Gas Griddle Periodic Maintenance (PM) Recommendations (cont.)
AccuTemp Products, Inc.
Igniter Probe Assembly
The igniter probes ignite and sense that the pilot burner is operational. Depending on the kitchen-
cooking environment, geographic location and cleaning solutions used, the ventilation airflow can
deposit airborne material onto the probes, causing the pilot burner to have difficulty lighting or
sensing that it is operational.
Required Material:
•
AccuTemp adaptor part #ATR-FT003
•
Nut-driver/wrench
•
Phillips screwdriver
•
Steel brush,
•
Voltmeter
Tasks:
1) Remove the retaining screws and remove the probe assembly.
2) Brush all probes to remove foreign material.
3) Re-install the probe assembly and verify operation.
4) Check millivolts by grounding black lead of adaptor to the chassis, then inserting the red lead
into socket of the connector containing the orange lead to the flame sensor. Reading should
be above 30 millivolts.
Orifices and Burner Venturi
Pilot and main burner orifices can collect dust and grease over time in any kitchen environment. If
this material blocks the orifices, the griddle will be less efficient and can cause intermittent
operation or complete shutdown.
Depending on the size of your griddle, there are a minimum of 3 and a maximum of 4 orifices that
require inspection and cleaning. Each main burner will have an orifice and each griddle’s pilot
burner will have an orifice.
Required Material:
•
Towel
•
Soap and warm water
•
Stiff wire smaller than the orifice nozzle or orifice drill of the same size
hole.
Tasks:
1) Dampen a towel with the soap and water solution and clean the orifice.
2) Take the stiff wire or orifice drill and insert it into the hole in the center of the orifice and run
it back and forth, making sure all foreign material is removed.
3) Clean the burner venturi opening so that it is free of any collected dust, grease and any
other foreign substances.
