4 Instructions for use ecoTEC / 838402_06

Caution

Inappropriate modifications can cause damage.

Never tamper with the boiler or other parts of

the system.

Never attempt to perform maintenance or re-

pairs yourself.

- Do not damage or remove seals on components. Only

authorised engineers or our customer service may re-

moved sealed components.

Danger

Risk of scalding.

The water coming out of the tap can be very

hot (ecoTEC combination boiler only).

Caution

Risk of damage.

Do not use sprays, solvents, chlorinated clean-

ing agents, paint, adhesives or similar sub-

stances in the vicinity of the appliance. These

substances can cause corrosion, including in

the flue system.

Installation and setting

Important

The appliance must be installed and serviced by

a competent person as stated in the Gas Safety

(Installation and Use) Regulations 1998. In IE,

the installation must be in accordance with the

current edition of I.S.813 ‘Domestic Gas Instal-

lations’, the current Building Regulations and

reference should be made to the current ETCI

rules for electrical installation.

Caution

The appliance may only be operated with its

case properly and permanently closed.

Otherwise, in unfavourable conditions, material

damage or even injury or death can result.

Filling pressure of the heating system

Regularly check the filling pressure of the heating sys-

tem (see 4.3.2).

Leaks (ecoTEC combination boiler only)

If there is a leak in the water pipes between the appli-

ance and the taps, immediately turn off the cold water

service valve and have your engineer repair the leak.

Frost protection

Your boiler is equipped with a frost protection function:

If the heating water temperature drops below 5 °C when

the main switch is ON, then the boiler goes into opera-

tion and heats the boiler circuit to approx. 30 °C.

Note

It cannot be guaranteed that water will circu-

late throughout the entire heating system.

If the boiler is not operated for several hours during

very cold weather there is therefore the possibility of

the system freezing.

Please ensure that if you are absent during a period of

frost the central heating remains in operation and all

rooms are kept above freezing point.

It must be remembered, however, that the boiler will be

automatically switched off by the built in monitoring de-

vices if certain faults occur, e.g. interruption in the gas

or electricity supply or faults in the flue gas system. To

overcome this possibility you can drain both the central

heating system and boiler.

Note

Frost protection and monitoring devices can

only function when the main switch of the unit

is set to the “I” position and the boiler is con-

nected to the electrical supply.
