COMPREHENSIVE EXAM – NEW VERSION (LATEST UPDATE)
1. A technician is evaluating the propane system in an RV. The appliance regulators need to
receive propane at a safe operating pressure. What is the typical range for low-pressure
appliance regulators in inches of water column (Wc)?
A. 5–6 Wc
B. 10–10.5 Wc
C. 12–13 Wc
D. 15–16 Wc
Answer: B. 10–10.5 Wc
Rationale: Appliance regulators are set to approximately 10–10.5 Wc to ensure the proper
operation of propane-fueled appliances without over-pressurizing.
2. During a propane system inspection, the technician notes that the first-stage regulator
should reduce the high cylinder pressure to a specific value before reaching the second-stage
regulator. What is this first-stage regulated pressure?
1
, Page 2 of 109
A. 5 psi
B. 10 psi
C. 20 psi
D. 30 psi
Answer: B. 10 psi
Rationale: The first-stage regulator reduces cylinder pressure to about 10 psi, which the second
stage further reduces for safe appliance use.
3. Propane cylinders are never filled beyond a certain percentage to allow for expansion. What
is the standard fill limit for propane cylinders?
A. 70%
B. 80%
C. 90%
D. 100%
Answer: B. 80%
Rationale: Propane expands when exposed to heat. Filling only to 80% allows for vapor
expansion and prevents overpressure conditions.
4. A propane tank’s boiling point is critical for understanding system behavior in cold weather.
At what temperature does propane boil under standard conditions?
2
, Page 3 of 109
A. -44°F (-42°C)
B. 0°F (-18°C)
C. 32°F (0°C)
D. 100°F (38°C)
Answer: A. -44°F (-42°C)
Rationale: Propane has a low boiling point of -44°F, which means it vaporizes easily, allowing
gas to flow to appliances.
5. DOT propane cylinders have a service life after which they must be retired. How many years
after manufacture are DOT cylinders required to be taken out of service?
A. 5 years
B. 10 years
C. 15 years
D. 20 years
Answer: B. 10 years
Rationale: DOT cylinders have a 10-year expiration date for safety compliance; they cannot be
used beyond that time.
6. Which of the following is not an appurtenance found on ASME propane tanks permanently
mounted in RVs?
3
, Page 4 of 109
A. Safety relief valve
B. Vapor withdrawal tube
C. Pressure gauge for fuel level
D. Overfill protection device (OPD)
Answer: C. Pressure gauge for fuel level
Rationale: ASME tanks include a vapor withdrawal tube, OPD, sight gauge, and safety relief
valve. They do not use a standard pressure gauge for fuel level.
7. When conducting a propane lock-up pressure test, what is the maximum allowable pressure
reading in inches of water column?
A. 11 Wc
B. 12 Wc
C. 14 Wc
D. 16 Wc
Answer: C. 14 Wc
Rationale: During the lock-up pressure test, the regulator must not exceed 14 Wc, ensuring safe
operation and preventing overpressure conditions.
8. A technician is performing an operating pressure test on an RV propane system. With at least
50% of the appliance load running, the manometer should display approximately:
