IGNITION CONTROLS 

Piezo ignitor allows ignition of the pilot without the use of matches or batteries. 

 

 Milli-Volt and T-Stat 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). 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.
