incoming to the gas appliance pressure regulator
is 34 PSI (13,8 w.c. pr 3,5 kPa).
The minimum gas supply pressure for checking
the regulator setting shall be at least 1" w.c. (249
Pa) above the inlet specified manifold pressure
to the appliance (this operating pressure is 4"
w.c. (1.00 kPa) for Natural Gas and 11" w.c.
(2.75 kPa for LP Gas).
The appliance must be isolated from the gas
supply piping system by closing its individual
manual shutoff valve during any pressure
testing of the gas supply piping system at test
pressures equal to or less than 34 PSI (13,8
w.c. pr 3,5 kPa).
All opening and holes in the wall and floor, back
and under the appliance shall be sealed before
installation of the appliance.
A manual valve shall be installed in an
accessible location in the gas line external to
the appliance for the purpose of turning on or
shutting off gas to the appliance
5
INSTALLATION: LEGS
The ranges must only be used with the legs properly installed.
Before installing the legs, position the appliance near its final location as the
legs are not suitable for moving the appliance over long distances.
Four height-adjustable legs are shipped with the range in the polystyrene
container situated over the appliance.
After unpacking the range, raise it enough
to insert the legs in the appropriate receptacles situated on the lower part of
the appliance. Lower the range gently to keep any undue strain from legs
and mounting hardware. If possible use a pallet or lift jack instead of tilting
the unit.
Adjust leg height to the desired level by twisting the inside portion of the leg
assembly until the proper height is reached. Check with a level device
to ensure the cooktop is perfectly level.
6
INSTALLATION: ANTI-TIP DEVICE
1.) The anti-tip bracket shipped with the range must be properly secured to the rear wall as
shown in the picture below. The height of the bracket from the floor must be determined after
the range legs have been adjusted to the desired height and after the range has been leveled.
Measure the distance from the floor to the bottom of the anti-tip bracket receptacle on the
back of the appliance. Position the two anti-tip brackets on the wall at the desired height plus
1/8" (0.32 cm). The brackets must be placed at 2 - 5/16" (6.0 cm) from each side of the range.
The distance between the two bracket is 25 - 1/4" (64.1 cm). Secure the brackets to the wall
with appropriate hardware. Slide the range against the wall until the brackets are fully inserted
into their receptacles on the back of the range.
Check to see that the Anti-Tip device is installed properly. Grasp the top rear edge of the
range and carefully attempt to tilt it forward. Verify that the Anti-Tip device is engaged.
2.) Or, use the anti-tip chain, and tighten up with fixed screw on the wall, and when the wall
not suitable for installation, the chain shall be fixed to the cabinet structure.

ELECTRICAL REQUIREMENTS
A properly grounded and electrical
receptacle Type NEMA 14-50R should
be installed; refer to ELECTRICAL
CONNECTION section Page 10.
Check all local code requirements.
GAS REQUIREMENTS
An agency-approved, properly-sized
manual shut-off valve should be installed
no higher than 3" (7.6 cm) above the
floor and no less than 2" (5 cm) and no
more than 8" (20.3 cm) from the right
side (facing product).
To connect gas between shut-off valve
and regulator, use agency-approved,
properly sized flexible or rigid pipe.
Check all local code requirements.
COOKING RANGE WIDTH

INSTALLATION ADJACENT TO KITCHEN
CABINETS
This range may be installed directly adjacent to
existing countertop high cabinets (36" or 91.5 cm
from the floor). For the best look, the worktop
should be level with the cabinet countertop. This
can be accomplished by raising the unit using the
adjustment spindles on the legs.
ATTENTION: The range CANNOT be installed
directly adjacent to kitchen walls, tall cabinets, tall
appliances, or other vertical surfaces above 36"
(91.4 cm) high. The minimum side clearance in
such cases is 6" (15.2 cm).
Wall cabinets with minimum side clearance must be
installed 30" above the countertop with countertop
height between 35 1/2" (90.2 cm) and 37 1/4" (94.6
cm). The maximum depth of wall cabinets above
the range shall be 13" (33.0 cm).

INSTALLATION: RANGE HOOD
To eliminate the risk of burns or fire by reaching over heated surface units, cabinet storage
space located above the surface units should be avoided. If cabinet storage is to be provided,
the risk can be reduced by installing a range hood. These hoods have been designed to work
in conjunction with the range and have the same finish for a perfect look.
For maximum performance, the height of the bottom of the hood from the worktop should be
between 30" (76.2 cm) and 36" (91.4 cm). This would typically result in the bottom of the
hood being 61 1/2" (156.2 cm) to 67 1/2" (171.5 cm) above the floor. These measurements
provide for safe and efficient operation of the hood.
Before installation of the exhaust hood, consult local or regional building and installation
codes for additional specific clearance requirements.
Refer to the range hood installation instructions provided by the manufacturer for additional
information.
