the universal infinity drain provides design-centric decorative options with an
innovative installation method that is compatible with every type of waterproofing the channel is
available in pvc and abs the complete kit includes one channel two clamping collars number 1032
clamping screws and four quarter inch 20 leveling screws locate the intended position for the
linear drain by measuring the desired space and marking the center location for the drain outlet
make a hole at the marked location for the drain outlet using a three and a half inch hole saw this
drain can be connected to a two inch or three inch nominal pipe lay water resistant paper
over the subfloor staple into place and make a cutout for the outlet hole then lay wire lath
staple into place and make a cutout for the outlet hole in preparation for the primary mortar bed
place the drain channel into position and ensure it is level using the leveling screws under the
channel turn each leveling screw counterclockwise to raise the drain and clockwise to lower ensure
the drain is parallel to the wall then connect the waste line to the outlet of the drain channel
using the appropriate primer and glue spread a layer of dry pack mortar around the drain and
up to the flange of the linear drain channel ensuring all areas under and around the channel
are backfilled then spread mortar across the intended shower area while keeping a consistent
pitch towards the drain channel consult your local code for the appropriate degree of pitch
allow the mortar bed to dry overnight if not already removed remove the stainless steel
clamping collar by unscrewing each screw and set aside apply an appropriate adhesive across
the mortar bed and drain channel and lay the waterproofing membrane over this adhesive ensure
each corner is folded in each corner without cuts the membrane must extend at least four to
six inches above the floor and stapled at that height consult your local code for exact heights
using a utility knife cut a slit over the middle of the opening of the linear drain then carefully
pierce the waterproofing membrane at each screw hole of the drain channel and cut out a 3 16 inch
diameter hole for each screw screw on the clamping collar to the linear drain channel with the hem
edge facing up using the number 1032 screws using a screwdriver do not over tighten note that there
are two clamping collars provided in each kit one half inch in height and one inch in height
confirm the finished tile thinset and secondary mortar bed thickness before choosing in most
cases the one inch high clamping collar will work for a traditional waterproofing installation cut
out the waterproofing membrane that is over the inside of the drain channel using a utility knife
install backer board directly to the framing and over the waterproofing membrane that runs up the
wall be sure not to place any screws below the line at which the waterproofing membrane
ends mark the thickness of the finishing material plus thinset from the top of the clamping collar
along the outside of the collar this will serve as a guide for the second layer of mortar
spread pea gravel around the weep holes of the collar to prevent blockage
then spread a layer of dry pack mortar up to the mark made on the clamping collar and
across the intended shower area while keeping a consistent pitch towards the drain channel
consult your local code for the appropriate degree of pitch allow the mortar bed to dry overnight
ensure that the tile height will be accommodated with the clamping collar used then apply thinset
mortar to the floor using the appropriate trowel then lay floor tile after the floor tile is dry
apply thinset mortar to the vertical walls and set the wall tile into thinset
once dry grout all tile joints place the decorative grate or tile insert into the
channel and adjust the leveling feet so the grate sits flush with the finished floor
