SERVICE
WARNING: THE RANGE AND ITS PARTS ARE HOT.
BE VERY CAREFUL WHEN OPERATING, CLEANING OR SERVICING THE RANGE.
CONTROLS (FIG. 1)
Thermostat Dial — allows operator to regulate oven
temperature from low to 500°F.
Open Top Burner Valve Knob — regulates gas flow to top burners. Flame increases by turning knob counter­clockwise, and decreases by turning knob clockwise.
Griddle Burner Valve Knob — regulates gas flow to griddle burner. Heat increases by turning knob counter­clockwise, and decreases by turning knob clockwise.
LIGHTING AND SHUTTING DOWN PILOTS
NOTE: All adjustment procedures associated with pilot lighting must be performed by a qualified Vulcan-Hart installation or service person.
Oven Pilot
1. Turn main gas supply ON. Remove lower front panel and lift lighting hole cover.
2. Depress the reset button located behind the lower front panel and light with a lit taper (Fig. 2). Continue to hold reset button for 1 minute.
3. If pilot fails to light, turn main gas supply OFF and wait 5 minutes before repeating Steps 1 and 2.
4. After pilot is lit, turn the thermostat dial to the desired setting.
Fig. 1
Fig. 2
Nightly Shutdown: Turn oven thermostat OFF.
Extended Shutdown:
1. Turn oven thermostat OFF.
2. Turn main gas supply OFF.
– 4 –
Open Top Pilots
1. Remove all top section cover plates and griddles.
2. Turn main gas supply ON (all burner valve knobs should be in OFF position).
3. Begin from the left range top side. Light each indi­vidual pilot from front to rear across the entire range top section.
NOTE: When lighting broiler/griddle section, the pilot is tubular in shape.
4. If any pilot fails to light or extinguishes, ensure that the burner knob is in the OFF position. Wait 5 minutes, then relight.
5. After all pilots are lit, ensure that all burners are operational. To ignite burners, turn the burner valve knobs fully ON, starting from left to right.
6. Turn burners OFF and reassemble top sections.
Nightly Shutdown: Turn burner valve knobs OFF.
Extended Shutdown:
1. Turn burner valve knobs OFF.
2. Turn main gas supply OFF.
Broiler/Griddle Pilot
The broiler/griddle sections are operated by the same burners.
PILOT ADJUSTMENTS
Burner Adjustment
The effiency of the range depends on a rather delicate balance between the supply of air and volume of gas so that complete combustion is achieved. Whenever this balance is disturbed, poor operating characteristics and excessive gas consumption occurs.
Air Supply
Air supply is controlled by an air shutter on the front of the burner. Increase the air shutter openings until the flame on the burner begins to "lift". Then close air shutter slightly and lock in place. A yellow streaming flame is an indication of insufficient air. This condition can be corrected by increasing the air shutter opening.
Main Burner
Econoline Ranges are equipped with pressure regula­tors and fixed orifices which have beed adjusted at the factory and no further adjustment should be required.
Top Burner
Turn one top burner on to remove air from the line. Turn burner off when gas begins to flow. Light top pilots and, if necessary, adjust by rotating adjusting screw clockwise to decrease flame; counterclockwise to increase flame.
Broiler-Griddle or Convectional Griddle
Adjust burner as sharp as possible without flash back.
1. Turn main gass supply ON.
2. Remove grid pan assembly, and using a taper, light the pilot from the underside of the griddle where the grid pan assembly was removed.
3. If pilot fails to light, turn main gas supply OFF. Wait 5 minutes and repeat steps 1 and 2.
Nightly Shutdown: Turn burner valve knobs OFF.
Extended Shutdown:
1. Turn burner valve knobs OFF.
2. Turn main gas supply OFF.
Oven and Safety Pilot
To check or light oven pilot flame, remove lower panel and swing lighting hole cover to the side (Fig. 3).
1. If pilot is out, turn burner off; then wait 5 minutes before relighting.
2. Depress reset button and hold in for 1 minute after lighting pilot.
3. To shut down, turn main burner OFF and extinguish pilot.
If pilot fails to remain lit, insufficient gas is reaching the pilot. Remove adjusting cap above red button to expose adjusting screw for pilot gas (Fig. 4).

Pilot Burner Adjustment (Grayson Safety Valve Shown)
1. Remove pilot adjusting cap.
2. Adjust pilot key to provide properly sized flame.
3. Replace pilot adjusting cap.

THERMOSTAT (BJWA)
To Adjust By-Pass Flame (Minimum Burner Flame):
When oven reaches the temperature at which the dial is set, the oven control cuts down the flow of gas to the amount required to keep the oven at that temperature. The control must by-pass enough gas to keep the entire burner lit to maintain this minimum flame. The by-pass must be carefully and accurately set as follows (Fig. 5).
1. Light oven burner, then turn dial to highest set tem­perature.
2. After 5 minutes, turn dial clockwise to a point slightly beyond first mark on dial (shown by "X").
3. Remove dial and sleeve.
4. With a screwdriver, turn by-pass adjustor counter­clockwise to increase flame, clockwise to decrease flame, until ther is a flame about 1⁄8" high over entire burner.
5. Replace sleeve and dial, turning dial clockwise until it locks in the OFF position.
Fig. 5

OVEN CONTROL RECALIBRATION
NOTE: Do not recalibrate oven control until the by-pass
flame has been adjusted.
The oven is a precision instrument. It is carefully cali­brated at the factory so that the dial settings match the actual oven temperatures. Field recalibration is seldom necessary and should not be resorted to unless consid­erable experience with cooking results definitely proves the the control is not maintaining the temperatures to which the dial is set.
To check oven temperature when recalibrating, use an appropriate test instrument or thermometer.
BJWA Recalibration
1. Remove dial and push metal insert (Fig. 6).
2. Replace dial, turn to 400 mark, and light oven burner.
3. After burner has been on about 15 minutes, check oven temperature.
