RACK POSITION AND GAS
SETTING
NOTE: Infrared burner models must use the full gas
setting (knob fully counterclockwise) to achieve the
best burner performance and highest broiler
temperatures. Lower broiler temperatures can be
achieved by using a lower gas setting (knob in the
range just past off but less than fully
counterclockwise). When using a lower gas setting,
the flame should remain lit and be steady across the
entire burner surface.
For information on rack position and gas setting, refer
to F38215 V-Series Heavy Duty range (HDR) Broilers
Operations manual sent with each unit. The manual is
also available online at www.vulcanequipment.com.
