Pressure first

Liquid Gas UK Consumer Guidance Sheet 39 describes UK propane regulators as typically providing a nominal 37 mbar at the appliance, with butane commonly 28–30 mbar. Never force a regulator onto a valve it was not made for. None of the nine listings in this capture prints an outlet pressure in mbar. If the manual states 37 mbar propane, match the regulator and cylinder valve to that figure. If the page is silent, do not assume a US tank hose fits a UK bottle. Mixing butane settings onto a propane appliance is poor flame and unsafe operation, not a workaround. Read the words that actually appear: UK regulator, patio gas, 5 kg tank, 20 lb cylinder, POL, or only LPG hose. The comparison cannot invent a mbar line that was never there. Form and heat sit on the outdoor gas fireplace buying guide.

Clip-on patio gas versus screw-in propane

Green patio-gas cylinders commonly use a 27 mm clip-on regulator. Red propane bottles more often use a screw-in POL connection. Both can be propane. The valve shape is what stops a forced fit. Calor’s patio-gas FAQ often points smaller and tabletop heaters toward 5 kg bottles and larger heaters toward 13 kg. That is a size hint for a fire pit table bay, not proof that a given hose is the right clip-on. Suppliers such as Bullfinch sell 27 mm clip-on regulators marked 37 mbar. The Outsunny table names a bottom bay for a standard 5 kg tank, with regulator and hose pre-assembled, still without a printed mbar. The Onlyfire 18-inch title says a UK regulator and lists a 1.9 m hose. Confirm the valve on the bottle you own. Never file or heat a regulator to make it fit.

US 20 lb language in this folder

The Outland Living Firebowl 893 includes a pre-attached 10 ft hose and adjustable regulator for a standard 20 lb cylinder, which is not included. It prints 250 PSI as max gas supply pressure and names CSA. CSA is not UKCA. 250 PSI is a maximum supply figure, not the 37 mbar operating setting. Liquid Gas UK warns against using US POL regulators with UK cylinders because the fittings differ. Those lines are buying flags: source a correct UK regulator and hose, or choose a listing that already speaks patio gas, before you count stars. The cheapest pan says UK regulator in the title while sharing review bodies with another ASIN. Do not turn that title into a 37 mbar figure that was never printed. Price and stars, once fittings are settled, are on best outdoor gas fireplace.

What is DIY and what is Gas Safe

Connecting a portable cylinder appliance outdoors, with the correct regulator and a clean leak test, is normal owner work when the parts match. The Gas Safety (Installation and Use) Regulations 1998 generally leave many cylinder-fed portable appliances outside the piped-meter installation rules, with caveats for certain space heaters. That is not a substitute for HSE L56 if you are a landlord. A new pipe from the house gas meter, a natural-gas conversion, or a leak that shutting the cylinder does not stop is Gas Safe work. Optional conversion kits on some North American bowl pages are not a UK patio project. If the connector pin will not depress the valve, or gas is intermittent, replace the connector or call a Gas Safe engineer. Store cylinders outside, change them outdoors, and shut the tap first, as GOV.UK describes.

Common questions

What pressure should the regulator be?
UK propane appliances typically expect a nominal 37 mbar at the appliance, per Liquid Gas UK Sheet 39. Butane is commonly 28–30 mbar. Follow the figure in your product manual when it is printed. None of the nine listings in this capture prints an outlet pressure in mbar, so a silent amazon.co.uk bullet is not a 37 mbar claim.
What is a 27 mm clip-on?
It is the common regulator connection for green UK patio-gas cylinders. The regulator clips onto the valve rather than screwing on like many red propane POL fittings. Both can be propane. The valve shape is the mismatch. Never force a regulator onto a valve it was not made for.
Is patio gas the same as propane?
Patio gas is propane sold in leisure cylinders with a patio valve. The gas family matches propane service. The valve and the regulator shape are what must match your hose. A green bottle and a red POL bottle are not interchangeable fittings just because both are propane.
Will a US 20 lb hose fit my Calor bottle?
Not automatically. US POL and UK patio clip-on fittings differ. Liquid Gas UK warns against forcing US regulators onto UK cylinders. The Outland listing’s 20 lb hose and 250 PSI line are not a 27 mm clip-on and not 37 mbar. Check before purchase or first light.
Which bottle size fits a table bay?
In this capture the Outsunny table names a standard 5 kg tank bay. Confirm the bay against your bottle’s height and diameter. Calor’s patio-gas language often points larger heaters toward 13 kg, which may need to stand beside the unit rather than inside a small bay. The cylinder is not in the box.
When is Gas Safe required?
For a leak that remains after the cylinder is shut, for a damaged connector you cannot replace safely, and for any work on piped natural gas. The 1998 regulations generally leave many cylinder-fed portable appliances outside the piped-meter installation rules, with caveats for certain space heaters. If you are a landlord, HSE L56 is the document to read, not this page alone.
