thermal efficiency rating determined under continuous

operating conditions and was determined independently

of any installed system.
The appliance and its shutoff valves must be disconnected from the gas supply piping system during any

pressure testing where the pressure exceeds ½ PSIG (3.45 KPa) or damage will occur to the valve.
The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff

valve during any pressure testing of the gas supply piping system at test pressures equal to or less than

½ psig (3.45 KPa).
