TruVection Gas Convection Ovens Installation Installation NOTICE These installation procedures must be followed by qualified personnel or warranty will be void. Local codes regarding installation vary greatly from one area to another. The National Fire Protection Association, Inc. states in its NFPA 96 latest edition that local codes are the “authority having jurisdiction” when it comes to installation requirements for equipment. - Page 10 Installation TruVection Gas Convection Ovens Step 2a: Installation of Legs on Single-Deck Ovens 1. Raise oven sufficiently to allow clearance for the legs to be attached. Use of a lift truck or other mechanical lifting means is recommended. For safety, “shore up” and support the oven with an adequate blocking arrangement strong enough to support the load.
- Page 11 TruVection Gas Convection Ovens Installation Step 2b: Installation of Legs on Double-Deck or Triple-Deck Ovens Double-deck (or triple-deck) ovens can be shipped either already bolted together, or as two (or three) separate ovens to be bolted together after delivery. In either case, the oven that is (or will be) the bottom oven will have leg pads already bolted to the bottom corners of the oven.

TruVection Gas Convection Ovens Cooking Hints Cooking Hints In a standard (non-convection) oven, the air is relatively still and an insulating layer of moisture surrounds the cooking food product. In a convection oven, the fan-blown circulating air strips away this insulating layer allowing the heat to penetrate faster for quicker baking and roasting. - Page 24 Cooking Hints TruVection Gas Convection Ovens Cooking Problems and Solutions If… then… Cakes are dark on the sides and not done in the center… lower oven temperature.

Warranty will be void and the manufacturer is relieved of all liability if service work is performed by other than a qualified technician, or if other than genuine Southbend replacement parts are installed. When any difficulty arises it is always a good idea to check that the oven has been connected to the type of voltage for which it was manufactured. - Page 32 Troubleshooting TruVection Gas Convection Ovens Symptom Possible Cause Check or Replace Ignitor does not glow red. No power to ignitor. Check that voltage from ignitor module to ignitor is 24V. Ignitor draws approximately 3.35 amps at start as it heats up resistance goes down. Gas valve opens approximately 1.8 amps.
