Radon Installation
IMPORTANT: All installations in Radon environments should be done by a qualified professional and in accordance with
applicable codes.
A. The access cover must seat against the secure cover to ensure the gaskets provide a sealed gas-tight system (see fig. 5).
Additionally, ensure that the gaskets between the covers create a seal.
B. Install a 3” vent line at the cover connection labeled “OPTIONAL RADON VENT LOCATION”. Use a 4” hole saw to create a hole
in this location. A dimple is provided on the cover to properly center the drill (see figure 4, above). Install the provided 3” pipe seal
in the hole. Place 3” PVC vent pipe from the vent system through the pipe seal. Do not place the vent pipe more than 4” into the
basin.
