120 v gas oven on 40A breaker

At one of my properties, I found out & verified per the owners manual that the gas oven operates on a 120V plug. (Even though I can't see the plug behind the cabinet insertion.) Thing is it's also on a 40A breaker which is concerning me.

I checked the panel, removed the tie on the breaker and determined only the top breaker toggle is supplying the oven. So I'm thinking I need to get a 15A breaker in that slot after I remove the 40A.

The kicker is that the 40A to the oven has Aluminum #6 or #8 wire on it--too thick for a 15A breaker. So my questions:

Can I splice the aluminum down to a #14 wire for the 15A breaker? What is the best, safest way to do that,?, --knowing there are rules about aluminum connected to copper? If not what are my options? Thanks!

You can use Cu/Al split bolt, tape with rubber splicing tape and tape again with regular electric tape.

Or
Cu/Al splice connector, tape with rubber splicing tape and tape again with regular electric tape, or just heat shrink.

Or

You can use a polaris connector (most expensive and harder to find)

You should also check how it is connected behind the oven.
Al wire that large will not fit on 120V outlet either and the proper way would be to use above methods to convert wires to smaller gauge wires (14 AWG in this case), then connected to the outlet.

It cannot be hardwired. If it is needs to be fixed.

And do I need to use a certain liquid to coat the connections?

Not necessary with correct connectors, but not a bad idea to apply some to prevent corrosion. You can buy a small tube of Noalox and coat exposed aluminum wire with it.
