Massachusetts Oil Burner Study
guide-Latest Update 2024-
Guaranteed Pass
What is the voltage found at the TT terminals - -24 volts
-What are the 8 steps of a no heat call - -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 - -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.
- -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 - -The stack relay is operating correctly
-What is normal pump pressure - -100 PSI
-How is combustion achieved - -Atomization, air, ignition.
-What is primary air and secondary air - -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 - -It shall be secured attached to
a non-combustible supports
-What is the wire gauge use an oil burner circuits - -14 gauge 15 amp
fuse
-How is an oil burner wired - -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 - -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 - -the ignition Transformer drops out of the
circuit once a flame is established
-What are the elements are found in fuel oil number 2 - -Carbon
hydrogen oxygen and hydrocarbons
-What is a BTU - -A British thermal unit is the amount of heat needed to
raise one pound of water 1 degree Fahrenheit
-How many BTUs are in one gallon number 2 fuel oil - -140,000 BTUs
-What determines the gallons per hour of a nozzle - -Manufacturer ,the
bore size, pump pressure or Orphus
-What is a series circuit - -an electrical or piping circuit where all of the
current or fluid flows through the entire circuit
-What is a degree day - -The average temp for the day - 65
-What is the flash point of number 2 fuel oil - -115 degrees Fahrenheit
-When does the law require a combustion efficiency test - -During
installation and maintenance
-What controller shuts off the oil burner in the event of excessive
temperature in the appliance - -The high limit switch
-What are the three functions of an oil pump - -1- filters 2- pressurizes
3- pumps fuel to the burner
-How is an oil burner circuit wired - -In series on its own circuit
-How is oil flow adjusted in a rotary burner - -Constant level and
metering valve
-What does InStep mean - -The stack relay is operating properly
-How is combustion achieved - -Atomization ,air ,ignition.
-What is the minimum size oil line for residential burners - -3/8 inch
-How is safety timing checked on a stack relay switch - -Remove the
stack relay from the duck and let it run .it should shut off in 45 seconds.
-What is the safety lockout time on Burner firing under 3 gallons per
hour - -45 seconds
-What control devices are found on gravity feed burners - -Constant
level valve
