CABINET CONSIDERATIONS AND COUNTERTOP CUTOUT
Figure 2
Cutout Dimensions are Underlined
Figure 1 –Installed Dimensions (from cooktop edges)
Cooktop to front of countertop – 0" minimum
Dimensions are minimum clearances to combustible materials
Plan the installation of the unit so
that the power cord, gas shut-off
valve and gas pressure regulator are
accessible from the front of cabinet.
If a drawer is installed directly under
the cooktop, its depth (front to
back) should be no greater than 15".
Dimension requirements in Figs. 1
& 2 are for combustible surfaces,
When the surface is protected by a
material listed by UL as a Floor
Protector and Wall Shield covered
with not less than No.28 MSG sheet
metal 0.015 inch stainless steel,
0.024 inch aluminum or copper, it
is considered noncombustible and
some dimensions may be reduced.
For a noncombustible surface over
the cooktop, the minimum
clearance is 24" rather than 30".
• Instructions are based on
StandardAmerican cabinets 36"
high x 24" deep with a 25"
countertop.
• Provide approximately a 10
square inch opening in the toe
kick area or other cabinet area
for adequate air inlet to the
cabinet.
NOTICE: All measurements
given have to be precisely followed.
If nonstandard cabinets are used,
make sure they are installed with
minimum dimensions shown in fig.
1 and fig. 2.

1. Seal the Cooktop
Apply the foam tape packaged with the cooktop to underside of
the cooktop along the perimeter before installing. See Fig. 3.
Important: For solid surface material installations such as Surell™
and Corian®, consult with solid surface manufacturer. Apply heat
reflective tape such as Scotch®Aluminum Foil Tape #425 or #427
around the cutout so that it folds over on the top and sides. DO
NOT WRAPTHETAPE UNDERNEATH THE COOKTOP. Be sure
the tape extends beyond the outermost flange of the cooktop.All
corners should be covered with tape. See Fig 3.
2. Attach Brackets to the Cooktop
Attach clamps of the hold-down brackets packaged with the cook-
top to the rough-in box. Use the washer and screws provided. See
Fig. 4.
3. Install the Cooktop
Insert cooktop into the cutout.Adjust hold-down brackets to de-
sired position and tighten screws to rough-in box. Insert adjusting
screw into clamp and secure cooktop to countertop. See Fig. 4.
Important:For solid sur face material installations:Insert a wooden
block between the end of the screw and the bottom of the coun-
tertop. Do not overtighten adjusting screw. See Figure 4.Trim ex-
cess aluminum tape around cooktop flange.
4. Connect Gas Supply
The gas inlet to the unit is located at the right rear of rough-in box.
See Figure 5.After installing a gas shut-off valve in an easily acces-
sible location under the unit (see Figure 6), install the pressure
regulator (supplied) to manifold pipe usingTeflon®tape on threads
of manifold pipe.To prevent possible damage to the gas pressure
regulator, install it after the rough-in box is in its permanent posi-
tion.
CAUTION: Do not attempt any adjustment of the pressure regu-
lator, except conversion to propane.
Connect the gas supply line to the unit pressure regulator using a
1/2" flex gas line connector between wall shut-off valve and pres-
sure regulator. (See complete procedure in Figure 6.)

Secure regulator to cooktop gas inlet using approved
Teflon®tape. Turn to hand tighten plus 1/4 turn, not
exceeding 1 turn for alignment.
Turn on gas at shut-off valve and check supply line con-
nections for leaks using a soap solution. Do not use a
flame of any sort.
Important Notes for Gas Connection:
The appliance and its individual gas shutoff valve must
be disconnected from the gas supply piping system dur-
ing any pressure testing of that system at test pres-
sures in excess of 1/2 psig (3.5kPa).
The appliance must be isolated from the gas supply pip-
ing system by closing its individual manual shut-off valve
during any pressure testing of the gas supply piping sys-
tem at test pressures equal to or less than 1/2 psi
(3.5kPa).
5. Connect Electrical Supply
Before connecting 5-foot supply cord to wall recep-
tacle, make certain that gas shutoff valve and all burner
controls are in OFF position.
6. Install Knobs
Install control knobs by placing indicator line at 12
o'clock position; press down firmly.
30" Models Only
Two center control knobs have a silver ring on the shaft.
7. Final Check
After electrical connection is complete, place each
burner cap in correct sized notched position and check
operation of electric igniters. Check flame characteris-
tics. Flame should be blue with no yellow tip.
For Massachusetts Installations:
1. Shut-off valve must be a “T” handle gas cock.
2. Flexible gas connector must not be longer
than 36 inches.
3. Not approved for installation in a bedroom
or a bathroom unless unit is direct vent.
