MASSACHUSETTS OIL BURNER STUDY GUIDE WELL REVISED #19
What is the voltage found at the TT terminals - correct answer 24 volts
What are the 8 steps of a no heat call - correct answer 1 talk to customer 2 check tt.3
check to make sure an emergency switch is on 4check to make sure there is oil in the
tank 5 check to make sure the main power going to the unit is on six check to make
sure that tank shut off valve is open 7 know whether the tank is located above or below
the burner I know the type and style of the system that is being used on a one or two
pipe system
What is a cad cell - correct answer A device containing condominium sulfide used to
prove the flame in oil burner furnace
How much air is needed to burn a gallon of number 2 fuel oil and why. - correct answer
In 2015 most oil burners are set up to burn with approximately 50% excess air because
it would be dangerous to set up a burner for exactly the correct amount of air
What is the term instep mean - correct answer The stack relay is operating correctly
What is normal pump pressure - correct answer 100 PSI
How is combustion achieved - correct answer Atomization, air, ignition.
What is primary air and secondary air - correct answer Primary air, air that is introduced
to a furnace burner before the combustion process has taken place. Secondary air, air
that is introduced to the furnace after combustion has taken place and that supports
combustion
How should an oil tank be supported - correct answer It shall be secured attached to a
non-combustible supports
What is the wire gauge use an oil burner circuits - correct answer 14 gauge 15 amp fuse
How is an oil burner wired - correct answer Shall be wired on its own circuit. All
protective control and emergency devices shall be series connected in the grounded
line conductors. All the electrical wiring shall be in accordance with 527 CMR 12.00
Massachusetts electrical code
What size vent pipe is required with a 2 inch fill pipe - correct answer A fill pipe shall not
be greater than the vent pipe. The minimum the fill pipe in the state of Massachusetts is
one and one quarter inch.
Explain interrupted ignition - correct answer the ignition Transformer drops out of the
circuit once a flame is established
, What are the elements are found in fuel oil number 2 - correct answer Carbon hydrogen
oxygen and hydrocarbons

What determines the gallons per hour of a nozzle - correct answer Manufacturer ,the
bore size, pump pressure or Orphus
What is a series circuit - correct answer an electrical or piping circuit where all of the
current or fluid flows through the entire circuit
What is a degree day - correct answer The average temp for the day - 65
What is the flash point of number 2 fuel oil - correct answer 115 degrees Fahrenheit
When does the law require a combustion efficiency test - correct answer During
installation and maintenance
What controller shuts off the oil burner in the event of excessive temperature in the
appliance - correct answer The high limit switch
What are the three functions of an oil pump - correct answer 1- filters 2- pressurizes 3-
pumps fuel to the burner
How is an oil burner circuit wired - correct answer In series on its own circuit
How is oil flow adjusted in a rotary burner - correct answer Constant level and metering
valve
What does instep mean - correct answer The stack relay is operating properly
How is combustion achieved - correct answer Atomization ,air ,ignition.
What is the minimum size oil line for residential burners - correct answer 3/8 inch
How is safety timing checked on a stack relay switch - correct answer Remove the stack
relay from the duck and let it run .it should shut off in 45 seconds.
