Find the control knob on the pressure regulator connected to the propane tank. Make sure the knob is turned to the Off position.
Go to the furnace, and turn the knob on the control panel to the Off position. Next, use an open-end wrench to remove the fitting where the gas line connects to the control box. To test the pressure, screw the fitting into an end-line pressure gauge. You should find the manufacturer's recommended pressure in the owner's manual; it also often appears on a label near the control box.
Turn the control knob on the regulator to the recommended pressure. Next, reference the pressure reading on the gauge. If it is too high or too low, adjust accordingly. Once the pressure is regulated, make a corresponding reference mark on the knob, and then turn it off.
Detach the gas line from the gauge, and reattach it to the control box. Turn the regulator knob to the correct setting. Finally, turn the control knob to the Pilot position, and wait five minutes before lighting the pilot light.
