The gas log heater is fitted with a specially designed
safety pilot (ODS assembly) which senses the amount of
oxygen available in the room and shuts the gas log heater
off if the oxygen level begins to drop below a satisfactory
level. The pilot can only be relit when adequate fresh air
is available.
