Massachusetts oil burner study guide
6 oil burners have been set up in a large room that's of tight production and which need to be
saved closed always there's decidedly not enough combustion air for correct burner operation
there burner sizes are 1.35 gallons per hour below those conditions what's the minimum free
area of an opening connecting to the outdoors which should be furnished - ANS-567 inch by
way of 2 inch vent going to outside
A combustion efficiency take a look at consists of measurements of - ANS-Stack temperature
smoke test and extra of air
A fuel deaerator - ANS-eliminates the need for a go back line back to the tank
a layer of Ash 1/sixteen inch thick will boom gasoline intake by means of - ANS-4%
A unmarried desk bound conductor in the flux of a everlasting magnet will - ANS-result in a
contemporary glide.
A steam pigtail ought to continually be established between the pressuretrol and the boiler too -
ANS-To Place a water seal among the boiler and the strain troll.
About 21% of air is made from - ANS-Oxygen
According to code whilst is a low water reduce off required on a steam boiler - ANS-Steam
boilers and hot water boilers above 400000 BTUs
According to code whilst is a low water cut off required on a water boiler - ANS-Always
Advantage of PSC Motors over conventional break up phase Motors is they - ANS-Are
protected by using an overload transfer
All petroleum products are chemicals of - ANS-Hydrogen and carbon
An advantage of flame retention burner is - ANS-The excessive static pressure permits boilers
and furnaces with tighter extra efficient warmness exchanger passages
Are compression fittings allowed on oil traces - ANS-No
Before the usage of an electronic analyzer you have to - ANS-Performers smoke test to make
certain you are bringing at zero to trace of smoke
, clean is a great insulator at one hundred twenty volts however a very good conductor at ten
thousand volts - ANS-Air
Can a series 10 .Three cord thermostat be used with a 2-cord control? Provide an explanation
for. - ANS-Yes by using leaping out the floor
Can a sequence 80 dryer thermostat be wired into a three-cord control - ANS-No
Can an overflow pipe from the auxiliary tank have a valve or obstruction - ANS-No
Can stack switches be used as a primary control - ANS-Yes
Can Teflon tape be used on oil line connections - ANS-No
Can two deliver tanks be provided with only one fill pipe and vent pipe - ANS-Yes
Compared to wet kits virtual electronic conversion kits units are - ANS-Are faster and can create
a broadcast file
Dirt & Lint constructed up within the bevel of the burner fan blades will - ANS-Reduce the
amount of combustion air
Electrical modern the quantity of strength flowing in a circuit is measured in - ANS-Amps
Energizing the ignition circuit during the entire burn cycle - ANS-Significantly reduces ignition
component existence
Excessive draft drop thru the heat exchanger indicates - ANS-Heavy set and scale deposits
inside the warmth exchanger
Explain how a burner ought to be piped while the deliver tank is placed beneath the burner -
ANS-2. Pipe dual stage with a skip plug
Explain interrupted ignition - ANS-the ignition Transformer drops out of the circuit once a flame
is installed
Explain extraordinary forms of differentials utilized by thermostat - ANS-In heating anticipates
warmth leftover.In cold turns on compressor early
How are number one controls wired - ANS-L Black L2 white Terminal 3 is going to the burner
motor Terminal 4 is going to interrupted ignition all must be bendy
How excessive on the wall need to thermostat be set up - ANS-5 feet from the floor
