OPERATING INSTRUCTIONS
The control system for these models is a millivolt type.
It consists of a gas control valve/variable regulator, a
standing 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. Ac-
cess to this compartment is gained by rotating the
grille up. See Figure 1.
WARNING:
DO NOT CONNECT 240 VAC TO THE
GAS CONTROL VALVE OR CONTROL WIRING SYS-
TEM 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 first 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
first few minutes after each lighting, vapor may condense
and fog the glass and the flames may be blue. After a
few minutes this moisture will disappear and within 15-
30 minutes the flames should become yellow.
Following this initial burn, turn off the fireplace and al-
low 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.
Cleaning the glass after the initial burn will prevent the
film from becoming baked onto the glass. After this ini-
tial 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
expansion 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.
