Interesting: The cut sheet on the sprinkler has the following in it: When properly installed, there is a nominal 3/32 inch (2,4 mm) air gap between the lip of the Cover Plate and the ceiling, as shown in Figure 2. This air gap is necessary for proper operation of the sprinkler.
They then go on to seal this gap with the air and dust seal. I was under the impression that the gap was critical for the proper operation of the sprinkler, but this doesn't seem to be the case. This same condition exists for the Reliable. Can someone explain why this gap is not required when the seal is applied, but is required otherwise.
