Installation of Tile Flange on Adjustable or Flat Shower Pan
It is important to follow the directions herein, not to do so will cause problems in the future. There are hundreds of adjustable shower pan molds on the market and each manufacturer figures out the best method to install a tile flange to pass the local codes. American Acrylic & Injection, Inc. has now manufactured a PVC flange that is applicable to current UPC codes if installed as directed.
1. After you have manufactured the marble pan remove pan from the mold and turn it upside down and set it on a 55 gallon drum or some structure that will hold it off the floor.
2. Clean the outer top edge of the pan to remove all dust and dirt.
3. Using solid surface American Bond adhesive, spread approximately 1/8" of adhesive around the entire outer pan about 1/4" from the edge. This adhesive will give greater than 500 PSI pull between shower pan and tile flange which ANSI Z124 calls for on two items adhering to each other.
4. Since you have already pre-cut your tile flange to exact size, you now install the flange around the outer edge as shown in drawings. Allow to set at least 4 hours. If the tile flange is not exactly straight, you may find it necessary to put approximately 3 spots of hot glue on edge of marble pan to hold tile flange in place until adhesive sets.
5. After the adhesive has set and will hold in place, you must now cut the corner PVC strips and glue them to each of the four corners with any approved PVC glue.
6. Now that the adhesive is set and all corners have been installed, you may now turn the pan and tile flange.
7. Using a high grade sillicone, you should now fill the slot between shower pan and tile flange.
8. After the slot has been filled with silicone, you should now press part #B of the shower pan flange into part #A which is the large portion of the tile flange.
9. You should now fill in above the small portion "part B" of the tile flange with silicone to assure that no leaks will occur.
10. The shower pan is now ready to install and if installed properly should never leak.
It is important to follow the instructions exactly to assure your customer and city inspectors that leaks will not occur in the years to come. Remember that you must take responsibility for your work, so take NO SHORT-CUTS.
The above shower pan and tile flange as described above has been tested by an approved IAPMO laboratory and can meet the UPC codes, however you should check with your local code enforcement agency to assure acceptance. Laboratory test results should be included when contacting your local code enforcement agency.
