Out of pure curiosity, I'd like to know how one adjusts the Unitrol gas valve on my 50-gal water heater. Whirlpool customer support hasn't a clue, and Robertshaw has hidden its Unitrol information pretty well.
The water heater poses no danger, but no doubt one of the alt.hvac thunderbolts will explode. I'd appreciate an accurate answer from a cool sober head.
Thanks, JP
