The main function of the primary control is: - -Locking out on safety in
the event of flame failure
-Power must be provided to an electric blower control board on
terminals: - -L1 and L2
-Once a PSC motor starts - -The centrifugal switch turns off the
electricity to the capacitor and the start windings
-Materials who's electrons are so loosely bound that they can be
persuaded to move with very little pressure allowing electricity to flow
are called - -Conductors
-Oil burners can make CO even when no smoke is present - -True
-Corrosion in the flu pipe may occur if - -Flue gas temperature is below
the dewpoint and sulfur oxide's combine with water
-To avoid condensing and the flu pipe and oil fired appliance should
have a minimum growth stock temperature of - -350°F

holding a certificate as an oil burner technician must hold current
apprentice certificates issued by Department of fire services - -True

-Fuel return piping from an appliance shall - -Enter the top of the tank
-Delayed ignition may be caused by - -Unvented pressure regulator
-Installation of oil safety valves and oil pressure reducing valve - -
Reduces the chance of a return line leak
-What is an installation - -Complete and ready for operation of any oil
burning appliance

Ignition component life
, -Fuel can be transferred from a tank to an appliance by pressurizing the
tank - -False
-What device must be equipped with an air proving switch - -Both, draft
inducers and power-venters
-What is a safety control - -Any control used to prevent unsafe
operation of the controlled equipment
-A non-resident steam or hot water boiler having a minimum safety
relief valve capacity over 200,000 BTU/hr requires certificate of
inspection from the department of fire services - -Prior to the initial
firing, every 3 years after
-What is the closest distance a supply tank can be to the burner - -5
feet
-Doing a combustion pretest on and oil burning appliance will not tell
you anything this is why they generally are performed - -False
-What is the minimum oil supply line size for a residential system - -3/8
inch
-A cad cell primary control can lock out safety because - -All of the
above- dirty, faulty, not sensing flame
-As heating oil gets colder it's viscosity thickens: - -Increase
-The purpose of the oil burner nozzle is to: - -Atomize, pattern and
meter the oil
-The primary control must be capable of - -All of the above
-A decrease in CO2 with an increase in excess air will give a drop in
stack temperature - -True
-Minimum net stack temperature of above 350°F must be maintained - -
To avoid condensation and maintain draft
-The primary control must be capable of reacting to - -The presence or
absence of flame
-The two principal combustible elements in number two fuel oil are
nitrogen and carbon - -False
-If a stack type controller fails you must - -Replace it with an approved
type controller
-When wiring multiple circulators they should be wired in - -Parallel
