Frequently Asked Questions
-
Can I add decorative logs or cover the burner ?
Do not obstruct the burner opening or the aperture. Under no circumstances, place ceramic logs or decorative items inside or around the burner.
-
What fuel should I use ?
Use high purity liquid bio ethanol (≥96%) designed for indoor fireplaces. Do not use gel fuel unless a page explicitly says otherwise
-
Do I need a chimney or a flue ?
No — these are flueless decorative appliances. Ensure minimum room volume and ventilation stated on the product page/manual
-
What run time should I expect ?
3–5 hours for 1.5 L burners Up to 8 hours at reduced aperture.
-
What output (kW) can I expect ?
Commonly quote up to ~2.3–3 kW depending on aperture
-
What about odour, CO₂ and ventilation ?
As with any combustion, bio ethanol consumes oxygen and produces CO₂ + water vapour; ensure room ventilation and use a CO alarm as good practice. Follow model specific minimum room volume
-
Are bio ethanol fires suitable for people with lung disease or sensitivities ?
They consume oxygen and produce CO₂ and water vapour (plus trace by products). If you have respiratory conditions, consult your clinician first. Always ensure good ventilation, avoid long runs in small rooms, and stop use if you feel irritation.
-
How much fuel should I add ?
Never exceed the manual’s maximum fill —check your model. Overfilling increases flare up risk and can make extinguishing difficult.
-
I hear “popping” sounds. Is that normal ?
Occasional soft pops can occur from vapour changes. Loud, repeating pops or pops accompanied by flame surges indicate a draft/fuel issue or abnormal combustion—document with video and contact support.
-
Why does condensation appear inside the glass door ?
Condensation appears because the OKO S1 releases water vapour during combustion, which settles on the cooler glass surface—especially at startup or in rooms with limited airflow. The recommended solution is to improve ventilation by opening a window, vent, or internal door so the moisture can disperse naturally and reduce build‑up otherwise the condensation should disperse naturally as it heats up.
