WARNING!
Panels on this appliance cannot, in any way, be
covered as it may create a fire hazard.
Note:
When installing the GDST60 and the GDFL60
series direct vent appliances, it is important not to cover
or frame in the lower face on the side opposite the control
access panel. These appliances have latches on the
bottom of the glass that must be opened in order to
remove the glass for cleaning. If you cover the lower
face, access to the latches will not be possible. The
access panel on this side of the appliance is fixed in place
with two screws that must be removed to gain access to
the latches. Again, if the non-valve side access panel is
covered with your noncombustible material you will not
be able to remove the glass.
