lead wipe

@ June 2, 2013 12:49 PM in Lead wiping

I took a class a few years back.It was through Bosces if I remember correctly.I will look for info for you,if they dont have class anymore I can show you(at least what I remember).

Great point

@ May 25, 2013 9:18 AM in Mr.

Heatpro makes a great point.I know with Nat Grid they offer rebates on Burnham.If you are not 100% on the Alpine try the ES2 with the Alliance indirect put an outdoor reset on top of that and you should have a highly competitive system.

putty

@ May 23, 2013 6:37 PM in Plumbers putty or silicone?

if using putty on marble make sure you get the right type made especially for marble.clear silicone is good for fitting sink,putty also maybe its a choice of preference.i usually use putty and always use putty on strainer(easier to remove in the future.)

larger pipes?

@ May 20, 2013 6:55 AM in is it a problem connecting a larger gas pipe to a smaller gas pipe?

just a follow up to the original thread.If I see a 1" meter bar with a six inch nipple with a 1x11/4 90 on it .rest of run is in 11/4.in effect is the whole line restricted to 1 inch.This is in the city so there is no regulators on meter,low pressure gas coming in from street.

but how do you compete

@ May 19, 2013 9:18 PM in I have noticed more and more shotty work

I much rather running copper and cast iron.This is how I was taught in NYC where plumbers in my old company took pride in their work.If a pipe was crooked my boss would tell us to rip it out and do over.Now after moving to Long Island I am being forced to use pex and pvc if I want to work.I find it almost embarasing to use pex as I feel it is a real step down from how we were taught.When I use pex I like to do a home run system but have been told by many it is overkill.I cant imagine how the old timers feel about it.Just my two cents.

good ?

@ May 18, 2013 5:53 PM in is it a problem connecting a larger gas pipe to a smaller gas pipe?

it has the same static pressure ok.now when i see a 2" meter set which increases in size to a 3" line what happens.is the 3" line in effect reduced to the capacity of the 2 " line feeding it.would this be a correct example?if i drained a 75 gallon water heater through a 3/4 drain line and then increased the drain line to 2" the heater wont drain any quicker.Would a gas line work on the same principle.

secondary zone

@ May 9, 2013 8:10 PM in Primary Secondary Problem

is the indirect piped in 1 inch or 3/4

check valve

@ April 28, 2013 8:56 PM in Check valve position

remote

@ April 27, 2013 1:41 PM in navien and odr?

I have in the past used this boiler with odr.This is why im boggled.Remote is plugged in.Boiler was runnig for 2 weeks.Went to install odr.boiler wont fire.we are told from navien,remote must be used as room stat in order for odr to work.one remote equals one zone.i used circs on this install and not zone valves.as i said i have rep coming this week so hopefully they can address the issue.Thanks for your input.

odr

@ April 26, 2013 9:39 PM in navien and odr?

i dont understand why a tech support manager said it wont work on more than one zone if not using the remote.What temps is your boiler running at and did you measure the efficiency of the boiler.Without the odr the boiler i installed runs great it just goes to 180 etc.I have a navien rep coming this week so hopefully he can figure it out.I must say they do have a good support team behind them.

odr

@ April 26, 2013 6:47 AM in navien and odr?

I know it doesnt make sense Chris.From what I am gathering from Navien (you get a different answer from tech support every time you call)the only way odr will work is by using the remote control as room stat,and this will only work on one zone.You can use odr but only on a single zone system.I am not knocking the product for what it costs it is great.I would just love to see it condensing a bit more.I am trying to get a rep to come to my job and correct the situation,obviously it is very possible I am doing something wrong.

navien and odr?

@ April 25, 2013 7:43 PM in navien and odr?

