Connection to Mains Supply
The CM15BG and CMX15BG boilers must be installed in premises having a system impedance of not
more than 0.25 + j0.25Ω.
The CM15BG and CMX15BG boilers comply with the technical requirements of BS EN 61000-3-3.
The CM15BG and CMX15BG boilers must be installed in premises having a service capacity ≥100 A per phase.
Complete all the pipe-work before connecting the boiler to the electricity supply.
Any re-installation must be performed by qualified electricians.
Ensure that the mains voltage available coincides with that shown on the rating label.
