opening in the enclosure is required to maintain safe operating temperatures. This can be achieved in a number of ways including the

IMPORTANT: Exterior wall/Alcove enclosure: When installing into an exterior cavity or alcove enclosure (ceiling, back and sides), regardless of where
appliance is placed within the home, requires the use of either drywall or other means such as plywood, wood studs, etc. to prevent heat from escaping
anywhere above/through the enclosure other than the required grill/ventilation openings.
Internal chase: When installing as an internal chase framing installation, regardless of where appliance is placed within the home, requires the use of
either drywall or other means such as plywood, on the rear wall of the chase to eliminate heat escaping into the rear wall cavity. If the chase is extended
to the ceiling ,the ceiling will also need to be finished in a manner to prevent heat escaping into floor joist/attic space.
One of the following methods must be used to prevent the heat from escaping:
a. If choosing drywall, ensure that the drywall is butt up tight with no gaps.
b. Plywood, wood studs, etc. installed tightly with no gaps.
As this appliance has been designed with all hot air escaping through the chase enclosure ventilation / grill openings only, if hot air is trapped as a result
of the hot air escaping through joints, crevasses, open studs, or other openings within the enclosure above, this will change the clearances within the
enclosure causing the enclosure to overheat. It is vital that all the hot air from within the enclosure exits through the ventilation openings only.
Ensure that the ventilation openings are made as such to prevent debris, objects from falling into the enclosure.
Warning: DO NOT cover or place objects in front of the ventilation opening air outlet(s).
