Checking Gas Inlet Pressure
Step 1.
Turn "ON" all other gas appliances in the household, and;
Step 2.
Turn the fireplace burner “ON”.
If the pressure is not sufficient, ensure: 1) the piping used is large enough, 2) the supply regulator is
adequately adjusted, and 3) that the total gas load for the residence does not exceed the amount supplied.
The supply regulator (the regulator that attaches directly to the residence inlet or to the propane tank)
should supply gas at the suggested input pressure listed above. Contact the local gas supplier if the regulator
is at an improper pressure.