Hi,customer wanted Navien Combi ch 240. We installed boiler as per manufacturers specs,primary/secondary,sch80 on exhaust,etc.
So the boiler has been running for a couple of weeks now and customer is very happy which is great.I asked a heating consultant I know to come and calibrate the boiler and test for efficiency.
By the way there is two heating zones with a taco switching relay and room thermostats.
Boiler was running at 83% eff.it condensed a little on fire up but after a few minutes it stopped condensing.So we installed ODR.Now boiler wont fire.
We call tech support.It appears you cant use the odr if you are using two zones .We are told that the remote control that comes with boiler has to be used as the room thermostat and then the odr will work as long as you have only one zone.
I went to a Navien class and this was never mentioned,we were actually told to put the remote inside boiler away from the homeowner.
I am not here to knock Navien,I would just like to know if anyone has had a similar experience or is there a way to correct the problem because right now I do not have a condensing boiler.
Thanks.

buffer tank?

@ March 9, 2013 7:09 AM in Combi in small house

what if you used a 30 gallon storage tank to prevent short cycling,we have a customer with a similar situation who insists on a combi Navien ch 180.to prevent short cycling we are installing a storage tank.Will let you know the results

vxt i will give it a try

@ March 2, 2013 8:12 PM in automatic water feeder vxt or mcdonnell

thanks for the info.I always thought the mc donnell miller had a fail safe but a heating consultant in my supply house told me different.I tried their website but couldnt find a definite answer.Thanks again

@ March 1, 2013 6:55 AM in How to size a steam boiler

Thanks for your time and explaination much appreciated.I didnt mean to hijack the thread as I thought your answer covered everything.Just in case there is a few wondering that" if he cant size a boiler why is he putting it in",I work for a company and work with a licensed plumber but usually there is not time for questions on the job,so again the people here who take time to answer questions make work more interesting and challenging as you know they work to a high caliber.

automatic water feeder vxt or mcdonnell

@ February 28, 2013 9:22 PM in automatic water feeder vxt or mcdonnell

Hi ,in your experience which is the better product.My company uses mcdonnell miller but i was told they dont have a fail safe whereas the vxt does.in all dans books i have never heard him mention hydrolevel controls.

rod a ?please

@ February 28, 2013 7:57 PM in How to size a steam boiler

Hi ,I was just about to ask a similar question.Ok my total sq ft edr is 647.5.Ok i get that,now when i multiply that by the conversion factor of 240 I get 155400.Fine I go to the boiler manufacturer and i see in the Input column a In6=175.
Now I get confused here,dans book ,Lost art of steam on page75 he says 1.add up radiation square foot.(mine is 647.5..Next multiply by 1.5 so i get 971.25...Next convert to MBH by multiplying by 240.I get 233100..then select boiler from D.O.E heating capacity.I am now up to an IN9 ...what am i doing wrong.Thanks,I know I am doing something stupid

@ February 18, 2013 9:14 PM in garden hose for gas line

there is no way you did that work it must have been one of your English speaking employees(joking ok).I got to back you up here,the way I read that post I most definitely
agree with you,I certainly did catch a few racial undertones.By the way to the poster in the town where I work the civil employees do not resemble anyone from a "third world" country although there is no shortage of corruption.My two cents.Beautiful work by the way....

HDE a? on p/s on navien

@ February 16, 2013 9:56 PM in HDE a? on p/s on navien

Hi .I was on a job today and in the boiler room there was a new Navien combi boiler.It was piped like an atmospheric boiler,three pumps on feed and purge tee's on return.There was no primary/secondary loop.Homeowner said he did not have any problems with boiler.What is going to happen to this system or is it going to continue to run without any problems.Thanks for your time.

that is some pretty neat carpentry skills.any idea how long it took and what tools were used.very impressive

heel tee

@ February 8, 2013 9:13 PM in hot water loop off steam boiler

in my supply house they actually call them baseboard tees.the middle port of the tee is called the bull and the other two ends are called the run.so on the run of the tee one end is 3/4 and the other end is 1/8 threaded or female.the bull of the tee is 3/4.you would screw a 1/8 air bleeder valve into the heel or run of the tee.in the system you are referring to if that tee was at the top of the system and you opened the air vent you would let atmospheric pressure into the system.that pressure would in turn push the water back into the boiler and the water level in the boiler would rise.the vent would work the opposite way in which you wanted it to.explanation in the book explains it properly
