- 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-

4. TECHNICAL AND CONSTRUCTIONAL CHARACTERISTICS, DIMENSIONS
4.1 Description of the appliance
The construction of the boilers in the PREXTHERM RSH 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.
The boilers are fitted with a door featuring hinges that can be reversed for opening to the right or left, and is adjustable in both height and
depth. The body is insulated with a thick layer of glass wool, and covered with a further layer of tearproof material. The external finish con-
sists of painted steel panels.
