CSIA EXAM 2026/2027 — CERTIFIED CHIMNEY SWEEP
PRACTICE TEST WITH 200 QUESTIONS
Chimney and venting safety · 200 original four-choice items · Answers and rationales integrated
Disclaimer. This is original study material for education. It is not an official, verified, authenticated, or CSIA
examination, and it does not reproduce examination items. A result on this set does not predict a CSIA score or confer
the Certified Chimney Sweep credential. Keyed choices are printed in readable cyan-blue (#007C8A) rather than pure
cyan (#00FFFF), which is nearly invisible on a white page.
Section 1: Brief Introduction
The Chimney Safety Institute of America awards the Certified Chimney Sweep credential after a
CCS review and a two-part exam taken in one appointment: a one-hour, 100-question closed-
book portion on chimney and venting essentials and NFPA 211, and a 90-minute, 30-question
open-book portion using the candidate’s own International Residential Code. Certification runs
on a three-year cycle, with an annual fee of $249 for the first two years and renewal in the third
year by retesting or by completing the required continuing-education units, and every
candidate signs the CSIA Code of Ethics. This original 200-item set is for study and is not an
official, verified, or CSIA examination.
Section 2: The Complete Exam
Each item has one best answer. The keyed choice is set in bold cyan-blue (#007C8A) because pure
cyan (#00FFFF) disappears on white. A rationale follows every item. This set does not establish a
passing score.
Credential and Examination Framework
Who issues the Certified Chimney Sweep credential, how the two-part exam is built, and what this practice
set is not.
1. What credential does the primary CSIA individual examination award?
A. Certified Sustainable Infrastructure Analyst, issued by a green-building board.
B. A state mechanical license that replaces every local permit.
C. Control System Integrators Association company accreditation for one technician.
D. Certified Chimney Sweep (CCS), issued by the Chimney Safety Institute of
America.
Rationale: CSIA is the Chimney Safety Institute of America, and the individual field credential is
Certified Chimney Sweep. It is not a sustainable-infrastructure analyst certificate, a company
automation audit, or a substitute for a local license.

2. How is the CSIA Certified Chimney Sweep examination structured?
A. A one-hour, 100-question closed-book portion and a 90-minute, 30-question
open-book International Residential Code portion, taken in the same appointment.
B. Two hundred scored items in one hour, all open book.
C. An oral roof evaluation with no written items.
D. Fifty dryer-exhaust questions only.
Rationale: CSIA states that both portions of the CCS exam are taken in one testing
appointment, for about a two-and-a-half-hour session. The closed-book portion draws on
chimney and venting essentials and NFPA 211. The candidate must bring a personal copy of the
IRC for the open-book portion.
3. When does a candidate see the CCS examination result?
A. The score appears when the exam is finished.
B. Only after a 180-day scoring period.
C. Never. CSIA reports only pass or fail by postal mail the next year.
D. Only if the candidate pays a separate grading fee weeks later.
Rationale: CSIA says the score is shown at the end of the examination. A practice-set
percentage is not that score and does not establish the cut score. This set is not the examination
itself.
4. Which statement about the open-book portion is correct?
A. The open-book portion may be taken on a later day.
B. NFPA 70 is the only permitted book.
C. Any internet search is allowed during that portion.
D. The candidate must use a personal copy of the International Residential Code. A
borrowed screen share or a memory of the code is not the permitted reference.
Rationale: CSIA requires the candidate’s own IRC, print or PDF, for the open-book portion.
Both portions are completed in the same appointment. Looking up unrelated material is not the
same as using the required code.
5. How long is the Certified Chimney Sweep cycle, and what fee does CSIA state for the first two
years?
A. A three-year cycle, with an annual payment of $249 due for each of the first two
years and renewal required in the third year.
B. A ten-year cycle with no continuing education.
C. A permanent credential with no fee and no renewal.
D. A one-year cycle with a $15 renewal fee only.
Rationale: CSIA publishes a three-year CCS cycle. The $249 payment covers each of the first
two years, and the credential must be renewed in the third year. A proctoring charge is not the
renewal fee.

