  • MF
Specification Objective

If installed, vent all gas pressure regulators requiring venting to outside the building with code approved rigid pipe

Terminate pipe in a safe location without any thread, coupling, fitting, etc. that would allow a plug to be easily fitted

Vent flammable gasses outside the building

  • SF
  • MH
  • MF
Specification Objective

Seal all gas piping in accordance with manufacturer specifications

Leak free gas piping

  • SF
  • MH
  • MF
Specification Objective

Install a secondary LP safety detector system (e.g., valve, exhaust fan, alarm light) for propane piping installed below grade

Detect accumulation of dangerous levels of propane in areas that are below grade

  • SF
  • MH
  • MF
Specification Objective

If a gas pressure booster is necessary, confirm compatibility with the gas-fired equipment and check low and high gas pressure switches for proper operation

Gas pressure booster is compatible and safe
