a

Do not allow children or infirm persons to operate 
this 

THERMITAL THE/TG 3S

 boiler unsupervised.

 

a

Do not operate any electrical devices or equipment, 
including switches or domestic appliances, etc., if 
you can smell fuel or fumes. If you detect any suspi-
cious smells:

-  Ventilate the room by opening all doors and win-

dows.

-  Close the fuel shut-off cock.
-  Report the fault immediately to the 

THERMITAL

 

Technical Assistance Service or a professionally 
qualified heating engineer.

 

a

Do not touch the boiler while barefoot or wet.

 

a

Never clean or service the boiler without first dis-
connecting it from the mains electricity supply 
by turning the main power switch and the control 
panel switch OFF.

 

a

Do not tamper with or adjust the safety or control 
devices without prior authorisation and instructions 
from the boiler’s manufacturer.

The boiler is delivered in separate crates. Check 
that it is complete, undamaged and as ordered as 
soon as you receive it. Report any discrepancies or 
damage to the dealer who sold it.

The

 

THERMITAL THE/TG 3S

 

boiler must be 

installed by a legally qualified heating engineer. 
On completion of the installation, the installer must 
issue the owner with a declaration of conformity 
confirming that the installation has been completed 
to the highest standards in compliance with the 
instructions provided by 

THERMITAL

 in this instruc-

tion manual, and that it conforms to all applicable 
laws and standards.

The boiler must only be used for the purpose speci-
fied by 

THERMITAL

 and for which it is designed. 

The manufacturer declines all responsibility, con-
tractual or other, for damage to property or injury to 
persons or animals caused by improper installation, 
adjustment, maintenance or use.

If you notice any water leaking from the boiler, dis-
connect it immediately from the mains electricity 
supply, shut off the water supply, and notify your 
local 

THERMITAL

 Technical Assistance Centre or a 

qualified heating engineer immediately.

The operation of any appliance that uses fuel, electrical power and water demands that a number of fundamental safety 
precautions be respected.

Periodically check that operating pressure in the 
water circuit is 

over 1 bar

 but below the maximum 

limit specified for the boiler. If this is not the case, 
contact 

THERMITAL

’s Technical Assistance Service 

or a professionally qualified heating engineer.

If the boiler is not going to be used for an extended 
period of time, contact 

THERMITAL

’s Technical 

Assistance Service or a qualified heating engineer 
to have it prepared for shut-down as follows:

- Switch the boiler OFF at the control panel and at the 

mains power switch.

- Close the fuel cock and heating circuit water cock.
- Drain the central heating circuit if there is any risk of 

freezing.

Drain the central heating circuit if there is any risk of 
freezing

This instruction manual is an integral part of the boil-
er. It must be kept safe and must ALWAYS accom-
pany the boiler, even if it is sold to another owner or 
transferred to another user or to another installation.

 

If you damage or lose this manual, order a replace-
ment immediately from your local 

THERMITAL

 

Technical Assistance Centre.

 

a

Never pull, disconnect, or twist the electrical cables 
coming from the boiler even if it is disconnected 
from the mains electricity supply.

 

a

Do not obstruct or restrict the vents in the room 
where the boiler is installed. Adequate ventilation is 
essential for correct combustion.

 

a

Do not expose the boiler to the elements. Do not 
install the boiler outdoors. It is not designed to work 
outdoors and is not fitted with the necessary auto-
matic anti-frost systems to do so.

 

a

Do not switch the boiler off if outdoor temperature 
drops below ZERO (risk of freezing).

 

a

Do not store containers of flammable substances in 
the room where the boiler is installed.

 

a

Do not dispose of packaging material into the envi-
ronment, or leave it within the reach of children, 
since it can become a potential hazard. Dispose of 
packaging material in compliance with applicable 
legislation.
