2.0 OPERATING INSTRUCTIONS

WARNING
HOT SURFACES!
Glass and other surfaces are hot during
operation AND cool down.
Hot glass will cause burns.
• DO NOT touch glass until it is cooled
• NEVER allow children to touch glass
• Keep children away
• CAREFULLY SUPERVISE children in same room as
fi replace.
• Alert children and adults to hazards of high temperatures.
High temperatures may ignite clothing or other
fl ammable materials.
• Keep clothing, furniture, draperies and other fl ammable
materials away.
This appliance has been supplied with an integral barrier
to prevent direct contact with the fi xed glass panel. DO
NOT operate the appliance with the barrier removed.
The control system for these models is a millivolt type. It
consists of a gas control valve/variable regulator, a stand-
ing pilot assembly, a thermopile, a piezo ignitor, and an
ON/OFF rocker switch. The controls are located in the
lower compartment behind the lower grille. Access to
this compartment is gained by rotating the grille up. See
Figure 1.

WARNING:
GAS CONTROL VALVE OR CONTROL WIRING SYSTEM
OF THIS UNIT.
The gas control system is wired so the thermopile, when
heated with the pilot light, will provide approximately 350
to 500 millivolts. This activates the gas control valve. See
Figure 11 for appliance wiring diagram.
When lit for the fi rst time, the appliance will emit a slight
odor for an hour or two. This is due to paint and lubricants
used in the manufacturing process. Additionally, for the
fi rst few minutes after each lighting, vapor may condense
and fog the glass and the fl ames may be blue. After a
few minutes this moisture will disappear and within 15-30
minutes the fl ames should become yellow.
Following this initial burn, turn off the fi replace and allow
the glass to cool completely. Remove the glass using the
appropriate removal instructions. Clean the glass with any
common household glass cleaner and soft cloth. Clean-
ing the glass after the initial burn will prevent the fi lm from
becoming baked onto the glass. After this initial cleaning it
should only be necessary to clean the glass occasionally as
required. Never scrape or rub glass with any abrasive
materials or cleaners.
The heater may produce a noise, caused from metal ex-
pansion and contraction as it heats up and cools down.
This noise is similar to one that a furnace heat duct may
produce and does not affect the operation or longevity of
the heater.
