Caution: The gas line should be installed by a qualified service person in accordance with all building codes. This section is intended as a guide for qualified technicians installing this appliance. Consult local and/or national building codes before proceeding.
A gas supply line access hole is located at the bottom right side of the Control Box. Gas valve inlet accepts a 3/8" N.P.T. fi tting. Correct gas line diameter must be used to assure proper operation.
The gas control is equipped with a capture screw type pres- sure test port, therefore it is not necessary to provide an 1/8 inch N.P.T. plugged tapping pressure port for checking gas pressure immediately upstream of the gas supply connection to the appliance.
