This part maintain constant water temperature and protects the boiler from excessive temperatures.
Aquastat
must be changed when converting gas type
Spuds (orifices)
changes amount of voltage
Transformer
used on wires to remove protective layer to expose metal.
wire strippers
Horton heard a?
who
This part isolate the space being heated by stopping the flow of water to it.
zone valve
blends the air and gas
Burner
reads in DC micro amps, cycles start up if gas does not ignite
flame sensor
This tool tells me amperage, voltage, and resistance
multi-meter
How did Georg Simon Ohm test his theory of OHM's law
by touching the end of wires of different size and materials to see how their resistance affected the electric current
This part moves through boiler system until the demand for heat is satisfied.
circulator pump
Heat exchanger
stores voltage to burst voltage out to a motor.
capacitor
this tool can be used on gas valve and duct work.
manometer
what does a fox say
gering-ding-ding-ding-dingeringeding!
communicates with system to tell system when come on.
Thermostat
only needed in a 90% furnace and is connected to secondary heat exchanger.
collector box
brain of the system, some would call it a city of relays, capacitors, semiconductors, and resistors.
control board
used to force call, can be used on most units but does not work well with some of the smart unit.
jumper wires
Riddle time
I'm
second to begin, first to end, and nowhere to start
who am I.....
The letter E
air filled tank that allows excess pressure of water to go somewhere in a closed system
(is required on a closed loop system)
Expansion tank
must be sealed and guides the CO out of unit
Flue
with a bi-metal will protect unit from over heating
limit safety switch
can be used to clean certain electrical parts on a unit, this is not what it was intended for. It something every tech working should get.
