GARN anode rod locations

[foxt]

I have a WHS-2000, circa 2008, and it is time to replace the anode rods. Unfortunately (for me), I failed to provide access to these when I built the platform over the top of my unit, and I now need to drill through the platform to access the rods. Would anyone be able to give me an approximate location for both rods, referenced from either the manhole (I did provide access to that!), or the front edge of the tank?

I have called / emailed GARN, no response. I also have not found the location marked on any of the drawings I have, or can find, for the unit. I am hoping that: a) the locations are standard, at least on the same models/vintage; b) someone will be able to take a quick measurement on their WHS-2000, or about the same vintage, for me.

The last resort will be to hang upside down in the manhole and attempt to measure from within the tank. If it comes to that, I'll record the measurements here ...

Thanks in advance!

Tom ..Did you ever get an answer on this ? I just came across your posting. We are the Northeast reps for GARN boilers. Very sorry that you had no email response from GARN. They have been in the process of moving their offices and research facility this last month and things have been a little hectic..I'm afraid your email must have fallen through the cracks. I'll have those dimensions for you tomorrow. Also please feel to call me anytime at 207-677-2509.

Thanks Chris. I did not get a response, and have been stalling in hopes of a response ... so thank you!

Here's an attachment w/ measurements taken from my circa 2010 GARN 2000. I was measuring through 4" of foam so it's probably +/- 1/2" . Also..there may be some variation on these fittings exact locations as the location is not critical to the unit's operation. I think I'd use a 4" hole saw and leave some room. I spoke to David Lunde at GARN today and they will have measurements of anode locations in the drawings in the next revision of the manual. They do revisions once or twice a year in response to requests for clarifications of installation details or operation that come to their attention. You can always download the most recent revision from the GARN website.

Thanks Chris! Interesting that the rods are not centered on the manhole, I wonder why not? I will get a chance to drill some holes tomorrow, and will report back as to how it turns out ...

The rods are offset from center line to clear one of the heat exchanger tubes. As I said before these units may have been manufactured with some minor (I hope) variation in anode locations. I hope I'm not steering you too far wrong here Tom..let me know. One more thing..if those rods have been in there a while I suggest spraying some PB Blaster on the threads and letting things sit for a while before you try to remove them. It's also not a bad idea to use a little anti-seize compound on the threads of the new rods when you install them.

Your dimensions were accurate. My rods came out with a little persuasion, and went back in with a bit of anti-seize (thanks for the idea).

Thanks again for the response!
