@ July 16, 2014 5:03 PM in Gas PipingThanks for your reply Tim. That is what I was going to do. I just had a debate with another plumber friend of mine about dropping pipe sizes on long runs.
I thought poly pipe was corrosion protected, if not what would you recommend?
@ July 13, 2014 2:27 PM in Gas PipingI'm looking at a job I need to install a gas fired pool heater. The heater is about 35' away from the house that piping will be underground. I need to pipe from the meter to where it will meet the outside underground piping approx. 22'.
On table 6.2(a) of NFPA54 at 60' i need to use 1.25" blk pipe to 400,000 BTU's.
on table 6.2(f) for poly pipe I need 1" at 30.
My question is can I go from 1.25" blk after the first 22' and then go to 1" poly from there?(I have an 50" roll in my shop)
Or just keep it 1.25" which I normally would do.
@ June 16, 2014 6:33 PM in Recirculating loopGordy,
Thanks for your reply. That is the usual way I also do it. This one has got me.
I really haven't seem a answer to my question just some good ideas. I'm going to install a pump on the return manifold back into the water heater and incorporate part of Hod Rod's suggestions
@ June 15, 2014 7:43 PM in Recirculating loopGordy,
Are you suggesting that I run a pipe from each bathroom/sink location back to the water heater and tie it in with not check valves, circulators?
@ June 1, 2014 3:22 PM in Recirculating loopIce,
I should said it a different way. Each bathroom will have separate hot and cold water supply piping from the boiler room. Each set of water lines will have isolation valves in the boiler room as per contractor request. He also wants a recirculating loop to each bathroom. This was the only way I could think of doing it. Sorry for the misunderstanding.
@ May 31, 2014 9:35 PM in Recirculating loopThank you all for your responses.
Ice, I have done the recircs before with an aquastat in the master vanity to keep the water a pre-set temperature. I do not think it would work well with bathrooms on three floors and with a home run distribution system.
Hot Rod,I like drawing 7-5, I could add balancing valves on the manifold and thermometers on each loop back from the system. Can you tell me what the purpose of the bypass (#1) is for? I see no need for it..
@ May 27, 2014 11:57 PM in Recirculating loopRoughing a house with six bathrooms on three floors. The owner wants a hot water recirculating loop. Each bathroom will home runs (PEX) from the boiler room to each bathroom. Looking for opinions on how to do. I was thinking run a 1/2" PEX line to each bathroom, looping at the basin or in the floor and back to the boiler room, Connect each loop to a manifold and to the indirect heater. I will be using a Buderus GB boiler which has a connection to turn the recirculating pump on/off a timed intervals
Any comments would be great.

@ January 24, 2014 7:19 PM in Problem with fuse socket on Buderus GB142 UBA3I have a broken (malfunctioning) UBA3.6 that I replaced about three weeks ago, your welcome to it.
@ January 7, 2014 7:43 PM in Buderus 6AWent back to the job today. It turned out to be the UBA. replaced it and all is well again.
Thanks for all your help.
@ January 6, 2014 8:44 PM in Buderus 6ABob, I'm going to the job tomorrow AM, I do not understand what you mean by installing a fuse. What is the purpose of the fuse?
Iron, The incoming gas pressure is 7.7"WC, set the gas/ratio to -0.03. The old transformer was reading about 19 volts.
@ January 4, 2014 10:31 PM in Buderus 6AHello All,
I have a GB that I looked at before Christmas it was giving a 6A code, the flame sensor was changed before I got there so I do not think that is the problem. I cleaned and serviced the boiler (it has not been serviced in a couple of years) still had the same problem. Checked everything in the manual and found nothing wrong. Called Buderus and spoke to a tech, he walked me through other tests. Found it to be the 24 volt transformer, changed the trans and all seemed good. Got a call tonight the 6A is back. Does anyone have the procedure to check the transformer? I'm thinking the new went bad.
@ December 29, 2013 2:47 PM in Runtal baseboardI'm looking at replacing some Slant/Fin 30A baseboard with a section of Runtal UF-2 baseboard. Is there anything any that I should be concerned with? Pressure/GPM drop through the rest of the existing Slant/Fin? The heating loop is 3/4" and the Runtal would be bushed down to 1/2".
@ December 25, 2013 1:09 AM in ChristmasMerry Christmas to all. Let's remember the reason for the season and say a prayer for some who needs one. God bless!
@ December 18, 2013 10:24 PM in MunchkinJR, I have not been back to this job. I will be there after the new year to do other work. I'm going to extend the existing vent to see if that helps at all( I will be the basement to keep an ear on it). The 199 is a rev2, all the components are just fine no sigh of cross contamination, swirl plate is good I changed the target wall and burn refractory about 8 months ago, condensation draining fine and the burner is clean. Unit is firing fine as per specs.I will let you know what happens after the new year. Thanks!
@ December 16, 2013 9:14 PM in MunchkinSteve,
Thank you for your responce. I will look at the venting and see if I can remove the stainless steel plate and do like you suggested. Hopefully that will work out.
@ December 15, 2013 8:38 AM in MunchkinSteve,
What exactly is reversion? I have never heard of it.
What is the best course of action?
@ December 14, 2013 8:45 PM in MunchkinRich,
The swirl plate was/is clean and looks normal. There was nothing blocking the air inlet.
What did the rebuilding kit due? What parts did you change besides the gaskets?
Is this a problem HTP knows about?
@ December 14, 2013 4:59 PM in MunchkinI have a munchkin 199 which has been installed for about 6 years. I do the maintenance on it very every year. I was working in the basement and noticed the boiler was starting very rough (almost like a tiny explosion). I put on my Fryrite and all the numbers are in the allowable ranges. The CO2 was at 9% Co was 55PPM at high fire. The incoming gas is 7.92"WC. The unit runs fine after the burner starts. The exhaust and air intake are one of those stainless one piece units. There is no sign of cross contamination. Any help would be great.
Merry Christmas to all.
