Very cool! Where did you purchase?

Or it could be a home made vent (although it should be pointed up).[:-paperbag] I like the galvanized piping too!

I'll ask about sharing the pp presentation. Nuk, nuk... I just said pp. Ok, time to grow up. I'll be 49 this year and I still think pp is funny.

Hi Mike: Roger Wilco takes care of communications. You can talk and still go anywhere you want on the net. Regarding the trainer; he has a powerpoint presentation however, we will not be able to view that - this will be real time communication - no video. I would think that he will just go over the verbal part of the presentation. If you would like to install Roger Wilco and try it out with me first that would be fine (or anyone else here for that matter). Would be fun to meet in Mikes chat room and talk real time as well. Then we will really need the 5 second delay! Let me know.

Good Morning Mike: This will be very easy. 1. You will need to purchase a microphone if you don't already have one. Get the headset/boom style mic. You can get this at a local computer store - I'd stay away from Radio Shack. They sell boom style mic's but they are the type for cell phones and the jacks are different. They might have a usb style mic but you don't need anything fancy for this. The cost for the mic should be around $20.00. I have the boom type with the single ear speaker. You will need to plug the mic into the 'Mic in" port on your sound card. Don't hook up the ear speaker, just use your existing speakers. 2. Install Roger Wilco on your computer (we will have to wait and see first what the reps have or want to use however, I will recommend RW to them). It is very easy to install and configure. You can read more about it here http://rogerwilco.gamespy.com/ however, DO NOT download the latest version. It comes with gamespy crap. I have an early version which is just the program. I can upload it to your site for all to use. A little better program is teamspeak but it can be a bit of a bugger to setup. If anyone has any other communication programs that are free and simple to use please let me know. 3. To talk over the net you will use this program. I have a cable modem with a router that has a dynamic IP address however, it hasn't change in quite some time. The IP address is the address of your computer ie.68.215.56.180. In Roger Wilco you would type in my IP address and bingo - instant communication. We can have everyone join on my IP. This takes care of voice communications. 4. We set a date & time. We use Roger Wilco for communications and we meet on your web site in the chat room. 5. I would suggest we submit questions to you in advance and when the guest speaker is done giving their talk you can read off the questions. We can also use the chat function to type in questions as they may arise but without a moderator it can get out of hand with people talking over each other. That's about it, very easy really. If you would like to try Roger Wilco let me know and I can send it to you or anyone else for that matter. Ron, from Burnham Boilers, said he would call me back today. I have left messages for both Weil McClain and Bell & Gossett so we will see what happens their. I was planning on going the the St. Paddy's day parade here but we go hit with over 8" of snow yesterday - oh well. Think I'll stay in and have a green beer! (Can I get MRCs for this?)

Mike.. I understand, I was doing a Gen. Patton imitation - from the movie, sorry. A little off the beaten path.

Very easy Mike. We will use my IP address as the host for voice communications. We will meet in your chat room at the time that works for all. You should be the mediator to keep things on track. Easy peasy. If this works it would be great for things like EFIS, pools, you name it. A once a month round table. I just hope I'm not speaking for resources that I shouldn't be.

Ok, I'm a sonuvabitch - I like that. From one sonuvabitch to another! Kurt, I'm using Mike as a translator here.

Well Kurt, ya got me there. Mench - I have the Webster's new universal unabridged dictionary, all 2,347 pages, 320,000 definitions, and I'll be damned if there is a Mench in the bunch. Is this a new scrabble word? Other than that I'm glad you like the idea. I hope I can get a few reps to buy into it. You will need to buy a mic and get the software to talk online. The software is free btw. I still have to set it up with the rep's though.

Thanks George! Regarding the heat issue I would think that they would design the materials to compensate for the temperature, besides the delta t between supply and return is 10 degees - 15 at best?? - it's like condensate return pumps, steam traps, air conditioning compressors under the hood of a car in Arizona, HVAC systems on aircraft (let's not mention the heat shields though). I hope this will take off. I think it would be great to bring manufacturer's reps here to do on-line seminars regarding their products and proper installation methods. A mind is like a parachute - it only functions when open. I like that tag line.

Well, I have called Bell & Gossett, Weil McClain and Burnham Boilers. Left a message at B&G & Weil McClain but had a great conversation with Ron Beck from Burnham Boilers Corporate. He is checking into their communication software and said he will call me back tomorrow. He also has a 1 hour point presentation he can put on for HI organizations regarding boilers and pumps. I'd like to get as many people involved for a real time round-table so that we can make his time and possible future "on-line seminars" worth while for these individuals.

