GENERAL INFORMATION
IMPORTANT MODEL & SERIAL
NUMBER INFORMATION
Th Dir ct Spark Ignition Syst m is us d on
Whirlpool gas rang s produc d, b ginning
January 3, 2000, S rial Cod RK02. Th Mod l
numb r of th s units will b a “-5” v rsion of
th curr nt G-lin gas rang .
Exampl : SF365PEGQ5
This Dir ct Spark Ignition Syst m will only b
availabl on s lf-cl aning gas rang s.
ELECTRICAL REQUIREMENTS
Th supply voltag is critical for prop r op ra-
tion of th Dir ct Spark Ignition (DSI) Syst m.
Th r quir m nts ar 102 to 132 VAC with th
prop r polarity and ground. If th l ctrical sup-
ply is l ss than 102 VAC, sparking will not b
r liabl . If th syst m is ov r 132 VAC, p r-
man nt damag to th DSI can occur.
NOTE TO TECHNICIAN: Im ro er olar-
ity will cause the direct s ark ignition
system to malfunction. Always check for
ro er olarity at the wall outlet before
re lacing arts.
Prop r polarity must also b suppli d. If th
supply polarity is r v rs d, th DSI control will
not b abl to d t ct th pr s nc of a flam .
R v rs polarity will not aff ct th cooktop op-
ration, but th Bak and Broil burn rs will fail
to r main lit.
A prop r ground is also r quir d. Th DSI con-
trol g n rat s a significant amount of l ctri-
cal nois . This nois is minimiz d by clamp-
ing th nois to ground. If a prop r ground is
not conn ct d, th ERC may p riodically dis-
play “PF,” which m ans that a r s t has oc-
curr d in th ERC.
GAS REQUIREMENTS
Gas supply pr ssur should b a minimum of
7˝ wat r column pr ssur for natural gas, and
11˝ wat r column pr ssur for L.P. gas. How-
v r, th gas distribution valv should main-
tain 4˝ wat r column pr ssur for natural gas,
and 10˝ wat r column pr ssur for L.P. gas.

SECTION 1SECTION 1
SECTION 1
THEORY OF OPERATION
The Direct Spark Ignition System contains a
Gas Distribution Valve and a Direct Spark Ig-
nition (DSI) Control that inter aces with the
Electronic Oven Control, and spark electrodes.
This provides the direct spark ignition and gas
distribution or Whirlpool sel -cleaning gas ree-
standing ranges.
A proper ground and the correct polarity is nec-
essary or the DSI control to sense the pres-
INTRODUCTION
ence o a lame. I the polarity is reversed, or
in some cases i there is a poor ground, the
control will appear to operate normally. How-
ever, a ter an oven burner ignites, the spark
will continue to occur at the burner, and the
valve will then shut o a ter 4 seconds. This is
because the DSI control does not recognize
the presence o a lame when one is present
(see “Monitoring System,” on page 9).

Gas Distribution Valve
The gas distribution valve can be converted to
L.P. gas, when necessary. It regulates the dis-
tribution o gas to the cooktop and both oven
burners. The gas distribution valve is non-ser-
viceable.
GAS DISTRIBUTION VALVE
The gas distribution valve is made up o the
ollowing eatures:
• Natural & L.P. gas regulator
• Manual oven shuto valve
• Bake & broil solenoids
• Pressure tap - To measure gas outlet

MANUAL OVEN SHUTOFF VALVE
A manual oven shuto valve is available on
the gas distribution valve to shut o the gas to
the oven burners. This valve will not a ect the
operation o the cooktop burners. When the
lever is down, the gas to the oven burners is
turned o .

BAKE & BROIL SOLENOID-
ACTIVATED PORTS
The bake and broil gas supply ports are opened
and closed by electrically-operated solenoids.
When voltage is received rom the spark
ignition control or the bake or broil unction,
(8-18 VDC), the solenoid or that unction is
activated, and the valve opens to allow gas
low to the burner. The electrical connections
at the valve consist o three terminals, each
one sized di erently to prevent incorrect wir-
ing (see below).
The solenoids require special voltage/current
(8 - 18 VDC) rom the direct spark ignition con-
trol to operate properly. IMPORTANT: Do not
attempt to operate the solenoids ith any
other voltage supply.

b)Install the conversion cap on the gas
distribution valve with the L.P. side ac-
ing up (you will see L.P. stamped inside
the cap, as shown).
L.P. Gas
The range is manu actured to use natural gas.
To convert the range to use L.P. gas, the ol-
lowing steps are per ormed:
1. Turn o the gas and electrical supplies to
the range.
2. Remove the storage drawer rom the
range.
3. Locate the gas distribution valve at the
rear o the range. To convert the gas
distribution valve:
a)Unscrew the conversion cap rom the
gas distribution valve. Note the di er-
ence between the L.P. and natural gas
ends o the cap.
L.P. GAS CONVERSION
4. To convert the bake burner:
a)Open the oven door and remove the
oven racks.
b)Use a 1/2" open-end wrench and turn
the ori ice hood down snug onto the pin
(approximately 2-1/2 turns). DO NOT
OVERTIGHTEN THE ORIFICE. The
burner lame cannot be properly ad-
justed i this conversion is not made.
