INSTALLATION

5.1 Packaging

The PREXTHERM RSW model 1250N-1890N boilers are supplied complete with the door and smokebox fitted and insulation on the body, while
the casing is contained in a separate cardboard box. The instrument panel is supplied in a cardboard box and positioned inside the combustion
chamber. The RSW model 2360N-6000N boilers are supplied complete with insulation and casing. The instrument panel is supplied in a card-
board box and positioned inside the combustion chamber.

5.2 Handling

The PREXTHERM RSW N boilers are fitted with eyebolts for lifting.
Make sure the hoisting equipment used is suitable for the weight being lifted.
Before positioning the boiler, remove the wooden base support
by unscrewing the fastening screws (Fig. 6).
5.3 Local de instalación (Fig. 7)
PREXTHERM RSW N boilers must be installed in rooms to be used exclusively for that purpose, in accordance with current technical standards
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, electri-
cal 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
Cuando se coloque la caldera en instalaciones antiguas, verifique que:
If the boiler is to be installed in an old system, verify that:
- The chimney is suitable for the temperature 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 contained in the system.
- The flow-rate, static pressure, and direction of flow of the circulation pumps are suitable.
- The system is clean, free of slime and deposits, vented and watertight.
- A treatment system is available for supply/top-up water (see reference values).
