Bob, 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.

Buderus 6A

Hello 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.

Runtal baseboard

@ December 29, 2013 2:47 PM in Runtal baseboard

I'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".
Thanks

JR, 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!

Steve,
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.

Steve,
What exactly is reversion? I have never heard of it.
What is the best course of action?

@ December 14, 2013 8:45 PM in Munchkin

Rich,
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?

I 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.

@ August 3, 2013 12:08 PM in Giannoni HX?

Call me naive but I do not see a big problem with these heat exchangers
I have installed a bunch of Munchkins, Alpines and one Elite plus with this type of exchanger over the last five or six years. I have not had one problem with them working wise or the annual maintenance wise either Can you explain to me the problem with them to me?. Is there a big difference between the other types of exchanges then these?

load

@ July 18, 2013 8:14 PM in Zone

Yes, that is the total house load. He want to keep almost every room on its own zone.

Zone

@ July 18, 2013 3:49 PM in Zone

Yes, the bathroom is its own zone. It currently have a three way mixing valve off the boiler. It has a t87 thermostat controlling the circulator. 

Zone

@ July 17, 2013 4:18 PM in Zone

I'm looking at boiler replacement job with a total house load of about 75,000 BTU's. I'm thinking about a mod-con with a buffer tank. The house has 6 existing zone and a 80 gallon indirect, the zones are kinda small and only doing a couple rooms each. They have a interior bathroom that has a radiant floor which is about 1,200 BTU's.
How would you guys pipe in this radiant zone? Mixing valve? I series valve? something else?
Thanks
