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 device 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 inches (45 cm) should 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.
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: DISCONNECT THE ELECTRICAL POWER TO THE MACHINE AND FOLLOW
LOCKOUT / TAGOUT PROCEDURES.
WARNING: APPLIANCES EQUIPPED WITH A FLEXIBLE ELECTRIC 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.
DGC and HGC Series ovens with a 120 V/60 Hz/1 PH electrical specification are equipped with a cord
and plug as standard equipment.
A wiring diagram is located on the inside of the control housing.
BURNER 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 Hobart servicer if required.
