Atwood's disclaimer about installing the HottRod is a JOKE! I called their hand on it and talked with the factory. I said, "You guys offer basically the SAME thing with the "Hybrids" that have both gas and electric. They confessed that it wasnt an issue at all...BUT...there are some cases- as usual- that people would install one and as expected screw something up then blame it on Atwood....thus the disclaimer. FWIW, mine wasnt under warranty.
I think several have posted on here that use the HottRod (and the same would be with the Camco) without issue. I'm another. I removed my propane and have gone 100% electric and love it!
Here's how I hooked mine up and it works PERFECT! I installed a red light
at my counter. The reason being- as someone's already mentioned- if you turn the unit on with no water in the tank, HottRod proclaims it will burn out within about 30 seconds! So if the red light
is on, there better be water in the tank! I use a breaker as my switch and I cut a small oval hole in my breaker panel just so I can get my finger in there and flip it on/off (no accidental turn-ons). So my HottRod is wired directly into my Progressive electrical
panel with its OWN breaker.
CAMPYTIME: Be VERY cautious about installing the thermostat to your tank! I used heavy-duty nylon ties that go across the ends (dont block your emergency reset!). Then I used JB Weld to seal around the edge of it as HottRod suggested. I've been several hundred miles now and checked the other day and the thermostat is still very secure and my electric water heater works everytime with ZERO problems. But one final caution- should the thermostat come loose from the waterheater, it could cause it to burst...and this HAS happened from what I've read.
I have pics available of my install...
