The initial start-up and matching of

the control unit to local conditions and

the structural characteristics of the

building must be carried out by your

heating contractor.

Your heating system is pre-set at the factory

Your combi boiler is ready to provide

both central heating and hot water

after installation. Your system boiler

will provide both heating and hot

water providing a cylinder is installed.

Your heating system is ready for use.

You may change the factory settings

in accordance with personal require-

ments.

Note

All data is saved in case of power fail-

ure.

The Vitodens 100 is certified to com-

ply with the requirements of the rele-

vant European Directives (90/396/

EEC, 73/23 EEC and 92/42/EEC) for

use in Great Britain and Ireland with

gas category I2H (G20 with a gov-

erned gas supply at 20 mbar (8 in.wg)

inlet pressure).

The appliance classification is either

C13x or C33x depending upon whether

a horizontal or vertical flue terminal is

used.

General Description

The Vitodens 100 is a fully automatic,

wall mounted, fan assisted balanced

flue gas combination or system boiler

for use with natural gas (G20) at 20

mbar (8 in.wg) supply on sealed sys-

tems only.

The unit provides central heating at

outputs between 8.0 kW to 24.0 kW/

30.0 kW. If required, the central heat-

ing heat output can be range rated to

suit the system requirements.

Heat output is automatically con-

trolledaccordingtodemand(inboth

domestic hot water and central heat-

ing mode). Note that hot water is

always given priority.

Changing room temperature

In addition to the boiler control unit, a separate room temperature controller

must be installed in one of the living rooms to comply with part L of the building

regs if the heating system is to be regulated in accordance with the required

room temperature.

Make adjustments using the appropri-

ate operating instructions.

Please also note:

It ist not recommended that thermo-

static radiator valves are intalled in

the same room as the controller.

If thermostatic radiator valves are

installed in the room where the con-

troller ist fitted they mus be fully open.

The initial start-up and matching of the control unit to local conditions and struc-

tural characteristics of the building, must be carried out by your heating contrac-

tor.

Before you switch ON a heating system which has been switched OFF for

longer periods, it would be advisable to contact your local heating contractor.

1. Switch ON the mains power.

Your heating system and, if

installed, your room temperature

controller Vitotrol 100 or similar

programmable room thermostat are

now ready to operate.

2. Control the pressure of the heating

system by setting the rotary selec-

tors to"tw "and"tr"to"9". The

system pressure is displayed.

Minimumsystempressure1.0

bar.

Please contact your heating con-

tractor if the system pressure is too

low. Information regarding topping

up the system can be found in the

installation and service instruc-

tions.

Heating system start-up

Start-up and shutdown

5592 487 GB

Vitodens can be operated in the following modes: "heating" or "hot water".

Heating mode

If the room temperature controller

Vitotrol 100, or similar programmable

room thermostat, is connected, then

the room temperature is controlled

from there.

Observe the separate operating

instructions.

Should the room temperature control-

ler not produce sufficient heat (e.g.

when it's very cold), the heating tem-

perature can be changed at the rotary

selector "tr".

DHW heating - combi

In the event of a demand for hot

water, the appliance will detect water

flow and initiate the ignition

sequence. The fan (and pump) will

start and the boiler will light.

If the hot water demand is near to the

maximum design flow rate the boiler

will run continuously at full output until

the tap is closed or the flow rate is

reduced, the heat input will be

reducedtomaintainasteadypreset

temperature at the tap.

Hot water is available almost instanta-

neously from the boiler, but the final

outlet temperature and the delay in

reaching full temperature will depend

ontheflowrateandthedistancefrom

the boiler to the tap.

When the tap is closed, the boiler will

return to heating mode if there is a

demand for heating, otherwise the

boiler will shut down until the next

demand for heating or hot water.

Heating

Switching ON:

Set rotary selector "tr"tothe

desired heating temperature.

The display "r" indicates when room

temperature has been reached.

Switching OFF:

Turn heating rotary selector"r"to

"r".

Operating modes

Settings

5592 487 GB

Operation with integral instantaneous water heater:

Select the DHW temperature in accordance with your personal preferences (e.

g. for showers).

Switching ON:

Set rotary selector "tw"tothe

desired DHW temperature.

The display "w" indicates when DHW

temperature has been reached.

Switching OFF:

Turn DHW rotary selector"r"to

"r".

DHW (system boiler only)

When in operation with separate a DHW cylinder, DHW temperature is regu-

lated at the temperature control on the DHW cylinder.

Checking the heating temperature

During operation, heating water tem-

perature is constantly displayed.

Checking the system pressure

1. Turn both the rotary selectors"tr"

and "tw" fully "9" anti-clockwise.

The display now shows the actual

system pressure, for instance 1.0

bar.

2. Return both rotary selectors to their

original positions.

Note

The display will flash if the system

pressure falls below 0.6 bar. In this

instance, please notify your heating

contractor. Information regarding top-

ping up the system pressure can be

foundintheinstallationandservice

instructions.

Switch OFF the equipment if you don't want to use the boiler for a few days.

Turn both rotary selectors to "9".

Boiler frost protection is active.

Heating system shutdown

Shut down your heating system completely, if it will not be needed for longer

periods of time (several months).

Before you switch your heating system OFF for longer periods, it would be advi-

sable to contact your local heating contractor. Your heating engineer will take

any necessary measures, e.g. for frost protection of the system or to preserve

the heating surfaces.

1. Close the main gas shut-off valve

and safeguard against

unauthorised reopening.

2. Switch OFF the mains power.

Now the system is idle.

Please note that the system is no

longer frost protected.

Inspection and maintenance

To ensure continued efficient opera-

tion of the appliance, it is recom-

mended that it is checked and

serviced at regular intervals. The fre-

quency of servicing will depend upon

the particular installation conditions

and usage but in general once a year

should be adequate. It is the law that

any service work must be carried out

by a competent CORGI registered

engineer.

Cleaning

Repairs

5592 487 GB

Along with using a modern heating system, you can save additional energy by

your own actions.

For this, the following measures will help you:

&Correct ventilation.

If windows are left open Aclose

thermostatic radiator valves Bto

prevent incorrect heat demand.

&Do not overheat.

Endeavour to reach a room tem-

perature of 20 ºC; every degree of

room temperature reduction saves

up to 6 % of your heating bills.

&Close roller shutters (where

installed) at dusk.

&Adjust thermostatic radiator

valves Bcorrectly.

&Do not cover radiators Cor ther-

mostatic radiator valves B.

&Utilise the setting options offered by

control unit D.

&Controlled DHW consumption: A

shower generally uses less energy

than a full bath.
