Re: Weil Mclain Ultra Boiler, E 02 error and water dripping out of intake snorkel

I realize this is an old thread. I was wondering if OP had any resolution to water dripping out of the intake snorkel as I have the same problem with an Ultra 155 Series 2. Outside air and exhaust are through Weil Mclains vent (same as the one in the picture). However this is mounted up 10 feet from the ground with no inside corners or other encumbrances. This problem has been going on for a long time, it existed when I bought the house 16 years ago. Boiler throws E 02 codes occasionally, especially when weather is cold. (In fact I set up a remote reset function so i can reset when away from the house.) Weil Mclain tech support when told of this said "that's impossible". Is it water in the propane? Any help or insight greatly appreciated.

Re: Can't get steam fitting on tight enough

You can grip it at the fitting like a ford wrench. I have some insanely large channelocks that I bought when I went probably 2 sizes bigger than I should have but they have been useful for some things. You also have to buy real channelocks, I have had several brands of knockoffs and they never hold well enough at the slip joint.

Re: Steam Boiler Venting

The chimney should have a level II inspection, which, if properly done, will indicate a ss liner sized to the appliance. I've never found a sweep who has found a masonry chimney lined with TC tile that meets the code, much less that has held up for any length of service. Keep in mind tiles are 2ft long. They have joints. Those joints are laid in Portland cement-based mortars, usually a type N. The code calls for a medium duty non-water soluble calcium aluminate refractory cement mixture. Never seen it in the wild. The liner will also size the flue to the boiler. Use a smoothwall ss liner so you don't have to derate it 20% for corrugations.
Listed liners require a rain cap. Spark arrestor screens are optional and limited in opening size so they neither clog easily nor allow birds in. Bats and bugs can get through. Sweep the liner into the room with a broad radius at the base- no tee. Not needed and adds flow resistance. With 2-3" of liner into the room, attach an appliance connector for the transition to single walled unlisted pipe. I use rigid ss chimney liner as connector for a permanent connection. I incorporate a slip section for easy disassembly allowing inspection or service and re-assembly.

Re: Redoing Boiler Room / Manifold Setup For House Radiant Heat System

Being a novice,

You had a gravity hot water heating system, and you gutted it????????

My first comment on this rat's nest is this, you need hot water storage with a pair of black iron threaded pipe headers, one for hot water delivery with one circulator pumping away from the top of the New Horizons tank feeding the zones and the other as a common header for cooler return water back to the boiler sump.

I do not see a low water cut off switch, Where is the triple aquastat??

Adding a New Horizons 490 gallon fully insulated rectangular hot water storage tank would provide you with a larger buffer of hot water storage.

Replacing the bladder tank with a 30+ gallon steel compression tank with an Internal Air Separator and airtrol valve connected to the top tapping in the steam chest would allow you to have a simple system that has a 1/3 air 2/3 water tank to maintain the point of no pressure change and also save your knees from bleeding air out of the system as you will no longer require automatic air vents that will leak. .

Re: Have you noticed?

Hi @Intplm. , I guess I fired all of the not-so-good customers, so these days there is no trouble. I'm not exaggerating much when I tell you that they roll out the red carpet, hang on my every word, and throw money at me. Maybe it's the white beard. 😏

Re: Fire in chamber and smoke in basement

The resistance of each spring to ground should equal the total resistance when measured across the two springs.

Your combustion test results look decent, I only see one draft reading and I assume it was taken in the stack. I don't measure draft in mbar, I measure it inches of water column so I can't comment on the draft measurement. You need two draft measurements, one in the stack and one over fire. Hopefully oil pump pressure and the same nozzle was in the burner when these measurements were taken. Even so, a combustion analysis needs to be done anytime anything is changed, even the burner nozzle. I have had different results when installing new nozzles even when I put in the same exact size and spray angle nozzle from the same manufacturer. I've also measured higher and lower oil pump pressure on equipment that was supposed to be set from the factory. Gotta check this stuff every time you work on a oil burner. The tools are expensive, that's why it's usually best to call a professional.

Re: Water Heater Expansion Tank Pressure

Thanks, Larry. I actually have a similar setup for my closed loop heating system with gauges on either side of the prv. But, there is no PRV on my domestic hot water or any of the main feed coming in so I was just going to ignore it for now and let it operate at 70psi. Perhaps next spring I can remove that globe valve and replace it with a PRV???

For now I'm going to monitor the incoming pressure and keep the expansion tank for the water heater at that same pressure.

Perhaps, next spring I could put a pressure reducing valve in place and set the PSI to something like 60 and add some valves/gauges perhaps.

Thank you
