WARNING: Venting of natural gas to the atmosphere may be prohibited in some areas. Before venting the Compressed Natural Gas (CNG) fuel tank, contact the local gas company to ensure that all local, state and federal regulations are observed.

When venting the Compressed Natural Gas (CNG) system, take the following precautions in order to prevent fire and personal injury:

Use the proper grounding procedure to an earth ground in order to prevent a build-up of static electricity which can lead to an electrical discharge.
Use the CNG Tank Venting Kit (J-42435-A) with a vent stack.
Vent the CNG fuel tank in a well ventilated work area.
Keep sparks, flames, and smoking material away from the area.
Wear the appropriate hearing protection during the venting procedure. A sudden pressure loss from an uncontrolled gas leak can cause hearing damage.
