LEVELING
Ensure that the oven racks are level in the final installed position. If the oven is installed on legs, turn
the adjustable feet in or out to level the oven front-to-back and side-to-side.
ELECTRICAL CONNECTIONS
WARNING: ELECTRICAL AND GROUNDING CONNECTIONS MUST COMPLY WITH THE
APPLICABLE PORTIONS OF THE NATIONAL ELECTRICAL CODE AND/OR OTHER LOCAL
ELECTRICAL CODES.
WARNING: APPLIANCES EQUIPPED WITH FLEXIBLE ELECTRICAL POWER SUPPLY CORD
ARE PROVIDED WITH A THREE-PRONG GROUNDING PLUG. IT IS IMPERATIVE THAT THIS
PLUG 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.

GAS CONNECTIONS
Gas supply connections and any pipe joint compound must be resistant to the action of propane gases.
Location of the gas inlet is at the rear of the oven. Codes require that a gas shutoff valve must be
installed in the gas line ahead of the oven.
Connect gas supply after leveling the oven. The gas supply line must be at least the equivalent of
3
/ 4 " (19mm) iron pipe. Make sure the pipes are clean and free of obstructions, dirt, or pipe joint
compound.
The ovens are equipped with fixed burner orifices which match with installation elevation.
The oven is provided with a regulator integral to the gas solenoid valve and requires no external
regulator.
Natural gas pressure regulators are preset for 3.5" W.C. (Water Column) (0.87 kPa); propane gas
pressure regulators are preset for 10" W.C. (2.49 kPa).
WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS.
USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.
After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.
TESTING THE GAS SUPPLY SYSTEM
When gas supply pressure exceeds 1/2psig (3.45 kPa), the oven and its individual shutoff valve must
be disconnected from the gas supply piping system.
When gas supply pressure is 1/2psig (3.45 kPa) or less, the oven should be isolated from the gas supply
system by closing its individual manual shutoff valve.
ADJUSTMENTS
Air Adjustment
Although main burner air is adjusted before shipment, it should be checked at the time of installation.
Excessive air will cause flames to lift off a burner when cold or may cause flash-back during normal
cycling of oven, particularly when propane gas is used.
Insufficient air will cause flames to burn with a yellow tip and result in carbon accumulation in the flame
chamber and heat exchanger tubes.
Contact your local Vulcan-Hart servicer if required.

— 11 —
VENT SYSTEM
DO NOT obstruct the flow of flue gases from the flue located on the rear of the oven. It is recommended
that the flue gases be ventilated to the outside of the building through a ventilation system installed by
qualified personnel.
Ovens may use an optional down draft diverter flue method. This optional down draft diverter must be
purchased from the oven manufacturer and vented to the outside; otherwise, the installation of any
such devise will void all oven certifications and warranties. When the diverter is supplied, it may be
connected to a Type “B” vent.
From the termination of the flue to the filters of the hood venting system, a minimum clearance of
18" (457mm) must be maintained.
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.
