M113A3 FOV: Inspect Personnel Heater Exhaust

 
Crewmen,

The last thing you want during cold weather operations is a leak in your M113A3’s personnel heater exhaust piping.
        
Exhaust leaking into the crew compartment can cause serious injury or even death. If you smell, or just think you smell, exhaust fumes in the crew compartment, open the hatches immediately and evacuate if possible. Then contact maintenance for repairs.
        
Leaks happen when the exhaust piping isn’t fastened together properly or is obstructed.  Operators, just like it says in the -10 TM, be sure to inspect your vehicle’s personnel heater exhaust and check for leakage.

Pay special attention to the air intake elbow and the heater exhaust elbow to make sure they’re not blocked by debris and that the exhaust piping is properly fastened.
         
Mechanics, make sure you also inspect for leaks like the -20 TM says whenever you replace a heater. Pay special attention to the air intake elbow and the heater exhaust elbow to make sure they’re not blocked by debris and that the exhaust piping is properly fastened.
 
Make sure that the exhaust piping is properly fastened.
