INSTALLATION OF BATCH TYPE OVENS
1.
Note overall dimensions of oven on assembly drawing and check for sufficient
clearances from walls, overhead, etc. (6" minimum from wood construction).
2.
With chalk line or scribe, lay out on floor the outside dimensions of the oven rear walls
and front. See Illustration #2 and body detail.
3.
Working with the above markings add the outside chalk line for the sidewalls. If oven
has panel type floor, set panel floor and omit Steps 4 through 8.
4.
Place sidewall floor channels on floor inside sidewall chalk lines. Sidewall channels are
1/2" shorter than the inside dimension of oven. The same applies to the rear wall
channel. Refer to floor channel drawing.
5.
Place rear wall floor channel on floor with the ends of the two sidewall channels and rear
channel touching. With a tape line, measure diagonally corner to corner of channels
shifting sidewall channels until measurements are equal. Check again for sufficient aisle,
overhead, etc., clearances.
6.
Mark floor through predrilled holes in channels for location of anchor bolts. Three
anchors are required per ten lineal feet.
7.
Scribe across end of floor channels for reference marks and with drill, drill holes for 3/8"
WEJ-ITS provided.
8.
Replace channels over anchors and fasten with 3/8" nuts and washers. Recheck floor
channels for square. Holes in channel are enlarged to allow for errors in drilling concrete
and expansion. Should floor have excessive pitch, level channels by using steel shims
and grout with concrete grout mix to close the gap between the floor and floor channels.
Gaps under floor channels must be sealed to eliminate fresh air leakage which will effect
oven uniformity.
9.
Starting with the rear corner panels, pack bottom void of panels with insulation provided,
and set the two corner panels in place. Square, flash inside, pack outside corner with
insulation, and install outside flashing. See Illustrations #1, #3, #4, #5, #6, #6a, #6b and
#7 for details of insulating and sealing panel joints.
10.
Prepare next wall panel, packing with insulation. Slide panel in place. Each panel joint
lap approximately 1" depending on the type of panel (see body detail print). Illustrations
#3 and #4 show panel engagement and assembly techniques.
11.
Bolt roof angle to wall and corner panels using 1/4" self-drilling sheet metal screws with
flat washer and, in special cases, 3/8" machine bolts and nuts at special roof tee
junctions as noted, and use standard 3/8" flat washer under bolt head. If roof tees are
required, at roof tee areas holes must be drilled on each side of the roof tee support in
panels for fastening roof angles to panels. This will give a more positive hold to the roof
panel. Refer to Illustration #6 for detail.
12. Referring to oven body detail and panel numbers, continue working both ways from first
corner panel (tying together with roof angle) until only the front section remains.
