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).
