the NFPA 58 test for leakage checks for propane leaks at the _____ portion
of the piping only. - answer exterior
you are required to perform a leak check on a vapor distribution system
immediately after turning on the gas in a new gas system but not after a
system has been restored after an interruption of service. T/F? - answer
False
Which of the following measures the amount of delivered pressure to the
gas appliances with no gas demand to ensure that the regulator will shut
off the flow of propane when the appliances are turned off?
Flow/Pressure/Lock-Up/Leak - answer Lock-Up Test
When conducting an NFPA 54 Pressure Test, what type of gas should you
never use? - answer Propane
, Which test pinpoints a leak found during another test in the vapor
distribution system? - answer Leak Test
what test determines if the regulator and piping system are sized
correctly to handle the btu load of the system?
Flow/Lock-Up/Leak/Pressure - answer Flow Test
Polyethylene (PE) tubing & piping are not permitted for use in the interior
portion of gas systems. T/F - answer True
To verify the appropriate regulators have been selected, you must
consider the inlet & outlet _____. - answer Pressure
Regulator vents must be a minimum of __ ft from any sources of ignition,
appliance, vent. - answer 5 ft
What test on gas piping verifies that the system is " gas tight" or leak
free. Performed before new installations are put into place?
Pressure/Flow/Lock-Up/Leak - answer Pressure Test
What test checks for a propane leak by applying pressure to a system
downstream from the outlet to the appliance? Flow/Leak/Lock-Up/Pressure
- answer Leak Check
What test is on the exterior portion of a piping system to determine if
there are propane leaks? Leakage/Lock-Up/Flow/Pressure - answer Test for
leakage
______ appliances generate higher amounts of flue gases and must be
vented to the outside. ex: water heater - answer Vented
when verifying the installation of vented appliances, what should you
check? - answer - accessible
