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 configuration 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 combines a steel structure with ceramic cladding, providing a balance between structural strength and refined styling.

The double-door arrangement separates the aesthetic outer panel from the technical combustion-chamber door.

CC50 sealed combustion: what does it mean?

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

Balanced Door

The Balanced Door system uses a self-balancing mechanism designed to help maintain correct combustion-chamber closure during temperature changes.

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 latest-generation 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.

Nadine TC 12 US or Nadine TC 12 US Pro2?

The Nadine TC 12 US described on this page is the standard ventilated configuration with a top coaxial outlet.

Customers requiring warm-air distribution to an additional room should choose the specific Nadine TC 12 US Pro2 configuration.

The Pro2 version uses two independent fans: one for the main installation room and one for the rear Ø80 mm hot-air duct.

Performance and pellet consumption

Nadine TC 12 US 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 and chimney system

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

The US configuration combines the flue-gas and combustion-air connections at the top of the stove, helping reduce rear installation space.

The chimney system and coaxial adapters 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 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.
