Question About Rheem Water Heater RTG-74X
Drain Instructions...

My Rheem RTG-74XN2 Tankless Hot water Heater has a drain plug but has no instructions on how to drain the thing. I bought a new home, that did not come with a complete set of manuals. There is a warning tag at the drain plug, but no instructions.
