Re: WarmRite System - No flow
You need an air seperator or at least an air vent on the high point before the pump. As it sits, air can collect there and you can loose prime on the pump.
You also mentioned open loop. How exactly is this setup? Open system and stagnant water for 6months is a bad idea.

Re: Multiple Steam Boiler Sizing Methods
A lot more work and a lot more piping to make steam work successfully with multiple boiler. It can be done but $$$$.
Now if you install two boiler and keep 1 boiler valved off and manually change them over manually then there are no issues.
The issues have to do with multiple boiler on line at the same time. Controlling the condensate return can be difficult. You would need a boiler feed tank if the boilers have different water levels, overflow traps to control water level from condensation etc.
If gravity return you could make a pad so the boiler water levels match.
But there are a lot of issues and increased cost with multiple boilers.
Re: Any ideas where to locate a DOOR for an old TRANE UNIT?
You need a good commercial sheet metal shop. Don't bother with a residential duct guy. I am sure in a city like Memphis there are a few.
Re: Hot Water system Circulation Issues
Zone valves and a flow check should never be together on the same system. You can manually open the flow check by turning the lever on top and leaving it that way.
However, I doubt if that’s your main issue. You’re either air bound or the zone valves are not opening. I’m assuming your circulator is pumping in the right direction.

Re: LP boiler Shuts off completely after reaching room temp
Something is still not right. That is a standing pilot gas valve, there is no connection between the pilot and the controls. There's no way for the aquastat to kill the pilot flame.

Re: Corroded connectors on new boiler.
Two disimliner metals but it is ok. Take them apart clean them up and put back together. Do it befor it gets worse.
Re: Hot Water system Circulation Issues
If you have zone valves then that red flow control valve serves no purpose at all. The circulator shouldn't be buzzing, it should be silent.
Re: Hot Water system Circulation Issues
most often when you open a system, to replace a pump for example, you need to purge both zones. A single air bubble can stop circulation.
What does the pressure gauge read?
