In order to expect any protection from direct or in-direct Lightning
strikes, the entire home must have a properly designed and installed
Lightning Protection System. Just tacking a Lightning Rod to the pipe =
won't
give your customer the protection he seeks. All metal items that protrude
from the roof must be bonded into such a system. Air terminals must be
spaced no more than 20' apart on the ridge. Water, gas, electrical and =
phone
systems must all be tied into such a system. Proper surge suppression
devices must be installed also.
     Lightning enters the home space from above (the sky) as we all know, =
but
it also enters from the earth. There's a lot more to Lightning Protection
than most laypeople realize.

I had a question asked by one of our customers that I wasn't sure how to
answer
as yet. I could just research it and give him a more technical answer but =
I
thought I would throw it out to all the experts out there. He is having =
one
of
our direct vent gas units installed by a propane company. He is using GS
vent,
straight up,flashed to a metal roof attached to a metal stove in an
area that is
subject to a lot of storms. What is his risk of a bolt hitting this system
and
destroying his home and ......?Is a lightning rod attached to the vent =
going
to
help? I am sure this must have been brought up before and I wanted to tell
him
what others have done. Any help would be appreciated.
Thanks,
