MASSACHUSETTS OIL BURNER EXAM 2024 ACTUAL NEW EXAM AND PRACTICE QUESTIONS
EXAM COMPLETE ACCURATE EXAM QUESTIONS WITH DETAILED VERIFIED ANSWERS/ALREADY
GRADED A+
The holes that are provided in the flue pipe for combustion must be: - correct one-between the heating
unit and the draft regulator
When using a pump type smoke tester, ten full strokes are necessary to: - correct one-draw the proper
amount of flue gas past the paper
The fluid in a CO2 tester is good for about how many tests? - correct one-For about 200 tests
In an electric circuit for the wattage to remain the same if the voltage drops, the amperage must: -
correct one-increase
Air heater - correct one-An indirect fired Appliance intended to supply heated air for space Heating and
other purposes but not intended for permanent installation
Air pressure switch - correct one-An electrical switch designed to prove that the proper draft has been
established by the power Venter or burner and allows the burner to operate. It will de-energize the
burner control circuit preventing the burner from operating, if the power venter or burner is not
performing to satisfaction.
Anti flooding device - correct one-A primary safety control that causes the flow of fuel to be shut off
upon a rise in fuel level or upon receiving excess Fuel, and which operates before the Hazardous
discharge of fuel can occur.

temperatures not exceeding 600°F (316°C) and if not larger than 100 cu ft (2.8 m3) not including any
blower equipment and blower compartment.
Medium heat industrial appliance - correct one-Appliances operating at over 50 PSIG (345 kPa) pressure
when such Appliance is larger than 100 cu ft (2.8 m3) in size. Aswell as other medium-heat appliances in
accordance with recognized good practice.

and other furnaces classified as high-heat appliances in accordance with recognized good practice.
Application permit/Certificate of Completion - correct one-A standard form issued for use in all
jurisdictions throughout the Commonwealth.
Approved - correct one-Unless otherwise indicated listed or approved by a nationally recognized testing
Laboratory
Authority having jurisdiction - correct one-The State Fire Marshal or his designee
Boiler - correct one-A closed vessel in which water is heated, steam is generated, steam is superheated,
or any combination thereof, by the application of heat from combustible fuels in a self-contained or
attached furnace
Boiler, High Pressure - correct one-A boiler for generating steam at pressures in excess of 15 psi (103 kPa)
or for heating water to a temperature in excess of 250° F (121°C) or at a pressure in excess of 160 PSI
(1103 kPa)
Boiler hot water supply - correct one-A low pressure hot water boiler having a volume not exceeding 120
gal (454 L) or a heat input exceeding 200,000 BTU per hour (58.6 kW) or an operating temperature
exceeding 200° F (93°C) that provides hot water to be used externally to itself
Boiler, low pressure - correct one-A boiler for generating steam at pressures not in excess of 15 PSIG (103
kPa) or for Furnishing water at a temperature not in excess of 250° F (121°C) pressure's not in excess of
160 PSIG (1103 kPa)
Burner automatically ignited - correct one-A burner equipped so that the main burner fuel may be
turned on and ignited automatically
Burner manually ignited - correct one-A burner equipped so that main burner fuel is used on only by
hand and ignited under supervision
