Choose a Safe Location
The first step to using a chimenea safely is choosing the right location.
Your chimenea should always be placed:
On a flat and stable surface
At least 2–3 metres away from buildings
Away from fences, sheds and trees
In a well-ventilated outdoor area
Avoid placing a chimenea directly on wooden decking or grass, as the heat and sparks can cause damage.
Using a chimenea floor protector or heat mat is recommended to protect patios and decking.
Use the Right Fuel
Choosing the correct fuel helps ensure safe and efficient burning.
Common fuels for chimeneas include:
Dry seasoned firewood
Charcoal
Heat logs
Avoid burning:
Treated or painted wood
Wet or green wood
Household rubbish
Plastics or chemicals
Using dry wood produces less smoke and reduces soot buildup.
How to Light a Chimenea Safely
When lighting a chimenea, it is important to build the fire gradually.
Step-by-step method:
Place firelighters or kindling inside the chimenea.
Add a small amount of dry wood on top.
Light the firelighters.
Allow the fire to establish before adding larger logs.
Never overfill the chimenea with wood, as this can cause excessive heat or sparks.
Keep the Fire Controlled
A chimenea is designed to contain the fire, but it should still be monitored.
To keep your fire safe:
Never leave a lit chimenea unattended
Keep children and pets at a safe distance
Avoid using a chimenea during strong winds
Do not overload it with fuel
Always keep a bucket of water or sand nearby in case you need to extinguish the fire quickly.
Protect Your Patio or Decking
Heat and falling embers can damage surfaces such as:
Wooden decking
Composite decking
Grass or lawns
Stone patios
Using a chimenea floor protector or heat shield can prevent stains and heat damage.
Allow the Chimenea to Cool Properly
After use, allow the fire to burn down naturally.
Never pour water directly onto a hot clay chimenea, as rapid cooling may cause cracking.
Instead:
Let the embers burn out naturally
Allow the chimenea to cool completely before cleaning
Maintain Your Chimenea
Regular maintenance helps keep your chimenea safe to use.
Maintenance tips include:
Removing ash buildup regularly
Keeping the chimenea dry when not in use
Using a cover during wet weather
Checking for cracks or rust
Proper maintenance also extends the life of your chimenea.
