vent-free gas logset. Have the line installed by a qualified service
person in accordance with all building codes. consult local building
codes to properly size the gas supply line leading to the 3/8-inch
hook-up at the unit. the state of Massachusetts requires that a
flexible appliance connector cannot exceed three feet in length.
Gas access holes are provided on both sides of the firebox.
