COLLECTOR YARD MOUNT

When no sunny roof area is available or for “show”
systems, the collectors can be mounted on the
ground as shown in Figure 19. The piping and
control wiring to the tank should be insulated and
buried. It is important that the length of these
piping runs be minimized.

Notes:
1.

Front edge of collector should be 18” above
ground

2.

Use washers on all bolted wood connections

3.

All pieces must be measured and cut to orient
collector at la 10

0

– consult

trigonometric reference.

4.

Piping to collector may be buried.
