Ensure you have read and fully understood the instruction manual and safety advice before using this product.
This product is intended for outdoor use only; do not use indoors or in enclosed or partially enclosed spaces, including conservatories, tents, garages or under awnings.
Do not use the gas firepit under any covered area unless it is certified for open-flame use and provides sufficient ventilation; risk of carbon monoxide buildup can be fatal.
Ensure the firepit and seating are placed on a level, stable, non-flammable surface such as concrete, stone or patio slabs; never place on grass, decking, or other combustible surfaces.
Keep the firepit at least 1.5 metres away from buildings, structures, low-hanging branches, overhangs, or flammable materials including fences, umbrellas, and soft furnishings.
Position the gas hose securely and route it away from walkways or areas of foot traffic to prevent tripping hazards; never allow the hose to become kinked or twisted during use.
Do not modify, adapt or reposition the furniture set or firepit in a way that may compromise its stability or obstruct proper ventilation.
Regularly inspect the modular seating connections to ensure all parts are secure and level, with no shifting or gaps that may present a fall or pinch risk.
Do not overload individual seating units; maximum weight capacity per seat is 120 kg (approx. 19 stone).
Keep children and pets under strict supervision around the firepit at all times; the flame and surrounding surfaces can cause serious burns.
Never leave the firepit unattended while it is in operation or still hot.
Only use gas cylinders that are compatible with the firepit as specified by the manufacturer; incorrect cylinders can cause leaks or malfunction.
Always check for gas leaks using an approved leak detection method (e.g. soap solution) before each use; never use a flame to test for leaks.
Turn off the gas supply at the cylinder immediately after use and disconnect the cylinder if the firepit will not be used for an extended period.
Store gas cylinders upright, outdoors, and away from direct sunlight, sources of ignition, or extreme heat.
Keep all cushions and upholstery at a safe distance from the flame, and avoid operating the firepit in strong winds that may cause the flame to shift unpredictably.
Do not place or lean flammable items, clothing, or accessories on or near the firepit table at any time.
Use the glass wind guard provided at all times while the firepit is in operation to help contain the flame and reduce the risk of accidental contact, while understanding that it does not eliminate all burn hazards.
Allow the firepit and its components, including the glass guard and table top, to cool fully before touching or covering them.
Use heat-resistant gloves when removing or handling any parts that may retain heat after the firepit has been in use.
Do not use the firepit in wet or rainy conditions, and ensure the gas control compartment is dry before lighting.
Perform regular inspections of all gas connections, ignition system, frame integrity, and firepit hardware before each use.
If the firepit does not ignite immediately or the flame goes out unexpectedly, turn off the gas and wait 5 minutes before attempting to relight.
Do not operate the firepit while under the influence of alcohol, drugs, or if fatigued.
Cover the firepit with a flame-retardant, weatherproof cover only once all parts have cooled completely.
Use only replacement parts and accessories supplied or recommended by the manufacturer; unauthorised components may cause unsafe operation and void any warranty.
Ensure safe storage of all cushions, covers and loose items when not in use to prevent damage from weather and reduce fire risks.
In the event of any malfunction, strong gas smell, or signs of overheating, shut off the gas supply immediately and contact a qualified technician; do not attempt to repair the firepit yourself.

Troubleshooting
23. Maintenance
Regular maintenance is essential to ensure the continued safety, structural stability and safe gas operation of your 7 seater modular gas firepit sofa set. The following procedures support the control measures identified in the product risk assessment and must be carried out routinely.

General Structural Maintenance (Modular Seating)

Inspect all underside joining screws and interconnecting fixings at least every 3 months and after any relocation. Tighten securely to prevent separation of modules and reduce instability or trip hazards.

Check that all seating sections remain level and correctly aligned around the firepit table. Uneven positioning may create instability or stress on the frame.

Examine metal frames for corrosion, cracking, distortion or weld fatigue. Discontinue use if structural damage is identified until repaired or replaced.

Clean metal frames using mild soapy water and a soft cloth. Do not use abrasive cleaners, solvent-based products or pressure washers.

Ensure adjustable feet (if fitted) remain secure and provide even ground contact.

Cushion Maintenance

Regularly inspect cushions for heat exposure damage, scorch marks or fabric degradation.

Ensure they remain correctly placed a safe distance away from the fire and are not pushed into contact with the firepit table.

Store cushions in a dry, ventilated area when not in use to prevent moisture damage and mould growth.

Allow cushions to dry fully before reuse if exposed to rain.

Replace any cushion showing signs of fire damage, excessive wear or filling displacement.

Gas Firepit and Table Maintenance

Before each use, visually inspect the gas hose, regulator and all connection points for wear, cracking or deterioration.

Perform a gas leak test periodically and after every cylinder change using an approved leak detection solution (never use a naked flame).

Ensure burner ports are clean and free from debris, insects or blockages. Clean gently with a soft brush only when the unit is fully cool and disconnected.

Inspect the ignition system regularly to ensure reliable operation.

Clean the burner tray and media area of dust, debris or water accumulation to prevent uneven flame distribution.

Check that the glass wind guard is clean, correctly positioned and free from cracks or chips. Do not operate the firepit if damaged.

Allow the firepit to cool completely before fitting any protective cover.

Ensure the table surface remains stable and secure with no looseness between the firepit housing and table structure.

Gas Cylinder and Hose Maintenance

Always store the gas cylinder outdoors in an upright position, away from heat sources and direct sunlight.

Disconnect the cylinder when the firepit is not in use for extended periods.

Inspect the hose routing to ensure it does not create a trip hazard around the seating area.

Replace hoses showing signs of abrasion, UV degradation, cracking or stiffness.

Seasonal and Long-Term Storage

Thoroughly clean and dry all components before extended storage.

Store in a dry, covered location where possible.

Use a breathable protective cover only after the firepit has completely cooled.

Before re-use following long-term storage, conduct a full inspection of structural fixings, burner condition and gas connections.

Replacement Parts and Modifications

Use only manufacturer-approved replacement parts for gas components, ignition systems and structural fixings.

Do not modify the firepit burner, gas system, table housing or seating connection system.

Do not drill, weld or alter the frame structure, as this may compromise stability and invalidate warranty.

Failure to carry out regular inspection and maintenance may increase the risk of gas leaks, fire, burns, instability or structural failure and may invalidate the manufacturer’s warranty.
