SERVICING

Many factors affect the serviceability of equipment . In the 

chain griddle, there are more components to service than in 

older models . The new griddle is a compact design . Access 

to the temperature control circuitry and ignition units is 

easy . Service techniques for the thermocouple will vary 

depending on the model type .

They unit is available with a 6” (15mm) leg which means 

that under the griddle plate there is only 6” (15mm) of 

working room . To replace a thermocouple it is difficult to 

lift the griddle plate, firmly secured to the support frame . To 

replace a thermocouple requires bottom access because the 

plate is securely fixed (see Figure 3) .

With this introduction to serviceability, and apart from 

the features that make the chain griddle superior to more 

conventional units, many of the servicing tasks are standard; 

the adjustments likewise . The procedures that follow are 

a plain guide to servicing, beginning with adjustments to 

various components .

Have The Right Tools And Instruments

In addition to a service technician’s normal hand tools, for 

servicing this chain griddle we recommend:

1 .  A manometer or other suitable instrument for measuring 

gas pressure

 .  A multimeter

3 .  A digital read-out temperature meter

  A micro-ammeter

CAUTION

 : In this chain griddle we use a J-type 

thermocouple, which requires a meter with a J-type 

connection for checking . Most meters have K-type 

connections .  

Adjustments

Every griddle is inspected and tested before it leaves the 

factory . Adjustments to the unit during installation and 

servicing are the responsibility of the field operator and are 

not considered to be defects in material or workmanship . 

For this reason, adjustments are not covered under the 

equipment warranty .

Pilot Flame Adjustment

A pilot adjustment valve is in the line form each pilot 

combination valve and access to it is behind the lower front 

panel .

1 .  To remove the upper front and lower front panels, refer to 

the installation procedure given earlier . 

 .  To reduce the volume of gas feed to the pilot, turn the 

small screw in the pilot adjusting valve clockwise . 

3 .  To increase the gas feed to the pilot, turn the same screw 

counter-clockwise . 

NOTE

 : Adjust the gas feed to produce a 7/16” (11mm) long 

flame to make sure the flame envelopes the top of the flame 

sensor .

Burner Air

Make sure a burner is warm before adjusting the air shutters 

and follow this procedure .

1 .  First, loosen the screw along the side of the burner near 

the orifice .

 .  A burner flame that gets too much air appears to lift 

above the burner as though separated from it . This 

means the shutter needs throttling back to a more closed 

position .

3 .  A yellow tip on the flame is a sign that the shutter is 

not passing enough air to feed the flame . In this case, it 

necessary to open the shutter .

 .  When the shutter adjustment is complete, tighten the 

screw to lock the shutter setting in the adjusted position .

5 .  Re-close the upper and lower front panels and replace 

the fasteners . 

Removing the Griddle Plate

If it is necessary to remove the griddle top, follow this 

procedure:

1 .  Disconnect the power supply .

 .   Remove the upper control panel .

3 .  Open the lower control panel .

 .  Disconnect all thermocouple sensors and shield bayonet 

adapters . (To reassemble, see the Thermocouple section .)

5 .  Remove the griddle top retaining bolts (both left and 

right) .

6 .  Remove the back flue .

7 .  The griddle top is now easily removed .
