Installation, Operation, and Care of WKGHD & WKGHC GAS CONVECTION OVENS KEEP THIS MANUAL FOR FUTURE USE GENERAL Your Convection Oven is produced with quality workmanship and material. Proper installation, usage, and maintenance will result in many years of satisfactory performance. It is suggested that you thoroughly read this entire manual and carefully follow all of the instructions provided.
LOCATION The equipment area must be kept free and clear of combustibles. Maintain clearances from combustible or non-combustible construction for at least 3" (7.6 cm) from the side and 3" (7.6 cm) from the back of the oven. The installation location must allow adequate clearances for servicing and proper operation. The oven must be installed so that the flow of combustion and ventilation air will not be obstructed. Adequate clearance for air openings into the combustion chamber must be provided.
without depending on the connector and the quick-disconnect device or its associated piping to limit appliance movement. Attach the restraining device at the rear of the oven as shown in Fig. 1. If disconnection of the restraint is necessary, turn off the gas supply before disconnection. Reconnect this restraint prior to turning the gas supply on and returning the oven to its installation position. Separate instructions for installing casters to the oven are included with the casters.
Install right side panels on both ovens. Connect the piping between the top oven and bottom oven. Pipe joint compound must be resistant to the action of propane gases. CHIMNEY The manual gas valve at the bottom of the control panel should remain off until all electrical connections are made and the ovens are checked or used. LONG FLUE EXTENSION RIGHT ANGLED FLUE EXTENSION LEVELING Once the oven is in its permanent position, place a carpenter's level on the oven rack.
GAS CONNECTION GAS DATA Model WKGHD, WKGHC INPUT BTU/HR MANIFOLD PRESSURE Natural Propane Natural Propane 25,000 25,000 3.5" w.c. (0.8 kPa) 10" w.c. (2.5 kPa) Gas supply connections and any pipe joint compound must be resistant to the action of propane gases. The oven is provided with a regulator integral to the gas solenoid valve, and requires no regulator external to the device. A gas shutoff valve is supplied with each oven and is located at the bottom of the control panel.
FLUE CONNECTION Ventilation requirements will vary with each installation and must comply with Vapor Removal from Cooking Equipment, NFPA-96 (latest edition) and with local codes. Considerations to be kept in mind include: • Flue connections should never be made directly to the oven. • The oven should be located under a hood which has an adequate connection to an exhaust duct and extends 6" (15 cm) beyond the oven sides.
LIGHTING THE WKGHD OVEN Open the manual valve. Plug in, turn the MASTER switch ON and turn the thermostat to its maximum setting. Both the ON and HEAT lights should be lit.
