ADVANCE PLANNING
• Refer to “Installation Preparation” for information on appropriate placement
and necessary clearances when planning installation.
• Avoid placing cabinetry directly above cooktop when possible.
• If cabinetry is used above cooking surface:
1. Use cabinets no more than 13” deep.
2. Maintain 30” minimum clearance between cooktop and unprotected
cabinets or exhaust hood directly above the COS-640STX-E; maintain 34"
for the COS-850SLTX-E cooktop.
3. If clearance is less than 30”, protect cabinet bottoms with flame-retardant
millboard at least 1/4”thick, or gypsum board at least 3/16” thick, covered
with 28 gauge sheet steel or .02” thick copper.
4. Clearance between cooktop and protected cabinetry must not be less
than 24”.
5. An exhaust hood that projects at least 5” beyond front of cabinets can
reduce risk of burns caused by reaching over heated surface units.
6. Working areas adjacent to the cooktop should have 18” minimum clearance
between countertop and cabinet bottom.
• A 30” or wider exhaust hood with 350 CFM or greater airflow rating is
recommended for use over the 640STX-E cooktop; 36" or wider for the
COS-850SLTX-E Cooktop.
• Installation must conform with local codes. In the absence of local codes,
the gas cooktop must comply with the National Fuel Gas Code, ANSI Z223.1,
latest edition.
• Gas supply should be located near the opening for this cooktop (see
Preparing the Opening and Gas Connection sections of this manual). The
supply should provide natural gas at 7” of water column pressure (11” of water
column for LP gas) and a maximum of 14” of water column for natural or LP gas.
• The electric spark ignition feature for this model requires a 120V electrical
power supply be located in the immediate vicinity of this cooktop (see
Electrical Connections section of this manual).
INSTALLATION OPTIONS
Cooktop and Single Oven Combination Installation
These cooktops may be installed over a COSMO 30” Oven.
• Consideration must be given to electrical and gas supply locations.
Installation Above Cabinet Drawers
• When installing the cooktop above a base cabinet with drawers, it may be
necessary to use a shorter depth (front to back) drawer to allow clearance for
the gas connection.

DIMENSIONS AND CLEARANCE
• To ensure accuracy, it is best to make a template for the opening.
• Make sure the sides of the opening are parallel and the rear and front cuts
are exactly perpendicular to the sides.
• Make sure the wall coverings, countertop and cabinets around the cooktop
can withstand heat (up to 200°F) generated by the cooktop.
