WARNING
The boiler and its gas 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 boiler 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 1/2 psi (3.5 kPa).
The boiler shall be installed such that the gas ignition system components are protected from water (dripping, spraying,
rain, etc.) during appliance operation and service (circulator replacement, condensate trap, control replacement, etc.)
The safety valve supplied with the gas boiler, has to be connected by the installer as shown in figure 2.1.
