NOTE:
An external regulator is required to reduce supply
pressure to a maximum of 10.5" w.c. on Natural Gas sys-
tems operating at higher pressure.
NOTE:
An external regulator is required to reduce supply
pressure to a maximum of 13.0" w.c. for LP systems.
IGNITION CONTROLS
Piezo ignitor allows ignition of the pilot without the
use of matches or batteries.
Manual control has three (3) positions:
OFF
- All gas to the gas logs is shut off at
the valve.
IGN
- Valve position to light/maintain a
standing pilot.
HI/LOW
- Variable position corresponding to
desired flame height.
Milli-Volt 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.
THERMAL GENERATOR
The millivolt gas log pilot is fitted with a milli-volt
(thermopile) generator to provide power for remote
activation.
