Description Technical Specs FAQ / ASK A QUESTION
Metal-Fab Direct Vents utilize a new technology to make their products superior to others. The Special double-wall construction allows direct vent stoves and fireplaces to operate without using air from inside, instead they draw combustion air in from outdoors through the direct vent system. This means that the warm inside air is not being used as fuel, and no fumes, condensation, or smoke will be let into the room.

This high quality Metal-Fab product makes it easy for you adapt your M&G Duravent product to Metal-Fab. This adapter has the same superior quality as the rest of Metal-Fab Direct Vent Products, using the new special double-wall technology.

Why Choose Metal-Fab?

Here are a few key features that put Metal-Fab ahead of it's competitors

Centering brackets are attached to the inner flue, and not the casing. The unique design allows for expansion and contraction while preventing possible misalignment of flue and casing. This removes the need for field assembly of the inner flue and casing.

Their inner flue is heavy gauge 430 stainless steel which fights corrosion and enhances the strength and integrity of the entire vent system.

Precision engineering and construction provide for an airtight connection without the need for a seal that may required by other brands. At the same time this eliminates the need to apply sealant in the field.
