Question 1

When installing CSST in a structure, what bonding requirement must be met to comply with BGE and code requirements?

Accepted Answer

CSST must be bonded to the electrical grounding system to prevent lightning strike damage

Answer

CSST must be bonded to the building's electrical grounding system because lightning-induced electrical surges can arc through CSST and cause leaks or fires.

Question 2

Which valve type is required as the main shutoff on a new gas service installation entering a residential building?

Accepted Answer

Ball valve or plug valve listed for gas service

Answer

A ball valve or plug valve listed for gas service is required as the main shutoff because it provides a full-bore, quarter-turn shutoff that is reliable and easy to operate.

Question 3

When installing gas piping through a foundation wall, what is required at the penetration point?

Accepted Answer

A sleeve larger than the pipe must be installed to allow for movement and sealing

Answer

A sleeve larger than the pipe must be installed at foundation penetrations to allow for building settlement and to prevent pipe stress while the annular space is sealed.

Question 4

What pressure test is typically used to verify the integrity of new gas piping before placing it in service?

Accepted Answer

An air or nitrogen pressure test at 1.5 times the maximum allowable operating pressure

Answer

New gas piping must be pressure-tested with air or inert gas (not gas) at 1.5 times the MAOP to verify integrity before being placed in service.

Question 5

When installing gas piping near electrical wiring, what minimum separation should be maintained?

Accepted Answer
