Porthole Installation Guide B:
With screw fastening visible on one side

Fix the mounting frame

Position the mounting frame with the fitted plastic sleeves on one side of the cut-out and temporarily fix it with adhesive tape.

Insert the glass pane centrally

Insert the glass pane centrally into the cut-out and loosely clamp it with three to four small wooden blocks. Secure the blocks with a little silicone to prevent them from slipping.

Recommended dimensions for the spacer blocks:

• Width: 10 to 15 mm
• Length: according to the leaf thickness
• Height: approximately half the clearance between glass and cut-out

Screw on the glazing frame

Position the second ring, the glazing frame, on the opposite side. The supplied raised countersunk screws are inserted into the plastic sleeves and screwed to the mounting frame.

Set the gap dimension for the glazing gasket

Half the distance between the glazing frame and the glass pane is set as the gap clearance for the glazing gasket. Suitable glazing spacer blocks are inserted between the glass pane and the mounting frame for this purpose.

Suitable spacer blocks:

• Red: 2 mm
• Green: 3 mm
• Yellow: 4 mm
• Blue: 5 mm

Insert the glazing wedge gasket on the glazing frame

Insert the supplied glazing wedge gasket between the glass pane and the glazing frame. Work evenly and make sure that the gasket sits cleanly in the intended joint.

Insert the wedge gasket on the mounting frame and remove spacer blocks

Now insert the glazing wedge gasket between the glass pane and the mounting frame. The previously inserted glazing spacer blocks are removed again during this process.
