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.

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". For converting gas
types, it is extremly important to follow these instructions step by step, we always reccomend a Licenced Plumber or
Installer perform any maintence or gas conversion on your grill.

Island Safety Vent Installation for either Liquid Propane or Natural Gas

For Natural Gas

Natural Gas (NG) is Lighter and will raise to
upper end of structure upon leak. Outdoor
Kitchen Islands housing Natural Gas Appliance
must have several vents located at the
approximate level as the Appliance Control
Panel, were Knobs are located.

For Propane Gas

Liquid Propane Gas (LP) is Heavier and will
lower to base of structure upon leak.
Outdoor Kitchen Islands housing Propane
Gas Appliance must have several vents
located within 4" to 6" from ground level.

IMPORTANT!! - USE CORRECT GAS REGULATOR FOR EACH GAS TYPE

For Liquid Propane

Your new Grill is set as
Liquid Propane (LP), which
uses the Medium Pressure
Regulator supplied your
your gas grill appliance,
designed for portable tanks.

For Natural Gas

When converting your grill
to Natural Gas, be sure to
remove the LP Regulator, and
install this NG Regulator in it's
place, reccomend to have
licenced plumber make final
gas connections.

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. In step "4", there are two pins that are holding the control panel in place, you will
need to wiggle the control panel for it to drop down, sometimes angling it then pulling down will also release it were
the valves are inserted in burners.

While removing Control Panel Assembly, it may be necessary to tilt back and forth,
while pulling down, as there are two PINS holding control panel to Grill Frame.

4. Remove the Small Center Knob

After removing the center small knob, the same one for
the back Infra-red Burner, also remove ONLY the Top and
Bottom Screws. This will release valve from control
panel, but still keep it afixed to the gas manifold pipe.

5. Slide out Control Panel

Grip base of control panel firmly, and first pull down and
out releasing the two pins inserted into grill control panel
frame. (See illustration below)
