Oil burner test Questions and Graded Answers.
What is the largest exposed tank allowed in a building without a permit - 660 g
What is tank approval - UL 80 UL 142
A supply tank shall be securely supported by ridged, non-combustible supports to prevent
settling, sliding or lifting. true or false - True
What is the largest amount of oil that can be stored with exposed tanks? - 1320 g
What is the closest distance a supply tank can be to the burner - 5 ft
What is the gauge of a 275 g above ground tank - 12 gauge
The maximum amount of fuel may be delivered without a permit to store in effect provided that
application has been made in accordance with code. true or false - True
Vent pipe for a 500 g tank should be - 1 1/4"
A supply tank may be supported by any ridge support. true or false - False
Stack switch relays can no longer be used in installations or replacement because - Their
lock-out time is no longer the code requirement
An oil safety valve should be used when burner pump is lifting oil. True or false - False
, On a warm air furnace, the blower comes off and on in short cycles because - The fan
on/off differential is less than 40°F
What could cause a steam boiler to flood - Leaky tank less coil
Having to put water in a steam boiler once or twice a week is caused by - Weak return
line, radiator vents leaking, boiler sprung a leak
Some radiators on a steam system do not heat up because - The radiator vents are clogged
On a hot water boiler the pressure is 30psi and the relief valve is open because - Leaky
tankless coil, bad pressure reducing valve, perforated tankless bladder
Some forced hot-water radiators are not heating because - Vent is clogged, radiators are
air bound, radiator valves clogged shut
A cad-cell primary control can lock-out safety because - Cad-cell is dirty, Cad-cell is
faulty, The cad-cell is not sensing flame
On a no heat call, a cad-cell primary control fired when TT is jumped out because - The
thermostat or thermostat wired are no good
In-step means - The primary control start circuit is closed
On a no heat call on a hot water system, the oil burner is off on high-limit, but the circulator is
not running because - The reverse is open, circulator motor burnt out, switching relay is
faulty
The burner operates but there is no combustion because - There is too much air
