COMMON REPAIR PROCEDURES
THERMOCOUPLE REPLACEMENT
1.
On IR equipped ovens, it will be necessary to first remove the Infrared Burner� Disconnect the flex piping to the SV-1 Valve�
Disconnect the wiring harness at the SV-1 Valve� The IR Burner is attached to the oven by two brackets at the bottom plate of
the oven� It is necessary to remove only one other brackets to drop the IR Burner out of the oven� Looking inside of the IR well
you will see that the Thermocouple passes through blocks of insulation before it enters the oven floor� Make sure that the new
Thermocouple passes through the insulation in a similar manner�
2.
Disconnect the Thermocouple wires at the junction box located on the Transformer Plate below the oven� These will be the red and
yellow wires that have the brown sleeve�
3.
Cut the wire off at the base of the bad Thermocouple�
4.
Mark the Thermocouple where it enters the fitting; use this mark as a reference for the depth of the new Thermocouple�
5.
Loosen the retaining nut that secures the Thermocouple to the bottom of the oven�
6.
Slide the Thermocouple out and remove the old fitting from the oven floor�
7.
Using the Compression fitting supplied with the new Thermocouple, slide the new unit in as far as it will go, then check your
reference mark� Make sure the Thermocouple passes through the insulation blocks in the IR well as described in step 1� Hold the
Thermocouple so that it is bottomed out in the hole before tightening the Compression fitting�
8.
Retighten the nut to compress the fitting on to the Thermocouple� Again, make certain the Thermocouple is properly located before
tightening the nut, as it will be impossible to relocate once the nut is tightened�
9.
Attach the wire end of the new Thermocouple to the cut wire of the old Thermocouple and pull the new wiring into the conduit (if
applicable) as the old wire is pulled out at the J-box end� Connect the new Thermocouple leads�
THROTTLE VALVE CLEANING / REPLACEMENT
Caution: Never replace this Valve with any Valve except one supplied by Wood Stone. Doing so will void the ETL listing on
the oven and void the warranty.
To remove the Valve, first turn off the oven.
1.
Remove the front access panel from the oven to allow access to the rear of the Brass Throttle (Flame Height) Control Valve�
2.
If the Valve has a stainless steel handle extension, remove the cotter key holding it in place and set the handle aside�
3.
Remove the Throttle Valve from the pipe Manifold�
4.
Clean any excess grease or debris from the stem orifices and the openings in the Valve body�
5.
Reinstall the Valve and test the oven� The flame should be at maximum height when the Valve is turned fully counter clockwise, and
at its minimum when turned fully clockwise� It should never turn the flame completely off�
NOTE:
If the Valve has become difficult to turn, it should be replaced with a new Valve� Replace only with a Valve supplied by Wood
Stone�
