appliance will light on minimum output as a function of the pre-heat facility.

e

HOW TO.....

3.1

HOW TO TOP-UP THE SYSTEM PRESSURE (fig. 2)

The system pressure must be checked periodically to ensure the correct operation of the boiler.

The needle on the gauge should be reading between 1 and 1.5 bar when the boiler is in an off position and has cooled to room temperature. If the pressure requires ‘topping-up’ use the following instructions as a guide.

● Locate the filling valve connections (below the

● boiler).

Attach the filling loop to both connections.

●

●

Open the isolating valve (Left) slowly.

Move the filling valve (Right) slowly to the fill position (fig. 3) until you hear water entering the system.

●

●

●

Move the filling valve back to its normal position (fig. 3) when the pressure gauge (on the boiler) reads between 1 and 1.5 bar.

Close the isolating valve

Remove the filling loop from the connections.

3.2

HOW TO RESET THE APPLIANCE

When the LED status indicator is flashing red, the appliance will require to be reset manually.

Using the mode selector switch, turn it to the OFF/

RESET position, then turn it back to the ‘hot water only’ or ‘heating & hot water’ position (see also

3.3).

Allow a period of two minutes to elapse before turning the mode switch to the reset position.
