CNG Conversion
Does anyone have a link where I could find jets to convert a cng stove/oven to propane. CNG is really expensive and being a live aboard you need to cook. My friend bought a kit for 300.00 US but there has to be a better way. Thanks.

Re: CNG conversion
That might depend upon which specific appliance you wish to convert.

Re: CNG conversion
Assuming you can get the proper jet the appliance would be fine, but the real money is connecting up the propane and building a proper propane locker. You'll need a regulator and solenoid shutoff plus other shut off valves. Complete systems from companies like FireBoy do bundle all the propane system equipment. They also add propane sensors that shut off the supply or drive you nuts with a very load alarm. Building the locker so it is not connected in any way to the cabin and has a drain to the outside is usually the part that can get you scratching your head.

The stove is a Regal 2 burner with a one burner oven. For me the hardest part is getting the jets. Propane locker regulator hose and so on would be the easier part. Thanks for the replies. John

Re: CNG conversion
If I may make a suggestion..... find out the jet orifice sizes for Propane and then solder the holes in the old jets... drill to new size and refit.... old gaz conversion trick from the old coal gaz to natural gas conversion in the UK

Re: CNG conversion
contact todd@suremarine.com, I am doing a conversion now. After a lot of searchlng I came across this company. Tell them what stove you are trying to convert and they can set you up with what you need.

Re: CNG conversion
Regarding a propane locker; it's alot cheaper, easier and faster to just mount your tank on the stern rail.

If you do that I would suggest you get one of the Ragasco fiberglass tanks. It has no steel parts. Others are a bit cheaper but they use a steel ring in the valve fitting even though the rest of the tank has no other steel. In short the tank will be worthless in a year from rust just about as fast as a standard steel tank.
If you use premade hoses with standard fittings you can secure the hoses all the way to the units that need them and have a solid install without a locker. There is added security with a locker. An exposed tank could be subjected to all sorts of things that might stress the mounting and have potential disastrous results.

Thanks, Seward products sent me in the right direction. SAFGAS bought regal stoves and the person I talked with was John and they only have a few parts left for regal stoves. The number is 909 910-1090 if anyone has a question regarding regal stoves.
My last boat I put the aluminum tank on the rail with a teak bracket and polished the tank so it would look good on the rail. Thanks all who posted. John

Use your toylet storage tanks at 334 gallons per person. Put a water gas regulater on your out line and run this to your srove as a Methain stove.
keep tank at 70F then you can cook for free for one or two Hrs a day.

Re: CNG Conversion
Hummm if i remember, propane is heavier than air so it will collect in the bottom of your boat if u have a leak.   cng is lighter and if it leaks it will float up up and away and not blow you and your boat to bits
