Replacement Orifice for Repairing and Converting Turbo BBQ Rotisserie.

The barbecues we see in a lot of backyards carrying the name Turbo were made by a lot of companies throughout the years. In fifteen years of selling, servicing and repairing grills we do not know of a Turbo that was manufactured in America. American companies will usually have replacement grill parts readily available but most of the barbecues that are imported do not make parts for repairs. The companies go out of business too often. The replacement orifice used to convert the infrared rotisserie burner in several Turbo models has long been difficult to locate. A new orifice is necessary for the BBQ grill when we are converting the barbecue from one gas type to another type of gas. Recently we came across this orifice that has the same threads and a similar enough design to properly fit inthe the infrared burner venturi.

Orifice from Turbo rotisserie. The rotisserie valve has a gas line attached in the control panel and the orifice screws to a compression or flared fitting at the back of the BBQ where it enters the rotisserie burner venturi. If you are converting the gas type for your Turbo gas grill this is the rotisserie orifice. Look at your orifice to be sure.

Gas Orifices Define BTU.

The orifice in the valve restricts gas flow just slightly enough to define the BTU of the burner. Depending on the type of gas a different diameter opening allows gas flow. The same orifice can be used on different grills and the same orifice can be used for Natural Gas and Liquid Propane but the opening will be very different between NG and LP and different BTU flow.

Although this pointy orifice is often unavailable, there are several alternatives shown here that we use as replacements.Orifices come new without an opening and need to be drilled to the specific diameter which is determined by the Regulator. Select a regulator with your orifices so we can drill the orifices to match the regulator you select.

Available Replacement Orifice

That original orifice is from a NG Turbo gas barbecue grill gas line attaching the control valve to the infrared rotisserie burner. If the gas line needs to be replaced you can buy the compression fittings and length of gas line also. Blog instructions for installation.

This Other orifice in the image (newer quarter) is the replacement orifice we use. Although this orifice looks a little bit different the threads are the same size and the same threading and although the replacement orifice is not triangulated the tapered design allows this orifice to insert into the rotisserie venturi.
This will fit the gas line from the control valve and this replacement gas orifice will insert into the rotisserie to work in the barbecue.

If you Select A Regulator For Natural Gas or Propane With The Orifice, we can drill the proper diameter in the orifice before we ship it to you but Orifices Must Be Matched To A Regulator Because Pressure Determines The Opening Size.

Although infrared the rotisserie burner is usually designed to pull less gas than a typical pipe burner. The typical barbecue pipe burner pulls approximately 13,00 BTU and the typical grill burner pulls about 24,000 BTUs. The infrared rotisserie burner will usually pull approximately 10,000 BTUs. In the main barbecue there will typically be three or four burners that will heat the cooking area to approximately 450 degrees if the hood is left closed for ten to fifteen minutes. By contrast the rotisserie burner will pull less gas and can cook food on the spit immediately because the infrared burner is designed to use gas much more effectively.

Most clients contact us for an orifice because thet need to convert a gas appliance to an other type of gas. The difference between a grill burning propane and a grill burning natural gas is the orifices are different and the regulator is different. These are the items that change when a barbeque is converted. LP stands for liquid propane because propane in a portable cylinder is a liquid. At the inner circumfrence of the cylinder liquid propane vaporizes (boils and nbecomes a gas like water becomes steam) into its gaseous state. Propane is still very cold which makes the molecular make-up much denser than natural gas. Natural gas orifices have a huge opening compared to the small LP opening in an orifice but both will produce the same amount of heat.
