The Enviro E25 conversion kit (part 50-3982) fits the Enviro E25 gas insert and converts it from propane to natural gas on units equipped with the SIT Nova valve. It supplies the correct orifices and labels needed to switch fuel types so the burner and pilot operate properly on natural gas.

Fit

• Fits the Enviro E25 with the SIT Nova valve (SIT 885 IPI or SIT 820 Standing Pilot).
• For the natural gas to propane direction, choose 50-3981.
• IPI units also need the IPI stepper motor, ordered separately as 50-3870.

When to replace it

Use this kit when switching the E25 insert's fuel supply from propane to natural gas, so the orifices and valve setting match the new gas type for proper combustion and pilot operation.

What's in the kit

• #38 bullet orifice
• Natural gas pilot orifice
• Rating plate conversion label

Installation

This kit should be installed by a licensed gas technician, with the gas supply shut off before electrical power is disconnected, in accordance with local codes.
