Nice stuff ! My freands building got yelled at by the EPA they need to change out there number 6 oil boilers to number 4 or number 2 soon. But thats what number 6 does when the boiler first starts up you get a crap load of black smoke out the chimny. Its normel for a number 6 oil boiler but they dont need to change intill 2015 this is something all of nyc is doing soon. Did you know the black smoke stays around for 5 to 10 min after coming out of the chimny.

@skaha77 ....dear Skaha77, it was really kind from you to inform me about these courses...and it would be amazing !!!! but I leave in Italy ( I'm italian...)....I watched on discovery channel and national geographic channel a lot of documentaries about Alberta and , generally, about Canada ( like " comment c'est fait ") ...great country!! kisses and thank you !!!

@domyaska There is a 30-32 lecture Correspondance course available from Southern Alberta Institute of Technology in Calgary Alberta. If I remember right (It's been 30 years) , the address is 1625 16th Ave North West... google it and take a look at it. Power Engineering, 4th class course. It is pretty much what every Steam Engineer in Western Canada does to get their certification. You can do it in 4 months if you spend 45 mins a day at it. If you know Algebra and Trig, it will come a lot easier

I could be mistakin but I am pretty sure it has to do with different evaporator curcuits.
1 metering device per evaporator circuit per stage.

How do the pressure sensors that are shaped like little disks on gas furnaces work. And in a gas valve, is it a servo motor or a solenoid that opens the valves.

A solenoid opens gas valves.
Without looking at the pressure sensors it's kind of hard to give you an answer as to what it is controlling as every furnace is different.

Do You Know how the pressure sensors work?
25HNA6 3 years ago
If you are referring to the pressure switch for the inducer fan it's to verify that their is airflow being drawn through the heat exchanger to prevent the flames from rolling out of the heat exchanger.
It's a safety switch more or less
