How many of you out there have your stove grounded to a grounding rod?
It's the my first winter with the 2840 and looking over my owners manuel I see there is a bolt on the tank to ground it. For some reason I can't find it on mine.

Mootsko, I have mine grounded with that ground mentioned in the manual. On mine it is in the rear on the flange where the tank and firebox meet on the right side and it is just a nut on a stud. You may have to move the insulation a little to see the fasteners on the flange.

Ok.  Thanks. I'll give it a little better look. 
Do you got a rod pounded in the ground?

[Crow]

 Yes I put a rod into the ground and used 6 gauge copper wire.

I did the same. 6' ground rod, #6 solid copper wire.

I'm sorry, but what is the reason for grounding the furnace? My electrical lead in cable has a ground wire that is grounded to the furnace.

For a possible  lighting strike!

As I am not an electrician or pretend to be, here is my reason for grounding it this way. The manual with the furnace shows where to ground it and why. IF/WHEN I have a problem with my stove I don't want a missed step with install to be a reason to not get assistance from the factory.

Getting hit by lightning is very unlikely, however having stray voltage for whatever isn't, the separate grounding rod should take care of that, also water and metal combined with stray voltage does some weird things.

If you can't find/don't have a grounding lug on the boiler just install a water pipe ground clamp on one of the supply/return nipples and connect to a ground rod. Inexpensive protection.

I drilled a hole in one leg and grounded it there.

Circulating water will create an energy field.  Static electricity?

The grounding would help disperse this.

Jut an FYI, you should have your unit grounded to your power supply ground wire which would be tied in to your buildings service entrance grounding circuit. If this is done than you can add another ground rod and conductor (#6 copper minimum) to the stove. If the two are not tied together you have the potential to set up a voltage difference between the two grounding circuits which would also be an electrical code violation. There are never any guarantees for lightning strikes but this is what is also required for CSST gas piping systems in a home with a few other stipulations.

Good post schoppy!

if you ground stove to earth and it is grounded through your electric supply and if your stove is hooked to your domestic water supply it will be bonded there as well. here in Ontario your water line must be bonded to your electrical supply and your gas line must be bonded as well