Hi Chad: When you size a pump for a system you need to know all the particulars of the system, boiler, how many feet of piping, how many fittings, etc. This all equates to pressure drop... Ya know I had a thought. They have numerous communication programs like team speak and roger wilco for internet real time communications. We could even use ICQ or Messenger for a white board or something as easy as Mike's chat room for typing or a combination of the above. Mike's chat room would be the base for the discussion. Is that ok Mike? I would be glad to talk with Armstrong - Bell & Gossett - Weil-McLain, Burnham, whoever you guys would like to see. We could put on a real time mini-seminar on the topic? Explain we are home inspectors interested in continuing education. Anyone up for it? I'll do all the leg work.

Head off the pump is the delta P (if the suction and discharge side of the pump were at the same pressure the pump would be off or broken, take your pick). When a pump pulls out of the boiler it is not increasing the operating pressure of the boiler - when a pump discharges into the boiler it raises the operating pressure of the boiler hence the verbiage from Bell & Gossett about it tricking the pressure relief valve. In a small residential application this doesn't account for much with a fractional HP motor but on 15+ HP circ pump it can account for quite a bit of added pressure. In the end I'm comfortable with the manufacturer's recommendations.

Well it took some hunting but I found what I was looking for over at Bell & Gossett. Great article on pump placement. http://www.bellgossett.com/Press/Counte ... 2001-A.pdf

Hello George: Circ pumps should pull out of a boiler vs. pushing into a boiler. Attached is a link from Weil-McLain. I'll look around for some more information on this. On quite a few larger commercial job I have seen the circ pumps pushing into the boiler and the maintenance man was always complaining about the relief valve weeping and too high of a pressure on the boiler. I have also seen 50# relief valves on applications where there should only be a 30# in a attempt to rectify a pressure problem with the boiler due to improper pump placement. http://www.weil-mclain.com/contractor/T ... SB0206.pdf

Hello Dennis: Were there two separate condos in one building, each condo with it's own boiler sharing a common expansion tank? Also, looking at the picture the circ pump is on the return line to the boiler. The pump should be located on the supply line. If the pump is pushing into the boiler it is wrong (on bigger systems with larger horse pumps they can lift the RV when the boiler is running at the higher limits). If it is pulling out then the flow on the boiler is bassackwards.

Hello Mike: It was Darren that was trying to upload the picture.

Hmmmmmnmmmmmmmmm [:-bigeyes] Mike?

Hi Darren: Rename the file to chatham.jpg and then upload it - it will work then. I think the underscore _ in the file name is preventing the upload.

True story. I just graduated from a local HVAC tech school back in the late 70's (complete with leisure suit, ok, the leisure suit was made up but helps in setting the tone). I went over my brothers house and offered to check his counter-flow furnace for "proper operation". I set off a smoke bomb, in the furnace, to check the heat exchanger. After my brother, his wife and 3 kids and I evacuated the home for about 15 minutes, we returned to find the house was still very smokey, the parakeet and hamster had passed away but much to our gratification the smoke detectors were announcing an emergency. His wife had no sense of humor about the whole experience but my brother and I had quite a few good laughs reminiscing, over a few cold ones, from time to time.

Way beyond the scope. I've used this only on setting up gun burners on boilers. I'd be very careful about verifying the integrity of heat exchangers. Closed System - Unable to inspect, The heat exchanger portion of a gas or oil fired heater is difficult to access without disassembly, and cannot be adequately checked during a visual inspection. We recommend a service contract be placed on the unit and a licensed HVAC contractor called to verify the condition of the heat exchanger. One way we use to check heat exchangers - spray a salt solution into the burner/heat exchanger, check at the diffusers with a halide torch. Another method was a smoke bomb (for those with big brass one's.)

Hello Darren: Your pic got lost in modem land, need to try and upload again.

"Pullin' on spenders, spittin' a little chew out" Twernt nothin', shucks. I still think Chad holds the high score though. Mike, the link for the screen print program is http://www.almac.co.uk/personal/tdocher ... rint32.zip I believe it's freeware - best kind.[;-xmas]

Sorry Mike, thread drift but it's like krispy kream doughnuts... Ok - I hope your all happy! I now have to go back into counseling however, I have 322.9! Download Attachment: p.gif 93.57 KB

I have canceled numerous inspections trying to beat Chads high score - I will you know, yes I will, and then the world will bow to me - hehe, won't be long now! Ah, the nice men in their clean white coats.
