United States Stove Company 2020L - Manual (Page 13)

The heater regulator controls the burner pressure which should be checked at the pressure test
point located on the front of the main control and is accessible by removing the control panel
on the right side of the heater.
The pressure should be checked with the heater burning and the control set to high (HI).
The pressure regulator is preset and locked to avoid tampering. If the pressure is not as
specified in Product Specifications (Page 5), contact your dealer and replace the regulator.
The appliance and its individual shutoff valve must disconnected from the gas supply piping
system during any pressure testing of that system at test pressures in excess of ½ psi (35 kPa).

connector is suggested for easy connection.
Test all gas joints from the gas meter to the heater for leaks
using soap and water solution after completing connection.
