INSTALLATION

5.1 Packaging

- PREXTHERM RSH 100N÷420N boilers are supplied with the door, smoke box, insulation and panels installed.
- PREXTHERM RSH 500N÷950N boilers are supplied with the door, smoke box and insulation installed, and the panels in a separate
cardboard
The ceramic fiber padding for the burner nozzle can be found inside the combustion chamber.

5.2 Handling

5.2.1 For models PREXTHERM RSH 100N÷420N (Fig. 5)
Remove the top panels (1), and use the holes indicated on the front and
back of the boiler (2) in order to lift and move the boiler.
Handle the unit carefully, using suitable equipment for the weight to be
lifted. Before connecting the boiler, remove the wooden base.
5.2.2 For models PREXTHERM RSH 500N÷950N
The boilers are equipped with eye bolts for lifting. Handle the unit carefully,
using suitable equipment for the weight to be lifted. Before connecting the
boiler, remove the wooden base.

5.3 Installation location (Fig. 6)

PREXTHERM RSH N boilers must be installed in rooms to be used exclusively for that purpose, in accordance with current technical stand-
ards and legislation, and featuring adequately sized ventilation openings. The ventilation openings must be permanent, directly open to the
outside, and located in both high and low positions, in accordance with current standards. The location of the ventilation openings and fuel
supply, electrical power distribution and lighting circuits must comply with current legal provisions for the type of fuel used. To facilitate the
cleaning of the flue gas circuit, space must be left at the front of the boiler, greater than or equal to the length of the boiler body, and no less
than 1,300 mm. With the door open 90º, verify that the distance between the door and adjacent wall (X) is at least equal to the length of the
burner. The boiler support surface must be perfectly horizontal. A flat cement base is recommended, able to support the full weight of the
boiler plus the water content. For the base dimensions, see the R x Q distances (dimension table). If the burner is powered by a fuel gas
with a specific weight higher than air, the electrical parts must be located at least 500 mm from the floor. These boilers cannot be installed
outdoors because they are not designed to operate outside, and are not equipped with automatic frost protection systems.
INSTALLATION IN OLD SYSTEMS
If the boiler is to be installed in an old system,
verify that:
- The chimney is suitable for the temper-
ature of the combustion products, has
been calculated and manufactured in
accordance with current standards, and
is airtight, insulated, and not blocked or
choked.
- The electrical system has been installed
by qualified personnel, in accordance with
current standards.
- The fuel supply line and any tanks have
been installed in accordance with current
standards.
- The expansion vessel(s) can completely
absorb the expansion of the fluid con-
tained in the system.
- The flow-rate, static pressure, and direc-
tion of flow of the circulation pumps are
suitable.
- The system is clean, free of slime and de-
posits, vented and watertight.
- A treatment system is available for supply/
top-up water (see reference values).
