Converting LPG & Natural Gas Appliances
LPG (propane) and natural gas (methane) appliances are not interchangeable — they must be converted.
As a result of a move, you may have an appliance that you need to convert from natural gas to LPG or from LPG to natural gas.
LPG & Natural Gas Appliance Conversion Facts – LPG & Natural Gas Pressure
Natural gas and LPG appliances operate at different pressures, with natural gas pressure at 1.1 kPa and LPG at 2.75 kPa, respectively. LPG requires an air (oxygen) to gas ratio of approximately 25:1 whilst natural gas is 10:1, for proper combustion.
LPG has a higher energy content than natural gas, with 93.2MJ/m3 vs 38.7MJ/m3.
You can convert LPG to natural gas and natural gas to LPG. Natural gas to LPG or LPG to natural gas appliance conversions should only be done by qualified technicians or licensed gas fitters.

Natural Gas to LPG Conversion Kit – LPG to Natural Gas Conversion Kit
A natural gas to LPG conversion kit is typically available to convert all home appliances. You can also obtain an LPG to natural gas conversion kit for all appliances. For example, a natural gas conversion kit is used to convert an LPG gas BBQ to run on natural gas.
Manufacturers typically provide conversion kits with the parts and instructions required to convert from natural gas to LPG and vice versa.
These conversion kits could include different jets, burners and other relevant parts.
Can You Convert Propane to Natural Gas – Convert LPG to Natural Gas
You can convert propane to natural gas with most gas appliances, and vice versa. Convert a gas grill from propane to natural gas or a natural gas stove to propane is included in this flexibility.
To be sure, consult your owner's manual, look on the manufacturer's website or contact them directly.
Typically, some kind of conversion kit is required, even if just to change the size of the gas jets.

How to Convert a Gas Stove to Propane (LPG) – Use Propane on a Natural Gas Stove
You convert a gas stove to propane or a propane stove to natural gas. Many natural gas stoves and cooktops are shipped with a conversion kit to convert a natural gas stove to propane (LPG). The natural gas stove has propane jets installed in place of the natural gas jets.
Of course, you can use propane on a gas stove if it was made for propane or if you convert it from natural gas.
How do you convert a propane stove to natural gas?
The procedure is the same as to convert a gas stove to propane, just in reverse.
If the stove is new, it is probably already set up for natural gas.
If the stove has already been used for LPG, then the jets will need replacement with the natural gas jets.
BBQ Gas Conversion: Convert Grill to Natural Gas – Convert Propane BBQ to Natural Gas
With a propane to natural gas BBQ conversion kit, you can convert propane BBQ to natural gas. An LPG outdoor Grill or BBQ can be converted to natural gas. You just use the propane to natural gas BBQ conversion kit and connect it to your home natural gas supply.
Natural Gas Barbecue Hook Up – BBQ Gas Conversion to Convert LP Grill to Natural Gas
A natural gas barbecue hook up involves running a gas line from your home to the patio or other location of the grill as part of a BBQ gas conversion.
Can I Use Propane on a Natural Gas Water Heater
You can use propane on a natural gas water heater after it is converted to propane, as with other gas appliance conversions. The conversion would typically involve the burners and/or jets, as well as pressure adjustment, assuming the manufacturer can supply a kit for the conversion.
Different Incoming Pressure – LPG vs Natural Gas Pressure
A natural gas appliance requires a natural gas pressure of 1.1 kPa while an LPG appliance requires 2.75 kPa. This is controlled by the gas regulator that feeds the gas into your home.
Internal Pressure Adjustments
Original Design Must Allow for Both Gases
The manufacturer must have allowed for the changeover in the original design, with the appliance being tested and certified to use both gaseous fuels.
Depending on the appliance, there may be other parts that require changing, in addition to the gas injectors. Among these can be the burners themselves, dampers, aeration sleeves and air baffles.
Product labelling must also be changed. Most manufacturers sell the parts required for conversions of their more recent certified models.
You should contact the manufacturer to enquire about the availability of conversion parts.
