MTU Instructions
General Installation and Wiring Guidelines
A long spacer is available, for use when
the lower surface of the pit lid is a flat,
solid surface. A short spacer is used
when the lower surface of the pit lid in
use has a ribbed construction.
Contact Hexagram for information on
approved non-metallic pit-lids.
Indoor Mounting
For an inside mount, mount the MTU
vertically on a ceiling joist. It is important
to mount the MTU as high as possible.
Note: The MTU must be mounted above
grade.
Because the outside wall of a building
can have metal siding or foil insulation,
keep the MTU a few inches away from
the outside wall. Transmissions easily
pass through wood and masonry.
Do not install an MTU inside if the
basement has a metal ceiling or foil-lined
insulation in the ceiling or if it has foil on
the sidewalls running from grade to
ceiling. This will prevent the signal from
transmitting effectively.
Large metal objects such as heating
ducts, steel cabinets or metal ceiling
structures can block MTU transmissions.
Select locations that are at least five to
ten feet away from objects such as these.
Do not mount the MTU if large metal
objects, such as heating ducts, block both
the front and rear of the MTU. If
absolutely necessary, a single large metal
object may be located several feet away
from the MTU.
Unfinished Basement
Step 1 – Select a mounting location for
the MTU that will allow optimum signal
transmission. In unfinished basements,
this is typically high on a ceiling joist, at
least a few inches away from outside
walls.
Step 2 – Mount the MTU.
• The MTU must be mounted
level, vertically with the STAR
logo facing the installer. Allow a
1” space between the top of the
MTU and any overhang above
it. This is critical for proper
radio signal transmission.
• Use a Spacer (Hexagram Part
Number 056-5155H1) if
mounting an Original Flatpak
STAR MTU on a non-wood
surface.
CAUTION!
Do not over tighten screws.
Excessive torque will crack
the MTU enclosure. Do not
tighten screws beyond the
point that the MTU touches
the mounting surface.
