Pass the Red Seal Gasfitter - Class B Exam

The Red Seal Gasfitter - Class B exam has 100 multiple-choice questions, a 4-hour time limit and a 70% pass mark. Questions are spread across the 7 major work activities of the Red Seal Occupational Standard: Services fuel systems, appliances and ancillary equipment — 18%; Tests and commissions fuel systems, appliances and ancillary equipment — 16%; Installs venting and air supply systems — 15%; Installs controls and electrical systems — 15%; Installs and converts fuel systems, appliances and ancillary equipment — 15%; Installs fuel piping and tubing systems — 14%; Performs common occupational skills — 7%. A formula sheet and an acronym list are provided at the exam. Weight your study time to match: servicing, testing and commissioning together carry 34% of the marks.

Most questions put you on a job: size a gas line or a vent, choose the air-supply openings for an appliance room, set up and read a pressure test, purge a line, follow a flame-safeguard sequence, read a combustion analysis, or find the fault on an appliance that will not stay lit. The rules behind the answers come from CSA B149.1, the Natural gas and propane installation code. Red Seal sets the mix at 25-35% knowledge and recall, 50-60% procedural and application, and 10-20% critical thinking.

Provincial medians include $42.27/hr in Alberta, $39.82/hr in British Columbia, $35.24/hr in New Brunswick and $32.00/hr in Manitoba. The figures cover every gas fitter in the NOC group, Class A and Class B. Source: Job Bank Canada wage data.

Certification is compulsory in Alberta, British Columbia and Quebec: there you must be a registered apprentice or hold a certificate to do the work. In Manitoba, New Brunswick, Newfoundland and Labrador, Nova Scotia, Prince Edward Island, Yukon, the Northwest Territories and Nunavut, trade certification is voluntary, but gas work is still regulated, so check with the provincial or territorial gas safety authority before you work on gas. These 11 provinces and territories offer the Red Seal for this trade, and the endorsement lets you work in any of them. Ontario and Saskatchewan do not offer the Red Seal for Gasfitter - Class B.

Every question is multiple choice with four options and one correct answer, as on the real exam, and every one is tagged to the exam's major work activities and tasks. The bank keeps the exam's mix of question types, about 30% knowledge and recall, 55% procedural and application and 15% critical thinking, and about 16% of the questions give you a drawing to work from: a piping layout, a vent run, a wiring diagram or a set of test readings. Code questions are checked against the text of CSA B149.1:25.

The questions are written to CSA B149.1:25, the 2025 edition of the Natural gas and propane installation code, and to the current Red Seal Occupational Standard for the trade. We perform a comprehensive audit and update of our materials once a year to keep every question aligned with the latest standard and any shifts in exam structure.
