Leveling the Oven and Proper Door Operation
It is common when installing the oven for the doors to appear to be hinged improperly. It is especially deceiving when an oven has doors on both ends. The oven must be level for proper door operation. If it is not level, place a shim under one corner of the oven frame. If the leveling improves with the shim, continue adding shims until the doors are level. Shims may be required on more than one door for those ovens with doors on both ends. See Section K for more information on leveling the doors.
2.4
Removing Shipping Supports
Occasionally, temporary supports are built into the oven frame to provide reinforcement during shipping and handling if the oven is shipped assembled. Specifically, ovens with steel plate floors or those ovens without any floors usually have angle iron supports across the bottom of the doorways. After the oven has been located at the place of final installation, these supports should be cut out.
2.5
Securing the Oven
Shipping brackets and floor mounts are attached to the sides of the oven at the base of the frame if the oven is shipped assembled. After the oven has been properly located and leveled, it should be anchored to the floor. If the oven has a steel plate floor, it may be desirable to secure the oven floor to the plant floor. A steel plate floor tends to buckle in ovens of larger sizes and higher operating temperatures. Holes in the steel plate floor can be made by drilling or torch-cutting.

Special Requirements
Most ovens are tested at Col-Met Spray Booths, Inc. prior to shipping. However, for shipping and handling purposes some ovens require final assembly at installation. Height restrictions in shipping and handling sometimes require that burner boxes be built removable and the oven cabin be shipped knocked-down flat. Width and depth restrictions s ometimes require that the oven be built in sections. Occasionally, at the customer’s request, the control panel might be built for remote installation. In these cases, the reassembly requirements are minimal. Each of these scenarios are discussed in detail below. Col-Met Spray Booths, Inc. supervision is available for any or all parts of the installation.
1.1 Burner Box
1. The burner box houses the recirculation fans and the burner. The fan motors and air seals are also generally attached. If the oven has the burner box removed from the oven then the following steps are required for reassembly: Pick up the burner box using overhead means. See Section H for more detailed instructions.
2. Verify that the turning vanes for the fans are secured to the blower housings at the bottom of the burner box.
