INSTALLATION
Remove packing material and protective film from the oven.
Included inside your oven: Rack
Upper and lower impinger plates
Check for obvious signs of transit damage. If necessary, inform the freight company IMMEDIATELY.
LOCATION AND POSITIONING
Choose a site away from major heat sources. DO NOT position so that hot air is drawn in from fryers, grills, griddles, etc. A heat barrier to the height of the oven must be installed if sited next to a burner, stove or range.
Position the oven with at least the minimum clearances shown
Note: The air intake is located under each side of the oven, even with the clearance specified below it is important that airflow is as cool as possible and not pre­heated by other appliances such as fryers, grills and griddles as this will deteriorate the life and performance of the oven.
WARNING:
Check that the AIR FILTERS are in place prior to operation ( see MAIN FEATURES )
Position the oven with at least the minimum clearances shown
Dimensions in inches
Place the oven on a flat surface that is LEVEL, STRONG and STABLE. Allow a minimum clearance of 2 inches (50mm) to the rear, top and each side to allow air to circulate freely. The air intake is located under each side of the oven, even with the clearance specified above, it is important that airflow is as cool as possible and not pre-heated by other appliances such as fryers, grills or griddles. Allow a minimum of 2 inches (50mm) clearance above the oven for hot air to escape. Allow sufficient clearance, 12 inches (305mm) in front of the oven for the door to open fully. Do not affix labels/stickers to oven other than those applied or approved by the manufacturer.
