Description
11. Adjust the roller rests, duplicating the height and angle (approximately 30
°
-45
°
) on
each side of the door.
12.
Lower the door and ensure that the door cams in against the oven front. Verify the
distance from the exterior of the door to the oven front is the same side to side, and
that the bottom seal is lightly engaging the floor.
13.
From the inside of the oven, inspect the outside seal on 500
°
F and 650
°
F ovens, or
the inside breaker seal on 850
°
F designs, on the oven front to verify when the door is
down and sealed as it engages the door and front. Look for light shining through gaps
on 500
°
F and 650
°
F designs. You will need light inside the oven to view the 850
°
F
breaker seal style around the inside perimeter of the door opening to view seal contact
to lift door.
14.
Adjust the outside door seals as required to make a solid fit-up on the oven front for all
temperature designs.
15.
When initially starting the oven verify the fresh air damper is closed and the exhaust
damper is 50% open. The oven must not be over-pressurized.
16.
Run the oven from ambient to its maximum temperature in 200
°
F increments,
inspecting the front and seals for leakage at each step.
17.
For more information on door and front adjustment, refer to "LIFT DOOR
TROUBLESHOOTING INFORMATION" found in the manual.
Caution: If the oven is run in an over-pressurized condition, infiltration of hot air may take place
at the door or at the corner flashing, discoloring the oven and/or warping the door front and door.
