Understanding Gas Appliance Conversions

Making changes to an appliance so that it can utilize a different fuel is known as appliance conversion. The inner Valves

and Orifices are designed to work with a particular gas that has a specific pressure. Natural gas is a much lower pressure

gas than propane and converting the appliance to one or the other gases requires that the differing pressure is

compensated for. In other words, connecting a natural gas appliance to a propane piping system will result in appliance

malfunction and possibly danger. The reason for this is because natural gas orifices are larger than propane orifices

strictly because of gas service pressure. In this case, the higher pressure gas flowing through a larger orifice will result in

more gas through the burner and likely, more flame...an unnecessarily large flame. Conversely, trying to use a propane

appliance with natural gas will likely result in a very small flame or no burner flame at all because of the lower pressure

gas and the smaller orifice. This is the underlying purpose of an appliance conversion from propane to natural gas or

from natural gas to propane.

GAS GRILL CONVERSION INSTRUCTIONS PAGE 2 OF 8 Conversions Between Natural Gas and Propane The following illustrated conversion can be used for when converting either from Liquid Propane to Natural Gas. This example is shown with the Barkman 4 Burner with Infra Red Burner. Other Grills without a IR Burner, can also follow this instructions, the only diffearance is you are not required to change any "Safety Valve" or "IR Orifice".

PAGE 3 OF 8 Conversions Between Natural Gas and Propane Before proceeding, make sure you have cleared away from grilling area any loose debris and secure a small box to place each screw in as you remove them. Locate a chair that has arm supports or other platform, and place this in front of grill giving you an elevated position to set the grills control panel after removal, this way you do not need to remove any wires, or other hoses.

Disasemble Valve Hose and Wires PAGE 4 OF 8 While pulling out the Control Panel Assembly notice the Flex Hose attached to Center IR-Valve, use Plyers to remove this from Valve Fitting. Also remove the Two Orange Ignition Wires from on top of the Valve. Try to keep the wires on the right valve connected. 6. Ignition Wires Flex Hose IR-Valve 7. 8.

When drilling, be sure to only press drill tip in no more than 1/4" Inch, or you may damage interior surface walls. #50 Drill Bit Hand Drill Do Not Drill This Valve 11. 10.

PAGE 6 OF 8 Test for Gas Leaks Mix some Soapy Water in a Bowl, use a Sponge to apply solution to these three areas illustrated. Afterward, turn gas flow on, and see if you see any Bubbling, or Smell any Gas, also make sure all Valves are turned OFF. If either is the case, tighten down all connections once more and test again untill there are Zero Gas Smells or Bubbling effects. 17. Apply Soapy Water Solution to these three areas GAS IN CHECK ALL CONNECTIONS Re-Install Control Panel 18.

If you do not use this burner, and are not concerned if the heat from it is less, it is also not required to convert this burner. The burner will still function and be safe to use, this is to your requirement if you decide to convert this burner from LP to NG gas type. A. 3 B.
