Fresh Dryer Exhaust System Installation

This was a fire/code compliance project we took on recently in San Mateo, CA. The home purchased a new dryer and upon delivery the dryer would not fit correctly into the existing space. I was not that the dryer was too large but rather the dryer exhaust system was not setup for the space correctly. What was needed in order to correct this situation was the installation of a wall box, which allows more space for the dryer to fit correctly and safely. The main solution that I see in tight spaces is actually a very unsafe once, usually there is a transition duct that looks like a giant slinky, installers use these because they are easy. That said they are 100% incorrect, they are not fore rated and the collapse and tear over time. In order to get our customer up and running we installed the following, A WallBox from InOvate, 12 feet of new 26 Ga hard pipe four inched in diameter a new InOvate DryerWall vent and a UL2158a rate transition duct, which now fits correctly due to the wall box installation.
