Electrical Connections
Electrical Grounding Instructions:
A 15 AMP service must be provided for each oven. For 115
VAC usage, a cord and plug (NEMA #5-15P) is provided but
connection to the electrical service must be electrically
grounded in accordance with local codes, or in the absence
of local codes, with the National electrical code, ANSI/NFPA
70, or the Canadian electrical Code, CSA C22.2, as applicable.
This appliance is equipped with a three-prong (grounding)
plug for your protection against shock hazard and should
be plugged directly into properly grounded three-prong
receptacle. DO NOT CUT OR REMOVE THE GROUNDING
PRONG FROM THIS PLUG.
A wire diagram is affixed to the rear of the unit.
Power Failure
In the event of a power failure, no attempt should be made
to operate this oven.
Ventilation and Air Supply
Proper ventilation is highly important for good operation.
There are only two choices for properly venting an oven:
1) canopy hood style or 2) direct venting. The ideal method
of venting a GAS Convection Oven is through the use of a
properly designed canopy, which should extend 6” (152 mm),
beyond all sides of the appliance and 6’6” (1981 mm) from
the floor.
A strong exhaust fan will create a vacuum in the room. For an
exhaust system vent to work properly, exhaust and make-up
air must be balanced properly. For proper air balance contact
your local H.V.A.C. contractor.
All gas burners and pilots need sufficient air to operate and
large objects should not be placed in front of this oven,
which would obstruct the airflow through the front.
INSTALLATION Continued
Installation of Direct Flue
When the installation of a canopy type exhaust hood is
impossible the oven may be direct vented. Before direct
venting check your local codes on ventilation, in the absence
of local codes, refer to the National Fuel Code NFPA 54, ANSI
Z223.1 (latest revision).
DRAFT DIVERTER
If the unit is to be connected to a direct flue, it is necessary
that draft diverter be installed to insure proper ventilation.
Direct venting, should be positioned on the main top and
fastened with sheet metal screws provided.
DO NOT UNDER SIZE VENT PIPE! This can cause resistance
to flow and impede good venting. We suggest that if a
horizontal run must be used it should rise not less than 1/4”
(6.25mm) for each linear foot of run, and after a total of 180°
of bends you should increase the size of stove pipe by two
(2”) inches. The flue should rise 2’ (60cm) to 3’ (91cm) above
the roof line or 2’ (60mm) to 3’ (91cm) above any portion of a
building within a horizontal distance of 10 (3 meters) feet.

Fuel Gas code Book NFPA 54, ANSI Z223.1,7,5,3:
