Your grill is equipped with adjustable door hinges which may
need adjustment if doors become misaligned. The hinges are
made of two pieces which can easily be detached if door
removal is ever necessary for maintenance.
Removal of Grill Doors
In the case where removal of your doors is necessary, detach
the hinge from the mounting plate by pinching the lever on the
back of the hinge piece.
After detaching the bottom hinge, repeat for the top hinge. It will
be necessary to support the door during this process.
Reinstallation of Grill Doors
To reinstall your grill doors, move the door into position while
aligning the hinge mechanism. First, hook the front of the hinge
piece then push the back until you hear a click.
ADJUSTMENT OF GRILL DOORS
Adjustment of Grill Doors
In the case that your grill doors need minor adjustments, the
two screws on the main hinge piece can be adjusted as shown
below.
Depth Adjustment
To adjust the depth of the door, loosen the rear set screw,
adjust the hinge front to back as needed, then retighten the set
screw.
Lateral Adjustment
Turning the front set screw clockwise will close the gap
between the doors. Turning the front set screw counter-
clockwise will create a gap between the doors.
