Chase Enclosure
Opening for vent
When choosing to install the ventilation openings from the front or both sides, The top of the ventilation opening cannot be any lower than 0 - 51mm from
4"-4.5"
the top of the chase enclosure for all installations.
Minimum height of enclosure from base of appliance is 2038mm.
(102 mm x 114 mm)
A minimum 1161cm
opening in the enclosure is required to maintain safe operating temperatures. This can be achieved in a number of ways including the
2
examples shown in this manual.
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 plasterboard or other means such as wood, wood studs, etc. to prevent heat from escaping anywhere above /
through the enclosure other than the required grill / ventilation opening.
Internal chase: When installing as an internal chase framing installation ,regardless of where appliance is placed within the home, requires the use of either
plasterboard or other means such as wood, 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 plasterboard, ensure that the plasterboard is butt up tight with no gaps.
b. Wood, 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).
