Clearances shall provide provision for service access and protection from combustible
surfaces. Minimum clearances from combustible surfaces shall be 50mm at sides, 300mm
from top and 300mm from bottom.
ENSURE THAT THE AIR ENTRY IS NOT OBSTRUCTED BY ADJACENT CABINETS
OR OTHER STRUCTURES.
2.2 Installation
If our accessories are used to install the boiler, read the instructions enclosed carefully.
After choosing the suitable position to install the boiler, fit the installation template (see fig.
2). It must be oriented perpendicularly by means of a spirit or a plumb line. The template
shows the two holes which serve to fasten the boiler to the wall. They are to be drilled with
a ∅ 12 mm drill bit. Insert the supplied dowels and ensure that the hooks are fit. Mark also
the position of the hydraulic and gas connections holes on the wall. The supplied dowel
can ensure a firm hold only if inserted properly. In the event that walls do not provide the
apparatus with a steady support, take the adequate countermeasures.
2.3 Hydraulic connections
The hydraulic connections must be performed in a rational manner by following the
indications of the boiler template (fig. 2). Optional is provided the kit 10 SILE including all
the compression fittings can be used, supplied on request. The boiler safety valve drain
must conduct to a secure draining tube. In absence of this tube, the possible intervention
of the safety valve may cause flooding. We cannot be held responsible for any damage
caused by neglecting to apply this technical precaution.
The boiler can work only in two following modes:
a) only heating mode
b) heating and sanitary through remote tank
That change are the following aspects:
a) heating mode: two connections 2) and 3) (fig.1) must be plugged with two plugs packed
inside the instructions bag. So you can close two connections to possible remote tank and
the boiler working only with heating circuit. Now must inhibit the sanitary probe (41 fig. 1)
functioning. This carries out on PCB working. See table relatives Dip-Switches positions on
PCB in the chapter 2.6 of this manual. Dip-Switch 6 must be moved to ON; so the
temperature probe is defused and there not will be malfunctioning for the not wanted
sanitary activation.
b) Heating and sanitary mode combined doesn’t occur to do anything because the boiler is
prepared in this mode so by the manufactory. We remember that the sanitary probe 41) fig.
1 must be put on the pocket tank to activate the heating tank. Don’t use the eventual
thermostat tank.
