@ July 25, 2012 12:41 AM in Tidbit #5: a guessing gameBob, you raise a good point. That crawlspace that Plumdog describes would very likely be a permit required confined space. As you said, routinely entering places like that should make you pause and re-think what you might encounter. The actual OSHA definition of confined space and permit space is copied below. Entering a permit space does require jumping through a few hoops first.
"Confined space" means a space that:
(1) Is large enough and so configured that an employee can bodily enter and perform assigned work; and
(2) Has limited or restricted means for entry or exit (for example, tanks, vessels, silos, storage bins, hoppers, vaults, and pits are spaces that may have limited means of entry.); and
(3) Is not designed for continuous employee occupancy.
"Permit-required confined space (permit space)" means a confined space that has one or more of the following characteristics:
(1) Contains or has a potential to contain a hazardous atmosphere;
(2) Contains a material that has the potential for engulfing an entrant;
(3) Has an internal configuration such that an entrant could be trapped or asphyxiated by inwardly converging walls or by a floor which slopes downward and tapers to a smaller cross-section; or
(4) Contains any other recognized serious safety or health hazard.

@ February 24, 2012 5:47 PM in Lochinvar Knight boiler problemsHello cricka,
Really need to see several photos of your system. How it is piped up and the more photos you can post, the better. Even though you have a pretty good size home with perhaps marginal insulation, the KBN400 seems a bit large for your home. If it is very oversized, this can lead to not getting the savings that you were expecting. Post some pictures of the venting as well. It sounds like some of your issues may be installation related.
I have a Knight KBN80 that has warmed our house since 2007 quite flawlessly. Our place is about 3000 sq. ft. and fairly well insulated for your comparison.
People here can help you if you give more info.

@ November 25, 2011 8:38 PM in knightly cleaningThe trinity wand looks like a handy tool but I have been very happy using the little ball valve on the end of the hose that I have. Very simple and it works. The credit card is handy and flexible and won't break off in the hx so I'll just keep using it. There really doesn't seem to be any efficiency difference between before and after cleaning, but the amount of crud isn't so much. I suppose if the air or gas was really dirty things would be different. Bottom line, I love the boiler. It has the best controls out there and since I do the maintenance, I'm still saving a bunch of dough.
@ November 25, 2011 8:26 PM in Thanksgiving Day Steam BoilerI bet that some family is thankful and they don't even know how thankful to be. Every bit of that install looks great. Way to go!
@ November 16, 2011 5:48 PM in knightly cleaningHere are a few pics of the latest cleaning. The amount of crud was about the same as every other year. Wildlife residing in the burner also similar to other years. I think one of these days I'll put an intake filter in to keep these little guys out. The credit card got lots of use between the coils and although I probably didn't need to lightly clean the flame sensor and igniter I did anyway. The whole process takes about 2 1/2 hours and yes, I'm kind of slow, but thorough. Pressure washing the coil used about 10 gallons of water and my system of sucking it out with a wet vac really works well. This system has worked flawlessly since installed in 2007.
@ November 5, 2011 12:09 AM in Lofgren case coming to a head...talked about the faulty boiler by brand name. My memory is increasingly fuzzy these days, but wasn't it a case of improper venting installation and not the appliance?
If I'm mistaken, sorry about that but it seems that we often hear news reports of faulty equipment when the actual issue was an incorrect or disconnected vent system.
As a side note, I'm a bit surprised that there is a statute of limitations on negligent homicide. Also, as a member of a regulatory agency, I do cringe when discussion turns to charging inspectors with negligence. At the same time, it certainly seems inconceivable that if the inspector actually looked at the installation he did not see serious issues. (Again, I don't remember the details of this event). None the less, very sad all around.
@ August 15, 2011 3:54 PM in Boiler pipingThe Knight install manual has great diagrams. Page 40 might be what you are looking for.
Hope this helps.
@ July 7, 2011 8:21 PM in Some prayers needed PLEASE !Please know that we are keeping you and your family in our thoughts and prayers. I've seen remarkable recoveries from such injuries and hope for a speedy and very good recovery for your family. If you don't know about CaringBridge, (http://www.caringbridge.org/) it might be something to look into.
@ May 2, 2011 7:07 PM in Thoughts on DHW circulation return controls for MFD settings...Hi Mark. I've been using the small version for single family residential for a few years with good results. (When it was Laing) I did chop out the timer because it was a bit noisy and plugged it into an electronic timer. Works great. Low velocity so it shouldn't eat the pipes.

Happy B-day Dan. All the best.
@ January 13, 2011 9:55 AM in Thanks for that DanOk, so I scan the Thursday newletter like always, scrolling down the page and come to the "We don't sell this but" and figure Ok, I'll check this out since Dan really, really thinks I should.
After just a few lines into the first review, my day has been changed dramatically. I'm laughing out loud at my desk and co-workers need to check my condition.
Thanks Dan. I don't know how you find this stuff. There are some exceptionally creative people out there.
@ December 16, 2010 9:48 AM in How's your weather?Perhaps you have seen the deflated Metrodome and reports of a foot and a half of snow here in the Twin Cities. Saturday was lots of fun digging out just to have the plow come by three times building and rebuilding the snow hedge at the end of the driveway. I know the folks in Upstate New York laugh at amounts like this, but hey, it's still a lot of snow. The below zero temps that followed didn't help much either.
But on the bright side, my little Knight was just humming along.

There was lots of good input on this one. Might be the one you wanted.
@ October 18, 2010 12:25 AM in anode questionI've replaced the crusty aluminum anode with a nice new magnesium one and the next time I flush the tank, I don't expect to see the milky looking water that has usually been present. The old anode was five years old and I hope to get a similar life out of the new one.
Thanks for everyone's input and help.
@ September 25, 2010 8:31 PM in anode questionI wanted to check this out a few years ago, but today was the day. With the amount of crud on this thing, does it still work? I scraped off what I could and put it back in, but is this normal? And since it is still mostly still there, do I need to replace it, or what? I suppose that most folks don't even look at anodes ever, but I did. It's set to 140 degrees, tempered down to 120.
I appreciate any and all points of view.

@ August 9, 2010 6:40 PM in Can I convert a Taco 007 to a Taco 007-IFC?It will probably be a long time before you need to think about replacing your Taco circulator. But if you do, you can use the guts from the old one by removing the 4 screws that hold the can to the volute and just popping it out and changing it.
@ July 16, 2010 12:16 PM in Man dies in manhole incidentDave, you are correct. Both types of alerts are required although the standard does not directly say so. In the appendix that offers explanations for how to comply with the standard, it says you need both.
Even though the news article only said "lights flashing", that does not mean that they got it all right. It is troubling that emergency personnel can lose sight of their primary responsibility which is to take care of their own safety first. If they go down, they can't save anyone, can they?
