Frequently Asked Questions
What gas do outdoor fire inserts use?
Most outdoor gas fire inserts use propane (LPG) or natural gas, depending on the model. Propane is the most common choice for garden installations as it is supplied via a cylinder and does not require a mains gas connection. Always check the manufacturer's specifications and use the correct regulator and gas type.
Can I install a gas fire insert myself?
While some gas fire inserts are designed for straightforward DIY installation, we strongly recommend having any gas appliance installed and checked by a qualified Gas Safe registered engineer. This ensures the installation is safe, compliant and covered by any applicable warranty.
What size gas fire insert do I need?
The size of gas fire insert you need depends on the dimensions of your fireplace opening and the heat output required. Measure the width, height and depth of your fireplace opening carefully and compare against the product specifications. Larger inserts produce more heat and a more impressive flame display, but must fit safely within the fireplace structure.
Do gas fire inserts need a flue?
Requirements vary by model. Some outdoor gas fire inserts are designed for open-air use and do not require a flue, while others may need ventilation or a flue system depending on the installation environment. Always check the manufacturer's installation requirements and consult a qualified engineer if in doubt.
