Gas Supply Conversion and Orifice Replacement Guide
PURPOSE:
If a barbeque or side burner unit is to be operated with a different gas supply other than the one
provided by the factory, a conversion kit is required. This change must be done in order to ensure that:
• The unit is safe to operate.
• The unit has correct combustion of gas.
• The unit outputs the expected heat (BTUH’s).
• Your warranty is maintained.
By changing from Natural Gas (NG) to Liquid Propane (LP) or vice versa, the heat output as well
as the regulating pressure and oxygen content of the gas/air mixture also changes. Therefore a change
in orifice (gas injector) size is required, (usually larger or smaller depending on the application), as well
as a change in the main pressure regulator setting to allow for proper gas pressure to the valves and
burners.
On the next pages you will find the necessary information to replace orifices, adjust burners and
convert pressure regulators to suit your application. This information is generalized due to the different
models manufactured, nevertheless it applies to all of them in the same fashion as it indicates the loca-
tion and how to access orifices and regulators.
For additional information, all conversion kit numbers and components are listed at the end of this
guide in the appendix section.
WARNING:
As the unit will be partially disassembled during gas supply conversion and orifice replacement, it
is necessary to remove all power sources to the unit (including but not limited to: barbeques lights, rotis-
serie motor and igniter module batteries) as well as all gas supplies (Natural gas or Liquid propane).
Alfresco Gourmet Grills recommends a qualified gas technician to perform this service.
