Hearthstone Quality Home Heating Products, Inc
The gas fireplace is shipped with a 3/8" tube OD (male) connection. The gas supply piping should have a
separate gas shutoff valve and a 1/8" NPT plugged tapping upstream of the valve. The stove and its main
control valve must be disconnected from the gas supply piping system during any pressure testing of that
system at test pressures in excess of 1/2 psi (3.5 kPa). The stove must be isolated from the gas supply piping
system by closing the main control valve during any pressure testing of the gas supply system at test pressures
equal to or greater than 1/2 psi (3.5 kPa). After the gas supply has been connected, use a commercial gas leak
detector or apply a soapy water solution to all the fittings to check for gas leaks. Never use a flame to test for
leaks.
