Page 4: Installation Codes And Standards
Casters (Optional) If the cooker is equipped with casters, the gas connector (available from Vulcan-Hart) must comply with the Standard for Connectors of Movable Gas Appliances, ANSI-Z21.69 (latest edition), and a quick- disconnect device that complies with the Standard for Quick-Disconnect Devices for Use With Gas Fuel, ANSI-Z21.41 (latest edition). -

If casters are furnished instead of adjustable legs, the locking swivel casters must be placed in the front. -
Page 6: Electrical Connections
When test pressures are psig (3.45 kPa) or less, the cooker must be isolated from the gas supply piping system by closing its individual shutoff valve. ELECTRICAL CONNECTIONS Make supply connections using insulated copper wire suitable for at least 90°C for the rated load. When initially selecting conduit size, keep in mind the possibility of additional platens being added to the duplex cooker at a later date. -

Page 8: Before First Use
BEFORE FIRST USE The griddle plate is shipped with a protective coating. Remove this coating before cooking with griddle. Clean the griddle with a damp cloth and mild detergent. Rinse with a clean damp cloth and wipe dry. The griddle must be seasoned prior to first use. See the section titled SEASON GRIDDLE SURFACE for seasoning procedure. -
Page 9: Cleaning The Griddle
PREHEAT GRIDDLE CAUTION: Care must be exercised not to overheat the griddle plate by setting the thermostats well above recommended temperatures. Overheating the plate may cause plate warpage, and will carbonize any grease on the plate and cause sticking. 1. Set thermostat to desired griddle temperature. Burners should light. 2. - Page 10 After Each Use Clean the griddle with a flexible spatula or griddle scraper. Take care not to contact the platen surfaces as these can be easily scratched, shortening the life of the coating and promoting sticking. During The Day Flush the hot griddle with water and scrape with griddle scraper to reduce carbonized grease build-up. Follow by a light coating of oil to prevent product sticking.
