S-TYPE OVEN FRONT AND SWING DOOR INSTALLATION
The following is a narrative describing the steps for assembly and adjustment of standard oven
fronts and swing doors.
Step #
Description
1.
Lay oven front down on a flat level surface and flush out front sections. The oven
fronts generally ship in three pieces. Dependent on oven temperature design a bead
of either Oven Cement or Silver Seal (refer to manual for temperature limitations)
must be applied between the butt joints where the oven fronts join together. Bolt the
oven front pieces together, check to make sure oven front and door opening is square
and flush with each other. Some oven front styles must be welded together at
assembly, in these cases the welds must be ground smooth to eliminate sealing
problems. Refer to oven front detail drawing for oven front style.
2.
Install packing insulation around front side panel pockets. Dependent on oven
temperature design a bead of either Oven Cement or Silver Seal (refer to manual for
temperature limitations) must be applied around the inside perimeter of the front
where roof and side panels lap.
3.
Slide front section in place making sidewall panel lap joints simultaneously, and using
a 3 or 4 foot level or plumb-bob, plumb the oven front and fasten to the sidewall
panels with self drilling screws at the top portion only. See body detail drawings for
particulars.
4.
With a tape line, measure diagonally corner to corner at top of front and square up
accordingly, check door opening in the same fashion. Run additional fasteners in
fastening front to side panels, one at midpoint and one at the bottom.
5.
NOTE: Hinge pin centerlines must fall on a common centerline. If for some reason
there is a variance, shims (provided with field ship) must be added for proper
alignment. Check centers using a plumb-bob.
6.
Hang doors by tilting and sliding door so bottom hinge strap is in bottom hinge butt.
Drive hinge pin halfway into hinge strap. Lift door at handle edge aligning top hinge
and butt. Drive hinge pin in halfway into top hinge. Lever the door up and insert the
hardened thrust washer on the bottom edge of butt between strap and hinge butt.
See illustration #12 in manual. Drive pin through washer into bottom of hinge butt.
Repeat installation of pins and washers on the remaining hinges.
7.
With doors installed, close doors. Look over the door lap contact around perimeter of
door front opening for uniformity. Check door center vertical lap. If the oven front or
doors are not properly aligned and plumb it will be noticeable where the doors meet at
the center lap showing an uneven gap/contact from top to bottom of doors.
8.
If the lower centers of doors do not seat at the center lap, this indicates that one or
possibly both door front posts are out of plumb. To correct this, remove the screws
holding the front to the side panels except for the top two if already installed and shift
door posts until center door lap is closed. A properly plumbed and aligned door and
front assembly will seal on all outside perimeter edges of door opening and center
