Lennox Hearth CAMBRIA 850 - Manual (Page 7)

Figure 6
The gaskets’ air-tightness can be adjusted us-
ing the adjustment screw located on the slider
stoppers (see Figure 8). Turning the screws
clockwise will shorten the travel of the slider and
increase the pressure on the door side gaskets.
This may lead to the doors being harder to lock,
so a good adjustment must be found between
a good gasket seal and easy door lock (see
Figure 8, balloon #1).
The door lock can also be adjusted. Remove the
front refractory brick and loosen the two screws
in the middle front of the firebox bottom. Push
or pull on the handle of the door lock. Pushing
the handle will tighten the door seal in the center
of the fireplace (see Figure 9).
Door Opening Adjustment
The doors opening angle can be adjusted. This
allows the doors to slide in the fireplace without
interference or friction with the finishing fac-
ing, which could damage the paint. The screws
located under the bottom hinges (Figure 11)
are used as door opening stops. Tightening or
loosening these screws will keep the door handle
from hitting the finishing facing and won’t allow
friction between door gasket and hearth when
the door is fully pushed in the fireplace.
Bearing Maintenance
The doors are assembled on retractable slid-
ers using roller bearings for easy movement.
Cambria fireplace has been designed to ensure
that bearing maintenance is easy. Remove
the decorative facing by unscrewing the four
decorative caps and the four screws holding
the facing. Remove the doors by lifting them up
from the female hinges (see Figure 5). Remove
the slider stoppers (see Figure 8) and take the
slider bearing assembly out of the fireplace.
Unscrew the nuts to change the bearings
(see Figure 10). Original bearing contains no
grease to resist heat. Adding grease or chang-
ing bearings with greased bearing may cause
a malfunction of the slider. Please use Lennox
Hearth Products replacement parts only (see
Page 25 for part numbers).
