2-Sided Built-in Opti-Myst Fire Inserts
A 2-sided Opti-Myst fireplace, also called a tunnel fireplace, is a built-in Opti-Myst fireplace with two open sides, allowing the flames of the fire to be seen from two opposite sides of a wall, for example between the living room and kitchen.
A tunnel water vapour fire requires no chimney or flue, so it is easy to install the fireplace yourself. There is no need for certifications or professionals to approve the installation.
However, an Opti-Myst fire must be connected to electricity and therefore requires access to power or an electrical outlet near the installation.
