360 Siphon Fume Extractor - Engineered Aerodynamic Vent Cap
Surface Mount for sealed roof top installations

The 360 Siphon is designed very much the opposite of the conventional vent cap.  Its patented design invites the wind from all directions and angles, channeling as much air as possible to its center.

Any wind will create a low pressure, pulling out fumes.  The design of the unit makes it physically impossible for high pressure or wind to enter the stack.  Even when an RV is stationary, a slight wind will enable the 360 Siphon Fume Extractor to pull fumes from any holding tank.

The “360 Siphon” installs on the RV roof top the same as all the conventional vents.
Includes a water sealant collar to insure no water travels between the stack and roof.

If you are uncomfortable with working with the roof membrane and water sealants, please see your local RV service center.

1. Remove old vent base, careful not to damage roof membrane. Clean area of old caulking and dirt. Fill old mounting holes.
2. Remove sealant collar and calking (calking is included on the low profile packaged Siphon) from the "360 Siphon", unravel caulking , and attach around the bottom side of the flange, reinstall collar and place over vent stack.  Align collar to fit inside of vent stack.  
3. If the base flange does not come in contact with the roof, the vent stack is too high and must be shortened (use a hack saw). Reinstall "360 Siphon" to insure collar fits into stack, if stack is too short, pull collar part way out from the base.
4. Do not remove top section of cap
5. Secure flange to roof using exterior screws, ensure screw length is correct for your roof type.
