Installation

Initial Startup

The following is a check-list to be completed by qualified personnel prior to turning on the appliance for the first time.

jVerify there are no gas leaks, by checking all gas connections with a soapy water solution. Repair leaks if necessary.

jVerify there are no water leaks to the oven. Re- pair leaks if necessary.

jVerify rack rotation as follows: Open oven doors and turn the power switch to ON. Close the doors and enter bake time of two minutes. Press start. Verify the rack rotates smoothly. Open the doors. Verify the rack stops square to the door opening. If rack does not rotate and fan does not circulate, door switch may be out of adjustment.

With the main burner on, check the following:

jSet the oven temperature to 300_F. Verify that the oven comes up to set temperature.

jSet a steam time of 20 seconds. Verify that the oven water pressure is 15 psi when the water solenoid valve is open. The water pressure gauge is located under the right side panel of the oven. Panel must be removed.

jVerify that the gas inlet pressure is correct. The inlet pressure can be checked at the pres- sure tap located on the gas valve.

jVerify that the manifold pressure is correct. The manifold pressure can be checked at the outlet pressure tap located on the burner gas manifold elbow located on top of the oven.

jIf the above pressure readings are set to the recommended pressure requirements, allow the oven to burn-off for two hours with oven vent opened. If the pressure readings are not set correctly, turn off the oven and readjust ac- cordingly. Then recheck pressure readings.

WARNING

The break in procedure burns off excess oils present in the metals during fabrica- tion. Smoke may be produced. Proper ventilation is required.

ADJUSTMENTS ASSOCIATED WITH INITIAL INSTALLATION

Each oven, and its component parts, have been thoroughly tested and inspected prior to ship- ment. However, it is often necessary to further test or adjust the oven as part of a normal and proper installation. These adjustments are the responsi- bility of the installer, or dealer. Since these adjust- ments are not considered defects in material or workmanship, they are not covered by the Original Equipment Warranty. They include, but are not limited to:

Dcalibration of the thermostat D adjustment of the doors

D burner adjustments D leveling

D testing of gas pressure D tightening of fasteners

D rack rotation stop position

No installation should be considered complete without proper inspection, and if necessary, ad- justment by qualified installation or service per- sonnel.
