Install a manual shut-off valve in the gas line in an easily accessible location

outside  the  cooktop.  Be  sure  you  know  how  and  where  to  shut  off  the  gas

supply to the cooktop. Install the electrical outlet 12” below the countertop.

Electrical supply:

This cooktop features pilotless electric ignition for energy savings and reliabil-
ity. It operates on a 120 volt, 60 Hz power supply. A separate circuit, protected
by a 15 amp time delay fuse or circuit breaker is required.

· A properly-grounded 3-prong receptacle should be located within reach of
the cooktop’s four-foot power cord.

(Please read carefully)

FOR PERSON SAFETY, THIS APPLIANCE MUST BE PROPERLY GROUNDED.

• The power cord of this appliance is equipped with a three-prong (ground-
ing)  plug  which  mates  with  a  standard  three-prong  grounding  wall  recep-
tacle to minimize the possibility of electric shock hazard from this appliance.

• The  customer  should  have  the  wall  receptacle  and  circuit  checked  by  a
qualified  electrician  to  make  sure  the  receptacle  is  properly  grounded  and
has correct polarity.

• Where a standard two-prong wall receptacle is encountered, it is the per-
sonal responsibility and obligation of the customer to have it replaced with a
properly grounded three-prong wall receptacle.

Do  Not,  Under  Any  Circumstances,  Cut  Or  Remove  The  Third  (Ground)
Prong From The Power Cord.

Do not use an extension cord.

POWER SUPPLY LOCATIONS

Gas supply: These cooktops are shipped from the factory set for either natu-
ral gas or LP gas. Check to be sure you have the correct cooktop for the type
of gas being used.

The pressure regulator must be connected in series with the manifold of
the cooktop and must remain in series with the supply line regardless of
type of gas being used.

The natural gas model is designed to operate at 5” water column pres-
sure. A regulator is required at the natural gas source to provide a mini-
mum of 6” water column to the cooktop regulator

The  liquid  propane  model  is  designed  to  operate  at  10”  water  column
pressure. A regulator is required at the LP source to provide a minimum of
11” water column to the cooktop regulator. For ease of installation, and if
local codes permit, the gas supply line into the cooktop should be 1/2” or
3/4” ID flexible metal appliance connector, three to five feet long.

NOTE:

 Purchase new flexible line. DO NOT USE OLD, PREVIOUSLY USED FLEXIBLE 

CONNECTOR.
