RVTI Review PDI Propane

When inspecting propane containers, defects include which of the following?

(Choose all that apply.)

• rust

• heat damage

• dents

• expired date

• incorrect grade bolts

When completing the PDI for inspecting propane containers, what is the correct order for the inspection?

• Correctly identify recommendation for container

• Correctly identify defects in the container

• Correctly identify corrective action

• Use appropriate PPE including safety glasses and gloves

Place the steps in order for the correct technique when measuring the dent depth and width of a propane container.

• Refer to the chart for propane tank dents

• Use a straight edge to measure the diameter of the dent

• Place a straight edge across the dent

• Make a recommendation

• Use a ruler or tape measure to measure the distance from the bottom of the dent to the bottom of the crossing of the straight edge

When should a technician perform the four propane system procedures?

(Choose all that apply.)

• during a typical PDI

• when troubleshooting and diagnosing appliance malfunctions

• after disconnecting the propane system to replace any component

• when in doubt

The purpose of the RV propane testing system is o determine, with ​ (a)   accuracy, the RV propane delivery system is ​ (b)   and that the ​ (c)   is operating properly.

According to the RVIA Propane Textbook, lockup pressure...

(Choose all that apply.)

• is defined as the pressure required to press against the diaphragm and overcome the spring force so the valve closes and no propane flows through the regulator

• is defined as the force required to press against the diaphragm and remove the spring force so the valve opens and propane flows through the regulator

• is a direct result of the regulator operating pressure adjustment and the condition of the regulator

• cannot be adjusted to fit with the operating parameters of the regulator lockup requirements

Place the following first 5 steps for the Operating Pressure Test in the correct order.

• Attach the propane test device between the outlet of the regulator and the remainder of the system

• Disconnect the low pressure hose from the outlet of the regulator, or locate the nearest flared connection at or near the regulator

• Turn off all appliances and pilot lights and the service valve on the propane container

• Measure and record the air temperature and the temperature of the gas piping system at the time of the test

• Connect the manometer hose to the barbed fitting on the test device, slowly open the service valve fully on the container

During the Timed Pressure Test, you should reduce the measured pressure on the manometer to approximately ​ (a)   w.c. inches, then turn off the orifice fitting valve and wait ​ (b)   minutes
