Checking For Gas Leaks - Thermador PAALTKITGW Installation Instructions Manual

2. With an adjustable wrench, restrain the elbow fitting.
With a 1/2'' offset wrench, unscrew the auxiliary bake
burner orifice.
3. Replace the orifice as indicated in the table.
48'' Pro Grand
Auxiliary oven bake burner only 1.85 mm (185)
NOTE: The replacement bake orifices have straight
threads (not tapered threads) and DO NOT require thread
sealing compound.
4. Before reattaching the auxiliary bake burner mounting
bracket, perform a gas leakage check of the orifice
and associated supply tube fittings per "Gas leak
checking the bake orifice(s)" on page 14.

Checking for gas leaks

⚠
WARNING
DO NOT use a flame of any kind to check for gas leaks.
⚠
CAUTION
DO NOT spray water solution onto exposed electrical
components. If solution does drip onto electrical
components, shut the power off before wiping off the
electronics.
⚠
CAUTION
Ensure that the STAR burner igniter wire terminals do not
touch the chassis metal, or any metal part, to prevent
sparking. Do not touch the igniter wires while the burner is
turned on to avoid being shocked.
Leak testing should occur after the orifices are replaced
and before the appliance is fully reassembled. However,
the doors of the appliance must also be installed and
closed in order to leak check the broil and bake burners.
Leak testing of the appliance shall be conducted
according to the following instructions.

1. Make sure that the orifices have been tightened and
that all valves and controls are in the OFF position.
2. Turn on electric 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, the elbow fitting, and gas tube compression
nut. (A 25% dishwashing liquid to water mixture is
effective for this.) Avoid spraying electrical
components.
