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.

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

Ceramic design and Total Black glass

Lilibet TC 12 US 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.

CC50 sealed combustion: what does it mean?

Lilibet 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.

At low and medium output levels, when operating conditions permit, forced ventilation can be completely switched off, allowing heat to be distributed mainly through natural convection and radiation.

T3 technology

Lilibet TC 12 US 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.

Lilibet TC 12 US or Lilibet TC 12 US Pro2?

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

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

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

Performance and pellet consumption

Lilibet TC 12 US delivers a 12 kW nominal heat output and can modulate down to approximately 3.2 kW.

Current Palazzetti product data states approximately 90.9% efficiency at nominal output.

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.
