The Enviro Q3 fits the propane to natural gas conversion kit, part number 50-3100, built for units equipped with the SIT Nova (820) millivolt gas valve. It swaps the burner orifice, pilot injector and venturi adjuster so the appliance burns natural gas instead of propane, supporting continued reliable operation over the appliance's service life.

When to replace it

This kit is used when converting an Enviro Q3 from propane to natural gas rather than replacing a worn part. The fuel-specific orifice and injector are marked for the gas type to keep combustion set correctly for the new supply.

Fit

• For Q3L models equipped with the SIT 820 gas valve.
• For the natural gas to propane conversion, choose part 50-3101.
