Description

Several reasons to cause the failure of gas regulator

Instructions on gas pressure regulatorInstructions on gas pressure regulator

Specifications

Gas inlet & out size is 3/4"-FNPT. Please use the 3/4"-MNPT to connect the regulator.

For natural gas appliances use only.

Gas inlet pressure is 3/4 psi or 3,485 pa. Out let pressure is 4" WC or 1,750 pa (factory setting), adjustable from 3 to 6" WC.

  • Maximum flow capacity is 150,000 BTU/Hr.

Notes

  • Make sure gas flow through the regulator is the same direction as the flow arrow on the body. Inlet & outlet connection are clearly marked on the regulator body.
  • Too cold or too hot ambient temperature will affect the spring or diaphragm, and then affect the performance of regulator.
  • If debris or dirt found inside affects the performance of regulator, please do not try to losen the screws to fix and repair it, or not, there will be gas leakage.

Installation tips

Installation tipsInstallation tips

  • Please install this gas pressure regulator comply with the gas flow direction.
  • Please do not install this gas pressure regulator too close or too far from the appliances.
  • Please keep in mind that, the output pressure setting is different between natural gas source and propane gas source. If it is not a convertible gas pressure regulator, they are not alternative.
