50 lb. per hour per compartment. A pressure reducing valve is furnished and set at 10 psig. Additional steam kettles and kettle modules can be interconnected to the steamer. Consult Vulcan-Hart for recommendations. Regenerating (Steam Coil) Generators (Fig’s. 5 & 6) The steam supply to the steam coils must be 15 psi at a minimum flow rate of 125 lb.

Testing The Gas Supply System When test pressures exceed ⁄ generator and its individual shutoff valve must be disconnected from the gas supply piping system. When test pressures are ⁄ psig (3.45 kPa) or less, the generator must be isolated from the gas supply system by closing its individual manual shutoff valve.

START-UP TEST RUN After the appliance is installed and proper service connections have been made, thoroughly test the steam cooker before operation. Gas Powered Steam Generator 1. Open manual gas shutoff valve, and if the appliance has a manual blowdown valve, close it. Open left cabinet door and turn water fill and power switch ON.
Page 21
7. Turn power switch OFF. Amber light will go out. 8. Blow down boiler (see BLOW DOWN BOILER in this manual). Direct Steam Powered Cooker 1. Set both timer knobs to “0”. compartment doors and observe that no steam has entered cooking compartments.
OPERATION WARNING: THE STEAMER AND ITS PARTS ARE HOT. USE CARE WHEN OPERATING, CLEANING OR SERVICING THE STEAMER. COMPARTMENTS CONTAIN LIVE STEAM. STAY CLEAR WHILE OPENING EACH DOOR. CONTROLS — CABINET BASE GENERATOR (Fig. 13) Handhole Cover Assembly — when unbolted and removed, allows internal examination and cleaning of boiler if required.
Page 23
Boiler Blowdown Valve — plumbed to the drain pipe of the boiler, and when specified as automatic, will be a solenoid (electrically operated) valve which will close to assist in maintaining proper water level in the boiler and open whenever the steamer is turned off to blow down sediment and scalant that may be lodged in the chamber of the boiler.
Page 24
CONTROLS — COMPARTMENT (Fig. 14) The upper section of the steamer consists of two cooking compartments. Each compartment functions independently with its own controls, and is a separated, sealed steam chamber during the cooking operation. Gasket Plate Screw (Not Shown) — a stainless steel screw on the gasket plate immediately adjacent to each corner of the gasket allows adjustment of the gasket if necessary.
Page 25
Shutdown 1. Turn the boiler power switch to the OFF position to extinguish the pilot light. 2. To make the pilot light and main burners inoperable, turn the gas combination control valve clockwise until it stops (OFF position). 3. To completely shut off pilot light and main burners, close the main gas valve.
The correct water level is a point one-half of the height of the glass. FLUE (GAS BASE GENERATOR ONLY) Annually check the flue when cool to be sure it is free of obstructions. Contact your Vulcan-Hart service representative for any other maintenance required.
COOKING CHART The following table lists suggested cooking times and weights. These times, which will vary depending on initial product temperature, size, shape, etc., are approximate and should be adjusted to suit your operation. PRODUCTS TO BE COOKED IN SOLID PANS PRODUCT Eggs, Scrambled Rice, Long Grain (Cover with 4 cups water/lb.)

Local water conditions may cause excessive boiler scale build-up and cause the generator and compartment controls not to work. Proper periodic service must be performed as outlined in the operating and service instructions. It may also be necessary to install a water conditioner on the generator water feed.
Page 35
With the probe wire removed, check the probes and contactors in the following manner: 1. With an ohmmeter, check the probe at wire connection and shell. There should be no resistance present when the boiler is empty. If resistance is present, remove and clean the probes.

On electric boilers, the high limit thermostat is located behind the contactor box cover. On electric boilers with two heating elements, the thermostat is connected to one of the heating element lugs. On electric boilers with four heating elements, the thermostat is located between the center pair of elements at the top of the elements.
Page 37
Boiler Blowdown Solenoid Valve Does Not Drain If your steamer has an automatic blowdown drain valve, when the blowdown button is depressed, the boiler blowdown valve opens. If your steamer has a manual blowdown drain valve, close it. The water contained in the boiler, being under pressure, should be blown through this valve and be noticeably visible exhausting out the steamer drain.
Page 38
Blow pilot flame out. The reading when the protection valve closes (drop-out point) should be at least 5 MV below first reading. If first reading is correct, but drop- out point is not, problem is in the combination control valve. An open circuit check of the thermocouple should give a meter reading of 30 to 40 MV.
