Bioethanol fireplaces offer an elegant, clean-burning alternative to traditional heating solutions — and unlike wood, gas or solid fuel stoves, they require no chimney, no flue, and no permanent structural connection. That said, installation still demands care, planning and attention to detail, particularly when it comes to safety, room size, and the correct building materials.
This guide outlines what you’ll need to consider before installation, how to meet UK regulations, and when to consult a Chesneys-approved installation partner.
MINIMUM ROOM SIZES
A bioethanol appliance emits water vapour and a small amount of carbon dioxide during combustion. These emissions are harmless in a suitably ventilated and correctly sized room, but it’s essential to meet the required room volumes for safe and effective operation.
The required minimum internal room volumes are as follows:
- FB18 & Salisbury Bio Stove – 25m³
- RB700 – 35m³
- RB1000 – 45m³
If you’re unsure whether your room meets these criteria, please speak to a member of the team. We’ll be happy to assist with calculations and offer tailored advice based on your chosen model.
MATERIAL REQUIREMENTS FOR BUILT-IN INSTALLATIONS
Where a firebox is to be recessed into a wall or bespoke joinery, all surrounding materials must be A1-rated and non-combustible. This includes any backing boards, structural framework, and finishing materials directly adjacent to the firebox.
Timber, MDF, plasterboard and other combustible materials must not be used within the constructed recess.
WHO SHOULD INSTALL THE FIREPLACE?
All Chesneys bioethanol fireplaces are plug-and-play by design — meaning no chimney, flue or permanent pipework is required — but that does not mean professional installation should be overlooked, particularly for inset or built-in models. Installation must be in accordance with the manufacturer’s guidelines which is why for clients undertaking full-room refurbishments or architectural integrations, we recommend using a Chesneys-approved installation partner. These contractors have direct experience working with our products and understand the necessary safety distances, fixing methods, and ventilation allowances.
Standalone models and fireboxes can typically be positioned and connected by the client or site team. However, if there is any uncertainty, our technical team is on hand to provide guidance.
ELECTRICAL CONNECTION
Bioethanol fireplaces from Chesneys require an electrical supply to power ignition, flame regulation, and safety sensors. A standard UK 3-pin socket is sufficient, and no dedicated circuit is necessary in most domestic settings.
Where the electrical socket is concealed behind the firebox or unit, please ensure access is available for future servicing.
MAINTENANCE AFTER INSTALLATION
To keep your fireplace performing at its best, we recommend a simple routine maintenance check:
- Use a vacuum with a soft brush attachment to clean the top plate and burner surface
- Inspect the burner channel for any dust, debris or obstructions
- Check that nothing is in contact with the internal safety sensors
- Replace the remote control batteries if required
- Use only Chesneys-approved bioethanol fuel for consistent performance
If you ever experience irregular operation, the issue is often linked to blocked burner vents or incorrect fuel.
INSTALLATION TIMEFRAME
A complete built-in or architectural installation can generally be completed within a day, depending on the site conditions and the readiness of the cavity. Standalone models require no fixings or construction and can be set up within the hour.
