What to measure before ordering ↗The collection in detail
A 4-inch carrera marble fyre spheres look, with the component references beside it.
4-inch Carrera Marble Fyre Spheres brings a sculptural media format to the fireplace. Treat the sphere arrangement as part of the approved burner system: quantity, placement and the matching burner are not free design choices.
The priced selections shown here pair this family with G23 burner references where the manufacturer table documents compatibility. The available fuel choices are natural gas and propane. Controls listed in this family include on/off remote, electronic variable remote with on-demand pilot.
The practical boundary
Room heat comes with room requirements.
During vent-free operation, moisture and combustion products stay in the room. Fireplace approval, combustion air, room conditions and local rules must allow the appliance. This is a supplemental-heating choice, subject to the exact model instructions.
The nominal 18 / 24-inch labels describe the offered set sizes. They do not establish the minimum firebox width, depth or opening height. Different control assemblies can change the space required.

Before you choose 4-inch Carrera Marble Fyre Spheres.
What is included in the displayed product price?
The identified 4-inch Carrera Marble Fyre Spheres log or media set and its selected matching burner/control assembly. Customer sales tax, installation, delivery, optional accessories, gas-line work and chimney work are separate. The team confirms the complete scope before payment.
Can I choose another burner with the same nominal size?
Use the exact pairings shown in the selector. A similar nominal width or style name is not evidence of compatibility. The documented burner references for this family include G23. The exact manual and placement instructions still apply.
Does sending the request reserve this set?
No. Sending creates an unpaid order request for the components shown. Fireplace fit, supply and delivery or installation arrangements must be confirmed before the request becomes a fulfilled purchase.
What should I send for a fireplace fit review?
Record front and rear firebox widths, depth, opening height, fuel type and any appliance or fireplace rating plate. The project address helps the team review service coverage and local requirements. Keep the model references with the request.
