Installing My 110k Tomorrow!

I bought mine and installed it myself last April...I have used it all Summer for hot water...I fired mine right up with coal..no problem...Feel free to use me as a resource for any questions u might have...
Don't know if Matt told you, but when using coal, you need to FIRST set the adjustment so that when the boiler is firing full throttle, you have about 1/2 inch or so of ash at the end of the carpet so that you don't dump any burning coal..this takes time...maybe maybe several hrs..as you will be adjusting in 1/2 turns only on the adjustment (screw/hardware?)...

So to do this..you need to keep a demand on the boiler...(either jump the t-stat terminals on the boilercontrol, or turn up the heat in the house), AND have a way to dump the heat..(you may have to open windows and blow out heat)...

AFTER you have THAT set, then you need to set the idle timer control...

If you need help with that..give me a shout!

Thanks, Don.

I've been bugging Matt prior to the installation, so I might need to use your help once I start up with the coal

Actually, Dave and Matt have both been great, I feel bad bugging them having seen their shop. Both are very much 'hands on' guys, and I feel bad every time I call them.

That won't stop me, but I feel bad...

A Spirovent is a "great choice" for air elimination.

With that said, did you decide to use the old air-cushion expansion tank? If so, you really don't need the Spirovent. Pipe the boiler and tank as show in the AA Boiler manual:

Pfft.

Yeah, I knew that...





Seriously, that was an 'oh *censored*' moment right there. Had the lines half run, and was about to post about how best to hook in both the expansion tank and the water feed.

Luckily, that air eliminator just got here.

I guess I got locked onto the piping for the new tank I was going to buy, and forgot that bit about the old tank.

Rob, you ever get down my way, I'm buying you dinner.

In that pic, how important is that backflow preventer for the system?

Good Luck also having my new stoker put in today.

I don't see a "backflow preventer" at all. Are you talking about the flow check in the supply line? If you don't want gravity circulation through the boiler, you should use a flow check.

You are very welcome! Glad to be a help! And I feel the same way about bugging the LL guys...I know they mean well..but it must be overwhelming for them...Matt will be the first to admit that his tone of voice may come thru as 'irritated' sometime, but is also aware of it and really does want to help..

So..yeah!..anytime...feel free to pm me with a question!

I jumped in here with out reading all the prior threads, so forgive me if this is not pertinant...

A backflow preventer is a different animal that is used for a fresh water supply line...

A Flow Control valve is needed, and should be placed on your return line to the boiler...(Careful! Pay attention to the arrow on the valve and make sure you have it installed so that the arrow and the flow are in line)

How many zones and how are you zoning? If you use the spyrovent, you need to use a bladder type expansion tank. If you use the old air cushion tank, there is a special fitting for that. The spyrovent is an excelent product, just get yourself a 1/2" cap to cover it when you purge it will keep everything dry as they have a tendency to spit. The Taco one doesn't spit. I now use the Watts 112A as I pipe just about everything primary/ secondary.

Also, do yourself a favor and pipe your makeup water between the spyrovent and the expansion tank

why you want to pipe it that way, this way I do my right also, thank you

You want to feed your water at the point of no pressure change. Also you want to pump away from here.

I understand now, thank

Alrighty, here's today's update:

Everything that needs pipework, has pipework.

4 leaks and I had to add a valve between the expansion tank and the old boiler (doh).

So while I fixed the leaks, off to HD to get the valve.

Repressurized the system, had one last leak.

Dumped the system one last time, now everything is tight and dry.

But.....I didn't put that flow control valve in (calls for on the feed side). And I'm too damn tired to finish it up tonite. So back to HD tomorrow for a few more fittings and the put it in first thing in the morning.

A buddy of mine is coming over Monday night (was going to be Sunday, but something came up) and hook up the oil and controls and then it gets test fired. Makes having the old boiler still in place handy, as I'll be able to keep making hot water when I need it. Put in a programmable thermostat while I was at it.

So far, this has been a remarkably low stress job. And it would have been much prettier if I had bought the new expansion tank, not having that makes this install a bit trickier coming off the pressure relief side of the boiler (the high limit goes in the top of the reducing fitting) but I 'think' I have it where it will work.

Thanks all for the help so far.

Somehow I missed that you were leaving the old boiler in service. Do you intend to circulate continuously from the LL110 to the oil boiler? Is the oil boiler isolated? Please explain your setup in greater detail.

The old boiler is still in the system, but it will be valved off when the new boiler will be running.

It's a big bastard, and taking it out of the basement was going to be a nightmare, so I left it in (still works, no reason to toss it). I'm not going to recirculate, but I'll run the old one once or twice a year to keep it going.
