ADVANCE PLANNING
Downdraft Vent and Cooktop Cutout
The installation of these downdraft vents with ang GE
or Monogram cooktop requires careful consideration.
Before you begin, review the combination cutout
illustrations on page 6.
Countertop Requirements
The countertop must have a deep flat surface to
accommodate the cooktop and the vent. Countertops
with a rolled front edge and backsplash may not provide
the flat surface area required.
Base Cabinet Requirements
Review the installation preparation on Page 6 to ensure
the base cabinet is deep enough to accommodate the
minimum clearance and that the side and back wall
locations allow the vent to be properlg secured. Ensure
no internal structure elements (such as cabinet corner
braces) interfere with the vent or cooktop.
Before gou begin, gou must:
1. Review countertop dimension illustrations to be
sure gou will have enough flat countertop surface.
2. Check to be sure that the total countertop depth
required (including minimum cutout to front edge
depth) allows enough space for a backsplash.
3. Review the cabinet illustration. Check to be sure
the interior cabinet depth will house the cooktop
burner box, the vent and the cutout clearance from
the front.
4. When countertop and cabinet depth present a
problem, review Creative Solutions.
5. Read this book completelg to accuratelg plan the
installation location, clearances and ductwork
requirements.
With careful planning, gou can achieve acustom look
with minimal adjustments.
