■Where gas is used as the fuel, close

the main gas shut-off valve and safe-

guard it against unintentional reopen-

ing.

■Isolate the system from the power sup-

ply, e.g. by removing the separate fuse

or by means of a mains isolator, and

check that it is no longer live.

Danger

Hot surfaces and fluids can lead to

burns or scalding.

■Before maintenance and service

work, switch OFF the appliance

and let it cool down.

■Never touch hot surfaces on the

boiler, burner, flue system or pipe-

work.

!Please note

Electronic assemblies can be dam-

aged by electrostatic discharge.

Prior to commencing work, touch

earthed objects such as heating or

water pipes to discharge static

loads.

Repair work

!Please note

Repairing components that fulfil a

safety function can compromise the

safe operation of the system.

Replace faulty components only

with genuine Viessmann spare

parts.

Auxiliary components, spare and

wearing parts

!Please note

Spare and wearing parts that have

not been tested together with the

system can compromise its func-

tion. Installing non-authorised com-

ponents and making non-approved

modifications or conversions can

compromise safety and may invalid-

ate our warranty.

Safety instructions for operating the system

If you smell gas

Danger

Escaping gas can lead to explo-

sions which may result in serious

injury.

■Do not smoke. Prevent naked

flames and sparks. Never switch

lights or electrical appliances on

or off.

■Close the gas shut-off valve.

■Open windows and doors.

■Evacuate any people from the

danger zone.

■Notify your gas or electricity sup-

ply utility from outside the building.

■Have the power supply to the

building shut off from a safe place

(outside the building).

If you smell flue gas

Danger

Flue gas can lead to life threatening

poisoning.

■Shut down the heating system.

■Ventilate the installation site.

■Close doors to living spaces to

prevent flue gases from spread-

ing.

What to do if water escapes from the

appliance

Danger

If water escapes from the appliance

there is a risk of electrocution.

Switch OFF the heating system at

the external isolator (e.g. fuse box,

domestic distribution board).

Danger

If water escapes from the appliance

there is a risk of scalding.

Never touch hot heating water.

Condensate

Danger

Contact with condensate can be

harmful to health.

Never let condensate touch your

skin or eyes and do not swallow it.

Flue systems and combustion air

Ensure that flue systems are clear and

cannot be sealed, for instance due to

accumulation of condensate or other

external causes.

Ensure an adequate supply of combus-

tion air.

Inform system users that subsequent

modifications to the building characteris-

tics are not permissible (e.g. cable/pipe-

work routing, cladding or partitions).

Danger

Leaking or blocked flue systems, or

an inadequate supply of combus-

tion air can cause life threatening

poisoning from carbon monoxide in

the flue gas.

Ensure the flue system is in good

working order. Vents for supplying

combustion air must be non-seala-

ble.

Extractors

Operating appliances that exhaust air to

the outside (extractor hoods, extractors,

air conditioning units, etc.) can create

negative pressure. If the boiler is oper-

ated at the same time, this can lead to a

reverse flow of flue gas.

Safety instructions

Danger

The simultaneous operation of the

boiler and appliances that exhausts

air to the outside can result in life

threatening poisoning due to a

reverse flow of flue gas.

Fit an interlock circuit or take suita-

ble steps to ensure an adequate

supply of combustion air.

The Vitotronic 100, type CC1E control unit is designed

for the control of single boiler systems with a constant

boiler water temperature.

The Vitotronic control unit is factory-configured as a

"Single boiler constant control".

During operation with a constant boiler water tempera-

ture, the boiler provides heating water at a constant

temperature, independent of the outside temperature.

In single boiler systems, central heating and DHW

heating are provided at a constant flow temperature.

The flow temperature corresponds to the set boiler

water temperature.

The Vitotronic control unit can alternatively be config-

ured as a "Boiler in the Cascade":

The Vitotronic control unit is then used to control the

boiler water temperature of a boiler in a multi boiler

system.

Danger

Incorrect wiring can lead to serious injury from

electrical current and result in appliance dam-

age.

Take the following measures to prevent wires

drifting into the adjacent voltage area:

■Route LV leads < 42 V and > 42 V/230 V~

cables separately.

■Only strip the minimum of insulation from

cables as close as possible to the terminals

and bundle tightly to the corresponding termi-

nals.

■Secure cables with cable ties.

When connecting external switching contacts and on-

site components, observe the insulation requirements

of IEC/EN 60335-1.

!Please note

Electronic assemblies can be damaged by elec-

trostatic loads.

Before beginning work, touch an earthed object

such as a heating or water pipe to discharge any

static.