6. Which renewal path matches the CSIA continuing-education option that avoids a retest?
A. Earn 48 continuing-education units, including the required minimums in
technical, codes, communication and liability, and health and safety topics.
B. Retake only the dryer-exhaust exam.
C. Sign a new ethics card with no education and no examination.
D. Earn 9 units and skip both the retest and the category rules.
Rationale: CSIA allows renewal by a review and retest, by 9 to 47 units plus a retest, or by 48
units in the stated categories without a retest. The 48-unit path still has category minimums. It
is not an informal promise to keep studying.
7. What must a candidate do about the CSIA Code of Ethics?
A. Sign it only after the first customer complaint.
B. Ignore it because the technical exam is the only requirement.
C. Review it before the exam and sign it at certification. The credential includes a
duty to work honestly and within one’s competence.
D. Replace it with a company slogan.
Rationale: CSIA requires the ethics commitment at certification, not after a dispute. Technical
knowledge does not excuse concealed hazards or work the person is not competent to perform.
The code is CSIA’s document, and this practice item does not reproduce it.
8. A technician finishes the online CCS review and asks whether that review is enough to
guarantee a pass. What is the accurate answer?
A. The review is preparation, not a substitute for studying the manuals, and it is not
the examination.
B. A practice quiz score is the official cut score.
C. Finishing the slides waives both portions of the exam.
D. The 28-day review window is the certification period.
Rationale: CSIA offers academy, one-day, and online review paths, and the online review has a
limited study window. The review itself says it does not replace intense study. Passing this
practice set does not confer the CCS credential.
Combustion, Draft, and Creosote
Why flues draft, why deposits form, and which fuels and burn habits make a chimney dangerous.
Original study material · Not a CSIA examination · Page 3

9. Draft in a residential chimney is best described as what?
A. The thickness of the crown in inches of mortar.
B. The pressure difference that moves flue gas from the appliance to the outdoors,
commonly measured in inches of water column.
C. The color of the flame only.
D. The electrical voltage at the fan proving switch.
Rationale: Draft is a small pressure difference, not a flame color or a masonry dimension. Hot
flue gas is more buoyant than outdoor air, so a sound chimney develops negative pressure
relative to the room. A manometer, not a visual guess, quantifies it.
10. Which change most reliably strengthens natural draft?
A. A shorter chimney and a cold, leaky flue.
B. A larger house exhaust fan with no makeup air.
C. A taller effective flue and a warmer flue-gas column compared with outdoor air.
D. A rain cap sealed tightly against the flue outlet.
Rationale: Stack effect increases with height and with the temperature difference between flue
gas and outdoor air. Leaks, a cold flue, and house depressurization weaken the available draft.
A cap that blocks the outlet can undo an otherwise adequate chimney.
11. A wood stove puffs smoke into the room at startup. Which cause should be checked first?
A. Too much seasoned wood and an oversized flue liner.
B. A cold flue, a blocked cap, or a house that is depressurized. The stove may also
need more combustion air.
C. A spark arrester opening of one-half inch, which always causes puffing.
D. A crown that is too thick.
Rationale: Startup spill often means the flue has not yet established draft, or the house air
pressure is lower than the outdoors. Giving the fire adequate air and checking for blockage
come before any claim that the chimney is simply too tall. A code-size spark screen is not itself a
diagnosis.
12. Creosote forms in a wood-burning flue mainly because what happens?
A. Unburned wood tar condenses on surfaces that are cooler than the flue gas.
B. Seasoned hardwood cannot produce deposits.
C. Complete combustion leaves only a dry mineral film.
D. A 3-2-10 termination chemically creates tar.
Rationale: Creosote is condensed, unburned organic material. Cool flue walls, smoldering fires,
and wet fuel increase it. A correct termination height does not create creosote, and no species
of wood is exempt if the fire is incomplete.
