1. INSTALLATION
Immediately after unpacking the oven or warmer, check for possible shipping
damage. If oven or warmer is found to be damaged after unpacking, save the
packaging material and contact the carrier within 15 days of delivery.
WARNING
Prior to installation, test the electrical service to assure that it agrees with the
specifications on the machine data plate located on the right side panel near
the controls.
WARNING
For STG7-P-GAS only : Prior to installation, test the gas supply to assure that
it agrees with the specifications on the machine data plate located on the right
side panel near the controls.
WARNING
Appliances equipped with a flexible electric supply cord are provided with a
three- or four-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.
1.1 LOCATION
The oven may be placed where cooking may be observed to enhance customer
awareness and must be installed on a level surface.
The installation location must allow adequate clearances for servicing and for proper
operation of the front and rear doors.
WARNING
A minimum wall clearance of 10” (254 mm) from any glass, and 4" (102 mm)
from each side panel must be maintained.
WARNING
For STG7-P-GAS only : The oven must be installed so that the flow of
combustion and ventilation air will not be obstructed. Make sure there is an
adequate supply of air in the room to allow for that required for combustion of
gas at the oven burner
Keep the space around the bottom and the ventilation opening in the top of the STG
free of obstacles to guarantee a good air flow in the electrical compartment and
combustion chamber .
WARNING
Make sure that the windows stay out of the reach of children. During the grill
process the windows get hot.

WARNING
Do not store or use gasoline or other flammable vapors or liquids in the
vincinity of this appliance
1.2 LEGS / CASTERS
Each oven and warmer is furnished on 2” (50 mm) legs. Stacked units are provided
with casters.
1.3 SUPPLEMENTAL INSTALLATION INSTRUCTIONS
(For model STG(W) 5 and STG(W) 7 units for fixed wiring and stacked or placed
on bases with casters)
WARNING
Safety standards require that, when this appliance is properly connected to the
electrical power supply using a permanently connection, adequate means be
provided to limit movement of the appliance without depending on or transmitting
stress to the electrical conduit. This means that, as part of the installation, the
base or bottom unit of stacked models must be secured to the building
structure (typically either wall or floor) to limit the movement of the appliance
and, thus, helping to prevent damage to the conduit during cleaning,
maintenance and service operations.
A tether bracket, as shown on the drawing below, is provided with the base or
stacking kit. Based on the routing of the flexible conduit, the bracket must be installed
along with the caster to one corner of the base using the hardware provided. The
remaining open hole in the center of the tether bracket is to be used to secure one
end of the tether (locally supplied chain, cable, etc.). The other end of the tether is to
be secured to an anchoring point in the building structure. Note: Length of tether
must be shorter than the flexible conduit to make sure that during appliance
movement, no stress is transmitted to the conduit.

10
Following installation, check to confirm that, when the appliance is moved to
the limits of the tether in each direction, no stress is transmitted to the electrical
conduit.
For STG7-P-GAS only:If the oven is to be installed with casters, the installation shall
be made with a connector complying to the Standard for Connectors for Movable Gas
Appliances ANSI-Z21.69 (latest edition), and a quick-disconnect device that complies
with the Standard for Disconnect Devices for Use with Gas Fuel, ANSI-Z21.41 (latest
edition).Provide a gas line strain relief to limit the movement of the oven without
depending on the connector and the quick-disconnect device or its associated piping
to limit oven movement.
If it is necessary to disconnect the restraint, first turn off the gas supply.
Reconnect the restraint before turning the gas supply on and returning the
oven to its original installation position.
Following installation, check to confirm that, when the appliance is moved to
the limits of the tether in each direction, no stress is transmitted to the piping of
the gas supply.
Note:
Units may be delivered completely stacked or placed on a base.
