Burner Testing and Adjustment

Checking manifold pressure (if necessary)

Checking the appliance manifold pressure is NOT
REQUIRED for the Propane Gas conversion; however, if
the outlet pressure of the gas regulator or the inlet pressure
to the appliance is suspect, the following procedure can be
used to check the manifold pressure.
• A manifold pressure measurement can be acquired at
one of the star burner orifices, as shown.
• Attach a portable or hand-held manometer, that reads
pressure in inches water column ("WC), using a piece
of PVC or vinyl tubing.
• Turn on the electrical and gas supplies to the cooktop
or range.
• Turn on one of the top burners to HI position. This is
important to acquire a true pressure reading under gas
flow conditions.
• Turn the manual valve for the burner being monitored
to HI position. (Spark ignition noise will be heard
coming from this burner.)
• The manifold pressure reading on the manometer
should be between 9.50 and 10.50"WC for an
appliance regulator converted to LP gas.
• If the manifold pressure reading is below this range,
verify that the regulator has been properly converted
for use with LP gas, and that the inlet pressure to the
appliance is between 11.0 and 14.0"WC.

Checking LP flame characteristics and
burner performance
To observe the burner flames, loosen or remove the
minimum number of components necessary for an un-
obstructed view. It may be necessary to turn off lights or
close window blinds to darken the room for easier viewing
of the flame.
• Test Burner Ignition. Push in the burner control knob
and turn counter-clockwise (CCW) to "HI". The ignitor
electrode and spark module will produce a clicking
sound. Once the air has been purged from the supply
lines, the burner should light within four (4) seconds.
• The LP flames should be stable, with no excessive
noise. The inner cones of the individual flames should
be well defined and distinctly separate from each other.
• Portions of the flame, along the burner, should not
exhibit excessive or continuous indications of "lifting" or
"lazy flame".
• It is normal for slight yellow tipping of the flames to
appear after a few minutes of operation using Propane
