GENERAL INFORMATION
1.
Panels are marked with part numbers (example 270832).
A. Part numbers are referenced by item numbers on the body drawings.
2.
Return Duct items numbered 1, 2, 3, etc., indicate the recirculation or return duct which
corresponds to duct items on duct detail assembly drawings. Items are identified with
part numbers.
3.
Supply Duct items numbered 1, 2, 3, etc., indicate the supply duct which also
corresponds with drawings.
Exhaust Duct 1, 2, 3, etc., indicates exhaust duct.
4.
Floor channels are not used at door (front) end of oven. On double end ovens, floor
channels are used on sides only.
5.
Outside of oven panels are not painted unless ordered (refer to assembly drawing).
Attention must be paid to direction of panel joints.
6.
When moving or storing oven parts, place panels on edge. This eliminates crushing of
panels and the desired numbered panel will be accessible without any shuffling.
7.
Roof angles are designed to come to 1/2" of front and rear panels, i.e., roof angles are 1"
shorter than inside dimension of oven.
8.
WEJ-IT anchors require a hole same diameter as the WEJ-IT and full length of
unthreaded part. Be sure wedges are fully seated in wedge pockets before inserting into
hole. Insert WEJ-IT until washer is flat against work surface and tighten nut two to three
full turns.
9.
Self-drilling sheet metal screws are used for fastening all sheet metal components. It is
very important not to over-tighten the screw. The manufacturer recommends using
torque-sensing drive tools which are easily adjustable to provide positive seating without
stripping. Drill motors are not recommended. Tools with brakes are recommended to
minimize the possibility of stripping. The following are guidelines only and the installer
should always begin at a setting less than the guidelines listed below.
Panel Joints 85-95 in.lb. Torque
Double sheet (ie. Roof angles, floor channels): 45-55 in.lb. Torque
Single sheet (ie. Inside flashing, outside flashing): 35-45 in.lb. Torque
10.
Lap joints are used on duct connections. See duct assembly drawing for details.
11.
A. 1/2" bolt requires 9/16" clearance drill and 7/16" body drill for tapping.
B. The new 1/2" Hex washer head, thread forming bolt requires a .469 diameter hole
(15/32" drill).
C. 3/8" bolt requires 7/16" clearance drill and 21/64" body drill for tapping.
D. The new 3/8" Hex washer head, thread forming bolt requires a .345 diameter hole
(11/32" drill).
