METEO GREEN HE R.S.I.

9 - BOILER INSTALLATION

Boiler must only be installed by qualified personnel.
Boiler is available in the following models:
Model Type
R.S.I. CH only
Meteo Green HE R.S.I. is a C-type condensation wall-mounted boiler and
is able to operate:
- CASE A: only heating. The boiler doesn't supply domestic hot water
Meteo Green HE boilers are fitted with:
- circulation at adjustable speed (PWM = Pulse-Width Modulation)
- 1-10 modulation, the boiler is designed to automatically modulate the flow
rate supplied between a maximum and a minimum (see technical data)
- Range Rated, indicates that the boiler has a device for adapting to the
system's heat requirements, making it possible to adjust the boiler's thermal
load to the energy requirements of the building
The following types of fumes outlet are available for this kind of boiler:
B23P; B53P; C13,C13x; C23; C33,C33x; C43,C43x; C53,C53x; C63,C63x;
C83,C83x, C93,C93x.
In B23P configuration (if installed inside), do not install the apparatus in
rooms used as bedrooms, bathrooms, showers or where there are open
vent stacks without own air exchange. The boiler must be installed in an
adequately ventilated room. See the local and national rules aboutetailed
instructions on installing vent stacks, gas pipes and to ventilate the room.
In C configuration the boiler can be installed in any type of room and there
are no limits to aeration conditions and size of room.
For proper installation, we remind you that:
- the boiler must not be installed over a kitchen or any other cooking equip-
ment
- minimum spaces are to be left in order to allow maintenance operations:
at least 5,0 cm every side and 20 cm under the boiler
- it is forbidden to leave inflammable substances in the room
- suitably insulate heat-sensitive walls (e.g.: in wood).
Support plate and integrated pre-installation template are provided for with
the boiler (Fig. 1.1).
Mounting instructions:
- fix the boiler support plate (F) with the template (C) to the wall and use a
plumb to check that it is perfectly horizontal
- trace out 4 holes (Ø 6 mm) for fixing the boiler support plate (F) and 2
holes (Ø 4 mm) for fixing the pre-installation template (C)
- make sure all the measurements are correct, then drill holes in the wall
using a drill and point with the diameter given previously
- fix the plate to the wall by the supplied anchor screws
- make hydraulic connections.
Fit the lower cover (Fig. 1.2) so that its hooks slip into the relative slots in the
lower part of the boiler. Fix the lower cover with the screws A- B (Fig. 1.3)
contained in the documentation envelope in the boiler.
CLEANING THE SYSTEM AND CHARACTERISTICS OF
HEATING CIRCUIT WATER
After installing a new system or replacing a boiler, clean the heating system.
To ensure the product works correctly, after cleaning, additivating and/or
chemically treating the system (e.g.: anti-freeze, film-formers, etc.), make sure
the characteristics of the water satisfy the parameters indicated in the table.
Parameters Water in heating circuit
PH
Hardness
Appearance
If water hardness exceeds 28°Fr, it is recommended to use water softeners,
to prevent any limestone deposit in boiler due to excessively hard water.
PUMP DUTY
Meteo Green HE boilers are fitted with a variable speed circulation unit that
is already connected up in terms of plumbing and electrics, and the usable
performance it provides is shown in the graph.
The boilers are fitted with an anti-blocking system that starts an operating
cycle every 24 hours when not used, irrespective of the position of the func-
tion selector.
