Technical Standards and Safety Authority (TSSA) G3 Practice Exam

What can a G.2 Technician do regarding a defective residential automatic gas-fired water heater?

1. advise the user of the appliance that a plumber is required

2. replace the defective residential automatic gas-fired water heater

3. recharge an add-on central air conditioner with refrigerant
