Vulcan-Hart VHL2, VHX24 Location — Direct Connected Steamers, Direct Steam Connections

CONNECTION OF OTHER STEAM COOKING EQUIPMENT TO AN ELECTRIC OR GAS BOILER

Steam can be supplied to additional steam equipment from the auxiliary steam port on the boiler, or Steam Line Connection (Fig. 1). When additional equipment is added, appliance efficiency will be affected. To be certain that you will be operating at optimum efficiency, contact the Vulcan-Hart sales representative in your area for steam boiler horsepower calculations.

The connection point for the steam line to other equipment is a 3/4" NPT tee (female) fitting (1.9 cm) on the left side of the boiler near the top and towards the rear. Remove the 3/4" NPT pipe plug (Fig. 1) (1.9 cm) and use the piping kit available from Vulcan-Hart.

SEQUENTIAL STARTUP OF OTHER STEAM COOKING EQUIPMENT CONNECTED TO A BOILER

After the boiler is operating and producing steam, start the equipment that is farthest away until it is preheated and up to temperature before starting the next piece of equipment. It is recommended that all kettles be started before any compartment steamers. This will allow the larger equipment or the equipment with greater steam requirements to be properly warmed up before smaller, nearer units which require less steam. This will prevent the system from being overwhelmed by initial demand. For configurations or recommendations, contact your Vulcan-Hart representative.

LOCATION — DIRECT CONNECTED STEAMERS

Position the steamer in its final location.

The recommended clearance for proper operation is 36" (91.4 cm) at the front. The required clearance from combustible or non-combustible construction is 0" at the sides and back. The recommended clearance for service access is 18" (45.7 cm) at the sides and back. Clearances less than 18" may require removal of adjacent equipment during servicing at customer's expense.

An exhaust system should be located directly above the steamer to exhaust steam and heat generated by the steamer.

IMPORTANT: Do not locate the steamer directly over a drain.

DIRECT STEAM CONNECTIONS

Provide dry steam to the inlets. If the steam is heavy with condensate, install a ball float trap before the pressure regulator valve. To ensure rapid heatup of heavy, cold loads, the steam supply line must be sized to provide the following:

1.To maintain steam at a pressure of 10 to 12 psi (68.9 to 82.7 kPa).

2.A minimum flow rate of 40 pounds (18.2 kg) of steam per hour per compartment for model VHX24D.

3.A minimum flow rate of 67 pounds (30.4 kg) of steam per hour per compartment for model VHX24D5.

4.A minimum flow rate of 34 pounds (15.4 kg) of steam per hour per compartment for VHL series steamers.

A pressure-reducing valve is furnished and set at 10 psi (68.9 kPa). Additional steam kettles and kettle modules can be interconnected to the steamer. Consult Vulcan-Hart for recommendations.
