Removing Glass Enclosure Panels
(see Figure 4 )
Remove the top louver assembly or radiant
panel.
To access the glass door securing latches,
fi rst open the lower control compartment
door (Figure 4 ) by pushing in simultaneously
the left and right top corners of the door.
(The door is hinged at the bottom.) Remove
the bottom compartment door by sliding
the hinge pin, located at the door’s left side,
to the right until it disengages from the left
corner post hole. Pull the door diagonally to
the left, away from the fi replace.
Figure 4
Locate the two (2) latches at the top of the
control compartment and disengage them
from the door frame bottom vee-fl ange,
pulling down on their handles to open them.
REINSTALLING THE GLASS
ENCLOSURE PANEL
Retrieve the glass door. Visually inspect the
gasket on the backside of the frame. Gasket
surface must be clean, free of irregularities
and seated fi rmly.
Position the door in front of the fi rebox
opening with the bottom of the door held
away from the fi replace (Figure 4 ). Hook the
top fl ange of the door frame over the top of
the fi rebox frame.
Let the bottom of the door frame swing
gently in towards the fi replace ensuring that
the gasket seats evenly as the door frame
draws shut. Fasten the two latches located
underneath the fi rebox fl oor to the door's
vee-fl ange. Close both the latches securely.
