Palazzetti Ecofire Vivienne TC 9 US: 9.3 kW sealed pellet stove with top coaxial outlet

Palazzetti Ecofire Vivienne TC 9 US is a 9.3 kW sealed pellet stove featuring an elegant circular painted-steel body, Total Black double glazing and a top coaxial flue connection.

The US – Upper Smoke configuration places the flue-gas and combustion-air connection at the top of the appliance, helping reduce rear installation space.

The stove can also be converted into a ductable heating solution by installing the optional Pro2 ducting kit, which adds a rear Ø80 mm hot-air duct.

Standard equipment includes MyDisplay+ with built-in Wi-Fi, Zero Speed Fan, Balanced Door, T3 technology, Complete Burning System, Self Cleaning System, Speedy Clean, Quick Start and the Star pellet-feed system.

US – Upper Smoke top coaxial connection

The US – Upper Smoke configuration provides a top coaxial connection combining flue-gas evacuation and combustion-air intake.

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

Optional Pro2 hot-air ducting

Vivienne TC 9 US can be converted into a ductable stove by installing the optional Palazzetti Pro2 ducting kit.

The kit adds a dedicated ventilation system for a rear Ø80 mm hot-air duct, allowing part of the stove's heat output to be distributed to an additional room.

On the Vivienne range, Pro2 is an optional kit rather than a separate base firebox.

Circular steel design and Total Black glass

Vivienne TC 9 US features an elegant circular painted-steel body.

The outer aesthetic glass is black tempered glass which becomes transparent when the fire is burning, creating a refined Total Black appearance when the stove is switched off.

CC50 sealed combustion: what does it mean?

Vivienne TC 9 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.

MyDisplay+ with built-in Wi-Fi

Vivienne TC 9 US is equipped as standard with MyDisplay+, a graphic display with built-in Wi-Fi connectivity.

The system provides intuitive control of the stove and its daily and weekly operating schedules, together with compatible Palazzetti smart functions.

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 favouring heat distribution through natural convection and radiation.

T3 technology

Vivienne TC 9 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 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.

Performance and pellet consumption

Vivienne TC 9 US delivers a 9.3 kW nominal heat output and can modulate down to approximately 2.8 kW.

Palazzetti technical documentation specifies approximately 91.8% efficiency at nominal output and 90.9% at partial load.

Pellet consumption ranges from approximately 0.64 to 2.11 kg/h. The hopper has a capacity of 18 kg, providing a maximum indicative burn time of approximately 28 hours.

Palazzetti Ecofire Vivienne TC 9 US technical specifications

Installation, coaxial connection and optional ducting
