GAS CONNECTIONS

Gas supply connections and any pipe joint compound must be resistant to the action of propane

gases. The OV310G is an indirect gas-ﬁ red oven, consisting of a heat exchanger with eight independent, U-shaped

tubes, each with a separate in-shot burner rated at 11,875 BTU/hr for a total input of 95,000 BTU/hr.

Prior to lighting, check all joints in the gas supply line for leaks. Use soap and water

solution. Do not use an open ﬂ ame.

TESTING THE GAS SUPPLY SYSTEM

When gas supply pressure exceeds

/2 psig (3.45 kPa), the oven and its individual shutoff valve must be

disconnected from the gas supply piping system. When gas supply pressure is

/2 psig (3.45 kPa) or less, the oven should be isolated from the gas supply

system by closing its individual manual shutoff valve.

VENTILATION

Information on the construction and installation of ventilating hoods may be obtained from the standard for Vapor Removal from Cooking Equipment, NFPA No. 96 (latest edition), available from the National Fire Protection Association, Batterymarch Park, Quincy, MA 02269.

Exhaust Fan Interlock

A connection point (maximum 5-amps) is provided for Indirect V ent (Exhaust Hood) or optional Direct V ent (Draft Hood). It is located behind the right side service panel adjacent to the 120 V power connection. Consult local codes for vent interlock requirements.

Indirect Vent (Under Exhaust Hood) - Standard

Locate the oven under an exhaust hood with adequate overhangs and exhaust rates to completely capture the by-products of combustion discharged from the ﬂ ue. From the termination of the ﬂ ue to the ﬁ lters of the hood venting system, a minimum clearance of 18" (45.7 cm) must be maintained. The hood exhaust fan can be electrically interlocked with the oven.

PLUMBING CONNECTIONS

Water and waste piping and connections shall comply with the International Plumbing Code 2003, International Code Council (ICC), or to the Uniform Plumbing Code 2003, International Association of Plumbing and Mechanical Ofﬁ cials (IAPMO).

DRAIN CONNECTIONS

Connect a

/2" drain line to the 1/2" NPT drain connection located at the rear of the oven. Route the drain

line to a ﬂ oor drain, allowing a minimum 1" air gap between the drain line outlet and ﬂ oor drain. If oven is being installed on an MB300 Prooﬁ ng Cabinet, it is recommended that separate drain lines be

provided. If it is necessary to interconnect the oven and proofer drains, provide a vent opening in the drain line above the oven drain connection location. Adequate drop must be provided such that the oven drain will not ﬂ ood the proofer cabinet.

ELECTRICAL CONNECTIONS

Electrical and grounding connections must comply with the applicable portions of the National Electrical Code and/or other local electrical codes.

Disconnect the electrical power to the machine and follow lockout / tagout procedures.

Appliances equipped with a ﬂ exible electric supply cord are provided with a three-prong grounding plug. This plug must be connected into a properly grounded three-prong receptacle. If the receptacle is not the proper grounding type, contact an electrician. Do not remove the grounding prong from this plug.

The wiring diagram is located behind the side service panel on the right side of the oven.

Do not connect the OV310G gas model to the electrical supply until after gas connections have been made.

The OV310E is an electrically heated oven consisting of six W-shaped elements, each rated at 3.0 kW for a total input of 18.0 kW. The electrical input is shown in the table below.

HEATING CIRCUIT SUPPLY VOLTAGE

Volts Hertz Phase Amps

208 50-60 3 50 240 50-60 3 43 480 50-60 3 22

Both gas and electric ovens require a dedicated 15-amp, 1 10 V 50 Hz or 120 V 60 Hz, single-phase supply with ground, connected at the control circuit terminal block located behind the right side service panel.
