how should an oil tank be supported - -Ridgid non-combustible supports
to prevent settling, sliding, or lifting
-what is the wire gauge used on oil burner circuits - -14 gauge minimum
-how is an oil burner wired - -oil burners are wired intermittent or
interrupted
-what does intermittent or interrupted mean - -intermittent -
Transformer stays on throughout the burner firing cycle
interrupted - Transformer drops out after flame established

-what are the elements found in fuel oil - -85% carbon
15% hydrogen
-what is fuel oil - -a hydrocarbon
-how must fuel oil be prepared for combustion - -it must be atomized or
vaporized, and mixed with air

to raise 1 lb of water, 1° Fahrenheit
-how many BTUs are there in a gallon of number 2 fuel - -140000
-what determines the GPH of a nozzle - -the orifice
-what is a degree day - -65 degrees Fahrenheit minus the daily average
temperature
-can materials other than steel be used in fuel oil tanks - -yes, is
approved
-what does the word approved mean - -accepted by the Marshall, or by
a laboratory, which is by the Marshall
, -when is a combustion efficiency test required by law - -after
installations and alterations
-what control shuts off the oil burner in the event of excessive heat
temperature in the appliance - -the high limit
-name three functions of an oil pump - -pick up, pressurize, and strain
oil
-how is oil flow adjusted in a rotary burner - -by the constant level valve
-how is safety timing checked on a stack switch - -remove the stack
switch from its holder or disconnect Terminal 3, fire the control and time
it's lockout
-what is safety lockout timing firing under 3 GPH - -45 seconds
-how should a stack control be mounted according to code - -not rigidly
mounted
-why should stack switch not be rigidly mounted - -so it can be easily
removed for cleaning and inspection, without disturbing any wiring
-what safety devices are found on a gravity burner - -a constant level
valve, and a solenoid valve
-when is a tank vent pipe required - -on all tanks
-what must be done after an installation has been completed - -a
certificate of completion must be submitted
-where are certificates of completion submitted - -local fire department
-what is the time limit for submitting a certificate of completion - -72
hours, excluding weekends and holidays
-what is on a certificate of completion - -Name of burner
Approval number issued by Marshall
Grade of fuel oil used
Size of tank in gallons
Any special requirements that pertain to the installation
Assurance of compliance with regulations
Assurance that proper maintenance instructions have been left with the
owner or occupant
Name and address of the owner or occupant of the premises where the
installation or alteration was made
Results of combustion efficiency test and nozzle size
-what kind of joints are used on tank installations - -swing joints
