Installation, Operation and Care of VL SERIES GAS, ELECTRIC, DIRECT STEAM OR REGENERATIVE FOOD STEAMERS SAVE THESE INSTRUCTIONS GENERAL Vulcan-Hart suggests that you thoroughly read this entire manual and carefully follow all of the instructions provided. Your Vulcan Model VL Food Steamer is produced with quality workmanship and material. Its boiler is fully automatic with the heat input controlled by preset pressure switches. A solenoid valve feeds makeup water as needed.
For Gas Appliances Only Keep the food steamer free and clear from all combustible substances. Minimum clearance from combustible and noncombustible construction is 6" (15 cm) at the rear and 6" (15 cm) at each side. Do not obstruct the air flow into and around the food steamer. This air flow is necessary for proper combustion of gases and for ventilation of the food steamer.
Fig. 2 LEVELING AND ANCHORING Using a spirit level, adjust the feet to level the steamer left to right and front to back. Steamers should be elevated on the right side just enough (about 1/16" to 1/8") to give proper drainage. To do this, rotate the rear leg adjusting nut 1 to 1 1/2 turns clockwise after leveling. (Check by pouring a little water in the compartment; all the water should drain.) The rear feet have holes in the flanges for anchor bolts.
PLUMBING CONNECTIONS (Figures 3 through 7) WARNING: PLUMBING CONNECTIONS MUST COMPLY WITH APPLICABLE SANITARY, SAFETY AND PLUMBING CODES. Water Supply Connection The water filter, provided, must be installed in the water supply line going to the filtered water inlet or your steamer warranty may be voided. For incoming water supply line pressures, refer to the water filter manual shipped with the water filter. Follow the recommendations contained in it. Water pressure to the steamer should be 20 to 60 psi.
GAS CONNECTIONS (Fig. 3) CAUTION: All gas supply connections and any pipe joint compound used must be resistant to the action of liquefied petroleum gases. Codes require that a gas shutoff valve be installed in the gas line ahead of the steamer. Connect the gas supply line to the gas valve on the steamer. Make sure the pipes are clean and free of obstructions, dirt and piping compound.
FLUE CONNECTIONS DO NOT obstruct the flow of flue gases from the flue located on the rear of the steamer. It is recommended that the flue gases be ventilated to the outside of the building through a ventilation system installed by qualified personnel. Information on the construction and installation of ventilating hoods may be obtained from the standard for the Removal of Vapors from Commercial Cooking Equipment, NFPA No.

OPERATION WARNING: THE STEAMER AND ITS PARTS ARE HOT. USE CARE WHEN OPERATING, CLEANING AND SERVICING THE STEAMER. LIGHTING THE PILOT (Gas Steamers) Before lighting the pilot, both the burner and the pilot must have been off for at least 5 minutes. Gas to both the burners and to the pilot is automatically cut off if the pilot flame goes out. Added protection is provided by a pressure switch which cuts the heat off when pressure reaches 6 psi (for 5 psi generator) or 15 psi (for 15 psi generator).
6. The cycling pressure switch will open and close the combination valve, which, in turn, will cycle the main burner. To shut the steamer down: 1. Turn the boiler ON/OFF switch to the OFF position to extinguish the pilot light. 2. Turn the combination valve knob clockwise until it stops to stop pilot light and main burners function. 3. To shut off pilot light and main burners completely, close the gas service valve.
The following chart lists the types of pans to use for various foods: FRESH PRODUCT TYPE PAN Solid 12" x 20" Perforated 12" x 20" 18" x 26" PRODUCT EXAMPLES Dehydrated Fruits and Vegetables. Dried peaches, prunes, apples and apricots. Sliced onions and sliced potatoes. Cereals and Puddings. Cream of wheat, rolled oats, rice. Vegetables—to be cooked in their own liquid. Broccoli, brussels sprouts, peas, cauliflower. Meats and Poultry. To save broth, cook in solid pans. Canned Foods.
STARTING THE STEAM GENERATOR Do not feed water into a heated generator which has run dry. If for any reason the generator runs dry, turn all services (electricity, gas or steam) off and wait until the generator cools to room temperature. Local water conditions may cause excessive boiler scale build-up and cause the boiler and compartment controls to operate incorrectly. (See water quality requirements under Plumbing Connections in this manual.
STEAM COOKING Refer to the Steam Cooking with Vulcan Kettles and Steamers booklet (packed with your steamer) for suggested cooking times of various foods. All cooking times are approximate because size, weight, pan loading and product quality will affect steamer cooking times. Use these suggestions and then adjust your cooking times to your own requirements. 1. Prepare vegetables, fruits, meats, seafood and poultry as you would for steam cooking or cooking in water (clean, separate, cut, remove stems, etc.
4. When the timer reaches zero, the arm automatically moves to the rear, shutting off the steam supply and opening the drain. The compartment will exhaust for about 1 minute; then the continuous buzzer will sound, indicating the end of the cooking cycle. 5. Turn the steamer off by pressing the bottom half of the red switch. Then loosen the door screw handle, allowing moisture to escape. After a few seconds, move the latch paddle to the left and then open the door and remove pans of food.
CLEANING Allow the steamer to cool and clean the compartment at the end of each day, or between cooking cycles if necessary. Using warm soapy water and a cloth or sponge, clean the exposed bead of each door gasket after each day's use. Follow with a warm water rinse to remove all traces of detergent. Then wipe with a soft, dry cloth. This will extend gasket life.
An automatic descaler is provided inside the generator to hold minerals in a suspended state so they can be flushed out. This descaler will be consumed. The rate of consumption depends upon the chemical makeup of the feed water and the average volume of feed water required. A regular monthly check by service personnel is recommended until it is learned from experience what the normal life of the descaler is under your operating conditions.
MAINTENANCE WARNING: THE STEAMER AND ITS PARTS ARE HOT. USE CARE WHEN OPERATING, CLEANING AND SERVICING THE STEAMER. WARNING: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AND FOLLOW LOCKOUT / TAGOUT PROCEDURES. DELIMING Refer to the water filter manual shipped in the box with your steamer. DOOR GASKETS After compartments with new door gaskets have been in service for a few days, tighten the door gasket retainer screws.
