2.4 Hydraulic connections
Never support the heater by the water and gas connections. Make the
connections in accordance with the dimensions and connections in section
4.1.
There are labels on the unit identifying the 1/2" water inlet pipe (white) and the 3/4" gas
inlet pipe (yellow).
fig. 10 - Connection cards
If the water hardness is over 25ºFr (1ºF=10ppm CaCO3), the water must be
treated to avoid possible deposits on the unit.
2.5 Gas connection
Before making the connection, check that the unit has been prepared
to operate with the right type of fuel, and carefully clean the gas pipes
to remove any residue that might hinder correct operation. Make this
connection in accordance with the dimensions and connections in
section 4.1.
1 Connect the corresponding gas inlet (see section 4.1) in accordance with current
regulations in the country where the heater is being installed.
2 Connect using a rigid metal pipe (connection to a gas supply network) or a
flexible, continuous stainless steel pipe (LPG installation), adding a shut-off valve
between the installation and the unit (AS CLOSE AS POSSIBLE TO THE UNIT).
3 Once the connection to the gas network is complete, check that all gas connections
are tight. For this purpose, a tightness test must be performed. To avoid damage to
the unit due to excess pressure, leave the gas inlet valve closed.
Check that the supplied pressure and gas delivery values are those indicated for the
unit's consumption. See the technical data table (section 4.4).
In installations with an approved flexible pipe for LPG, pay special
attention to the following:
• The pipe must comply with applicable regulations.
• Avoid areas with heat emissions.
• Prevent the pipe from bending or being pinched shut.
• The connections on both sides (gas valve and other components) must comply with the
regulations of the country where the heater is installed.
2.6 Electrical connections
The unit's electrical safety is only ensured when it's effectively grounded,
as established by safety standards. Have qualified personnel check the
effectiveness and suitability of the grounding system, as the manufacturer
will not be liable for any damage caused by a lack of grounding on the
installation.
The unit's power cable may not be replaced by the user. If the cable is damaged, turn off
the unit and call the authorized technical support center to have it replaced. To replace
the cable, use only the 3x0.75mm
HAR H05 VV-F cable, with a maximum outer diameter
2
of 8 mm.
2.7 Air and flue gas ducts
This is a type C unit, with a sealed chamber and forced draft. The air inlet and
flue gas outlet must be connected to systems such as those indicated below.
The unit is approved for operation with all Cxy flue configurations shown on the technical
data card (some of these are used as examples later). However, some configurations
may be limited or prohibited by local laws, standards, or regulations. Before performing
the installation, carefully check and observe any such restrictions. Also observe all
provisions regarding placement on walls and/or ceilings and minimum distances to
windows, walls, air vents, etc. (section 2.2).
Before performing the installation, verify the diaphragm to be used and make sure it
does not exceed the maximum permitted length by making a simple calculation:
1. Design the entire separate flue system, including the accessories and outlet terminals.
2. See Table 1 and determine the losses in m
component, depending on its assembly position.
3. Make sure the total sum of the losses is less than or equal to the maximum length
indicated on Table 2 (see section 2.7.4).

2.7.1 Diaphragm
For the unit to operate correctly, the included diaphragms must be installed. Make sure
the correct diaphragm has been installed (when used), and that it's properly installed.

2.7.2 Condensate collection accessories (optional)
For vertical pipe installations, type C3x, C5x, B2x, and C1x , it is
advisable to install the condensate collection accessory.
•
For connection to a Ø60/100 coaxial pipe with condensate collection (010023X0).
