3. Ground mounting often requires longer outside piping runs,
so proper insulation and protection of collector piping essential.
Installers should consider laying pipe runs below grade to avoid
damage and to mark the location of these runs to avoid damage
from digging operations. 5.2.4 30/60° Mounting On A Pitched Roof
Procedures described above for mounting of collectors upon a flat
roof apply to mounting on a pitched (sloped) roof, except for the
following:
1. Use of weights to secure collectors and mounting hardware is
not advisable. Collector mounting frames should be fastened to all
pitched roofs in an appropriate manner.
2. The 30° mounting kits add 30° to an existing roof pitch, as shown
in the table below. Roofs with pitches above 12-in-12 generally
should not use this mounting kit, as the resulting collector tilt angle
will be too steep for almost any location.
Roof Pitch (rise-to-run) Roof Pitch Angle Resulting Collector Tilt Angle w/ 30° Mount Resulting Collector Tilt Angle w/ 60° Mount
