Burnham boiler question

the manual says to increase the tstat setting by ~0.1 amp to avoid short cycling. how many F degrees on the tstat is equivalent to 0.1 amp in this table?

Thanks.

I was not concerning the pipe materials.

I was asking weather the joints of he pipes with elbows, and the pipes with the T (in that U shape assembly) are lead hubbed or tapped threaded. it's all hubbed, or at least hubbed where the two elbows tie to the two horizontal pipes (the other 5 connections can be threaded), right?

I have had some experience with diesel fuel system, I'm just curious about the domestic water plumbing where things are different.

Thanks for the reminder. I should blow all water out asap. I thought to place some temp sensors and keep monitoring the inside temp. The gas servicer has not filed the working permit yet. I complained to the city, hopefully Nationalgrid will call me about a timeline next week. I visit my new place every weekend. The plan regarding the steam boiler is to measure the probe this weekend, and bring my wrenches there in the following visit, I will also take a photos.

i'm going to use rectorseal 5 when reassembling.

when you say wrong, do you mean all 7 connections (each elbow has 2, T has 3) can be tapped threads?

i remember the system supply steam pipes are all 2" or 3" cast iron ones, on my steamer.

now that you highlighted it, i recall the manual has a paragraph that disapproves using cooper for steam piping, mainly due to high thermal expansion and heat loss.

I have to admit I laughed. but I was asking how to set the steamer in vacation mode that provides minimum protection from freezing while avoids short cycling, it still has no answer either. this is very legit question, rather than a junk mail.

I thought the gas company just need to restore the gas line to its original condition before it was capped, but the company's clerk just emailed me a gas load form that I have to fill and sign.

in its "terms and conditions" part, it says -

"In the event that the equipment identified on the front of this agreement (i.e. the table attached) is not installed and in use within three months (Existing Homes) or six months (New Construction) of the date of installation of the service line, the Applicant agrees to pay National Grid the actual cost of installing and disconnecting the gas service line plus the actual cost of any required main work minus any payments already received "

the gas equipment include the steam boiler, hot water heater, gas dryer, range/oven. How to find the min and max inlet pressure, and BTU input for each? what does Firm/Duel Fuel Rate mean?

I found this stuff on Amazon. Where do you add it?

When the lwco is removed, I can transfer some in from the tapping. But after the water is filled up, there is not a port for adding this cleaner.

This is the return piping ends where the rust flakes and crud settle. Other than the plugs A and B, I haven't found any shut off valves that isolate the return sections for pressure cleaning. How to clean out the crud from the inside of the return piping?

they are the steam return piping at the back of the boiler

roughly this area

Thanks. Is there corrosion concern in coupling a brass valve to a steel fitting? My search returns a "dielectric nipple", is this often used in the trades?

Thanks for confirming.

Right under the so called hardford loop there is also a stand pipe cut short and capped that I labeled as C. What was this piping used for?

This is the form I sent to the clerk. She told me today -

"After reviewing the load letter, the BTU load amounts are too large for the existing pipe to carry, which means a new service will be required"

The existing pipe as I heard on the phone is 1". Is 315,100 btuh really too large for 1" pipe to handle, or did I fill wrong information?
