Converting the E33's Nova millivolt log burner from propane to natural gas means changing the burner orifice, pilot orifice, and valve setting so the unit burns correctly on the new fuel supply. The Enviro E33 Log Burner Conversion Kit, part 50-2518, is the genuine propane-to-natural-gas kit for the Enviro E33 log burner with the SIT Nova valve. It supplies the parts needed to switch the burner and valve over, with the unit's gas valve flipped so the red o-ring no longer shows once set for natural gas.

Fit

• For E33 Nova log models — the Enviro E33 gas insert fitted with the Nova gas valve.
• For the reverse conversion, natural gas to propane, choose 50-2514.

When to replace it

This kit is needed when an E33 running on propane is being switched to a natural gas supply, since the unit ships from the factory set for natural gas and requires the correct orifice and valve setting for proper combustion on the fuel actually being supplied.

What's in the kit

• 1 natural gas burner orifice, #36 DMS
• 1 pilot orifice
• 1 conversion label
• 1 installation instruction sheet

Installation

This kit should be installed by a licensed gas technician in accordance with local codes.
