6. LIGHTNING PROTECTION AND BONDING



WARNING: HAVE LIGHTNING PROTECTION MEASURES CARRIED

OUT BY PROFESSIONALS.

If there is an existing lightning protection system, the collector

casing, their mounting frames, and the piping must be tied into the

lightning protection measures by professionals.

Collector Casing (Pan)

Drill into each collector from the bottom and use screw-type devices

to tie it into the lightning protection measures. Use two 1/4” (6.3

mm) diameter stainless-steel sheet metal screws for each collector.

The drill holes should be predrilled to a diameter of 3/16” (5 mm).

See Figure 29 for locations of holes.

Piping

Make the piping connection by means of pipe clamps in the

immediate vicinity of the collectors (above the roof). (Note

possibility of corrosion. Use only compatible metals for fastening to

the aluminum collector pans and mounting hardware.)

Mounting Frame

Connect the mounting frame to the lightning protection equipment

separately via screw-type or clamp connections. Connect the

forward and return piping to the building’s equipotential bonding

system (ground) at frequent intervals.

Min. 4 inches

On each collector, drill two 3/16"

diameter holes in the hatched

area and make the connection to

the lightning protection equipment

with two 1/4" diameter stainless

steel sheet metal screws.
