Front Glass Enclosure Panel, Removal
and Installation
WARNING
Do not operate appliance with the
glass front removed, cracked or
broken. Replacement of the glass
should be done by a licensed or
qualifi ed service technician.
WARNING
Do not attempt to substitute the
materials used on this door, or
replace cracked or broken glass
with any materials other than
those provided by the appliance
manufacturer.

The glass door of this appli-
ance must only be replaced as a

manufacturer. Do not attempt to
replace broken, cracked or chipped
glass separately.
WARNING
Do not attempt to touch the front

These are direct-vent appliances. They are
designed to operate only when the front glass
enclosure panel is installed. Generally the front
glass enclosure panel should not be removed
except to gain access to the components within
the fi rebox, and the appliance may only be oper-
ated without the front glass enclosure panel
in place for very brief periods of time during
appliance checkout and adjustment. Note: The
fl ame appearance will be diminished while the
front glass enclosure panel is removed.
During this appliance checkout and adjust-
ment period, a potential safety hazard exists
- EXERCISE EXTREME CAUTION to prevent
the occurrence of any burn injuries from the
exposed fl ames or hot surfaces. Also note, that
while the front glass enclosure panel (or any of
the panels) is removed, the fl ame appearance
will appear to be smaller than normal.

Removing Glass Enclosure Panels
(see Figure 4)
1. Remove the top louver assembly or radiant
panel by pulling it out and off.
2. Open the control compartment access panel.
by actuating the spring-loaded magnetic
catches securing the panel (gently depress the
outer top corners of the louvered or radiant
panel until the catches "pop" the door free,
allowing it to swing out and down to the open
position).
3. Locate the two (2) latches at the top of the
control compartment. To disengage the two
latches from the bottom vee-fl ange of the
glass enclosure panel, reach for the handles
located towards the back of the latches and
pull the handles down toward the front of
the appliance.
4. Swing the bottom of the door out and raise
it slightly to lift the top fl ange of the door
frame away from the appliance.
Installing Glass Enclosure Panels
(see Figure 4 )
1. Visually inspect the gasket on the backside of
the panels. The gasket surface must be clean,
free of irregularities and seated fi rmly.
2. Position the glass enclosure panel in front of
the fi rebox opening at a 45 degree angle and
engage the top fl ange over the lip at the top
of the fi rebox opening. See Figure 4.
3. Swing the glass enclosure panel down and
back. Ensure the gasket seats evenly as the
panel draws shut. Engage the Vee-fl ange at
the bottom of the panel with the latches and
close the latches to secure the panel.
4. Close the bottom control compartment
access panel.
