9 WARNING
The rear vent trim has 3/16” (5 mm) standoffs to
keep the appliance slightly off of the back wall.
Do not remove or tamper with standoffs due to
potential temperature issues.
10.
Check for proper installation and use of the anti-tip
bracket. Carefully tip the range forward pulling from
the back to ensure that the anti-tip bracket engages
the range leg and prevents tip-over. The range should
not move more than 1” (2.5cm).
Connect Electrical Supply
9 WARNING
Before you plug in an electrical cord or turn on
power supply, make sure all controls are in the OFF
position.
Before connecting the 5 ft (1.5 m) supply cord to a wall
receptacle, make sure that the gas shut-off valve and all
burner controls are in the OFF position.
9 WARNING
ELECTRICAL GROUNDING INSTRUCTIONS
This appliance is equipped with a three-prong
grounding plug to protect you against the risk of
shocks and it should be plugged directly into a
properly grounded receptacle. Do not cut or remove
the grounding prong from this plug.
Burner Cap Placement
Sealed burners
Your new cooktop has sealed gas burners. There are no
burner parts under the cooktop to clean, disassemble or
adjust. Your cooktop has three different burner sizes:
small, large and dual-flame.
9 WARNING
To prevent flare-ups, do not use the cooktop without
all burner caps and all burner grates properly
positioned.
9 WARNING
To prevent burns, do not touch burner caps
orgrates while hot. Turn the cooktop off and allow
the burners to cool.
The burner parts must be correctly positioned for the
cooktop to function properly. If the burner parts are not
correctly positioned, one or more of the following
problems may occur:
Burner flames are too high.
Flames shoot out of burners.
Burners do not ignite.
Burner flames light unevenly.
Burner emits gas odor.
Burner Cap and Burner Base Placement
After electrical connection is complete, place each
burner base on the corresponding location on the
cooktop. One of the three bars on the burner base
should line up with the notch and prevent the base from
rotating. The small hole or cutout near the edge should
also line up with the igniter. Pay special attention to avoid
damaging the igniter during installation of the base. See
Illustration below.
Once each base is located and resting evenly, place
each burner cap on its correct burner base. See
Illustration.
Place burner cap gently on top of base so that the
prongs of the burner base fit snugly into the groove of
the burner cap.
If the maintop is removed by a certified installer (for
example to check electrical or piping connection) the
panhead screws that were removed must be re-installed
to ensure proper functionality of burners.
17
Checking Burner Cap Placement
Check to make sure that there is no gap between the
burner cap and burner base. See illustration below for
correct and incorrect placements of the burner cap.
You may gently try to move the burner cap from side to
side to check if it is properly placed. If properly placed,
the cap will click from side to side as the prongs hit the
groove ridge.
Install Grates
First position the outer grates, followed by the the central
grate. If you only have two grates, the order in which you
position them is not relevant.
Check the Installation
Place each correct-sized burner cap in its seated,
notched position and check the operation of the electric
igniters. Check the flame characteristics. The flame
should be blue with a minimal yellow tip on the outer
cone of the flames.
Checking the flame characteristics
Note: If the flame is completely or mostly yellow, verify
that the regulator is set for the correct fuel. Retest after
adjustment.
Some yellow streaking is normal during the initial start-
up. Allow the appliance to operate for 4–5 minutes and
reevaluate before making adjustments.
Test for Gas Leaks
9 WARNING
RISK OF FIRE
Never check for gas leaks with a flame.
Leak testing is to be conducted by the installer according
to the instructions given in this section.
1.
Turn on gas.
2.
Apply a non-corrosive leak detection fluid. Include all
joints and fittings between the shutoff valve and the
appliance. Include gas fittings and joints in the
appliance if connections may have been disturbed
during installation.
3.
Inspect for leaks. Bubbles appearing around fittings
and connections indicate a leak.
4.
If a leak appears, turn off supply line gas shutoff valve
and tighten connections.
5.
Retest for leaks. Turn gas back on at supply line
shutoff valve and reapply leak detection fluid.
6.
When no bubbles appear, test is complete. Wipe off all
detection fluid residue.
Yellow flames:
Further adjustment is
required.
Yellow tips on outer
cones:
Normal for propane gas
Soft blue flames:
Normal for natural gas
Orange flames:
Can be normal if certain
types of humidifiers are
used in the home. Flames
should return to blue with-
out the humidifier running.
18
Conversion to Propane Gas (LPG)
Always provide adequate gas supply.
This appliance is shipped from the factory for use with
natural gas. Use this kit to convert the appliance for
propane gas use if necessary. Observe the following:
Ensure that the range is converted for use with the
appropriate gas before using it.
This appliance is designed to operate at a pressure of
10" of the water column when used with propane gas.
When checking for proper operation of the regulator, the
inlet pressure must be at least 1" greater than the
operating (manifold) pressure above. When converting
for propane gas use, the pressure supplied to the
regulator must be between 11" and 13" of the water
column.
The pressure regulator that is located in the inlet of the
range manifold must remain in the supply line.
Use a flexible metal appliance connector or rigid pipe to
connect the range to the gas supply. The connector
should have an inner diameter of 1/2” and be 5 ft
(1.5 m) or less in length. (Exception: Maximum connector
length in Massachusetts installations is 3 ft (0.9 m)). In
Canada, the connector must be single-wall metal and not
longer than 6 ft (1.8 m).
Save the orifices removed from the appliance for future
use.
9 CAUTION
The gas supply shall be shut off prior to
disconnecting the electrical power, before
proceeding with the conversion.
