INSTRUCTIONS FOR THE INSTALLER

2.
If we are careful not to bend the tabs
more than 45º, we can extract the frame,
even once the apparatus is embedded.
Figure No.13 -
Close up of the bent tab
In
any
case,
Lacunza
always
recommends adhering the frame to the
wall by its 4 sides using high-temperature
silicon. The frame is flexible and therefore
it can be adapted to any imperfections on
the wall.
2.3.9.
Turbine-potentiometer connection
These are the connection instructions in
order to control the ventilator system using
the supplied potentiometer:
Figure No.14 -
Connections to be carried
out in the potentiometer
WARNING: the operating temperature
of the potentiometer supplied by Lacunza
is from 0 to 40ºC. Particular care should
be taken when choosing where it will be
positioned so that it is not damaged by
temperatures above 40ºC. Insulate the
potentiometer correctly so as to avoid this
problem.
Read the potentiometer instruction
manual.
Due to the movement of the ventilators,
this apparatus may vibrate structures that
come into contact with it. These vibrations
may cause noise. To prevent these
vibrations from occurring, a damping
element that is also resistant to high
temperatures (up to 200ºC) should be
positioned between the base of the
apparatus and the supporting structure.
2.4.
Chimney flue
The chimney flue must comply with
present standards on the installation of
chimneys.
In rooms equipped with Controlled
Mechanical Ventilation, the ventilation
outlet must never be connected to the
flue.
The appliance must always have its own
chimney flue, never sharing a chimney flue
with another appliance.
2.4.1.
Type of flue
The flue must be made of special
material designed to resist the products of
combustion (e.g. stainless steel, enamelled
steel, etc.).
Non-central-heating
appliances
(without back boiler) require an insulated,
double-sleeve flue only on those sections
that run outdoors or through cold areas.
Single piping can be used inside the
building, the heat of the gases serving to
heat rooms, insulating only those sections
where excess temperature may cause
damage.
