IGN
- Valve position to light/maintain a standing pilot.
ON
- Valve position to turn ON/OFF log set with remote switch/thermostat.
LOW/HI
- Variable position to control flame height (heat output). Both front and rear burners are in operation
to provide realistic glow and yellow flame.
PILOT
The gas log heater is fitted 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 relit when adequate fresh air is available.

THERMAL GENERATOR

The milli-volt gas log pilot is fitted with a milli-volt generator to provide power for remote activation.
