I am interested in converting my CNG stove to Propane. Besides changing burners, what other safety concerns are there to think about. Such as vent blowers in the bilge etc..
Please help:confused:

Check like Stu says but I think Steve is probably right on with a jet replacement as that is all they did in my home. In fact, the home water heater came with both natural and propane jets. Chief

Most 'gas' suppliers and gas appliance distributor outlets can do this for you ... and also adjust the burners for the proper air/fuel ratio. Best is to remove the entire stove and take it to them for the conversion and set-up adjustment if youre not completely knowledgeable with CNG/propane regs. as many of the 'regs' have changed over the years:

Just be aware that CNG stoves do not have thermocouple switches so in the event of a flameout propane will continue to spill in the cabin. In so equipped propane stoves in the event that the flame goes out the switch recognizes a change in temperature and will shut the gas off at the burner. Years ago we did not have those safety switches and everyone did fine, it is just a matter of minding the stove while it is lit.
