Preparation
ElectricalRequirements Theunitrequiresa120V AC, 60Hz. 15Abranch circuit. For futureservice, install
the outlet in an easily accessiblelocation.
Mounting Requirements Theunitmustbemounted to thesurrounding housing. See“GeneralInformation”
on page 3for suggestionsfor determininghoodheight.
For bestresults,install the unit as far up in thehousing or hood as possible. This
will improve the function of theappliance.
When calculating theload forthe housingsupportsystem, be sure to include the
weight of the ventilation unit.See “Ventilation UnitWeight” on page 4. forunit
weight by model.
Forproperperformance, thehousing must coverthe entirecookingsurface.

DuctingRecommendations Theunitisfor ductingtothe outside; it cannot be used in conjunction with arecir-
culation unit.
Forthe most efficient air flow exhaust, use astraight duct runorasfew elbows as
possible.
Do notuse flex ducting.Always usemetal ductworkwith adiameter of 6” (150
mm).
COLDWEATHER installationsshould have an additionalbackdraftdamper
installed to minimizebackward cold air flow and anonmetallic thermalbreak to
minimize conductionofoutside temperaturesaspartofthe ductwork. The damper
shouldbeonthe cold air side of the thermal break.The breakshouldbeasclose
as possible to where the ducting enters the heated portionofthe house.
Always installametal ventcover wherethe ductworkexitsthe house.
Make-Up Air:Local building codes mayrequire theuse of make-up airsystems
when usingductedventilation systemsgreater than specifiedCFM of airmove-
ment. Thespecified CFM variesfromlocale to locale. ConsultyourHVACprofes-
