Design the right version

The model name is only the beginning.

Connection, height, oven direction, surface and added mass can change the price, appearance and way the heater belongs in the floor plan. These are the decisions worth resolving before a formal quote.

01

Fire view

Panorama and corner-door configurations make the flame visible from more than one direction and can help the heater address a larger room.

02

Placement + connection

The corner geometry, floor protection, clearance and chimney connection must be coordinated together; selected families offer both base- and top-vent versions.

03

Height + thermal mass

An additional heat-storage course is available for many families when structure, heating needs and proportion support it.
