Radon-T Single Radon T Kit

Product Information: Radon-T System

The Radon-T system is a unique fitting designed for installing or roughing in a radon and moisture system during new construction. It is the important first step in reducing radon levels in new construction (RRNC) systems. The kit includes Radon-T fitting,
Radon-T cap, four stakes, four vent pipe labels, and instructions for installation.

Instructions for Site Preparation and Installation of Radon-T

Prior to Pouring the Slab:

1. Position the Radon-T on a level dirt surface in the location designated for the radon pipe rough-in.
2. Using the supplied stakes, secure the Radon-T to the ground.
3. Glue into the Radon-T a length of 4 Schedule 40 PVC pipe. (Pipe length should allow it to extend a minimum of 6 above finished slab.)
4. Insert the supplied Radon-T cap into the top of the PVC pipe. Do not glue.

After Pouring the Slab:

1. Fill all large openings in the slab. Seal perimeter and all joints in the concrete, cap sump pit openings. Floor drains should be trapped or routed to daylight with non-perforated pipe.
2. Remove the Radon-T cap. Connect and glue PVC riser with appropriate PVC fittings.
3. Route 3 or 4 PVC radon vent pipe through the structure. Pipe routing should be as straight as possible. Try to avoid 90o angles. Avoid traps in the piping so condensation can drain to the soil. In the attic, leave at least 2 ft clearance around the pipe in all directions, with access to the area for future fan installation. Pipe termination must extend at least 12 above the roof surface and at least 10 ft from doors and other openings (including operable skylights) that are less than 2 ft below the termination point.
4. Install a wired electrical outlet (120 volt AC) next to the anticipated radon fan location. Outlet must be within 6′ feet of the pipe riser.
5. Affix one supplied radon label to the pipe at each level of the structure (e.g. basement, first floor, etc.). Be sure the airflow arrows on the labels point away from the slab.

Note: Vent pipe for radon, moisture, and other soil gas removal.
A proper fan must be installed for system to be operational.

Instructions for Radon-T Installation and Site Preparation

(For more detailed descriptions, go toradonaway.com/radon-t)
The Radon-T is the unique fitting specifically designed as the important first step when installing or roughing in a radon and moisture system during new construction.
These instructions provide a quick guide for proper installation. Consult ANSI/AARST CCAH-2013, IRC Appendix F, ASTM E-1465 and your state and local codes to determine appropriate compliance.

Prior to Pouring the Slab
Radon-T Installation

1. In the location designated for the radon pipe rough-in, position the Radon-T on a level dirt surface.
   • For optional 4-way air flow, cut out sides of the Radon-T along the indents.
   • If saddling over an internal perforated pipe loop, cut out a small top section of pipe (approximately 4 ½” x 6”) so that the Radon-T fits snugly over the pipe.
2. Using the supplied stakes, secure the Radon-T to the ground.
3. Glue into the Radon-T a length of 4” Schedule 40 PVC pipe. (Pipe length should allow it to extend a minimum of 6” above finished slab.)
4. Insert the supplied Radon-T cap into the top of the PVC pipe. Do not glue.
5. Save the 4 supplied vent pipe labels for future piping.

Site Preparation

1. Uniformly spread a layer of clean aggregate at least 4” thick. The aggregate should be sized to pass through a 2” sieve but not through a ¼” sieve. (Where gravel is not available, substitute a 4” layer of sand covered by geotextile drainage matting.) See radonaway.com/radon-t for more information.
2. Install vapor barrier (minimum 6 mil or 3 mil cross- laminated) on top of the aggregate. The barrier should cover the entire floor area and seams should have a 12” minimum overlap.

After Pouring the Slab

1. Fill all large openings in the slab. Seal perimeter and all joints in the concrete, cap sump pit openings. Floor drains should be trapped or routed to daylight with non-perforated pipe.

2. Remove the Radon-T cap. Connect and glue PVC riser with appropriate PVC fittings.

3. Route 3” or 4” PVC radon vent pipe through the structure.
   Design reminders :

   • Pipe routing should be as straight as possible.
     Try to avoid 90o angles.

   • Avoid “traps” in the piping so condensation can drain to the soil.

   • In the attic, leave at least 2 ft clearance around the pipe in all directions, with access to the area for future fan installation.

   • Pipe termination must extend at least 12” above the roof surface and at least 10 ft from doors and other openings (including operable skylights) that are less than 2 ft below the termination point.
     

4. Install a wired electrical outlet (120 volt AC) next to the anticipated radon fan location. Outlet must be within 6’ feet of the pipe riser.

5. Affix one supplied radon label to the pipe at each level of the structure (e.g. basement, first floor, etc.). Be sure the airflow arrows on the labels point away from the slab.
