PILOT
The gas log heater is fi tted with a specially designed safety
pilot light (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 re-lit when adequate fresh air
is available.

THERMAL GENERATOR

The millivolt gas log pilot is fi tted with a millivolt generator
to provide power for remote activation.
