What Safety Devices Are Fitted To Flueless Gas Fires?

All modern flueless gas fires manufactured and sold in the EU have an ODS pilot system fitted. This special part monitors the oxygen levels in the room. If the air vent is blocked the ODS will shut off the fire long before there is an issue over the emissions. For instance our fire shuts down at only 25ppm, the CE maximum is 80ppm and it is reported that exposure to CO of levels of 800ppm and higher are considered hazardous. Most CO alarms go off at 36ppm to 99ppm when sampling the concentration in the room. This means your cvo flueless gas fire will go switch off “before” the CO alarm goes off.
