10.0 Rainhoods
Due to shipping size constraints, ClimateCraft generally
ships rainhoods loose for field installation. The installation
process differs slightly if there is more than one rainhood
assembly.
10.1 Single Rainhood
1. Install flat black gasket on opening sleeve using
double-sided tape;
2. Apply continuous bead of sealant (Degaseal
2000) to gasket;
3. Align rainhood with opening sleeve;
4. Secure rainhood to opening sleeve with sheet
metal screws provided, assuring continuous seal
between gasket and rainhood.
Figure 10-1.
10.2 Stacked Rainhoods
Prior to installation, stacked rainhoods must be
assembled. This is so the edge of the birdscreen of
an upper hood can be attached to the top of the hood
immediately under. Figure 10-2 shows the birdscreen of
the top rainhood being attached to the lower rainhood.
Figure 10-2.
Once the pre-assembly is completed, the rainhood
assembly can be installed as shown below.
