- This appliance must only be used for the purpose for which it was expressly intended.
- This appliance is intended to heat water to below-boiling temperatures at atmospheric pressure, and must be connected to a
cen-tral heating and/or domestic hot water distribution system, in accordance with its characteristics, performance, and heat
output.
- Before installation, check that the boiler has not been damaged during handling and transport.
- The installation must be performed by duly qualified personnel, in accordance with current standards.
- Before performing any cleaning or maintenance operations, unplug the appliance from the mains power supply.
- THE MANUFACTURER is not liable for any damage to people or things due to errors in installation, adjustment, maintenance, or im-
proper use.
- The boiler and corresponding system must be commissioned by authorized personnel.
- Commissioning is performed in order to verify proper operation of all adjustment and control devices.
- Qualified personnel must be contacted if the appliance is not used for an extended period.
Standards
The installer must observe current local regulations with regard to: the site chosen for the installation of the boiler, compliance with required
ventilation conditions, the tightness of the connection to the chimney, connections to fuel lines, electrical systems, and any other relevant
safety standards.
Warranty conditions
The warranty is only valid if the standards and recommendations for use contained in this manual are observed. Any non-compliance or modifi-cation will

TECHNICAL AND CONSTRUCTIONAL CHARACTERISTICS, DIMENSIONS
4.1 Description of the appliance
The construction of the boilers in the PREXTHERM RSW N series guarantees high power and efficiency with low flue gas temperatures,
thus ensuring low polluting emissions. They are manufactured in accordance with standard EN 303, part 1. The main technical elements
of the design are:
- careful design of geometries to achieve an optimum ratio between combustion volumes and heat exchange surfaces.
- the choice of materials used, to ensure long boiler life.
The boilers feature pressurized combustion with 2 flue passes, a horizontal-cylinder configuration, and flame reversal in the furnace, com-
pletely surrounded by the water that cools it. The flame produced by the burner is reversed peripherally toward the front, where the flue gas
enters the tube bundle, featuring turbulators to create a swirling path that increases the heat exchange by convection. On leaving the tube
bundle, the flue gas enters the rear chamber and is transferred to the chimney.
