Air Pro System 2

The Air Pro System 2 configuration uses two independent fans.

One fan heats the main installation room, while the second is dedicated to the rear Ø80 mm hot-air duct.

Palazzetti specifies up to approximately 14 linear metres of ducting. The actual achievable length depends on bends, terminals, pressure losses and the characteristics of the building.

US – Upper Smoke top coaxial connection

The US – Upper Smoke configuration provides a top connection for the chimney system.

The coaxial arrangement combines flue-gas evacuation and combustion-air intake within the same installation system.

This helps reduce rear installation space and can provide a cleaner integration of the stove into the room.

Ceramic cladding and double-door design

Nadine TC 12 US Pro2 combines a steel structure with ceramic cladding and a double-door arrangement with separate aesthetic and technical doors.

CC50 sealed combustion: what does it mean?

Nadine TC 12 US Pro2 is a CC50 certified sealed pellet stove.

CC50 means that combustion-chamber airtightness is verified at a pressure difference of up to 50 Pa according to EN 16510.

Combustion air can therefore be supplied directly from outdoors rather than being taken from the installation room.

This is particularly relevant in modern well-insulated buildings, low-energy homes and properties with controlled mechanical ventilation. Installation compatibility must always be assessed by a qualified installer.

Zero Speed Fan

The main-room fan features Zero Speed Fan.

When operating conditions permit, forced ventilation can be completely switched off, improving acoustic comfort and allowing heat to be distributed mainly through natural convection and radiation.

T3 technology

Nadine TC 12 US Pro2 uses Palazzetti's T3 technology, based on four enlarged flue-gas tubes designed for efficient heat exchange and simplified cleaning.

Self Cleaning System

The Self Cleaning System automatically cleans the pellet burn pot by periodically discharging combustion residues.

Complete Burning System

The Complete Burning System promotes more complete pellet combustion and helps reduce residual ash production.

Speedy Clean and Quick Start

The Speedy Clean system provides front access to the flue-gas circuit, simplifying routine cleaning and maintenance.

Quick Start is designed to reduce ignition time and allow the stove to reach normal operating conditions more quickly.

Performance and pellet consumption

Nadine TC 12 US Pro2 delivers a 12 kW nominal heat output and can modulate down to approximately 2.8 kW.

Palazzetti technical documentation specifies approximately 90.9% efficiency at both nominal and partial load.

Pellet consumption ranges from approximately 0.64 to 2.75 kg/h. The hopper has a capacity of 15 kg, providing a maximum indicative burn time of approximately 23 hours.

Installation, coaxial connection and ducting

Nadine TC 12 US Pro2 uses an Ø80 mm flue outlet with a top coaxial connection.

The Air Pro System 2 rear duct uses an Ø80 mm connection and can reach up to approximately 14 linear metres, depending on the installation layout.

The chimney and ducting system must be correctly designed and installed by qualified personnel in accordance with current regulations and Palazzetti's technical instructions.

A+ energy class, 5-star rating and incentives

Palazzetti Ecofire Nadine TC 12 US Pro2 is rated A+ for energy efficiency and achieves the Italian 5-star environmental rating under D.M. 186.

Palazzetti documentation refers to Conto Termico 3.0 and applicable tax incentives for qualifying biomass heating installations. Eligibility depends on the type of project, the appliance being replaced and compliance with all applicable technical and administrative requirements.
