1Gather the tools and materials
for the installation
C ution: Observe all safety precautions
when you are operating electrical tools
or hand tools.
The following installation instruc-
tions are recommendations for
typical installations. Please refer
to project plans and specs for any
deviation to these instructions.
2Ex avate a tren h for the
hannels
Excavate a trench with a minimum concrete-
surround, by load class:
nClass A: each side 4", depth below 4"
nClass B: each side 4", depth below 4"
nClass C: each side 6", depth below 6"
nClass D: each side 8", depth below 8"
Note: The channel must be recessed 1/8” for
pedestrian traffic and 1/4” for vehicular traffic.
Note: The channel must be surrounded on all
sides by a minimum of 4" of concrete for a Class
A installation. For a complete description of
installation types, see
Lo d Cl ss Inst ll tion on p ge 4.

nHammer
nButyl caulk or adhesive silicone sealant
nCaulking gun
nStringline

nPhillips screwdriver
nConcrete vibrator

nTie wire and self-tapping screws
nPliers and cordless screwdriver

5Assemble the drain outlet
nAssemble the drain outlet with a DS-224 End Cap, drill out
the channel bottom outlet, and install a DS-126 bottom
outlet adapter (if necessary), or
nAssemble an End Outlet DS-227, or
nAssemble a Catch Basin DS-340.
nUse End Cap DS-224 at the shallowest end of the run.
nSet a string line in the trench along each side of where the
channel will be placed, at final elevation of channel. If using
ductile iron frame, place string line 1" below finished grade
to accommodate the frame.
Note: Bottom outlets, drain outlets, and catch
basins connect to the deepest end of the run.
4Lo ate the expansion joints
Plan to install expansion joints parallel and perpendicular to channel
according to plan specification.
Note: ocate perpendicular expansion joints crossing the
channel at the channel joints (if possible).

3Lay the hannels alongside the tren h
nStart the layout at the drain outlet with the deepest (highest
numbered) channel section, proceeding to the shallowest (lowest
numbered) channel section.
nPoint the arrows on each channel section towards the drain outlet.
Note: Channel sections marked with an N are neutral non-
sloped channel sections; for example, DS-090N or DS-100N.

6Assemble the hannels
Note: If using Ductile Iron Frames skip to Step 6A.
The outlet will be at the deepest end. Assemble the channel section
from the deepest to the shallowest.
nRemove the screws from the end of the Blank Grate Insert located
on the male side of the channel (do not remove the center screws
from the insert). Start at the drain outlet.
nPlace a bead of butyl caulking or silicone sealant in the channel’s
joint or groove (if a water tight seal is required).

7Install the rebar for ea h hannel se tion assembled
nInsert rebar into the eveloc rebar support. Drive rebar straight into the ground about 6” to 12” or until rebar
is firmly held in place.
nSet channel to desired grade level and align for straightness using string line.
nContinue attaching pre-assembled channel sections and install rebar until run is complete.
nProceed with final adjustments for grade level and straightness using tie wire or self-tapping screws; secure
rebar to the eve oc rebar support.

6A If using Du tile Iron Frame - assemble the hannels
The outlet will be at the deepest end. Assemble the channel section from the deepest to the shallowest.
nRemove all Blank Grate Inserts from the channel sections.
nPlace a bead of butyl caulking or silicone sealant in the joint or groove (if a water tight seal is required).
nSnap the channel sections together in multiples of two.
nPlace the pre-assembled channel sections in the trench beginning with the outlet end.
nSecure the Ductile Iron Frames to the channel using the DS-123 screws. Install iron grates using DS-225 screws.
nApply a covering or tape to the grates for protection and to prevent concrete from entering the channel.
Qui k Start Guide
nSnap the channel sections together in multiples of two.
noosen the center screws on the Blank Grate Insert; slide the Insert in the
direction of the male end (downstream) so it overhangs or is staggered.
nAlign channel with Blank Grate Insert for straightness. Use self tapping
screws to fasten the Inserts to the channel; ensure the ends are flush with
the edge of the Insert. Cover the slots on the Insert with tape to prevent
concrete from getting into the channel.
nPlace the pre-assembled channel sections in the trench beginning from
the outlet end.
Tip: Cover screw heads in the Blank Grate Insert with tape for easy
removal after the concrete is poured.

9Pour the on rete in the hannel tren h
nPour equal amounts of concrete on each side of
the channel to prevent it from shifting.
nVibrate the concrete to avoid bubbles or voids.
Tip: Installations in asphalt require the
same concrete encasements.
10 Clean up the installation
nAfter the concrete has set for a minimum of 24 hours,
remove the Blank Grate Inserts.
nInstall the grates.
nEnsure that the grates are securely fastened.
Note: Follow the concrete manufacturer’s
recommendations for set-up time and loading.
