Re: Meter accuracy
My boiler is runs at 90,000 btu (set by orifice size) and I was having problems. When I checked the pressure before the boiler gas valve it was 8.3" wc, when the boiler started up that dropped to a little less than 5. the output of the gas valve was 3.5" and bouncing all over the place.
I had the gas company out and they verified the pressure drop was unacceptable. they replaced the pipe coming in from the main in the street with a new 1-1/4 feed and a new meter that connected to the 1" house main. Problem solved.
Note my internal main is 1" not 3/4", bigger is better. Its conceivable your meter is off but I would have the gas pressure checked at the input of your boiler gas valve and see if it drops excessively when it starts up, then check the output to make sure it's set correctly.

Re: Meter accuracy
Your sure the boiler was firing the whole time, and the water heater was off.
It's not unlikely to have a .5% margin but that's a lot.

Re: An Electrical Question
As long as your not drawing huge spikes of current and that cable is twisted pair you should be ok.

Re: An Electrical Question
Induced noise should be in the millivolts, and thermistors have a wide enough swing that the controller input circuitry should not even notice. A platinum RTD would be far more likely to see noise, but it could (should, actually) be filtered out by the controller.

Just the common (R) and the break on rise (B). Leave the make on rise (W) alone.

Re: Question about water hammer and near boiler piping
EDR stands for Equivalent Direct Radiation. Every square foot of radiator surface you have will radiate 240 BTU's per hour when the room air temperature is 70 degrees and there's 1 PSI of pressure inside the rad. The EDR you calculated for your rads has to match or be close the the amount of EDR the boiler can supply. The boiler has to be large enough to supply enough steam to fully heat your rads. If your calculations are correct the boiler is too small, have your contractor go over his calculations with you. The boiler evaporates water into steam and the rads condense it back into water. They need to be equal or nearly so. Right now your boiler can't match the rate at which your rads can condense steam.

Re: new boiler odor
If you post some pictures of your boiler we can help you find the proper skim port (if the installer put one in) and walk you through the process. It is fairly simple, but time consuming. Definitely DIY friendly. I assume you know the installer did not perform this step? Have you watched the water level in the sight glass while the boiler is running? If the water is bouncing more than about 3/4" it most likely needs skimmed.

Re: Recently had thermocouple changed now problems with spitting gurgling pilot light
A happy customer tells his circle of friends.
A unhappy customer will tell the whole world and not know it.
My old dead boss always said "Fix it. Whatever it takes to make them happy". "The good will is cheap at twice the price".
If it was working before you got there, and after you leave, it doesn't work properly, no amount of excuses will ever convince someone that you didn't do something wrong/Maybe you did, maybe you didn't. You now have an opportunity to find out what was wrong and if you caused it.
Or someone else will and blame you.

Re: What is the best wrench for removing 1" plug?
and as addendum to the earliest comments on the thred, you really can't get by, in my opinion, without a set of 4 or 8 point sockets. the 8's are easier to come by, e.g. http://www.amazon.com/Sunex-2858-2-Inch-8-Point-13-Piece/dp/B003XIJ82M/ref=sr_1_9?ie=UTF8&qid=1417649071&sr=8-9&keywords="8+point+socket"
I use these things all the time. among other things to drive taps where i don't have room to turn a traditional wing handled tap wrench.
