Check For Gas Leaks; Gas Leakage Checking Using A Liquid; Solution - Thermador Professional PLPKIT Instructions

Check for Gas Leaks

WARNING:
DO NOT use a flame of any kind to check for gas leaks.
WARNING:
Hot Surface Ignitor (HSI) for Grill gets very hot and can cause severe burns.

Gas leakage checking using a liquid

solution

All of the replacement orifices in the PLPKIT, LP conversion
kit, have straight threads (not pipe threads) and do not
require thread sealing compound.
Leak-checking should occur after the orifice conversion is
complete, and before the burner is reassembled and
tested.
• Make sure that all of the LP orifices have been
tightened and that all valves and controls are in the
OFF position.
• Turn on electrical and gas supplies.
• Briefly evaluate the threaded connection of each
replaced orifice individually - that is, one orifice at a
time.
• 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.)
• 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. —Avoid extreme heat from
the Grill HSI on models so equipped. See warning
above.—
• 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.
• Repair all gas leaks immediately after their discovery;
this can often be accomplished by re-tightening the
orifice.
• Since considerable torque is sometimes used during
orifice replacement, leak-check other fitting junctions
leading up to the orifice as well.
• Turn off the gas and electrical supplies.
• Reassemble the appliance in preparation for testing
the newly-converted burner systems.
