Lightning rod therm-o-disc style 7025

[A~N~A]

I finally got my American Appliance Direct Vent Water Heater, mod # ARV-10, SER # C672338, circa 1978, taken out, cleaned out, fittings retaped, pipes insulated, and fired up. It was along day, but the wife is thrilled SHE has hot water again. Anyway, after all that my question is " There was a LIGHTNING ROD THERM-O-DISC STYLE 7025 zip tied to the pressure relief valve with wires floating in the air. What is its purpose and should it be correctly wired? If anyone could help with this it would be greatly appreciated. Since I do think it is a safety issue. THANKYOU

The item you are referring to is a thermostat for an add-on electric element (Lightning Rod) that may or may not be in your water heater.

Hope this helps.

THANKYOU Sir,and yes it is an add on. I thought it was like a thermostat, my water is hotter than HALIBUT, Apparently it is just a safety device, not a control. HOW do I know if it is functioning properly, and is it adjustable. DONT. Want to burn skin or go BOOM.
THANKYOU again for your time

A~N~A,

It is t-stat - designed to do one primary thing -- function as a safety device to stop the heating process whenever the temperature set-point is reached. It is also a control because the set-point is adjustable.

All of the Lightning Rod t-stats were adjustable. If yours is not, may not be the original t-stat. Make sure it is hooked up correctly - the incoming electric goes through the t-stat to the heating rod. Look for a sloted "post" on the t-stat - possibly with a plastic pointer surrounding it - turn it counter-clockwise to lower the temperature, etc. You'd like to have your water heated to approx 130 degrees F.

An unseen part of the P&T valve sticks into the water in the tank. The t-stat should be firmly attached to the P&T so it can sense the water temp adequately.

The P&T will lift and relieve the pressure before anything goes boom. It opens at 150 PSI or 212 degrees F, whichever occurs first.

p.s. The HOTT ROD add-on electric element system mounts its t-stat to the back side of the water tank.

Hope this helps.
