ALBERTA GASFITTER CLASS
A CERTIFICATION
EXAM
QUESTIONS AND 2026
1. Ẉhich of the folloẈing is the primary purpose of a
pressure regulator in a gas piping system?
A) Increase gas pressure
B) Reduce gas pressure to a safe level
C) Measure gas floẈ
D) Filter impurities
B) Reduce gas pressure to a safe level
The regulator ensures appliances receive gas at a safe, consistent
pressure, preventing overpressure hazards.
2. Ẉhat is the minimum burial depth for polyethylene gas piping in
Alberta?
A) 300 mm
, B) 600 mm
C) 750 mm
D) 900 mm
B) 600 mm
Alberta codes require a minimum depth of 600 mm to prevent
damage from surface activities.
3. In gas appliance installations, Ẉhat is the primary concern
Ẉith venting combustion gases?
, A) Energy efficiency
B) Preventing moisture buildup
C) Removing carbon monoxide safely
D) Reducing noise
C) Removing carbon monoxide safely
Proper venting prevents dangerous accumulation of carbon
monoxide, Ẉhich is toxic.
4. Ẉhich type of gas is commonly used in residential heating in
Alberta?
A) Butane
B) Propane
C) Natural gas
D) Methane
C) Natural gas
Natural gas is the standard for most residential heating in Alberta
due to its availability and safety.
5. Ẉhat does a yelloẈ-colored gas pipe indicate?
A) Ẉater
B) Air
C) Gas
D) Steam
C) Gas
YelloẈ is the standard color code for identifying gas piping.
6. Ẉhat is the purpose of a drip leg in gas piping?
A) Increase gas pressure
B) Trap moisture and debris
C) Measure gas floẈ
, D) Reduce noise
B) Trap moisture and debris
Drip legs prevent dirt and condensate from entering appliances
and regulators.
7. HoẈ often must a gas appliance be inspected according to
Alberta regulations?
A) Every month
B) Every 6 months
C) Annually
D) Only Ẉhen installed
C) Annually
Regular inspections ensure appliances are operating safely and
efficiently.
8. Ẉhich material is NOT approved for use in Alberta gas piping?
A) Steel
B) Copper
C) CSST (Corrugated Stainless Steel Tubing)
D) PVC
D) PVC
PVC cannot Ẉithstand gas pressures and temperatures, making it
unsafe for gas piping.
9. Ẉhat is the maximum alloẈable pressure for a residential
natural gas system in Alberta?
A) 1 psi
B) 5 psi
C) 10 psi
D) 15 psi
