Fuel Conversion - Lennox Elite Series Installation And Operation Manual

Fuel Conversion

Converting the stove between natural gas (NG) and propane (LP) can be
accomplished by either changing the cassette (valve and pilot assembly)
or installing a conversion kit (regulator, burner orifice and repositioning
the slide orifice of the pilot). Only a qualified service technician should
perform the conversion.
Conversion Kit
Please see instructions provided with conversion kit.
