Codes require that a gas shutoff valve must be installed in the gas line ahead of the steamer.
The burner is equipped with fixed gas and air orifices for use with natural or propane gas.
The gas line must be capable of delivering gas to the boiler without excessive pressure drop at the rate
specified on the rating plate.
The boiler is equipped with a factory preset pressure regulator. No further adjustment should be
required.
WARNING: PRIOR TO LIGHTING, CHECK ALL JOINTS IN THE GAS SUPPLY LINE FOR LEAKS.
USE SOAP AND WATER SOLUTION. DO NOT USE AN OPEN FLAME.
After piping has been checked for leaks, all piping receiving gas should be fully purged to remove air.
