Convert Zeno CNG Stove to Propane

Hello all:

I have an Eno CNG stove.

What do I need to do in order to convert that to propane?

The basic first step is to talk to ENO. Normally it just requires a different orifice in the burners. ENO can give you the part number, and anything else that may be required.

Re: Convert Zeno CNG Stove to Propane

I can't speak specifically about your stove, but generally, the CNG "jets" have larger holes than in a propane stove. One needs to figure out how to make them smaller (solder and re-drill) or buy replacements that are drilled for propane.

The CNG stoves also didn't come with thermocouples, which is a safety switch found on the new propane stoves that cuts off the flow if the flame goes out. A thermocouple is not required for operation, but forgoing it increases risk. One could simply not leave the stove un attended and regularly check that the flame is lit if using the oven, but it still isn't perfect.

I'm trying to go down this road, but it isn't easy to find the parts. The make of my stove stopped supplying the conversion parts a few years ago. That said, when the alternative is spending $1,500 on a new stove (versus $100 for the conversion parts), I'll keep trying!

Beyond this, you'll need rest of the propane set up with a properly vented tank, regulator and hose to spec, shut off valves, propane sniffers, etc.

Maybe talk with a propane supplier. They know that stuff. Most home stoves are supplied for natural gas from the manufacturer, but many are converted to propane. I thought the orifice went in a line connection?..not the burners...? I don't really know though. I bought a new stove and the installer converted it, I forget what he did though.

Re: Convert Zeno CNG Stove to Propane

Ones I have messed with have a little jet right at the burner itself, looks like a carb jet, even screwed in like a carb jet. I think you would have to have one per burner to properly meter the gas.
But if it doesn't have the thermocouples, I would not do the conversion myself
