Preparation
Installation
The substrate must be clean, even, and load bearing. Any leveling must be
done prior to shower tray installation. Locate and cut a hole in the substrate
for the drain outlet and coupling to the waste pipe using the template provided
[3-1/2" (88.9 mm)]. Limit the diameter of the hole to 4" (101.6 mm) maximum
to ensure proper support for the tile assembly. When KERDI-LINE-VARIO is
installed against the wall, locate the drain outlet hole 1-3/4" (44.45 mm) o.c.
from the face of the wall board. Note: Fill in box-out in concrete floors with
dry-pack mortar or concrete. A pipe coupling or similar can be used as a form
around the waste pipe.
• Template note:
The full sheet includes two perforated templates to be removed and used
for installation. One template for outlet/subfloor cutout and one template
for the KERDI-LINE-VARIO flange support.
