Installation instructions
Attention!
Before connecting the boiler to the heating
system, thoroughly clean the piping with an
appropriate product in order to eliminate
metallic residue from processing and welding,
oil and grease which could be present and
which, reaching the boiler, could alter its
functioning.
Do not use solvents to wash the system as
they could damage the system and/or its
components.
Failure to comply with the instructions of the
following manual can cause damage to
persons, animals and objects for which the
manufacturer cannot be held responsible.
Attention!
Make sure that there are no mechanical
tension points while connecting the pipes to
avoid the risk of leakage!
Heating flow and return pipes must be connected to the boiler at
the respective fittings as indicated on pages 9, 10, 11, 12 and 13.
For the dimensioning of the heating circuit pipes, you must take
into account pressure drops caused by radiators,
thermostatic valves, radiator stopping valves and by the
configuration of the system.
The laying of the pipes must be designed taking every neces-
sary precaution to avoid air pockets and to facilitate continuous
degassing of the system.
Make sure that the pipes of the water and heating
system are not used as earthing electrodes of
the electric or telephone system.
They are absolutely not suitable for this type
of use. Serious damage could result for the piping, boiler and
radiators in a short amount of time.
Heating system safety valve drainage
Provide a drain pipe with a funnel and a siphon leading to an
appropriate drainage at the heating safety valve. This drainage
must be controlled on sight.
Attention!
If this precaution is not taken, triggering of the
safety valve can cause damage to persons,
animals and objects for which the
manufacturer cannot be held responsible.
Connection of expansion vessel
TRIMAX 3SC boilers are suitable for operating with
forced water circulation both with the expansion
vessel opened or closed.
An expansion vessel is always necessary to
compensate the increase in water volume due
to heating.
The connection pipes of the expansion vessel will start from the
T3 attachment (see DIMENSIONS TABLES) and must have no
shut-off valve.
Connection of filling /drain tap
A specific tap can be connected to the T4 attachment at the rear
of the boiler for filling and draining.
3.10.1 - RECIRCULATION PUMP
TRIMAX 3SC boilers must always operate with forced water
circulation and a minimum return temperature of 50°C.
It is therefore recommended to use a recirculation pump, which
also has an anti-condensation function, installed between the
flow and return connections upstream the mixer valve.
This pump should be dimensioned according to the formula:
Q = P x 22
where
Q = Flow rate in l/hr
P = Nominal output of boiler in kW
and
head 1÷2 m H

3.11 - FILLING THE SYSTEM
Attention!
Do not mix the heating water with incorrect
concentrations of antifreeze or anti-corrosion
substances! This could damage the gaskets
and cause noise during operation.
Ecoflam will not be held liable for damage to persons, animals
or objects due to failure to comply with the instruction
above.
When all system connections have been completed, the circuit
can be filled.
This operation must be performed carefully, respecting the
