Electrical Code,ANSI/NFPA 70 and/or Canadian Electrical Code Part I CSA C22.1, Electrical Code.
In the USA, maintain a clearance of at least 4 ft. horizontally from the vent terminal to gas meters,
electric meters, regulators and relief equipment. In Canada, maintain a 6 ft. clearance between
the vent terminal and these devices.

terminal block of the boiler (as shown in gure 12.5) keeping the same connections for the live wire
and the neutral wire.
