CLEANING
NEVER CLEAN THE GLASS WHEN THE DOORS ARE HOT. DO NOT USE
AMMONIAORANYAMMONIABASEDGLASSORHOUSEHOLDCLEANER
TO CLEAN THE GLASS OR THE DOOR FRAME. AN AMMONIA BASED
CLEANER WILL DAMAGE THE FINISH.
Remove dirt and grime from the doors using a clean dampened towel
followed by wiping with a dry towel. To remove stubborn stains from the
doors, use a mild soap solution and towel to gently scrub away stain.
Take care not to scratch the glass surface. Do not use abrasive cleaners.
IMPORTANT
These glass doors utilize tempered glass which is designed for use
with high temperatures but can unexpectedly shatter. DO NOT SIT
CLOSE TO THE GLASS.
Tempered glass will break into small particles if it should shatter
unexpectedly. If the glass breaks, particles of extremely hot glass could
be discharged into the surrounding environment, thereby creating a risk
ofpersonal injuryor fire.Observationoftheaboveoperatingprecautions
and instructions will reduce the risk of personal injury or fire.
Extreme temperature changes can cause breakage — do not build a hot
fire and close the doors if the doors are cold.
If the tempered glass pane becomes scratched or chipped, it creates a
weakness in the glass which can cause the glass to break when heated.
Replace the pane of glass by contacting your nearest distributor. For the

WARNING:DO NOT BURNTRASH, CONSTRUCTION SCRAPS,
RAILROAD TIES, OR OTHER HIGHLY-FLAMMABLE MATE-
RIAL IN THE FIREPLACE. INTENSE HEAT CAN CAUSE THE
GLASS TO LOSE STRENGTH AND RESILIENCE WHICH WILL
RESULT IN GLASS BREAKAGE.
ADJUSTMENT FOR DOOR ALIGNMENT
The doors are properly adjusted when the top door trim is in a straight,
level line and the gap between the doors and the frame is even at the top
and bottom. The doors can be adjusted by changing the location of the
door inside the frame. The door may need adjustment for several
reasons. One would be that the doors do not fully close because they hit
in the center of frame. Another would be that there is a noticeable gap
in the center between the closed doors.
If doors appear to close in correct position but do not latch (both doors
do not stay closed), then there is a misalignment between the doors and
the Center Wedge Clip. The Center Wedge Clip is located in the center
ofthebottomTrack. In order to stay closed,theleftandright doors must
meet in the Middle of the Center Wedge Clip.
To adjust doors, first loosen, but DO NOT remove the Phillips Screw that
holds the Retainer Clip to the frame. Move door to desired position then
tighten screw. Repeat procedure for other Retainer Clips as needed.
Operate doors to check alignment and repeat procedure if necessary.
