Nova Sit 820 Gas Valve for all Enviro Gas Stove Models.

This replaces older part #EC-006 and all other Nova Sit Valve Part Numbers from Enviro.

This valve is used for Natural Gas or Propane (lpg) and comes with adjustable Universal Regulator that can be changed from Natural gas to Lp/Propane by removing the allen set screw and flipping the inner orifice over and reinstalling it.

The fuel is changed by removing a black plastic cover from the top of the low/high heat adjustment dial. If the O-Ring/washer under the black plastic adjustment cap is showing then it has been converted to LP/Propane.

If the O-Ring/washer on orifice under the set screw not showing it is ready for use with Natural gas.

This is the way these valves come from the factory. Old Part # SC-820-844 New Part #20012218
