edge, with the top of the door tilted toward the center of the firebox.
Step 2. Swing the lower outer corner of the door over the hole in the 
lower frame of the firebox opening, and insert the lower pivot pin into 
the hole (Figures 6 and 7below).
DO NOT BURN TRASH, CONSTRUCTION SCRAPS, 
RAILROAD TIES, OR OTHER HIGHLY FLAMMABLE

GENERAL OPERATING PRECAUTIONS  
AND INSTRUCTIONS
ALIGNING THE BI-FOLD DOORS
The doors are properly aligned when the top door trim is in a straight, level 
line, and the vertical gap between the doors is even from top to bottom. 
To align the bi-fold doors:
Step 1. Grasp one door handle, and loosen the lower door pivot pin using 
a 3/8" open-end wrench.
Note: The upper door pivot pins can be loosened for adjustment 
purposes; however, it is easier to loosen the lower pins.
Step 2. Slide the door panel on the hinge pin until the gap between the 
upper door trim and upper frame is even. 
Step 3. Retighten the lower door pivot pin.
Step 4. If needed, repeat this procedure for the opposite door.
 Avoid  building  extremely  large  fires,  as  the  tempered  glass  could 
become damaged.
 Use fireplace tools carefully to avoid striking the glass.
 Keep wire mesh screens closed during fireplace use.
 Fireplace flue damper must remain open until fire is completely out.
 Ensure that wood and embers are well within the confines of the grate 
area and well away from the glass doors.
 Keep wire mesh screens closed during fireplace use.
 Keep glass doors closed at night when retiring to minimize the loss of 
heated room air up the vent.
IMPORTANT:  THE  FINISH  OF  THESE  DOORS  MAY  BE  PROTECTED 
WITH A SELF-ADHERING PLASTIC COATING THAT MUST BE REMOVED 
 BEFORE HEAT IS GENERATED BY A FIRE IN THE FIREBOX. TO PREVENT 
MELTING, ENSURE THAT ANY PLASTIC COATING PROTECTING THE 
FINISH OF THESE DOORS IS REMOVED  FOLLOWING INSTALLATION. 
REFER TO THE FIREPLACE INSTALLATION INSTRUCTIONS AND HO-
MEOWNER'S CARE AND OPERATION INSTRUCTIONS FOR DETAILED 
INSTRUCTIONS REGARDING THE MAINTENANCE OF THE FINISH OF 
THESE DOORS.
