6. Screed Work
Check the following before starting the screed work:
l
The water is connected properly,
l
The electricity is connected properly,
l
The floor duct is the correct height and distance from the window,
l
The grille is covered (Caution! Cement destroys the surface of the grille!),
l
The sound insulation (not with raised floors) is installed beneath the floor
duct,
l
There are no sound bridges to the bare concrete, particularly around the
height-adjustment feet.
l
All openings and cut-outs in the floor duct heating are sealed from the
screed using appropriate material.
l
The duct openings and cut-outs should be additionally sealed when using
floating screed or other viscous floor coverings.
Caution: The floor duct must not be pressed together by the screed or floor.
Provide expansion joints if needed.
7. Dimensions/Height Adjustment
Separately packaged roll-up grilles, e.g.
when using installation covers to protect
from dirt, are pre-rolled in the factory.
If the steel spiral springs are stretched,
this may result in the grille appearing
over-long. Unroll and lay out the grille for
a few hours to return it to its original
length. The frame is easier to fit if the
roll-up grille is inserted with an up and
down movement as per the figure
above.
