How can I convert a Broil King Signet 320 from natural gas to propane? Is it possible?

thanks.

Only two ways that I know to complete this task.  Buy a new LP manifold designed for that specific model and a supply hose with regulator.  The other way is to replace the orifice for each burner.  THis may not be possible as some are not removable.  But if they are removable, you would need the equivalent size of LP orifice to replace the natural gas orifice.  And you would need a supply hose with LP regulator.  Not complicated if you know what you are doing.  You might call an LP supplier and ask for assistance.

Thanks.  I assume I could use a hose and regulator from an old propane BBQ.  I think they would be universal.  It's the changing and size of the orifice I am not sure about.  I emailed the manufacturer to see what they say.

This is what they want to sell me.  I"m sure I could use the hose off my old propane BBQ.  They won't sell me just the orifice due to safety reasons.  If only I knew the orifice size to buy.  Or If I could take the ones out of my old propane bbq.

Check out the link below.  Also note they have a "contact us" link on the website.  It might be beneficial to send them your question about the conversion.  Info that you will need to provide would be:  the BTU rating of the grill and the number of burners control valves that the grill has.  I would assume that you can use the hose and regulator from another LP grill if the connections are the same size from one grill to the next.
