INSTRUCTIONS FOR THE INSTALLER 14
2.
IMPORTANT: We recommend that a
switch be fitted between the power hose
and the power socket with which to be
able to cut the power supply to the fan
manually and not by means of the
potentiometer switch.
The potentiometer has a safety system
which starts the fan when the thermostat
probe detects temperatures of more than
50ºC even though the potentiometer is set
to OFF; regardless of whether it is in
automatic or manual mode. If the
appliance is no longer going to be loaded
with wood (e.g. when you go to bed) and
the noise of the fan may prove annoying, it
can be switched off by cutting the power
supply to it using the switch suggested
above.
Earth the system on the plastic terminal
strip supplied with the potentiometer.
WARNING: the operating temperature
of the potentiometer supplied by Lacunza
on ITACA C/V models (with fan) is from 0
to 40ºC. Be particularly careful when
choosing the place to fit it so that it
cannot be damaged by temperatures of
over
40ºC. Fully insulate the
potentiometer in order not to encounter
this problem.
Read the potentiometer instruction
manual.
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.
If the chimney is constructed, then it is
necessary to pipe and insulate it to ensure
correct updraught.
The diameter of the pipe must be the
same as the diameter of the flue socket on
the appliance over its entire length in order
to ensure correct operation.
The flue must prevent the entry of
rainwater.
The flue must be clean and airtight over
its entire length.
The flue must be at least 6m tall and the
chimney cap must not hinder the free
release of gases.
If the flue tends to suffer from
downdraught, then it is necessary to fit an
effective anti-downdraught cowl, a static
cowl or a smoke extraction fan, or reshape
the chimney.
Never make 90º bends, due to the great
loss of draught they cause, and reduce 45º
bends down to an absolute minimum. Each
45º bend is equivalent to a 0.5m reduction
in flue length. Horizontal flue sections
should not be installed because they cut
updraught a great deal.
If the flue draws at more than 20 Pa on
12Pa appliances and more than 25Pa on
17Pa appliances, then an effective damper
