Gas Conversion From LP to NG
This grill is portable and configured for use with Liquid Propane (LP Gas), which is delivered to the grill from
removable tanks (LP tanks and their use are covered elsewhere in this manual). If a Natural Gas connection is
available, the user may wish to change the gas delivery system to the more permanent Natural Gas supply.
This grill is certified for use with either Liquid Propane (LP Gas) or Natural Gas and comes complete with the
necessary parts to convert the grill for use with Natural Gas hose and regulator sold separately. The Nexgrill
patented Conversion Valves allows the use of Natural Gas without replacing the burners or entire valve
system.
The process of converting is relatively simple and can be accomplished by any handy homeowner. Nexgrill
suggests, however, that a qualified gas technician do the conversion. Your warranty may be voided if the
conversion is improperly completed. Please retain the parts supplied with the grill and these instructions so
the technician can do the conversion.
Orifice Chart
The different burner valves in this grill have different BTU ratings. This means that the quantity of gas coming
from each orifice varies in order to create the BTU's. The holes in the orifices themselves are drilled to
different sizes as to allow the proper amount of gas to flow through them. Please note the chart below to give
an easy reference for the various orifice opening sizes for the different valves in the grill.
