False
After boiler repairs are made, installer/service verification of function testing must be completed.
True
Induced draft means that there is a fan on the back end of the system (by the chimney).
True
Contaminated oxygen is not required for the combustion of fuel.
True
Logbooks must be hardbound and have consecutively numbered pages.
True
If a substance has a pH level that is below 7 it is considered to be
Neither neutral nor Basic
The minimum penalty for cheating on the boiler exam is $600
False
A safety relief valve on a low pressure hot water boiler may be set at 160 psig
True
A boiler with very clean water does not require water treatment
False
A low pressure black seal operator is required in a multi-dwelling complex (apartment complex) when the boilers total 4,000,000 btus.
False
Boiler water is treated to remove nitrogen from the water
False
Is a welded repair allowed on the pressure retaining area of a boiler or pressure vessel?
False
The maximum setting allowed on a low pressure steam boiler safety valve is 15 psi.
True
Impurities that increase the density of the boiler water are removed by:
both bottom and surface blowdown
A vent valve should be opened up when:
Both warming up and shutting down the boiler
Soot build-up on heating surfaces
both increases the amount of fuel and blocks heat transfer
Bottom blowdown works best when the boiler is in high fire.
False
A boiler inspector has the right to inspect the boiler without notice.
True
Definition of a boiler dry lay-up: the procedure that is generally used in boilers that are to be out of service for extended periods of time ( 30 Days) where an operator needs to drain, clean and thoroughly dry the inside of a boiler

Return the water to the boiler while the boiler is idle
A boiler with water at a pH level of 7 will be considered alkaline/basic.
False
Why should the gauge glass on a steam boiler be blown down regularly?
to remove dirt and sediment from the glass
A safety relief valve is considered the most important fitting.
True
A low pressure license may be used in two locations so far as the operator has the license In his/her possession.
False
A dirty sight glass in a steam boiler is a violation in the State of NJ.
True
What prevents explosions in a boiler room?
the purge cycle during the sequence of operation and
testing the low-water cut-off and
the BMS
A(n} _________draft fan is located after the furnace.
Induced
A boiler pressure control device (pressuretrol) is not needed to control pressure in a steam boiler.
false
Blowing down is most effective when the steam output is _________
at a low rate
Most low pressure hydronic systems (hot water systems) utilize radiators to supply heat.
True
The following is used to perform a steam boiler function test.
Safety valve
An operator can frame and display a photocopy of his/her boiler license in the boiler room.
False
The maximum pressure setting allowed on a low pressure hydronic system is 170 psig.
False
When oil strainers are cleaned properly, suction readings will be high.
True
The main reason make-up water is added to the boiler is to:
Replenish water that has been lost and to supply enough water to keep the proper amount of steam flowing
In accordance with accepted practice, the type of valve located between the boiler and the safety valve must be a/an:
No valve
NJ BBPVC published an advisory that states that a backflow preventer cannot be used to replace a metal check valve.
True
The primary function of adding make-up water to a system is to:
Replenish water that has been lost and to supply enough water to keep the proper amount of steam flowing
Cast-iron is a material that can be used to build a boiler.
True
