lower right front of the unit. A manual valve must be
installer-supplied either inside or just outside of the wall
sleeve as appropriate per local codes and/or ANSI-Z223.1
or CAN/CGA-B149.

nection to the appliance.

requirements of local gas codes and/or ANSI-Z223.1
or CAN/CGA-B149. The appliance and its individual
shut-off valve must be disconnected from the gas supply
piping system during any pressure testing of that system
at test pressures above ½ PSIG (3.5 kPa).
Additionally, the appliance must be isolated from the gas
supply piping system by closing the appliance manual
valve during any pressure testing as described above.
