well for one in Rochester, NY that's what is sold and second i have seen bad pressure reducing valves at the house with water pressure nearly 150psi. In that case the valve need to be replaced and water authority brought in, talk bout a real long cold day. So id rather be on the high side for...

Sounds like you need a manometer to measure gas pressure. If you look closely on the gas valve there two ports with an allen wrench stud keeping them closed. one for inlet pressure and the other outlet pressure. inlet pressure could be between7-13in/wc and outlet on most water heater gas valves...

Is your boiler a high eff with an outdoor sensor. With some boilers, water temp and outdoor temp figure into where the boiler fires and if high is even need for efficiency. For the boiler, it maybe more eff to run on lo fire for 10min than on hi for 5-8min

Have you ever flushed the sediment in the tank that settles to the bottom. Overtime this builds up, acting like an insulator producing luke warm water till enough water is flowing through mixing together allowing for better heat transfer. But agree with above, its a ticking time bomb, its...

Seen this before, this noise is caused by an improper air to fuel mix. you will need screwdriver, co analyzer, and patience cause its in tight spot. Don't quote me on this but I believe number is around 9.8 but can be verified through triangle tube. And don't let them side track you with ignitor...

A little food for thought, if owning a boiler you should purchase a water pressure gauge that reads up to 200psi with 3/4" threads. With this you can verify water pressure in the boiler and see if press/temp gauge is correct, if the pressure reducing valve is working, and verify house pressure...

Some manufactures require that the flue actually have a slight pitch down for condensation to run outside instead of back to boiler since non high eff equip have no drains. I would think vertical is proper, but either pipe term was twisted during assembly and never straightened, or there is a...

Most likely not tstat because you proved the switch. When tstat called for heat the boiler turned on. Prob with boilers is that there are mult parts functioning. Tstat could be fine but how bout the zone valves. what's the press/temp gauge read. you need to know water press when boiler is cold...

did you remember to turn gas valve from pilot to on otherwise no gas feed to burners

I see you've had plenty of responses, and yes all of your problems are resulting from improper sizing at all levels. Remember to have 5ton equipment you need house large enough plus properly sized ducts to accommodate this volume of air. A rough rule of thumb is 1ton of cooling per 1,000sq.ft of...
