Ah a thermocouple. I agree this is not "electrical equipment".
All of the pool heaters I have seen have some sort of blower and they also connect to the pump so they won't fire up if the pump is off. (along with a pressure switch)

And some other gas heaters have flow sensors.

OK, Here is one for you. The above ground pool is ALL Plastic ( what do you bond to?) There is a pool motor (with a ground lug) and there is a propane gas pool heater with a bond lug. (Which should be bonded to the motor and pool) The EC was afraid to just connect the motor to the heater. He was afraid that the electric might leak back to the large propane tank. ( which BTW is connected with a copper pipe!)Plus if there was current leaking from the motor to the propane tank, and someone disconnect the "Empty" propane tank, would it go Boom? Or would it attract voltage to this large metal propane tank sitting on the ground. Any thoughts?

You still bond the deck, rails and any metal in the water path, including the heater which will be bonded to the tank by the gas code I imagine. In 2005 you will be bonding pavers.
All of this gets grounded via the pump and light EGCs
The whole theory of bonding is that there won't be any voltage gradient. That works as good for sparks as it does for shocks.

Greg,
The deck is wood, the whole pool, inculding top and bottoms rails ( according to the EC on site) is plastic. The only metal within 5 feet is the pool motor and the propane pool heater.
What would you do? Bond heater to filter? The state told the EC to do just that, plus the state told the EC to tell HO to install an insulating fitting betwee the propane tank and the pool heater itself. this way no voltage could get back to the propane tank.

The guy who enforces
the gas code owns that tank. If it is not within 5' of the pool and water doesn't go through it, we don't care. If there is nothing else to bond you are done. I think we try to make this too hard sometime.

gfretwell: Thanks for the link! Now it makes sense to me.
