Appliance characteristics
The Vaillant ecoTEC plus and ecoTEC pro models are
compact, wall-mounted condensing appliances.
ecoTEC plus and pro combination boilers provides both
central heating and domestic hot water, with the domestic hot water supplied directly from the boiler. The boiler will operate automatically to provide domestic hot
water whenever a hot water tap is opened, and automatically adjusts to meet the demand for both central
heating and domestic hot water in the most economical
way.
ecoTEC system boilers provides central heating and
domestic hot water where a separate indirect hot water
cylinder is also incorporated to the system.

2 Safety
2.3 Safety instructions
Always observe the following safety instructions and
regulations.
Danger
Inflammable mixtures of gas and air may
explode.
Do not use or store explosive or easily flammable substances such as petrol or paint in the
same room as the appliance.
Danger
Risk of poisoning and explosion due to a malfunction.
Never put the safety devices out of operation or
tamper with them so as to impair their function.
2.4 Modifications in and around the boiler
No modifications may be made to the following items:
- The boiler
- The gas, water and electrical supply
- The flue system
- The safety valve for the heating water
- Any structural changes around the appliance that
could affect the operational safety of the boiler.
Caution
Inappropriate modifications can cause damage.
Never tamper with the boiler or other parts of
the system.
Never attempt to perform maintenance or
repairs yourself.
- Do not damage or remove seals on components. Only
authorised engineers or our customer service may
removed sealed components.
Danger
Risk of scalding.
The water coming out of the tap can be very
hot (ecoTEC combination boiler only).
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 Installations’, 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 system (see 4.3.2).
Leaks (ecoTEC combination boiler only)
If there is a leak in the water pipes between the appliance 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 operation and heats the boiler circuit to approx. 30 °C.
Note
It cannot be guaranteed that water will circulate 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.
Caution
Risk of damage.
Do not use sprays, solvents, chlorinated cleaning agents, paint, adhesives or similar substances in the vicinity of the appliance. These
substances can cause corrosion, including in
the flue system.
4 Instructions for use ecoTEC
It must be remembered, however, that the boiler will be
automatically switched off by the built in monitoring
devices 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 connected to the electrical supply.
