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.
