LPG Appliance Conversion
You only need to change the (1) gas oriface that feeds the appliance valves.
LPG is Specific Gravity 1.4...CNG is SG .85...Air is SG 1.0
LPG is heavier that air and has more BTU per Cubic Ft.
So...the oriface needs to be SMALLER. Check with the MFG for an LPG oriface.
Should be a common part.
Of course you need all the LPG System Safeties.
Airtight Tank Locker
Solenoid Shut-Off inside Cabin
LPG Monitor at floor level
CO Monitor / Fire Detector
And most importantly....commercial level valves, fittings and hoses.
LEAK TEST ALL CONNECTIONS with 50%water/50% dishsoap in spray bottle.
Clean off ALL SOAP solution with water in spray bottle. Soap residue is
CORROSIVE and will cause premature fitting failure.
Get the parts from an LPG Supplier...not Home Depot or ACE !
The fittings and hose are also available at Industrial Hydraulic Suppliers. Fittings are SAE Flare...same as used on hydraulic lines for Backhoes.
Gas Hose needs to be USCG Rated with factory compressed fittings.
The custom hose/fiittings can be made at all Industrial Suppliers.
DO NOT use barb fittings with hose clamps for gas feeds. OK on VENTS.
Support ALL hoses tight to structure every 12" with NO sags.
LPG has proven to be a very dangerous installation in the WRONG HANDS.
That is why the parts are not readily available at Retail Outlets.
Some states require a Plumbing License just to buy the parts due to liability !
A successful installation can be done by working slowly and being methodical.
Good Luck
