CC50 sealed combustion: what does it mean?

Theo TC 6 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 and Silent operation

The variable-speed room-air fan features Zero Speed Fan.

At low and medium output levels, when operating conditions allow, forced ventilation can be completely switched off. Heat is then distributed mainly through natural convection and radiation for quieter operation.

T3 technology

Theo TC 6 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.

This helps reduce routine manual cleaning and maintain more consistent operating conditions.

Complete Burning System

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

Speedy Clean

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

Quick Start

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

Optional Pro2 hot-air ducting

Theo TC 6 can be equipped with the optional Pro2 ducting kit, allowing warm air to be distributed to another room through an Ø80 mm duct.

Universal Gateway

Theo TC 6 is compatible with the optional Universal Gateway, allowing integration with compatible connected functions within the Palazzetti ecosystem.

Performance, consumption and burn time

Theo TC 6 delivers 6 kW nominal heat output and can modulate down to approximately 2.5 kW.

Efficiency reaches approximately 90.5% at nominal output and 91% at partial load.

Pellet consumption ranges from approximately 0.57 to 1.38 kg/h. The hopper has a capacity of 22 kg, providing a maximum indicative burn time of up to approximately 39 hours.

Palazzetti Ecofire Theo TC 6 technical specifications

Installation and chimney system
