Co2 generator lpg to ng conversion?

I bought a LPG burner a while back and I’ve gotten that sick of hauling propane in the dead of night that I’ve considered tapping into my gas line.

I’ve tried doing a bit of searching but can’t find out if my burner can be converted?

Is it as simple as buying a natural gas regulator and using that instead of the propane regulator?

I would use a shutoff valve, then the regulator, then the co2 generator. Best to make sure the regulator has the proper flow rating in
cfh for the amount of btu the unit produces. The maker of the co2 generator usually sells a conversion kit / regulator. The outlet pressure in WC is the key.

The only reason to change the burners themselves is if you have a major altitude change.

It’s a pro leaf co2 burner. Decent quality and does its job but only now when I’ve searched for the manufacturer for the conversion kit I find that it looks like it is Chinese... I’ve emailed them hoping they reply but not a single hydro shop sells a conversion kit for it

dont forget pipe sizes... avoid having extra adapters

NO the spuds on the burner must be changed out for bigger ones NG only runs at half the pressure of LPG so the need for bigger spud to keep a nice blue flame.

This is correct.

Ya I have installed and converted 100s of gas appls,Never seen one where the spuds dont get changed out when converting from one gas to the other, might even have to do air adjustment on main burner tube.

I believe in all cases, it's the size of the orifice that you must change. That's the way my tri-fuel generator converts, It came with two orifices, one for NG the other for propane and a single regulator.


"The orifice is the hole that is drilled in the orifice plug. This is where the gas escapes from all your piping and enters the mixing bell of the burner. The orifice is not where the flame comes out of the burner.... that’s the head. Orifice plugs are the small nuts (with the hole in them) that are replaceable and screwed into the orifice spud. The orifice spud is the threaded piece that is attached to your piping." (from Ward Burner Systems... thanks)

But to safely and properly convert a liquid propane device to natural gas, the orifices need to be changed, as well as the regulator.

Hope this helps and is not redundant.

I have had LP gas models that were converted by manufacturer recommendation and all it was is the regulator. May be different with some models. Only time I have had to mess with the burner orifice is when going high altitude.

Thanks for the input guys.

If the manufacturer doesn’t sell the conversion kits can you recommend what I need to buy? Are these things I need universal?

Iam not 100% sure on what opp has but I have never done a conversion without changing the spud an Regulater an most gas burners have a air ajustment on the main burner tube that needs to be set for what ever gas is being used.

I’ve tried searching but one thing I can’t find out is if every type of gas appliance is different.

I can find information on for example gas hobs... but I am fairly sure it won’t translate to my pro leaf co2 burner.
I’m waiting for a response from the manufacturer too.

The orifice-spud should have a # on it for size,Is the regulater inline or mounted on the unit.

I don’t think it has a regulator? For lpg I think the regulator goes directly onto the tank?

Here’s the photos of it

Maybe time to get a new unit and sell that one on CL so someone can just use it with propane.
