Cleaning & Maintenance
Keep your system clean, safe and efficient
A well-maintained stove and flue system performs better and lasts longer. Regular care improves efficiency, reduces fire and carbon-monoxide risks, and helps protect the appliance.
WHAT TO CLEAN & HOW OFTEN
Wipe the exterior with a soft dry or slightly damp cloth. Use only non-abrasive products and keep air vents clear.
Clean only when cold using stove-glass cleaner and a soft cloth. Avoid abrasive materials.
Empty regularly without overfilling, only when the ash is completely cold. Use a metal container with a tight-fitting lid.
Arrange professional sweeping at least once each year to remove soot, tar and creosote build-up.
Check and clean air vents and controls, ensuring they move freely.
Check that it is secure, clear of leaves, nests or debris, undamaged and operating correctly.
RECOMMENDED CLEANING TOOLS
- Stove brush and shovel for ash and soot
- Ash vacuum for completely cold ash
- Cleaner specifically suitable for stove glass
- Soft, non-abrasive microfibre cloths
SIGNS IT’S TIME TO CLEAN
- Stove glass blackens quickly
- Poor heat output
- Smoke or fumes enter the room
- Strong tar or smoky smells
- Soot build-up in the stove or flue
- Bird nests or debris in the cowl
SEASONAL MAINTENANCE CHECKLIST
Sweep chimney and flue; check cowl and terminal; inspect stove body, door seals and glass; clean air vents.
A good time for servicing and repairs; inspect seals and rope; check wear and damage; keep the flue sealed from moisture.
Clean stove and flue before heavy use; check dry fuel supply; test controls and vents.
Remove ash regularly; check glass and vents weekly; burn the correct fuel and control the air.
Use dry seasoned wood below 20% moisture or smokeless fuel authorised for the appliance.
Allow the stove to cool fully before cleaning. Never use water on a hot stove or inside the flue.
Cleaning improves efficiency and can extend appliance life.
A clean system burns more cleanly, produces more useful heat and uses less fuel.

DOWN-DRAUGHT CAUSES
WHY WIND CAN PUSH SMOKE BACK INTO THE HOME
Down-draught occurs when wind pressure or turbulence pushes air back down a chimney instead of allowing combustion gases to rise safely.
How down-draught develops
A chimney termination that is too low or badly positioned in relation to the main roof apex can sit within turbulent airflow. This can reduce flue draught, cause poor appliance operation and allow smoke or carbon monoxide to enter the home.
Roof and terminal position
- The termination is too low in relation to the main roof apex.
- Nearby roof shapes or taller structures create wind turbulence.
- The terminal type is unsuitable for the appliance or location.
Surrounding landscape
- Cliffs or elevated land can create turbulent airflow, especially on the lee side.
- Rolling hills and valley locations can produce changing wind patterns.
- Nearby trees, tall vegetation or buildings may disrupt airflow around the terminal.
Common warning signs
- Smoke spilling into the room.
- Difficulty lighting the fire or keeping it drawing.
- Poor burning performance.
- A smell of smoke, particularly during windy weather.
- A carbon-monoxide alarm sounding or occupants feeling unwell.
What should be checked
- The whole flue for blockage, damage, contamination and correct sizing.
- The appliance air supply and permanent room ventilation.
- Terminal height and position against current Northern Ireland requirements.
- The effect of the roof, local terrain, nearby buildings and vegetation.
Possible remedies after diagnosis
- Correcting or extending the chimney termination where appropriate.
- Using a suitable anti-down-draught terminal only after the cause is established.
- Managing nearby vegetation where this can be done safely and lawfully.
- Completing any necessary sweeping, flue repairs or ventilation work.
Why professional assessment matters
- Similar symptoms can also be caused by blockage, inadequate ventilation or flue defects.
- A cowl is not a universal cure and the wrong terminal may create further problems.
- The complete appliance and flue system should be assessed before remedial work is chosen.
Persistent draught problems require a site-specific inspection so the cause can be identified and any work remains compliant with current Northern Ireland Building Regulations.
