Porthole Installation Guide C:
With fastening visible on both sides

Fix the first ring

Position one of the two rings, the mounting frame with sleeve nuts and 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. The blocks are secured with 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 second ring

Insert the second ring, the glazing frame, into the plastic sleeves using the supplied raised countersunk screws and screw it 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 between the glass pane and the mounting frame. Suitable glazing spacer blocks are used for this purpose.

Suitable glazing 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 glazing spacer blocks inserted earlier in step 4 are removed again during this process.
