Gas Conversion From LP to NG

WARNING
MAKE SURE ALL CONTROL KNOBS & CYLINDER VALVE ARE IN OFF POSITION BEFORE CONVERTING.
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 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. We
suggest, 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. The holes in the orifices themselves
are drilled to different sizes so 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.

WARNING
Make sure all grill components are completely cooled and gas supply is turned off and
removed from grill prior to performing the conversion.
1．Install the regulator hose (short hose) to the end of the regulator marked "OUT." Install the brass
connector to the other end of the regulator marked "IN." (If regulator, hose, and brass connector are pre-
assembled, you may disregard this step.)
