INSTRUCTIONS PRIOR TO INSTALLATION
The following notes and instructions are addressed to fitters to allow them to carry out trouble-free installation. Instructions for
lighting and using the boiler are contained in the ‘Instructions for Users’ section. Installation, servicing and running of domestic
gas-fired systems must be performed by qualified technicians, in compliance with current regulations.
Additionally, bear in mind the following:
• When installing the unit in environments with temperatures lower than 0°C, take the necessary precautions to avoid the
formation of ice in the siphon and in the condensation drain.
• This boiler can be connected to any type of double- or single-pipe convector plate, radiator or thermoconvector. Design the
system sections as usual, though, bearing in mind the available flow-head at the plate, as shown in section 16.
• Do not leave any packaging (plastic bags, polystyrene, etc.) within the reach of children as they are a potential source of
danger.
• Initial lighting of the boiler must be carried out by an authorised Service Engineer, as indicated on the attached sheet.
Failure to observe the above will render the guarantee null and void.
ADDITIONAL PUMP WARNING
If an additional pump is used on the heating system, position it on the boiler return circuit. This will allow the correct operation of
the water pressure switch.
SOLAR WARNING
If the instantaneous (mixed) boiler is connected to a system with solar panels, the maximum temperature of the domestic hot water
entering the boiler must not exceed
60°C
.
Do not leave any packaging (plastic bags, polystyrene, etc.) within the reach of children as they are a potential source of danger.
9. INSTALLING THE BOILER
The template outline is shown in annex
"SECTION" C
at the end of this manual.
After deciding the exact location of the boiler, fix the template to the wall (supplied as an accessory). Connect the system to the
gas and water inlets present on the lower bar of the template. The union support (supplied as an accessory), comprising shut-off
valves and unions, and allowing important maintenance work to be performed without having to drain the entire heating system,
should be installed. If you are either installing the boiler on an existing system or replacing one, as well as the above, fit a settling
tank under the boiler on the system return line in order to collect any deposits and scale circulating in the system after flushing.
After fixing the boiler to the template, connect the flue and air ducts, supplied as accessories, as described in the following
sections. Connect the siphon to a drain trap, making sure the slope is continuous. Avoid horizontal stretches.
Tighten the boiler water connections with care (maximum tightening torque 30 Nm).
Do not lift the boiler exerting pressure on the plastic parts like the siphon and the flue turret.
Before starting up the boiler, fill the water siphon to prevent the fumes from diffusing in the room.
