IGNITION CONTROLS
Piezo ignitor allows ignition of the pilot without the use of matches or batteries.
Millivolt control has four (4) positions:
OFF - All gas to the gas logs is shut off at the valve.
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).
PILOT/ODS
The gas log heater is fitted with a specially designed safety pilot (ODS assembly) which senses the amount of oxygen avail-
able 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 millivolt gas log pilot is fitted with a Millivolt (thermopile) generator to provide power for remote activation.
