Securing the Unit
The TB17 is designed to be secured in the aircraft using hold-down tie rods. The hold-down
bar, TBP P/N 9017867 can be attached to the TB17 using tie down rods. The hold-down
bar contains two holes, 0.310 inches (7.9 mm) in diameter, located 7.9 inches (200.7 mm)
apart. Tie-down rods are inserted through the holes and tightened to approximately 20 in-
lbs (2.5 Nm).

Vent Installation
It is recommended that the TB17 be operated with the vent tube in place when installed in
the aircraft. The vent is located on the top of the unit, has a diameter of 1.0 inch (25.4 mm)
and is 0.75 inches (19 mm) tall. Use the vent tube and attachment hardware as supplied in
the Vent Kit, P/N 9018049. Contact True Blue Power for potential alternatives. The vent
tube should be properly and securely attached to an aircraft exit point which would allow
any gaseous emissions to be vented overboard. The TB17 produces no emissions during
normal operation. Emissions will only be present in the event of a battery failure. Be sure to
locate the vent where emitted gases would not be directed toward any of the aircraft’s air
intake ports.
