MTU Instruction
for DFW Rectangular Composite Pit Lids
Installation Procedure
Mounting a New Flatpak STAR MTU to
a rectangular DFW composite pit lid.
Step 1 – Place the lid top down and use a
template to mark and drill two pilot holes
in the bottom surface of the pit lid as
shown below.
Note: A paper template is included in this
document. The spacing between the two
holes must be 6.81” (6 13/16”).
The pilot holes should be along the solid
ridge running across the pit lid as shown,
positioned away from the finger hole.
Step 2 - Place plastic spacers under the
mounting tabs on the MTU as shown
below, and attach the MTU to the pit lid
with the 2 ½” stainless sheet metal
screws. Insert the screws through the
mounting holes and spacers and into the
pre-drilled pilot holes.
Be sure to use the long spacers
(Hexagram Part Number 056-8150L).
You will note that one end of the spacers
has a semi-circular ridge that mates with
the mounting tabs on the MTU.
