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).
