Door Seal Check
It is very important to check the door seal before using this furnace. Door seal integrity is
essential to maintain temperature uniformity and to prevent fumes being released into the
area surrounding the furnace.
To check the door seal:
1. With the furnace power off and the chamber cold, open the door.
2. Insert a strip of paper (a couple of inches wide) between the door insulation and the
chamber opening. Do not position the paper in the corner of the chamber. Close the
door.
3. Slowly pull the paper strip from the outside. You should feel some resistance. If the
paper does not pull out, this area of the door seal may be too tight, causing a gap in
another area of the door seal.
4. Repeat this test at 2" (5.08 cm) intervals around the door. If the door does not seal
properly, a door adjustment must be done. Refer to section “Door Seal Adjustment (if
necessary)” .
Door Seal Adjustment (if necessary)
To adjust the door seal:
1. Door assemblies have hex nuts attaching the insulation frame to the outer door frame.
Loosen the appropriate nuts and move the door insulation frame to improve the door
seal.
2. Recheck the door seal, following the instructions in the section “Door Seal Check” .
3. If a gap is detected only in the center top edge of the door seal, then the top corners of
the sealing surface of the door may be sanded to lessen the center gap.
