Re: Reanimating Frankenstein - a gravity heat story
TRV work well with gravity system, perfect way to balance the heat in a constantly circulating system. No worries about deadheading the pump either.

Re: Am I blind? Not seeing the gas shut-off valve.
then that is the shutoff for the boiler.
I think you said it was 3 story. if that is the case the pressure needs to be around 18 psig to fill the system to the top

Re: Gravity compression tank connection
A B&G Airtrol fitting will prevent that. This is my preferred setup, since it eliminates the diaphragm or bladder which eventually fails, necessitating a completely new tank.
Re: Ever use an off brand press tool?
I’d think the jaws and tools would need to be designed as calibrated pair from factory. I know from experience jaws do go bad and have learned to replace if you get more than a couple leakers on clean jaws. I’d be concerned you would risk same issue with mismatched system.

Re: Gravity compression tank connection
If it is gravity the bladder tank will work but the microbubble air separator won't do much for you.

Re: Gravity compression tank connection
or just replace it with a bladder tank and microbubble air separator if you're already this far in.

Re: Low water cutoff not working after cleaning pigtail
Doubt you need a mask but it can't hurt. Gloves are a good idea.
Re: Am I blind? Not seeing the gas shut-off valve.
Just so you know B & G pump parts are very $$$$$. You may be better off using a wet rotor pump if you need to replace any circulators.
Re: Reanimating Frankenstein - a gravity heat story
I'd be a little concerned with the TRVs with gravity.

Re: Deviating from specification on head position.
On a fixed head like most Becketts, you pretty much can't do anything except that in some cases different size heads may be used with the same nozzle as the firing rate for the heads overlaps.
On a Carling most heads are adjustable. Start with the MFG recommended settings but do not be afraid to deviate if it doesn't work.
On a Carlin moving the head changes the static pressure the burner fan works against. Moving the head changes this pressure higher or lower and also changes the air flow through the burner and changes the flame retention.
In general, pulling the head back will give a more intense flame, maybe noisier, maybe a shorter flame. Moving the head foreword will make the flame less intense and quieter and maybe longer.
