ASSEMBLING THE OVEN TO THE STAND

Unpack the oven and stand.  Position oven on its back, taking care not to scratch or damage it.  The gas pipe
connection protrudes beyond the back; provide for this when the oven is tipped back by resting it on suitable
spacers (2 x 4's, etc.).

Install the two locating studs (included in the stand carton) into the screw plates on the underside of the oven
(see Fig. 2).

Attach each of the four leg assemblies to the bottom of the stand with the 24 bolts and lockwashers (6 per leg).

Mount the oven on top of the stand.

ELECTRICAL CONNECTIONS

WARNING:  THE POWER SUPPLY CORD IS PROVIDED WITH A GROUNDING PLUG.  THE OUTLET TO
WHICH THIS PLUG IS CONNECTED MUST BE PROPERLY GROUNDED.  IF THE RECEPTACLE IS NOT THE
PROPER GROUNDING TYPE, CONTACT AN ELECTRICIAN.

The Model GCO Series Gas Convection Ovens are equipped with a 120 volt / 60 Hz. / 1 phase cord and plug.
