It includes the standard 10″ air tube, direct spark ignition, and a 120V control system and gas valve. Best for upgrading larger capacity boilers without moving to a fundamentally different burner system.
Who this is for: facilities that require higher BTU output from a gas-converted system and want reliable ignition with simple electrical control.
Limitation: higher BTU ranges may necessitate diffuser plate configurations and proper calibration to maintain efficient combustion.
Bullplus Propane To Natural Gas Conversion Kit
This universal conversion kit allows converting a propane system to natural gas with brass orifices and nozzles designed for safe, regulated gas flow. It is ideal for outdoor cooking appliances, Blackstone griddles, and similar setups that require permanent natural gas access. Best for easy, DIY conversions where a permanent fuel line is preferred over tanks.
Who this is for: users seeking a straightforward, durable kit to achieve propane-to-natural-gas flexibility on compatible outdoor cooking or heating surfaces.
Limitation: verify compatibility with your specific model and ensure proper installation to avoid gas leaks or improper flame control.
GRLP4 LP Gas Conversion Kit for Natural Gas to Propane
The Natural Gas to Propane Conversion Kit GRLP4 is a complete 12-piece set with brass orifices for reliable propane flow in conversion projects. It is designed for ranges, cooktops, and similar appliances and is compatible with several GRLP4-type conversion setups. Best for kitchen appliances where precise propane calibration matters for consistent burner performance.
Who this is for: homeowners or installers converting compatible gas ranges or cooktops from natural gas to propane, with a focus on precise jet sizing for stable flame output.
Limitation: ensure that your model falls within the GRLP4 family and follow all safety and local code requirements during installation.
Buying Guide: How to Choose The Right Oil-To-Gas Burner
- Fuel compatibility and BTU needs: Match the burner’s input range to the boiler or heater’s load. For variable loads, universal EZGas models with diffuser plates offer flexible performance.
- Installation requirements: Many of these units require licensed installation for warranty and safety. Check if your system needs diffuser plates, air tubes, or specific mounting hardware.
- Ignition and controls: Direct spark ignition and 120V control systems simplify operation but ensure electrical compatibility with existing wiring.
- Efficiency and emissions: Higher-efficiency burners can reduce fuel use, but only if properly tuned to your fuel type and venting. Consider environmental impact alongside cost savings.
- Maintenance and parts availability: Choose brands with readily available diffuser plates and replacement parts to minimize downtime.
Frequently Asked Questions
- What is an EZGas burner?
Answer: A direct-spark ignition burner designed to convert from oil to natural gas or propane, with configurable BTU ranges and often diffuser plates for multi-range operation. - Do I need a professional to install these burners?
Answer: For most models, yes. Professional installation ensures correct gas supply connections, diffuser plate use, and warranty validity. - Can a propane-to-natural gas kit be used on any grill?
