Michigan Boiler Installer 2B Practice
Exam
,Question 1: A commercial boiler installation operation in Wayne County, Michigan
requires statutory and technical compliance under 2016 PA 407 and ASME codes. A
licensed Class 2B boiler installer in Wayne County, Michigan is contracted to install
a high-pressure steam power boiler rated at 150 psi. Under Michigan Skilled Trades
Regulation Act (2016 PA 407) and Boiler Rules, what scope of work is authorized
under a Class 2B installer license?
A. Installation of miniature steam boilers only, limited to 15 psi maximum operating
pressure
B. Installation of low and high pressure boilers of any capacity and pressure up to
maximum design limits permitted by ASME Section I and IV
C. Repair of nuclear power vessel components exclusively
D. Installation of low pressure hot water heating boilers only, not exceeding 160 psi or
250°F
Answer: B — Installation of low and high pressure boilers of any capacity and
pressure up to maximum design limits permitted by ASME Section I and IV
Rationale: A Michigan Class 2B boiler installer license authorizes the installation of
low and high pressure boilers without limit on pressure or capacity under 2016 PA
407.
Question 2: According to Michigan Boiler Act (2016 PA 407), Michigan Boiler
Administrative Rules (R 408.4001), ASME Section I, ASME CSD-1, and NBIC
standards: According to Michigan Boiler Administrative Rules, prior to starting any
installation, alteration, or repair of a regulated boiler in Michigan, what
administrative requirement must be completed?
A. A permit to install must be issued by the Michigan Department of Licensing and
Regulatory Affairs (LARA) prior to commencing work
B. No permit is required if the boiler is purchased from an authorized local distributor
C. A verbal notification to the local fire chief within 30 days post-installation is sufficient
D. A permit is required only after the boiler has been operating for 60 consecutive days
Answer: A — A permit to install must be issued by the Michigan Department of
Licensing and Regulatory Affairs (LARA) prior to commencing work
Rationale: Michigan Boiler Rules state that no person shall install, alter, or repair a
boiler without first obtaining a permit from LARA's Bureau of Construction Codes.
,Question 3: A commercial boiler installation operation in Macomb County,
Michigan requires statutory and technical compliance under 2016 PA 407 and
ASME codes. During the installation of an ASME Section I high-pressure steam
boiler in Macomb County operating at 250 psig, the installer connects the main
steam stop valve. What requirement applies to the main steam discharge valve
when two or more boilers are connected to a common header?
A. A single gate valve without any drain connection
B. Two stop valves with an ample free-blow drain between them, one of which must be
an automatic non-return valve located closest to the boiler
C. A pressure reducing valve bypassing the main header
D. A swing check valve with no manual isolation capability
Answer: B — Two stop valves with an ample free-blow drain between them, one of
which must be an automatic non-return valve located closest to the boiler
Rationale: ASME Section I (PG-58.3.1) mandates two stop valves with an
intermediate free-blow drain between them for boilers connected to a common
header, with the valve closest to the boiler being an automatic non-return valve.
Question 4: According to Michigan Boiler Act (2016 PA 407), Michigan Boiler
Administrative Rules (R 408.4001), ASME Section I, ASME CSD-1, and NBIC
standards: Under ASME CSD-1 standards for automatically fired steam boilers,
what is the mandatory requirement for the secondary low-water fuel cutoff device?
A. Only one automatic-reset low-water cutoff is permitted
B. A low-water cutoff is optional if a high-pressure limit switch is installed
C. Two low-water cutoffs are required, but both must automatically reset as soon as
water level returns
D. Two low-water fuel cutoffs are required; the secondary cutoff must be a
manual-reset type that prevents automatic restarting of the burner
Answer: D — Two low-water fuel cutoffs are required; the secondary cutoff must be
a manual-reset type that prevents automatic restarting of the burner
Rationale: ASME CSD-1 CW-210 requires automatically fired steam boilers to have
two low-water fuel cutoffs; the lower (secondary) cutoff must require a manual
reset.
, Question 5: A commercial boiler installation operation in Genesee County,
Michigan requires statutory and technical compliance under 2016 PA 407 and
ASME codes. An installer in Genesee County mounts a safety valve on an ASME
Section I steam boiler. Under ASME Section I PG-71, how must the safety valve be
connected to the boiler shell or drum?
A. The safety valve must be connected directly to an independent nozzle without any
intervening shutoff valves or restrictive fittings
B. A manual isolation gate valve must be placed prior to the safety valve for
maintenance safety
C. Safety valves must always be mounted horizontally on the main steam line after the
main stop valve
D. The inlet piping diameter may be reduced to one-half of the safety valve inlet size to
increase velocity
Answer: A — The safety valve must be connected directly to an independent nozzle
without any intervening shutoff valves or restrictive fittings
Rationale: ASME Section I PG-71.2 explicitly prohibits any intervening shutoff valve
between the boiler and its safety valve, and requires direct, upright mounting to an
independent nozzle.
Question 6: According to Michigan Boiler Act (2016 PA 407), Michigan Boiler
Administrative Rules (R 408.4001), ASME Section I, ASME CSD-1, and NBIC
standards: What is the standard hydrostatic test pressure multiplier required by
ASME Section I for a newly installed or majorly repaired power boiler prior to initial
operation?
A. 0.75 times the MAWP for a minimum of 10 minutes
B. 2.0 times the MAWP with steam heating applied during testing
C. 1.5 times the maximum allowable working pressure (MAWP), maintaining water
temperature between 70°F and 120°F
D. 1.0 times the operating pressure with water near freezing (35°F)
Answer: C — 1.5 times the maximum allowable working pressure (MAWP),
maintaining water temperature between 70°F and 120°F
Rationale: ASME Section I PG-93 requires hydrostatic testing at 1.5 times MAWP.
Water temperature must be held between 70°F and 120°F to prevent brittle fracture.
