CORRECT ANSWERS RATED +
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 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
