INSTRUCTIONS FOR THE INSTALLER 9
2.
On non-central-heating appliances
(without back boiler), Lacunza does not
recommend enveloping the outside of
appliances with insulation.
¡Warning! : The installer must fit the
necessary inspection accesses (trap doors,
hatches, etc.) so that everything inside the
hood that may need maintenance work or
replacement can be accessed at any time,
e.g. counterweight system, hydraulic
components,
heating circuit safety
components.
2.3.6. Connection to the flue
The appliance must be connected to the
chimney flue using special piping designed
to resist the products of combustion (e.g.
stainless steel, enamelled steel, etc.).
To connect the flue to the socket flange,
insert the piping inside the flange and seal
the joint with fire sealant or fire cement to
make it completely airtight.
The installer must ensure that the pipe
connected to the appliance is well secured
and there is no chance of it coming free
from its housing (e.g. as a result of
dilatation due to temperature, etc.).
2.3.7. Piping air to other rooms
It is possible to pipe some of the heat
generated to other rooms in the house
using the appliance. This does not mean
that the appliance works more efficiently,
but it does mean that the heat it creates is
distributed better. For this purpose, in the
top surface of the appliance there are 4
potential hot-air outlets with diameters of
120mm on the top shell of the appliance.
Pipes can be fitted from these outlets to
other rooms. If you intend to do this, bear
the following points in mind.
•
Do not break the scored steel
circles completely. Simply bend them in
order to facilitate the conduction of
heat to the pipe.
•
The air ducts must always be heat
insulated and smooth inside (not
corrugated).
•
The pipes must always have an
upward slant to facilitate movement by
air density.
•
On routes with a lot of load loss (a
lot of retention), air movement can be
forced along the ducts using a motor or
fan, provided that it is designed to
withstand such temperature conditions.
Bear in mind that air ducts mean that
noise travels more easily from one room to
another.
The following table shows the heat
output of the air from the hot-air outlets
with the appliance working at Nominal
Heat Output:

Figure No.6 - Table showing heat output of the
air leaving the appliance
Note: The values shown in the above
table were measured at the appliance
output point and based on tests performed
at nominal heat output and maximum fan
speed.
All hot-air ducts lose heat, meaning that
the heat output obtained at the end of
piping always depends on its design.
