Installation Instructions
Access Door RRD with Ceramic Fibers Gasket and Metal Knobs (up to + 200°C)
Apply the self-adhesive template on the duct wall
at the desired position.
Turn the metal knobs till they hit the stops and insert the inner door panel inside the opening at an angle. Then straighten the door, pull it lightly to center it and tighten the metallic knobs.
Binders and adhesives tend to crumble when exposed to temperatures above 200°C. Should that be the case the KF gaskets must be replaced after each opening of the access door.
