1.1 USE OF ANTIFREEZE LIQUID
1.2 FEATURES OF UNDER FLOOR
HEATING SYSTEMS
●
If you smell gas:
- do not operate electrical appliances
- extinguish any fires
- close the stopcock upstream of the meter
- open the windows and ventilate the room
- call your local authorised engineer
●
Do not store or use flammable materials near the boiler.
●
Do not obstruct intake/exhaust terminals.
●
To guarantee boiler efficiency and correct operation, it is
imperative to have yearly maintenance, and combustion
analysis every two years, carried out by qualified
engineers, and to have the system booklet prepared, as
stipulated by law.
●
It is forbidden to touch the boiler either with bare feet
and/or with wet parts of the body.
●
In order to clean the outside parts, turn off the boiler turn
off the power at the isolating switch. Clean with a damp
cloth. Do not use detergents and/or harsh liquids, or toxic
products.
●
In order to carry out any work on the boiler, do not mount
it on chairs, stools, ladders or unstable stands.
●
Before carrying out any work on the boiler always turn
the power off at the isolating switch
●
The user is forbidden to carry out any maintenance work
on the boiler that must be carried out by a specialised
engineer.
●
In the case of structural work or maintenance near the
pipes, flue systems or any accessories, switch off the
appliance and, when the work is completed, have the
system checked by a qualified engineer to ensure the
system is in good working order.
1.3 SAFETY ADVICE
In floor systems, the use of plastic pipes without
protection against penetration of oxygen through
the walls can cause corrosion of the system's
metal parts (metal piping, boiler, etc), the forma-
tion of oxides and bacterial agents.
To prevent this problem, it is necessary to use pipes with an
"oxygen-proof barrier", in accordance with standards DIN
4726/4729.
If pipes of this kind are not used, keep the system separa-
te by installing heat exchangers or those with a specific
system water treatment.
In floor systems, a system safety thermostat must
be installed to protect against overtemperature
calibrated at around 45°C (see wiring diagram on
page 14).
TRIANCO is not liable for damage caused to the unit or the
system due to failure to comply with the above.
If antifreeze substances are used in the
system, check carefully that they are compati-
ble with the aluminium that forms the body of
the boiler.
In particular, DO NOT USE ordinary ETHYLENE
GLYCOL, since it is corrosive in relation to aluminium
and its alloys, as well being toxic.
Trianco suggests the use of suitable antifreeze products
and in the correct dose, which will prevent rust and
incrustation taking place.
Periodically check the pH of the water-antifreeze mixtu-
re of the boiler circuit and replace it when the amount
measured is lower than the limit stipulated by the manu-
facturer.
DO NOT MIX DIFFERENT TYPES OF ANTIFREEZE
TRIANCO is not liable for damage caused to the boiler
or system as a result of the use of incorrect antifreeze or
additive substances.
