VL SERIES STEAMER - SERVICE PROCEDURES AND ADJUSTMENTS

C.Gas burner ports clogged or obstruction around air shutter. After a period of time, gas burners can accumulate carbon in their ports or become clogged by food and grease debris from kitchen cleaning, restricting performance. To clean burners, remove them from burner box and boil in water for 10 -15 minutes to dislodge clog. Clean-out any remaining debris from the gas ports using a wire brush, scribe or pic type metal instrument. Remove any other foreign objects that appear to be obstructing the gas ports or air shutters.

D.Gas orifice clogged or obstructed around air shutter. It is possible for debris to become lodged in the small gas orifice opening over time. Clean-out the gas orifice using a round metal instrument of the same hole diameter or slightly smaller. Clean as needed. If clogging reappears, the orifice should be removed, cleaned and reinstalled. Remove any other foreign objects that appear to be obstructing the gas orifice or air shutters.

INLET WATER STRAINER

The in-line Y strainer should be located upstream of the fill valve solenoid. Shut off the water supply. Unscrew the cap from the body on the leg of the Y that should be pointing downwards toward the floor. Remove the screen and any foreign particles trapped in the opening. Rinse the screen thoroughly to remove accumulated debris and replace the screen in the valve body. If screen can not be thoroughly cleaned, replace it with a new one. Reinstall the cap and ensure that the Y strainer is positioned with the cap pointing downward to catch debris.

The pressure regulating valve strainer will become clogged if dirty steam lines are connected to direct steam models. Remove the hex nut on the bottom of the pressure regulating valve to clean the strainer and valve seat.

PILOT AND THERMOCOUPLE ASSEMBLY (GAS MODELS)

A.One or more electric heating elements malfunctioning. See “HEATING ELEMENTS”

B.One or more heater contactors not pulling in to power heating elements.

C.If steamer operates under three phase power, then check line for all phases.

D.Heavy scale build up on heating element causes reduced heating.

4.Direct Steam Models

A.Building steam supply pressure low.

B.Cooking compartment steam solenoid valve malfunction.

C.Steam pressure regulator adjusted too low.

D.Clogging in the steam line reduces steam supply.

5.Regenerated (Steam Coil) Steamers

A.Heavy scale build up inside copper steam coil.

B.Building steam supply pressure low

C.Cooking compartment steam solenoid valve malfunction.

WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AT THE MAIN CIRCUIT BOX. PLACE A TAG ON THE CIRCUIT BOX INDICATING THE CIRCUIT IS BEING SERVICED.

WARNING: SHUT OFF THE GAS BEFORE SERVICING THE UNIT.

The pilot thermocouple when heated, supplies a DC millivolt signal to an internal solenoid valve on the gas combination control valve. This solenoid valve is designed to shut off the gas flow to the pilot and main burners in case of a malfunction in the system. When energized by the thermocouple voltage, the valve is held in the open position to permit gas flow. The pilot burner flame is controlled by an adjustable needle valve located under a small cap screw on the combination control valve.

When experiencing pilot outages, visually check pilot flame for the proper contact on thermocouple and the flame color. Also, check to see that excessive air drafts are not interfering with proper heating of the thermocouple by the pilot flame.

The pilot flame should be a steady blue flame that envelopes the thermocouple tip. The flame should be about one inch long with half its length extending beyond the outer edges of the pilot shield. If the pilot flame does not appear to be this length and color, then adjust as necessary. See the diagram below for an example of unsatisfactory pilot flames. Turn clockwise to decrease pilot flame and counterclockwise to increase.
