BEFORE YOU BEGIN
Always consult with the local building code official prior to installing the system to ensure you are meeting all code and safety requirements. Trex is not responsible for improper or non-recommended installations.
Scan this QR code to view a video on design and layout considerations to keep in mind when installing the Trex RainEscape system.
DO'S Make all joists straight and square. Add outlets to gutter every 12' - 14'. Cover all joists and blocking with trough material, then butyl tape.
DON'TS Do not staple Trex RainEscape products anywhere other than into or over floor joists, ledger, rim joists, or headers. Do not use spiked hidden fasteners, or any fastener without a flat base to provide pressure to butyl tape. Call a Trex RainEscape Specialist at 1-877-348-1385 for recommendations. Do not over drive double thread screws. Do not stand anywhere other than the top of the floor joists, ledger, rim joists, or headers. The Trex RainEscape system can not support body weight. Do not use nails to attach the deck boards above the Trex RainEscape system.
Cover the Trex RainEscape system with deck boards. Ensure the troughs and
downspouts are dry and clear of debris before applying tape. Acclimate the trough before installing. Install the trough material with the shiny side up. Only use Trex RainEscape branded products.
HELPFUL TIPS
THE TREX RAINESCAPE SYSTEM IS MORE EASILY INSTALLED WITH TWO PEOPLE WORKING TOGETHER SNOW BUILD-UP Snow will sit on decking until it melts and then it will run through the system. LEAVES If leaves and debris accumulate in the troughs, a standard washing or a hard rain will clean out the system . IF THE TAPE WILL NOT STICK In areas, such as the perimeter, brick or stucco, where the Trex RainEscape tape will not stick, use the Trex RainEscape butyl caulk to adhere the material.
CAUTION Do not splice trough material. If the trough material is spliced it must be replaced.

3. THREE TYPES OF FLASHING:
No Flashing with Brick or Stucco » If installing against brick or stucco and you DO NOT need a 100% water tight seal, use the caulking method. (3C) Trex does not endorse installing the system without flashing. If installation with flashing is not possible, refer to your local building code official for an exception.
With Flashing » When using flashing add a bead of butyl caulk at the ledger board and between the flashing and trough. Tape over the flashing to the top of the trough using the 4" RainEscape butyl tape. (3A)

4. INSTALLING THE TREX RAINESCAPE TROUGHS NOTE: If installing when temperatures fluctuate drastically, be sure to acclimate trough material before installing. Especially if you are using black. Here are two ways. » Fold a soft crease down the center of the trough. Be sure to account for the offset if installing for a 12" joist bay. (4A) » Unroll trough material, giving plastic time to relax and acclimate to outdoor temperatures.

9. INSTALLING TREX RAINESCAPE SOFFIT LIGHTS
PLANNING NOTE: When designing your deck, plan locations of lights, power supply, timer, and dimmer. These should be accessible for service. Installing a GFCI outlet is REQUIRED to help prevent damage to lighting from electrical surges. (9A)

1. The dimmer remote will work in a 30' (9.1 m) radius of the unit. 2. Dimmer should be installed in a dry location. 3. Timer must be installed vertically with receptacle facing downwards. Timer must be at least 1' (.30 m) from ground level when installed as per federal safety code height regulations. Timer must be in view of the sun to use the dusk/dawn feature. NOTE: For installations where the transformer is hardwired to an AC switch, please consult a licensed electrician. INSTALLING WIRING NOTE: It is recommended to install wiring and splitters before decking and railing is installed. »Use male-to-male connection wire (lengths vary) that will connect to each required splitter. 1. Wiring must be run through deck joist at desired location. DO NOT run wires between deck boards and joists. Staple to frame with cable staples at least 1/4" (0.6 cm) wide. DO NOT crush wire insulation with staple.

GENERAL INFORMATION » ALWAYS consult local codes before beginning a project. » USE TREX TRANSFORMER ONLY. Use of any other transformer voids warranty.
»Lights must be installed in a dry area. »Allow light to cool before removing.
»T he light requires an unobstructed cooling zone around and above the light. Under no circumstance is this 2" zone to be reduced either through insulation or construction materials.
MEASURING 1. Measure joist length and divide by 5. 2. Measure deck width and divide by 5.

MAKING CONNECTIONS 1. Install splitters to inside of framing using hardware provided. Install a splitter at every junction where you will run a row of lights. (9E) 2. Run wire through joist and roll up 1' - 2' (0.30 m - 0.60 m) extra wire in area the light will be installed. Staple to the side of the joist (making sure not to staple through the wire). 3. Cap off all unused female connections on splitters using caps provided or weather resistant silicone. (9G)

Cut the downspout following the line. (Some downspouts may have this line pre-indicated). » Staple the trough material from the end of the cantilever over the existing trough. Repeat all the steps as necessary for trough installation. » Tape over all joists and seams.
» When using surface mount post, pre-drill holes then use a small amount of butyl caulk on screw threads to seal holes. » DO NOT use too much butyl caulk or it will overflow on deck and post mount.
NOTE: Please refer to Trex.com for detailed post mount instructions.

FREQUENTLY ASKED QUESTIONS
Q: Do you have installation videos? A: Yes, visit trexrainescape.com for installation videos and photos.
Q: Can I install the system myself? A: Yes, however, it is easier to install with two people. If you have any questions, call a Trex RainEscape specialists at 1-877-348-1385.
Q: Can I install this over an existing deck? A: Yes, however, it is ideally installed during new construction. You will need to remove the existing deck boards to install the system.
Q: How durable is the Trex RainEscape System? A: Trex RainEscape is made with durable poly and ultra violet inhibitors. This will protect the Trex RainEscape system from sun, snow and rain. The system comes with a 20-year warranty. Q: How do you clean out the debris? A: There should be very little, if any, debris that enters the system because it has to be small enough to fit through the decking. Regular deck maintenance prevents most debris build-up as small debris simply passes through the system with water. In the rare case that there is some build up, use the 2x4 access panel. Q: Can I install the Trex RainEscape system near Low-E doors and windows? A: Yes, but caution must be used. Low-E glass reflects more sunlight, and it can be observed that the extra reflectivity combined with any concavity in the glass can act like a concave mirror, concentrating sunlight onto outdoor objects including decking. This can result in an extreme amount of heat in areas of the decking surface which can cause more movement of the deck than usual. Care should be used in choosing fasteners so as not to cause issues with the RainEscape system.
Q: How bright is the Trex RainEscape Soffit light? A: The output of the Trex RainEscape Soffit light is about 500lm which is roughly equivalent to a 45W floodlight in the same color temperature.
Q: If I run into problems, is there a number I can call to ask questions? A: Yes, please call a Trex RainEscape specialist at 1-877-348-1385 or visit www.trexrainescape.com.
