Air Pro System 2

The Air Pro System 2 configuration uses two independent fans.

One fan heats the main installation room, while the second fan 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 connection.

The system uses an Ø80/130 mm configuration, with the inner Ø80 mm duct used for flue gases and the outer section used for combustion air.

CC50 sealed combustion: what does it mean?

Lilibet 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.

Ceramic design and Total Black glass

Lilibet TC 12 US Pro2 features elegant ceramic cladding and a rounded body.

The external aesthetic glass panel is made from black tempered glass and becomes transparent when the fire is burning.

Zero Speed Fan

The main-room fan features Zero Speed Fan, allowing forced ventilation to be completely switched off when operating conditions permit.

T3 technology

Lilibet 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 minimise 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

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

Current Palazzetti technical documentation specifies approximately 90% 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.

Palazzetti Ecofire Lilibet TC 12 US Pro2 technical specifications

Installation, coaxial connection and ducting

Lilibet TC 12 US Pro2 is designed for an Ø80/130 mm top coaxial connection, combining flue-gas evacuation and combustion-air intake.

The Air Pro System 2 rear hot-air duct uses an Ø80 mm connection and can reach up to approximately 14 linear metres, depending on 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 Lilibet 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 incentives for qualifying biomass heating installations. Eligibility for Conto Termico 3.0 depends on the type of project, the appliance being replaced and compliance with all applicable technical and administrative requirements.
