Corner glass configuration

The WTX 90 Corner features two coupled ceramic-glass panels that provide a wide view of the fire from two directions.

Natural convection and radiant heating

The N19 version operates by natural convection and radiation as standard, without requiring a fan.

Optional forced ventilation

A dedicated Palazzetti radial fan kit can be added when faster hot-air distribution is required.

ET4W smart ventilation control

The optional ET4W control unit allows the ventilation system to be managed via Wi-Fi through the Palazzetti App.

Thermofix® firebox

The combustion chamber uses Thermofix® refractory material, developed for the high temperatures generated by wood combustion.

Sliding corner door

The door uses a robust sliding system designed to provide smooth opening and closing.

Flue-gas bypass valve

When the door is opened, the flue-gas bypass valve helps direct smoke towards the chimney during wood loading.

Primary and secondary air control

Combustion can be managed through separate primary and secondary air regulation.
