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

I see you're one of that rare breed that likes to get pissy
about the forum and everyone in it before even getting an answer to
your question.

Trying to beat the christmas 'pissy time' rush, are you ?

Asswipe.

There is no adjustment. They have built-in compensation. Enjoy your hot water!

Oscar, on top of the on/off/pilot knob is a green slotted cap with the
words
"Main Burner Pressure". And there's a pressure tap at the outlet.
These
two clues strongly suggest that adjustment is possible.

I do appreciate your effort and civility.

Typically factory set (correctly). Of course, a
tech could use a manometer, and check.

Yes and it requires a manometer to set it properly. Natural gas (methane)
valves have an internal regulator that drops the inlet pressure to 3.5"
water column, LP valves pass the 11" WC straight through, and have a smaller
orifice to match at the burner. IIRC 12" of water is .44 PSI. Given a fixed
burner and air shutter size manifold pressure controls BTU output alone.
Orifice size controls fuel/air mixture ratio and BTU output. Apparently
methane requires a richer mixture than propane/butane hence the bigger
orifice size and lower pressure.

You spend all your days and nights remembering what I write,
so you can drop it into conversation later? That's
flattering.

Those are not for homoaners to fool with. Do not fuck with it!

If you were supposed to be messing with it, they would have told you all about it in the manuals.

Touch those and you will lose all coverage for your homeowner's insurance and your family may die in their sleep.

Now, please get all pissy at me for telling you the God's honest truth and giving you the best advice you've gotten all year.

You homoaners make me sick. Better yet- go ahead and adjust it and die. You deserve it.

The manometer is no problem; I have a beautiful manometer.

Specs on the water tank call for "5in Manifold Pressure" (not 3.5").
No doubt there's an acceptable range (e.g. 4.5" ~ 5.5"). And I'd like
to know which direction to turn for higher and lower, as I don't fool
around with natural gas. That's why I'm hunting for Unitrol specs.

They're pretty consistent like that, I've found.
