INITIAL START UP
WARNING
BEFORE LIGHTING, USE A SOAP AND WATER SOLUTION TO TEST ALL
JOINTS FOR GAS LEAKS.
Initial Lighting Procedure
Clean the preservative coating from the griddle plate and splashguard. Add a mild
detergent to hot water and wash the griddle plate and splashguard. Rinse with a
damp sponge and dry with a clean rag.
Turn the main gas valve on.
Light the pilot light by turning the control knob on the combination valve counter-
clockwise to the “PILOT” position. Push the control knob in. It will take several
minutes of holding the knob in, to clear the gas line of air during the initial lighting.
When the gas line is clear of air, hold a small flame next to the pilot burner while
you continue pushing the knob in. Release the knob. The pilot light should remain
lit.
If the pilot flame goes out when you release the knob, re-light while pushing the
knob in for another 45 to 60 seconds.
When the pilot continues burning, the pilot generator is hot enough to generate
sufficient voltage to lock in the safety pilot valve.
Turn the combination valve knob to the “ON” position.
Turn on the Jack in the Box® controller, follow the store Operations manual for
calibrating the controller.
Seasoning the Griddle Plate
Turn on the controller.
Observe the burners through the opening at the top of the control panel.
When the burners go OFF, apply a thin coat of high-grade, non-salted vegetable oil
to the griddle surface.
Rub the oil into the griddle surface with the flat side of a spatula or a towel.
Recoat any dry spots that appear then wait two minutes and wipe off any excess oil.
NOTICE During the first few hours of operation you may notice a small amount of
smoke coming off the griddle, and a faint odor from the smoke. This is
normal for a new griddle and will disappear after the first few hours of
use.
