Lucky : I'd check with your local gas company or maker of your stove for that answer. 
They should be able to tell you if the burners that are on your CNG stove are the same or should be changed to burn methane gas!!
It's serious business to make sure that the burners are compatable with the gas fuel that you're using - very serious!!!!!   :think

CNG is primarily methane - see:  http://en.wikipedia.org/wiki/Natural_gas.

But you sill might want to check with the stove manufacturer.   

That would be handy if you can get CNG tanks filled at welding supply companies.

I just read further down the article to where it says:

it must undergo extensive processing to remove almost all materials other than methane.

That says to me that CNG is methane and you should be OK using it in your stove.   :thumb:

Call Seaward 3721 Capitol Ave, Whittier, CA 90601-1732 (562)-699-7997, Dennis Xtn 210

Ask Dennis for the name of the gentleman there who si the specialist on stoves.

First look inside the cover of your stove to find the serial #, you'll need it to discuss the issues with Seaward.

To find this, just take the burner covers off and raise the lid.

Al,

I too have been trying to figure out what I want to do about my 1987 that has CNG.  I've called a number of places, and the net result is it would be very costly to stay with CNG from a shipping and product access basis.  However, I am reluctant to convert to propane if I can avoid the cost, and the concern I have of handling propane.  I like the idea of CNG being lighter than air, so it disapates into the air making it safer to use.

If you get any clear info from your contact about using methane, would you please post it? 

Thanks!

Yes, propane is heavier than air and CNG is lighter than air.  But both are cooking fuels and propane is much easier to obtain.  The stoves can be converted from CNG to propane by calling Seaward with the serial # of your stove in hand.  Inasmuch as tons of boats have been produced with propane, I would tend to discount the "questionable" "questions about safety problems of propane" as somewhat of a potential overreaction.  If we were going somewhere that CNG was not as readily available as it is for us here (right down the street from our marina), I'd switch over.  Most C34s were built with propane, it's just the older ones, like ours, with CNG.  We get from 6 to 9 months a tank of CNG, less than $20 per swap out of tanks.

Jon
I also have the plans to assemble a adapter to fill cng tanks from auto cng stations, but can' t find any stations in my area.If you have stations in your area I will be glad to get them to you.Stu is lucky to have cng close,its probably costing more to research than change over to propane.

Al,

There are a good number of CNG refill stations in the DFW area, including one at DFW Airport. With changing computers in the last 2 years, I have lost/misplaced my contact information for them, but I will research it, recover it, and post it here after I find it.

Our 1988 C34 has CNG, and I would be interested in having the plans for the filler adapter.

Al,

Here is a search engine from the Dept of Energy that will locate available alternative energy fuel fill-up locations by city and state all over the US. There are 9 public CNG stations in the DFW area. Most of them are operated by Clean Energy.

If you can send the plans you have for the auto filler adapter in electronic format, please send it to me direct at jmnpe@flash.net.

Thanks.

I think that more than a few of us may be interested in a CNG filler adapter.  Would you consider posting the particulars/photos/specs on this site?  Thanks very much.   :thumb:

I'd be interested in that, too. 

For those who continue to refill, here's a handy link from Safgas:  http://www.safgas.com/index.php?action=website-view&WebSiteID=470&WebPageID=14067

Question for our Canadian brethren:  do any of you have CNG, and if so, where do you refill (especially on the West Coast -- Vancouver, Victoria Area)?
