Step 2: Check the flames
1. Turn the burner control knob to HI.
— Once the air has been purged from the supply
lines, the burner should light within four seconds.
2. Verify that the flames are stable, with no excessive
noise.
— The inner cones of the individual flames should be
defined and separate from each other. The flame,
along the burner, should not exhibit excessive or
continuous indications of "lifting" or "lazy flame".
NOTE:
It is normal for slight yellow tipping of the flames to appear
after a few minutes of operation using Propane (LP) Gas.
Orange-colored streaks in the flame are produced from
burning airborne debris; this is normal during initial start up
and should dissipate within a few minutes of operation.
3. Adjust the burner's control valve to SIM to see that the
flame continues to wrap around the burner. Blow out
the flame, or use a quick fan motion from a writing
tablet or piece of cardboard to extinguish the flame.
Observe the burner's ability to reignite and wrap
around (also called "carry-over") the burner within
several seconds. This flame "carry-over" is essential for
proper burner ignition and reignition.
4. Test reignition of the XLO and observe the carry-over
of the small simmer flames as the XLO system cycles
the burners on and off.
5. If the flame performance is not acceptable it may be
necessary to readjust the valve screw for a burner that
does not have sufficient carry-over of the flame.
Proceed to Step 3 for directions on how to turn the
valve screw until carry-over of the flame is acceptable.
