Checking for Gas Leaks
WARNING
DO NOT use a flame of any kind to check for gas
leaks.
WARNING
Leak-checking should occur after the orifice
conversion is complete, and before the burner is
reassembled and tested.
1. Make sure that all of the LP orifices have been
tightened and that all valves and controls are in the
OFF position.
2. Turn ON electrical and gas supplies.
3. Spray a generous amount of soap and water
mixture—or other solution designed for checking
gas leaks—on the threaded junction at the base of
the orifice. Avoid spraying electrical devices. (A
25% dishwashing liquid to water mixture is
effective for this.)
4. Briefly turn on the valve or control while blocking
the orifice hole with a soft pencil eraser, your
finger, or something similar. It is normal to hear
spark ignition noise during this process.
5. Monitor the base of the orifice junction to see if
bubbles are forming anywhere around the
threaded connection. Bubbles forming are
indications of gas leaks. The amount and sizes of
the bubbles are indications of the severity of the
leakage.
6. Repair all gas leaks immediately after their
discovery; this can often be accomplished by re-
tightening the orifice.
7. Since considerable torque is sometimes used
during orifice replacement, leak-check other fitting
junctions leading up to the orifice as well.
8. Turn off the gas and electrical supplies.
9. Reassemble the appliance in preparation for
testing the newly-converted burner systems.
Checking manifold pressure
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.
2. Turn on the electrical and gas supplies to the
appliance.
3. Turn one of the cooktop burners to HI position. This is
important to acquire a true pressure reading under
gas flow conditions.
4. Turn the manual valve for the burner being monitored
to HI position. (Spark ignition noise will be heard
coming from this burner.)
5. 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.
Check Flame Characteristics
To observe the burner flames, it may be necessary to turn
off lights or close window blinds to darken the room for
easier viewing of the flame.
1. Test STAR
®
burner ignition. Push in the burner control
knob and turn it to HI. The igniter 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 seconds.
• The flames should be stable, with no excessive
noise. The inner cones of the individual flames
should be defined and separate from each other.
Portions of the flame, along the burner, should not
exhibit excessive or continuous indications of
“lifting” or “lazy flame”.
1. Attach a portable or
hand-held manometer,
that reads pressure in
inches water column
(WC), using a piece of
PVC or vinyl tubing.
