3. If pilot fails to light, turn main gas supply OFF. Wait
5 minutes and repeat Steps 1 through 3.
1. Turn main gas supply ON.
2. Wait 30 seconds, and using a taper, light the open
top pilot.
4. Turn one hot top or griddle top burner valve ON to

PILOT BURNER ADJUSTMENTS
NOTE: All pilot adjustments are to be performed only
Pilot Safety Adjustment
by certified Vulcan service representatives.
With control panel cover removed, light the oven pilot as
explained in the oven lighting instructions. If pilot goes
out, increase the pilot safety adjustment until the flame
completely engulfs the safety device sensing bulb. The
safety adjustment screw is located on the safety control
below the red button.
OPEN TOP BURNER PILOT ADJUSTMENTS
TOOLS: Standard screwdriver.
After pilot is lit, turn the open top burner(s) ON. Adjust the
flame if necessary. To adjust, rotate the pilot valve
adjustment screw provided on the unit manifold pipe.
Turn the burner ON; burner flame should appear on the
burner head within a second. Rotate the screw clockwise
to decrease and counterclockwise to increase the flame.
Bypass Flame Adjustment (Oven and
Thermostatically Controlled Griddle)
NOTE: This adjustment must be made at time of appli-
ance installation.
Check the open top burner nozzle relationship. The
burner nozzle should enter approximately 1⁄4" inside the
burner venturi (Fig. 2).
Ignite oven/griddle burner pilot. With oven/griddle cold,
turnthethermostatdialslowlyclockwiseuntilmainburner
gas is heard snapping ON. Remove the dial. With a
screwdriver, turn the bypass adjustment screw (Fig's. 3
& 4) counterclockwise to increase the bypass flame, or
clockwisetodecreaseit,untilflameovertheentireburner
is approximately 1⁄8" high. The bypass adjustment screw
is located to the left-hand side of the thermostat control
for the oven section, and on top of the thermostat control
for the griddle. After adjustment has been made, replace
dial.
Fig. 2
HOT TOP AND GRIDDLE TOP PILOT
ADJUSTMENTS
TOOLS: Standard flat blade screwdriver.
After pilot is lit, adjust the burner flame, if necessary. This
is accomplished by rotating the adjustment screw of the
pilot valve located on the manifold pipe. Turn the burner
ON; burner flame should appear on the burner head
within a second. Rotate adjustment screw clockwise to
decrease and counterclockwise to increase the flame.
OVEN ADJUSTMENTS
TOOLS: Standard flat blade screwdriver.
There are two different adjustments to check for in the
oven section: pilot safety, and bypass.

TEMPERATURE CONTROL RECALIBRATION
STANDARD OVEN TEMPERATURE CONTROL
RECALIBRATION
Field recalibration is seldom necessary and should not
be resorted to unless experience with cooking results
definitely proves that the control is not maintaining the
set temperature. To check oven temperatures when
recalibrating, use a Robertshaw Test Instrument or a
reliable mercury oven thermometer.
Fig. 5
1. Place thermocouple of test instrument or thermom-
eter in the middle of the oven. Close oven door.
CONVECTION OVEN TEMPERATURE CONTROL
RECALIBRATION
2. Light main burner.
1. Place thermocouple of test instrument in middle of
oven. Close oven door.
3. Turn dial to any temperature setting and allow oven
to heat until flame cuts down to bypass. Let cycle
several times.
2. Light the main burner by turning thermostat dial to
any temperature setting.
4. After burner has been on sufficiently long enough to
cut down the bypass flame, check oven temperature.
The control should be recalibrated if your reading is
not with 15° F of the dial setting. If recalibration is
required, proceed as follows:
3. Allow oven to heat until flame cuts off. After several
cycles, check temperature. If the temperature does
not read within 15° F of the dial setting, recalibrate as
follows:
5. Remove dial.
4. Pull dial straight off dial shaft without turning (Fig. 6).
6. With a screwdriver, loosen the two calibration screws
(Fig. 5) until calibration plate moves independently
of the control.
5. Turn screw “A” clockwise to decrease temperature
and counterclockwise to increase temperature (Fig.
6).
7. Turn calibration plate until mark corresponding to test
instrument or thermometer reading is in line with
center of pointer “A” (Fig. 5), and while holding in this
position, tighten calibration screws firmly.
1
NOTE: ⁄4 turn of Screw “A” represents a temperature
shift of 35° F.
8. Replace dial.
9. NOTE: If the above adjustment is prevented by the
two loosened calibration screws being in contact with
theendsofthescrewclearanceslotsinthecalibration
plate, remove the screws, and after turning the cali-
brationplatetotheproperlocation,reassemblescrews
in the other tapped holes designed for them.

CLEANING
THERMOSTATICALLY CONTROLLED GRIDDLE
RECALIBRATION
To clean limiting orifice (Fig. 7), turn gas supply to unit
OFF. Disconnectpilottubingatthepilotburnerbody. The
orifice is then accessible at the body end of the pilot
burner and can be removed for cleaning. Clean spud,
taking care not to enlarge the orifice hole.
Field recalibration is seldom necessary and should not
beresortedtounlesscookingresultsdefinitelyprovethat
griddle surface temperature and thermostat setting do
not agree. To check griddle temperature, use an accu-
rate “surface temperature thermometer” in the following
manner.
1. Locate thermometer in center of griddle from front to
rear: on 17" wide units, use one thermometer and
center from side to side; on 34" wide units, use two
thermometers,one8-1⁄2"fromeachsideofthegriddle.
2. Set thermostat dial to any temperature and allow
griddle to heat thoroughly. When the griddle is com-
pletelyheatedandtheburnerisonbypassgas, check
the thermometer reading against the thermostat
dial setting. If the difference between the readings
exceeds15°F,thethermostatshouldberecalibrated.
Example: With the thermostat dial at 400° F and a
thermometer reading of less than 385° F or more
than 415° F, the thermostat should be recalibrated.

SERVICE INSTRUCTIONS (Fig. 8)
1. If valve fails to open with good pilot flame impinge-
ment, replace valve.
2. Do not remove interrupter valve for field service.
NOTE: Make certain gas line to inlet of control is purged
of air and that gas flow is available at this point.
Recalibration Procedure
Make note of number of degrees thermostat is off.
Remove thermostat dial and loosen calibration screws
(Fig. 9) until plate moves freely. Turn calibration plate the
required number of degrees counterclockwise if the
thermometer reading was higher than the dial setting, or
clockwise if the thermometer reading was lower than the
dial setting. Hold calibration plate in desired position and
tighten plate screws firmly. The number of degrees
between letters on the calibration plate is 50° F.
