The gas inlet connection is 3/8" NPT, made at the rear of the main control. This unit comes with
an 18" gas flex pipe attached to the control valve at the factory. Run gas line into firebox from
either side and attach to gas flex pipe.
Test all gas joints from the gas meter to the heater for leaks using soap and water solution after
completing connection. DO NOT USE AN OPEN FLAME.

ran to either side of the
fireplace for ease of gas
connection.

GAS PRESSURE CHECK

The heater regulator controls the burner pressure which should be checked at the pressure test
point located on the right side of the main control and is accessible from the side of the gas log
assembly (see FIGURE 10).
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 2), contact your dealer and replace the regulator.
