NATURAL GAS: An external regulator is required to reduce
supply pressure to a maximum of 10
systems operating at higher pressure.
PROPANE/LPG: An external regulator is required to reduce
supply pressure to a maximum of 13" w.c.
Millivolt Ignition Controls
The 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
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.
Rear Orifice
Thermal Generator
The millivolt gas log pilot is fitted with a millivolt (thermopile)
#46
generator to provide power for remote activation.

C. High Altitude Installations
2.5mm
NOTICE: If the heating value of the gas has been reduced,
these rules do not apply. Check with your local gas utility
#53
or authorities having jurisdiction.
When installing above 4500 feet elevation: Reduce input
rate 4% for each 1000 feet above 4500 feet.
Check with your local gas utility to determine proper
orifice size.
D. Non-Combustible Materials Specification
Material which will not ignite and burn. Such materials are
those consisting entirely of steel, iron, brick, tile, concrete,
slate, glass or plasters, or any combination thereof.
Materials that are reported as passing ASTM E 136,
Standard Test Method for Behavior of Materials in
a Vertical Tube Furnace at 750 ºC shall be considered
non-combustible materials.
