Gas Pressure Inadequate (Propane Running Empty)
Improper input pressure may lead to abnormal flame height or inability to achieve a clean flame. Follow
the procedure below to check input pressure.
! Whenever working with gas, make sure to follow the proper precautions.
This procedure opens the gas line - use extreme care.
! Do not press the piezo igniter until you are certain there is no gas leak or
gas buildup inside the firebox.
Note: Gas appliances on the same gas line may affect input pressure. Check input pressure
while the other appliances are on to see if pressure is correct.
Note: Make sure to check the propane level if using propane.
1 Turn the gas control knob to off.
2 Follow the directions below to access a gas port and attach a manometer (or other
pressure sensor).
Newer Models (with Gas Inlet Pressure-Test Port)
a Unscrew the gas inlet pressure-test port needle valve several turns.
b Place a tube over the needle valve port.
Gas Inlet Pressure-Test Port
3 Start the pilot, making sure to keep the test port covered the entire time.
4 Monitor the inlet pressure with the main burner on.
Warning: Gas will come out of the test port. Make sure to turn the gas control knob to off and
extinguish all flames prior to removing the tube.
Note: You may follow the same procedure to purge the gas line, monitoring for gas at the
needle valve location.
Remedy
Correct the gas inlet pressure. This may entail adjusting the regulator or increasing the pipe diameter.
