Converting to CNG

My Nassau 34 was originally set up w/CNG. someone converted to propane. They vented the locker at its lowest point, but the problem is that on starboard tack that vent is submerged meaning it is not functioning. The locker is such that it can only, using propane, be vented this way. It seems sensible to revert to CNG. Will the stove/oven work with either? Is there a different regulater needed for CNG or is it the same as propane.

CNG is available in my area, but what if I take the boat to the Carribean?

Converting to CNG

Changing cooking fuels is a very extensive project, in that the tanks, the tank locker, the hose, the regulator, and the burner orifices must be changed.

LPG is heavier than air, and lockers are vented BELOW the cylinder (ABYC A-1 - .1.8.4)
CNG is lighter than air, and lockers are vented ABOVE the cylinder (ABYC A-22 -.13.4)

For information on the installation of liquefied petroleum gas (LPG) or compressed natural gas (CNG) systems, galley stoves, and heating systems see NFPA-302 (Fire Protection Standard for Pleasure and Commercial Motor Craft) or American Boat and Yacht Council, Inc. (ABYC) Projects'' A-l, A-3, A-7, and A-22. Also NFPA 54 (National Fuel Gas Code) can provide additional guidance but where this code conflicts with NFPA 302 or ABYC, due to marine constraints, the latter take precedent.

Give Corp Brothers a call. They will help you through the transition. Corpbrothers.com
From what I have been told the farther south you get the harder CNG is to get. Many Morgan owners have switched because of the problems getting the CNG.

Wow! Thank you for the great info. I may be looking for a tank, but first I have to complete my research on this.
