For any application involving processing gas in furnace, to ensure safe use of furnace flange, please always install the two stage gas regulator to the cylinder.
Read the furnace instruction to understand the pressure rating of each parts in system.
Determine and limit the input gas pressure before operation to avoid overpressure which could cause damages to pressure gauge, needle valve or other fittings.
Failure to install gas reguator could cause severe personal injury.
Installation
1. Connect the gas regulator to gas Cylinder.
Install a 1/4" tube fitting to the outlet of gas regulator.
2. Install another 1/4 tube fittings in the flange.
Use a 1/4 stainless steel or PTFE tube (low pressure) to connect the gas regulator and flange. NOTE : Make sure the thread type of the 1/4 tube fittings before installation.
For most gas reguator in U.S. the 1/4 tube fitting is required to have 1/4 MNPT thread type.
For MTI flange system, the 1/4 tube fitting is required to have 1/4 MBSPP thread type.
3. Finish Installation.
