We recently put up a put up a gazebo on the deck of our condo unit to provide some much needed shade. The gazebo is 10'x12' and the deck is 12'x16'. The frame is light gauge hollow steel thats powder-coated. The frame slants up from the sides to a small canopy for ventilation. The top is water resistant and flame retardant.
Shortly after putting it up we got some strong thunderstorms and I wondered if this steel frame (comes to a point about 9' high) sitting on a wooden deck would be attractive to lightning? Also I realized that we have a mostly stainless steel grill on casters and attached to a natural gas line that runs out of the basement. The line in some type of heavy rubber or plastic tubing. Don't know if it's flexible metal on the inside. A Gas Co. guy came out and checked and approved the connection, but didn't mention anything about grounding it.
So the question is should either or both be grounded and how should it be done? We do have some tall trees about 15-20' from the deck. Maybe they would be more likely to be struck and i am over-reacting?
