THERMOSTAT ADJUSTMENTS

NOTE: These procedures should be performed only by a qualified Vulcan-Hart service representative.

STANDARD OVEN

Although the unit thermostats are factory positioned to their proper setting, it is not unusual for the thermostat to be knocked out of adjustment during shipment. If the oven or griddle heat response seems to be lacking after burner air shutter adjustments have been checked, perform the following adjustments.

NOTE: There are two possible conditions of the thermostat that must be checked: bypass adjustment and temperature calibration.

Bypass Adjustment

TOOLS REQUIRED: Thermometer test instrument (not of bi-metal or mercury type), standard flat blade screwdriver.

WARNING: DO NOT USE BI-METAL OR MERCURY THERMOMETERS WHEN TESTING FOOD EQUIPMENT OR PRODUCTS. CHEMICALS WITHIN THESE INSTRUMENTS MAY BE TOXIC IF EXPOSED TO FOOD.

1.Using a test instrument or thermometer, check the oven or griddle temperature (whichever is in question of heat response) against the thermostat dial setting.

Place the thermocouple of the test instrument on the center of the oven rack. Light the main burner by turning the thermostat to 500°F (260°C).

Allow at least 10 minutes for temperatures to stabilize. Check reading against dial setting.

2.If temperature is out of calibration, allow unit to cool until the oven bottom or griddle plate (whichever is being tested) is cool to the touch. Remove oven bottom or griddle plate to expose burner area (Fig. 16). (Removal of oven bottom is an optional procedure. Burner flame may also be observed through the oven view port.)
