Maintenance
To replace the inner seal loosen, but do not remove, the
two nuts that hold the inner protection plate to the door.
Slide the old rope out from under the plate.
Slide a portion of the new rope under the plate, making
sure to leave enough of the rope exposed to ensure a
good seal. Once the rope is in place, secure the two nuts
to 8 ft/lbs.
The heat exchanger doors should seal tightly with no vis-
ible signs of air leakage. If a leak is detected or if the rope
becomes hard and is no longer flexible, the seal should be
replaced. The same process is used for the upper door.
